How to Apply to Korea Aerospace Industries (KAI)

Key Takeaways

KAI is South Korea's only full-spectrum aerospace prime — fixed-wing (T-50/FA-50, KF-21), rotary-wing (Surion, LAH), space (KOMPSAT, Nuri contributions), commercial structures (Boeing/Airbus), and emerging UAM — and hires accordingly across many engineering disciplines.
Most hiring happens in two structured public-recruitment windows per year (typically spring and autumn); applying outside those windows is possible but rare, so plan your timing around the cohort cycle.
The bar is Korean-defense-prime serious: written aptitude test, technical interview, presentation interview, and executive interview, plus a security background check before any offer is finalized.
Resumes must respect Korean form — 입사지원서 plus 자기소개서 essays for domestic roles, English CV plus Korean cover letter for global tracks — and lead with objective credentials (GPA, certifications, TOEIC/OPIc, military service).
Sacheon-based life is part of the deal for most engineering and manufacturing roles; willingness to relocate from Seoul or abroad is a real screening criterion, not a footnote.
Programs run for decades, so KAI rewards patience, ownership, and depth in a chosen discipline far more than rapid job-hopping or buzzword breadth.
Bilingual Korean-English engineers with export-program awareness (Poland FA-50PL, Iraq T-50IQ, Philippines FA-50PH, Indonesia KF-21 partnership) are an unusually strong fit given KAI's growing international business.
Defense-grade processes (AS9100, DO-178C/DO-254, MIL-STD, configuration management, export control) are non-negotiable; show in your resume and interview that you can operate inside that discipline.
Cultural fit matters — respect for hierarchy, integrity, long-term commitment, and clear formal Korean (존댓말) in interviews are scored alongside technical ability.

About Korea Aerospace Industries (KAI)

Korea Aerospace Industries, Ltd. (KAI, ko: 한국항공우주산업) is South Korea's flagship aerospace and defense manufacturer, headquartered in Sacheon, South Gyeongsang Province. Formed in 1999 through the consolidation of the aerospace divisions of Samsung Aerospace, Daewoo Heavy Industries, and Hyundai Space and Aircraft Company at the urging of the Korean government, KAI exists to give the Republic of Korea a fully sovereign capability to design, develop, produce, and sustain modern fixed-wing, rotary-wing, and space platforms. As of 2026 it employs roughly 5,500 staff, the majority concentrated at its Sacheon headquarters and adjacent assembly plants, with additional facilities and offices in Seoul, Daejeon, and at customer sites across the United States, Indonesia, the Philippines, Iraq, Poland, and Malaysia. The company is publicly listed on the Korea Exchange (KRX: 047810); the Korea Development Bank and the Export-Import Bank of Korea are among its largest shareholders, which gives KAI a unique hybrid identity as both a commercially run KOSPI-listed firm and a strategic national champion. KAI's product line is unusually broad for a company its size. On the fixed-wing side it produces the T-50 Golden Eagle family of advanced jet trainers and light combat aircraft, including the FA-50 light fighter that has been exported to Indonesia, Iraq, the Philippines, Thailand, Poland, and Malaysia, and it leads the KF-21 Boramae 4.5-generation multirole fighter program in partnership with the Republic of Korea Air Force, Indonesia, and a domestic supplier base of more than 700 firms. On the rotary-wing side KAI builds the KUH-1 Surion utility helicopter, the LAH/LCH light armed and civil helicopters jointly developed with Airbus Helicopters, and the upcoming Marine Attack Helicopter (MAH). KAI is also Korea's prime contractor for space systems, having built the bus and integration for Korea Multi-Purpose Satellite (KOMPSAT/Arirang) series, contributed to the Nuri (KSLV-II) launch vehicle, and stood up a growing satellite and UAM (urban air mobility) business. The company is a long-standing risk-sharing supplier to Boeing and Airbus, producing wing structures, fuselage sections, and sharklets for the 737, 787, A320, and A350. Working at KAI is therefore unusual: it combines the patient, decade-spanning rhythm of national defense programs with the export discipline of a commercial OEM and the regulatory rigor of a publicly traded aerospace firm.

Application Process

1
Watch the official KAI careers portal (recruit
Watch the official KAI careers portal (recruit.koreaaero.com) for biannual public recruitment windows (sangbangi/hangbangi, typically March-April and September-October) — most experienced and new-graduate roles are filled through these structured cohorts rather than rolling postings.
2
Create an account on the KAI recruitment site and complete the standardized Kore
Create an account on the KAI recruitment site and complete the standardized Korean application form (입사지원서), including the self-introduction essay (자기소개서) with prompts on motivation, growth experience, KAI-specific interest, and a professional vision statement; non-Korean applicants for global mobility programs apply through the English portal or via partnered universities.
3
Pass the document screening (서류전형), where recruiters score education, certificat
Pass the document screening (서류전형), where recruiters score education, certifications (engineering license/기사, defense security clearance eligibility, English ability via TOEIC/OPIc), military service status for male Korean applicants, and the quality of your essays.
4
Sit the KAI written aptitude test (필기전형)
Sit the KAI written aptitude test (필기전형) — a job aptitude exam (직무적성검사) covering verbal, numerical, spatial, and technical reasoning, plus a major-specific technical section for engineering tracks (aerospace, mechanical, electrical, materials, software, systems).
5
Complete the multi-stage interview cycle (면접전형): typically a job-fit/technical p
Complete the multi-stage interview cycle (면접전형): typically a job-fit/technical panel with the hiring department, a presentation interview where you defend a short technical or business proposal, and an executive/values interview assessing cultural fit, integrity, and long-term commitment.
6
Clear the security and background check (신원조회) required for defense work
Clear the security and background check (신원조회) required for defense work — KAI's facilities and programs (KF-21, T-50, classified subsystems) are subject to Defense Acquisition Program Administration (DAPA) and Ministry of National Defense rules, which require a clean record and, for many roles, Korean citizenship.
7
Attend the pre-employment health check and onboarding/orientation in Sacheon, af
Attend the pre-employment health check and onboarding/orientation in Sacheon, after which new hires usually rotate through a multi-week induction covering aerospace fundamentals, quality systems (AS9100), export control, and shop-floor safety before joining their assigned division.

Resume Tips for Korea Aerospace Industries (KAI)

recommended

Submit in the format KAI actually reads: a Korean-language 입사지원서 plus 자기소개서 essa

Submit in the format KAI actually reads: a Korean-language 입사지원서 plus 자기소개서 essays for domestic roles, and a clean 1-2 page English CV with a Korean cover letter for global/export-program roles — recruiters will distrust a US-style 'creative' resume for a Korean defense prime.

recommended

Lead with verifiable credentials: degree, major, GPA on the Korean 4

Lead with verifiable credentials: degree, major, GPA on the Korean 4.5 scale, university rank, plus engineering license (기사/산업기사 in 항공, 기계, 전기, 전자, 정보처리), TOEIC/OPIc scores, and any DAPA-relevant certifications — KAI screens hard on these objective fields before reading prose.

recommended

Quantify aerospace-relevant work with platform names and lifecycle phase: don't

Quantify aerospace-relevant work with platform names and lifecycle phase: don't write 'designed structural component', write 'sized composite wing rib for Class III UAV using ABAQUS, reducing mass 12% while meeting FAR 23 ultimate load' so reviewers can map you onto KF-21, KUH-1, or commercial wing programs.

recommended

Spell out tool fluency the KAI engineering office expects: CATIA V5/V6, NX, ENOV

Spell out tool fluency the KAI engineering office expects: CATIA V5/V6, NX, ENOVIA/Teamcenter PLM, ANSYS, ABAQUS, NASTRAN/PATRAN, MATLAB/Simulink, DOORS, MBSE (Cameo/Capella), and DO-178C/DO-254 for avionics and software roles — list the version and scope of work, not just the logo.

recommended

Make your military service and security posture explicit if you are a Korean mal

Make your military service and security posture explicit if you are a Korean male applicant: state branch, rank, MOS, and discharge status (병역사항 — 만기전역, 면제 사유 등); for foreign applicants, note any export-control or ITAR experience and willingness to relocate to Sacheon.

recommended

Show that you can operate in a regulated, document-heavy environment by citing A

Show that you can operate in a regulated, document-heavy environment by citing AS9100, MIL-STD-882 safety, MIL-HDBK-516, FAA/EASA part certifications, configuration management, or ISO/IEC 15288 systems engineering experience — KAI lives or dies by audit trails.

recommended

Emphasize Korean-language writing and reading ability honestly; even global role

Emphasize Korean-language writing and reading ability honestly; even global roles require participating in 회의 (meetings), reading internal 보고서 (reports), and navigating shop-floor instructions in Korean, so claim a TOPIK level you can defend in interview.

recommended

Tailor the 자기소개서 to KAI specifically — name a program (KF-21, FA-50PL for Poland

Tailor the 자기소개서 to KAI specifically — name a program (KF-21, FA-50PL for Poland, Surion, KOMPSAT-7, UAM), explain why that program matters to Korea's sovereign capability, and connect it to one concrete project of your own; generic essays are filtered out fast.

ATS System: KAI Recruit Portal (자체 채용 시스템)

Korea Aerospace Industries operates its own in-house recruitment portal at recruit.koreaaero.com rather than using a Western ATS like Greenhouse, Workday, or Lever. The portal is built around the standard Korean 입사지원서 (application form) and 자기소개서 (self-introduction essay) format used by major Korean conglomerates and defense primes. Applicants register an account, complete a structured biographical and credentials form (school, major, GPA, certifications, language scores, military service, awards, project experience), upload required documents, and answer essay prompts. The system filters on objective fields (degree, certifications, scores, service status) before recruiters read essays, then routes successful applicants through the written aptitude test, interviews, and security background check stages. The portal supports Korean primarily, with limited English support for designated global tracks; foreign applicants for international programs are sometimes routed through partner universities or dedicated global recruitment microsites linked from the main page.

Interview Culture

KAI interviews feel less like a Silicon Valley conversation and more like a structured, multi-panel evaluation in the tradition of large Korean conglomerates and defense primes.

Expect to be in Sacheon (or occasionally Seoul) for at least one full day. The first stage is typically a job-competency interview (직무면접) with three to five interviewers: the hiring team lead, a senior engineer or program manager, and an HR observer. You will be asked to walk through your résumé chronologically in Korean, defend a specific technical claim ('explain how you sized that spar', 'derive the lift distribution you used', 'why ABAQUS over NASTRAN here'), and respond to short brain-teasers grounded in fundamentals — fluid mechanics, control theory, structural analysis, embedded systems, or signals depending on track. Engineers should be ready to draw free-body diagrams or block diagrams on a whiteboard; software candidates may face a coding or pseudocode exercise plus DO-178C/MISRA-C process questions. The second stage is a presentation interview (PT면접 or 발표면접) where you are given a short prompt — a design trade study, a proposal abstract, or a problem-solving scenario — and 30-60 minutes to prepare a 5-10 minute talk on a whiteboard or paper, followed by a Q&A that pressure-tests your assumptions. The final stage is the executive/values interview (임원면접 or 인성면접) with two or three senior leaders. This is where KAI's cultural priorities surface: integrity (정직), responsibility (책임감), patience for long programs, willingness to relocate to Sacheon, comfort with hierarchy, and visible commitment to Korea's defense and aerospace sovereignty. Expect questions like 'why KAI and not Hanwha Aerospace or LIG Nex1?', 'tell us about a time you chose the harder right answer over the easier wrong one', 'how would you respond if a senior engineer disagreed with your analysis?', and 'are you prepared to spend ten years on a single program?' Group discussion (토론면접) is sometimes used for new-graduate cohorts, in which case demonstrate that you can listen, build on others' points, and reach consensus rather than dominate. Throughout, expect Korean business etiquette — bowing on entry, two-handed business card exchange, conservative dark suit, on-time arrival at least fifteen minutes early — and answer in clear, respectful 존댓말 (formal Korean). Foreign applicants may be allowed to interview in English for designated global tracks, but signaling Korean-language effort and cultural respect is non-negotiable.

What Korea Aerospace Industries (KAI) Looks For

Deep technical fundamentals over breadth — KAI prefers an engineer who can derive a result from first principles in their core discipline (aerodynamics, structures, propulsion, avionics, controls, materials, manufacturing) over a generalist who has touched many tools shallowly.
Long-horizon commitment and stability: programs like KF-21, KUH-1, and KOMPSAT span a decade or more, so the company values candidates who plan to stay, accept Sacheon-area life, and grow inside KAI rather than treat it as a stepping stone.
Demonstrable comfort with regulated, certified development — AS9100, DO-178C/DO-254, FAA/EASA/MOLIT certification basis, configuration management, traceable requirements, and the discipline to document everything.
Korean-language fluency for daily work plus useful English for export campaigns (Poland, Malaysia, the Philippines, Indonesia, the U.S.) — bilingual candidates who can bridge Sacheon engineering and overseas customers are highly prized.
Security and integrity profile compatible with defense work: clean background, eligibility for Korean security clearance, awareness of export control (ITAR, EAR, Korean Defense Trade Control), and discretion about classified material.
Hands-on familiarity with aerospace tooling and certification deliverables — CATIA, NX, ANSYS, ABAQUS, MATLAB/Simulink, DOORS, Cameo/Capella, PLM systems, plus shop-floor exposure for manufacturing and quality candidates.
Ownership and 책임감 (responsibility) — KAI rewards engineers who close a problem to root cause, write the report, present the fix, and stand behind the result through flight test or field deployment, even when it is uncomfortable.
Cultural fit with a Korean engineering organization: respect for hierarchy without sycophancy, willingness to participate in team rituals and after-hours collaboration, and a cooperative disposition that fits KAI's matrixed program-and-function structure.

Frequently Asked Questions

When does Korea Aerospace Industries open applications, and is there rolling hiring?

KAI primarily hires through two structured public-recruitment windows per year, usually around March-April and September-October, posted on recruit.koreaaero.com. Some experienced-hire and specialist roles open on a rolling basis, but the bulk of new-graduate and mid-career intake is concentrated in those cohorts, so plan your application timing around them and watch the portal in advance.

Do I have to be a Korean citizen to work at KAI?

For most engineering, manufacturing, and program roles tied to defense work (KF-21, T-50/FA-50, classified subsystems), Korean citizenship and eligibility for a Korean security clearance are practically required because of DAPA and Ministry of National Defense rules. Foreign nationals can be hired into specific commercial, export, space, or research roles, particularly where bilingual ability and export-market knowledge are needed, but the path is narrower and usually routed through global recruitment programs or partner universities.

Where will I actually work if I am hired?

The center of gravity is Sacheon in South Gyeongsang Province, where KAI's headquarters, main assembly plants, flight-test facility, and most engineering offices are located. There are smaller offices in Seoul (corporate, sales, government affairs), Daejeon (R&D ties), and at overseas customer sites in Indonesia, Iraq, the Philippines, Poland, Malaysia, and the United States. Willingness to relocate to the Sacheon area is a realistic prerequisite for engineering and manufacturing roles.

What majors and degrees does KAI hire most?

Aerospace, mechanical, electrical/electronic, materials, industrial, computer/software, and systems engineering are the largest pipelines, alongside applied physics and aerodynamics for R&D. Business, finance, accounting, legal/contracts, supply chain, and international relations majors are hired for staff functions, especially supporting export programs. Master's and PhD degrees are valued for research, certification, and advanced design roles, but a strong bachelor's with relevant project experience is competitive for entry-level positions.

How important are TOEIC/OPIc and other Korean exam scores?

Very. KAI uses standardized scores as objective screening filters in the document phase. Competitive candidates typically present TOEIC 800+ or OPIc IM2/IH and above for general roles, with higher bars for export-program and global tracks. Engineering license certifications (기사, 산업기사) in your major are weighted heavily, and computer science roles benefit from 정보처리기사. Don't pad — recruiters verify.

What does the written aptitude test cover?

The KAI 직무적성검사 follows the Korean conglomerate template: verbal reasoning, numerical reasoning, spatial/figure reasoning, and a track-specific technical section. Engineering candidates should review fundamentals in their major (aero: aerodynamics, structures, propulsion; ME: solid mechanics, thermodynamics; EE: circuits, signals, controls; CS: data structures, algorithms, OS basics). Practice books for SK/Hanwha/LIG-style tests are reasonable preparation since formats are similar.

How should male applicants handle Korean military service status on the resume?

Be explicit. Include a 병역사항 line stating service status (만기전역/복무 중/면제), branch (육군/해군/공군/해병대), rank at discharge, MOS, and dates. Service in technical or aviation MOS is a small plus, but the main point is unambiguous compliance — ambiguous or missing entries are a red flag in defense hiring.

Can I interview in English?

For designated global or English-track roles, yes — typically those tied to overseas program offices, export campaigns, or specific R&D collaborations. For the vast majority of domestic engineering and staff roles, expect interviews in Korean, including the technical, presentation, and executive panels. Even on English-allowed tracks, demonstrating respectful Korean and basic 존댓말 etiquette signals long-term fit.

How long does the KAI hiring process usually take?

From application to offer is typically eight to twelve weeks for cohort hiring: about two weeks of document screening, one to two weeks to the written exam, two to three weeks to the technical interview, one to two weeks to the executive interview, then security background check and health screening before formal offer. Experienced-hire pipelines can be faster (four to eight weeks) but include the same security check, which is the most variable step.

What is the working culture like inside KAI?

It blends Korean conglomerate hierarchy with the patient, document-driven cadence of an aerospace prime. Programs run for years, decisions are made through formal review gates, and seniority and 책임감 (responsibility) carry real weight. Engineers spend significant time on certification artifacts, design reviews, and shop-floor coordination in Sacheon. Compensation, stability, and pension are competitive for Korean industry, and KAI is widely regarded as a prestigious place to build a long aerospace career, but it is not a fast-paced startup environment.
