About Mosaic Fertilizantes

Mosaic Fertilizantes is the Brazilian operating arm of The Mosaic Company (NYSE: MOS), the Tampa, Florida-headquartered global producer of phosphate and potash crop nutrients. The Brazilian unit was created in January 2018 when Mosaic closed its approximately US$2.5 billion acquisition of Vale Fertilizantes, taking over the integrated phosphate and potash assets that Vale had assembled through earlier purchases of Bunge and Fosfertil. That deal turned Brazil into Mosaic's largest country footprint outside the United States and made the company the dominant domestic-source fertilizer producer in a country that imports roughly 85 percent of the nutrients its agribusiness needs. The Brazilian headquarters is in Sao Paulo, with a finance and commercial hub that interfaces with Tampa and the global S&OP cycle. Operationally, the heavy footprint sits in Minas Gerais and Goias: phosphate rock mining and beneficiation at Araxa (MG), Tapira (MG), Catalao (GO), and the Patos de Minas / Patrocinio cluster (MG), plus chemical complexes that produce sulfuric acid, MAP, DAP, SSP, TSP, and feed-grade phosphates. Potash comes from Taquari-Vassouras in Sergipe, the only operating potash mine in Brazil, which makes Mosaic strategically important to the federal Plano Nacional de Fertilizantes program that aims to reduce import dependence on Russia, Canada, Belarus, Morocco, and China. Logistics moves through the ports of Paranagua (PR) and Santos (SP) plus inland warehousing close to the soy and corn frontier in Mato Grosso, Goias, and the MATOPIBA region. The Brazilian organization employs roughly 8,000 people across mining, processing, logistics, agronomy, sales, and corporate functions. CEO of Mosaic Fertilizantes is Bruno Lolli (verify the current incumbent on the Mosaic Brasil press page or LinkedIn before referencing in interviews, since the leadership has rotated since the Vale acquisition). The customer base is concentrated in large grain and sugarcane operators (SLC Agricola, Amaggi, Cosan, Sao Martinho), protein integrators (BRF, JBS-affiliated grain businesses), and the cooperative system (Coamo, Cocamar, Comigo, C.Vale), with a large smallholder distributor network reaching Cerrado producers. Competition is real and growing. Yara Brasil (Norwegian Yara), Heringer (with LGG having taken a stake in 2023), Fertipar, OCP Brasil (Moroccan), Eurochem (Russian, with sanctions-driven uncertainty), K+S Brasil, the Canadian junior Verde Agritech, and Petrobras's stated plans to restart its idled fertilizer plants all compete for the same farmer wallet share. Mosaic's edge is the integrated mine-to-bag domestic supply chain, the MicroEssentials and Granulado specialty blends, and decades of agronomic field data. If you are joining, expect a Portuguese-first work environment with English used routinely for Tampa liaison, a CLT employment relationship governed by Brazilian labor law and union conventions, and the cultural reality of working for a US-listed company whose quarterly results are dragged around by phosphate and potash benchmark prices, USD/BRL volatility, Russia-Ukraine trade flows, and the Brazilian crop cycle.

Add union, professional, and conselho registrations where applicable: CREA for engineers, CRA for administrators, CRC for accountants, OAB for legal, plus SINDIEXTRA or other state mining union memberships if held.

ATS System: Gupy

Mosaic Fertilizantes uses Gupy (app.gupy.io/mosaic), the dominant Brazilian recruiting SaaS, which combines a careers portal with an AI-driven ranking layer that scores candidates against the requisition. Recruiters work primarily from the Gupy aderencia ranking and only manually open the top tier for human review, so the application has to be optimized for the Gupy parser and questionnaire, not for a generic global ATS.

  • Create one Gupy profile and reuse it across requisitions; Gupy tracks application history and recruiters can see prior applications and rejections.
  • Upload the CV as a clean PDF generated from Word; avoid scanned images and avoid fancy two-column layouts that the Gupy parser fragments.
  • Answer every screening question fully and truthfully; questions about CLT pretensao salarial, English level, and disponibilidade para mudanca are knockout filters.
  • Record the optional video pitch when offered; Gupy flags candidates who skip it as lower engagement and many Mosaic recruiters use the video as a tiebreaker.
  • Mirror the requisition language in your profile: if the job title is 'Engenheiro de Processos Pleno', use that exact phrasing in your skills and summary so the parser tags the match.
  • Keep your Gupy profile updated quarterly because Mosaic recruiters search the Gupy talent pool for new requisitions before posting publicly.
  • Enable Gupy notifications via email and WhatsApp; missed messages are interpreted as low interest and the requisition moves on quickly.

Interview Culture

Mosaic Fertilizantes interviews follow a structured, behavior-based pattern with safety as a non-negotiable cultural gate.

Expect a Talent Acquisition screen, two to four technical and peer interviews, and a final HRBP or leadership conversation. Panels are common for senior corporate roles in Sao Paulo, while mine and plant roles tend to use sequential one-on-ones with the area leader, the maintenance or operations supervisor, and a HSE representative. Most interviews run in Portuguese; corporate, finance, IT, supply chain, and senior commercial roles routinely add an English segment with Tampa or regional stakeholders, sometimes via Microsoft Teams. The behavioral framework leans on STAR storytelling tied to Mosaic's stated values, with safety, integrity, and operational excellence weighted most heavily. Candidates who cannot give a concrete example of stopping work for a safety concern, or of escalating a near-miss, will struggle in operational interviews regardless of technical strength. For commercial and agronomy roles expect deep questioning on customer relationships, crop cycles, and how you have handled volatile USD-pegged commodity pricing in past sales conversations. Technical depth varies by track. Mining, geology, metallurgy, process, maintenance, and reliability roles expect concrete numbers from prior work and willingness to whiteboard mass balances or P&ID logic. FP&A and treasury candidates should be ready for a modeling case in Excel and a discussion of phosphate and potash benchmark dynamics. IT and digital roles increasingly include a system design or data pipeline conversation given Mosaic's SAP S/4HANA backbone and growing use of Azure and Snowflake. Dress is business casual in Sao Paulo and field-appropriate at sites; if you are interviewing at a mine, expect a site tour with PPE provided. Decisions are typically communicated within one to three weeks. Counter-offers are normal but the salary band is enforced by HR, so most negotiation room sits in relocation, sign-on, and PLR target rather than base.

What Mosaic Fertilizantes Looks For

  • Demonstrated safety leadership: a real story about stopping production for a hazard, leading a root cause analysis, or driving a measurable reduction in TF and TG.
  • Operational discipline and a bias for standardization, since Mosaic runs a global Mosaic Production System modeled on lean manufacturing principles.
  • Comfort with the commodity cycle: candidates who understand that phosphate and potash prices swing with global S&D, Russian and Belarusian export policy, and the Brazilian crop cycle, and who do not panic when results compress.
  • Bilingual capability for corporate roles; fluency in Portuguese is mandatory and English is the working language with Tampa for most exempt-level positions.
  • ESG fluency and post-Brumadinho mining sensitivity: ANM compliance, ICMBio relationships, tailings dam audits, community engagement, and a credible story about social license to operate.
  • Customer-centric thinking for commercial roles: ability to talk crop economics with a fazendeiro or cooperative buyer, not just sell a bag of MAP.
  • Cross-functional collaboration between Sao Paulo corporate and the operating sites, which sit hours away by car or by company turboprop and have their own culture.
  • Resilience for mine and plant work: 12-hour shifts, remote rotations, intermittent housing in Patrocinio or Catalao, and exposure to dust, heat, and chemical environments.
  • Integrity under audit: Mosaic is SOX-compliant as a US-listed company, and SOX testing reaches deep into Brazilian operations, finance, and procurement.
  • Long-term orientation: Mosaic invests on five- to ten-year mine plans, and the people who succeed are willing to grow inside the asset rather than rotating out every 18 months.

Frequently Asked Questions

Is Mosaic Fertilizantes the same company as The Mosaic Company?
Mosaic Fertilizantes is the Brazilian operating subsidiary of The Mosaic Company, which is headquartered in Tampa, Florida and listed on the NYSE under ticker MOS. The Brazilian unit was formed in 2018 when Mosaic acquired Vale Fertilizantes for about US$2.5 billion, taking over Vale's phosphate and potash assets in Minas Gerais, Goias, and Sergipe. Brazilian operations report into the global Mosaic structure but have a dedicated Brazil leadership team based in Sao Paulo.
What ATS does Mosaic Fertilizantes use in Brazil?
Mosaic Fertilizantes uses Gupy, the dominant Brazilian recruiting platform, at app.gupy.io/mosaic. All applications run through Gupy, which ranks candidates by an aderencia score before recruiters review profiles. Bypassing Gupy with a direct email almost never works because the requisition owner only sees candidates inside the system.
Where are the main Mosaic Fertilizantes work locations?
The corporate headquarters is in Sao Paulo. Phosphate mining and chemical operations sit in Minas Gerais (Araxa, Tapira, Patos de Minas, Patrocinio) and Goias (Catalao). The Taquari-Vassouras potash mine is in Sergipe and is the only operating potash mine in Brazil. Logistics flows through the ports of Paranagua (PR) and Santos (SP), and there is a network of inland warehouses serving the soy and corn frontier.
Do I need to speak Portuguese to work at Mosaic Fertilizantes?
Yes for almost every Brazil-based role. Portuguese is the primary working language across operations, plant floors, commercial offices, and HR. English is required as a second language for corporate, finance, IT, supply chain, treasury, legal, and senior commercial roles that interface with the Tampa parent. Site-level operational roles can run entirely in Portuguese.
What employment contract does Mosaic Fertilizantes offer?
Standard CLT (Consolidacao das Leis do Trabalho) employment contracts under Brazilian labor law, including 13th salary, paid vacation with the constitutional one-third bonus, FGTS, INSS, and the relevant union convention for the site or function. PJ contracts are rare and usually limited to specific specialist scopes. PLR (Participacao nos Lucros e Resultados) is paid annually based on Mosaic and Mosaic Fertilizantes performance against targets.
How does Mosaic Fertilizantes handle safety and environmental risk after Brumadinho?
Brumadinho was a Vale dam failure, not a Mosaic facility, but it reshaped the entire Brazilian mining sector. Mosaic Fertilizantes operates under ANM (Agencia Nacional de Mineracao) regulation, conducts independent tailings audits, and treats dam safety, water management, and community engagement as board-level topics. Candidates should expect interviewers to test ESG awareness and a personal track record of safety-first decision making.
Will I be expected to relocate to a mine site?
It depends on the role. Sao Paulo corporate roles are office-based with periodic site visits. Mining, processing, maintenance, reliability, HSE, and plant operations roles are based at Araxa, Tapira, Catalao, Patrocinio, or Taquari-Vassouras, and relocation packages are offered when needed. Be honest with the recruiter about your willingness to relocate; mismatched expectations late in the process are a common rejection reason.
How is compensation structured?
A salario base set against Mosaic's internal grade and the local market for the function and region, plus an annual PLR target tied to corporate and unit performance, plus the standard CLT benefits envelope (health insurance, dental, life insurance, meal vouchers, transportation, and pension or previdencia complementar for eligible bands). Mine and plant roles include shift premiums, hazard pay where applicable, and union-negotiated overtime rules.
What is the interview process timeline?
Two to four weeks from first Gupy contact to offer is typical for corporate roles. Operational and senior leadership roles can extend to six to eight weeks because of multiple interview rounds, site visits, and reference checks. Background check and admissional medical exam (ASO per NR-7) add another one to two weeks before the CLT contract is signed.
Who are Mosaic Fertilizantes' main competitors in Brazil?
Yara Brasil (Norwegian Yara), Heringer (with LGG having taken a stake in 2023), Fertipar, OCP Brasil (Moroccan), Eurochem (Russian, with sanctions-related uncertainty), K+S Brasil, the Canadian junior Verde Agritech, and Petrobras's stated plans to restart its idled fertilizer plants. The competitive battleground is the soy, corn, sugarcane, cotton, and coffee belts, with cooperatives and large grain operators as the most contested accounts.
How exposed is Mosaic Fertilizantes to global commodity cycles?
Heavily. Phosphate and potash benchmark prices, set in USD against international S&D, drive revenue. Russia-Belarus export policy, China's export quotas, Morocco's pricing posture, and the Brazilian crop calendar all affect realized margins. The USD/BRL rate moves both revenue and the cost of imported inputs. Candidates should expect interviews to probe how they reason about cyclicality and how they would protect the business across the cycle.
Does Mosaic Fertilizantes hire interns and trainees?
Yes. The company runs a Programa de Estagio for university students, typically posted on Gupy and through partner programs like CIEE, and a Programa de Trainees for recent graduates that rotates across operations, commercial, and corporate functions. Selection is competitive and uses online assessments, group dynamics, and panel interviews; Portuguese fluency is mandatory and English is a strong differentiator.
