Summary
We are seeking a highly skilled Module System Engineer specializing in test instrument
development for Camera and Battery module validation and characterization. This role focuses
on designing and developing sophisticated test equipment and measurement systems to
support comprehensive module testing throughout the product lifecycle. The ideal candidate will
possess deep electrical engineering expertise with extensive knowledge in test methodology
development, instrumentation design, and characterization techniques. Strong technical
proficiency is required in understanding electro-mechanical system architectures, optical-
electrical performance parameters for camera modules (including sensor characterization, ISP
testing, lens quality metrics, and power consumption profiling), and electrochemical testing
requirements for battery modules (including capacity measurement, impedance spectroscopy,
safety testing protocols, and thermal characterization). The engineer must have thorough
understanding of module design principles, specifications, and failure modes to develop
effective test solutions that ensure product quality and performance in consumer electronics
applications including smartphones, tablets, laptops, and wearable devices.
Beyond core test instrument development, this role demands hands-on involvement in factory
deployment of test systems, including real-time support for test equipment optimization during
prototype validation, developing automated test sequences and data collection systems, and
ensuring test coverage meets all product reliability and quality requirements. The engineer will
lead cross-functional Failure Analysis and Corrective Action (FACA) processes by providing
advanced diagnostic capabilities through custom test solutions, respond to production line
issues with specialized test equipment and measurement expertise, and drive systematic root
cause analysis using data acquired from purpose-built test instruments. This position serves as
a critical technical bridge between module design requirements, comprehensive validation
strategies, and scalable production test solutions, requiring expertise in both test instrument
architecture and practical implementation in high-volume manufacturing environments.
Description
Design and develop specialized test instruments for camera and battery module
validation, including optical measurement systems, electrical test fixtures, battery
characterization equipment, and automated data acquisition platforms
Create comprehensive test sequences, measurement algorithms, and software
interfaces to ensure accurate and repeatable module characterization across all critical
parameters
Define and implement factory-level testing strategies for module validation, including test
specifications, acceptance criteria, and standardized procedures for global
manufacturing sites
Deploy, commission, and optimize test equipment at production facilities, ensuring
proper calibration, correlation studies, and gauge R&R validation
Provide rapid response to line-down situations involving test equipment failures or
measurement issues through remote diagnostics and on-site technical support
Collaborate with manufacturing engineering, quality teams, and module suppliers to
optimize test coverage, improve yields, and reduce cycle time
Lead FACA investigations by developing specialized diagnostic tools and test
methodologies to identify root causes of module failures
Analyze test data trends and failure signatures to enhance detection capabilities and
implement preventive measures through improved test coverage
Maintain comprehensive test system documentation including design specifications,
calibration procedures, and ensure compliance with safety standards and regulatory
requirements
Participate in design reviews with module engineering teams to ensure adequate
testability and validation coverage throughout the product lifecycle
Partner with camera/battery module engineers, BMS teams, and software developers to
translate module specifications into comprehensive test requirements and validation
strategies
Interface with product validation teams and suppliers to ensure alignment between
design validation, production testing, and quality objectives
Minimum Qualifications
Bachelor's degree in Mechanical Engineering, Electrical Engineering, Materials Science,
or a related field
3+ years of hands-on experience in electrical design, development and factory testing
for consumer electronics
Experience in test equipment design, instrumentation development, or validation
engineering for PCB, Flex or SIP.
Experience with test system hardware design including fixture development and/or PCB
layout and/or interface circuitry for high-speed digital and analog signals
Preferred Qualifications
Master's degree in relevant engineering field
Proven ability to support factory builds, lead or contribute to FACA processes, and
manage line-down issue resolution in fast-paced production environments
Working knowledge of industry standards and test specifications (MIPI, I2C, USB, ACI,
SPMI etc.)
Familiarity with factory testing equipment, End2End validation methods, and data
interpretation for quality control
Excellent communication and collaboration skills to work effectively with cross-functional
teams including manufacturing, quality, BMS, and suppliers
Willingness to travel (25-40%) for factory support, supplier engagement,
and test equipment deployment
Programming or scripting proficiency (e.g., Python, MATLAB, LabVIEW, C++) for test
automation, data processing, or analysis
Experience with statistical analysis tools and methodologies (SPC, DOE, 6-Sigma)
