Systems Test Engineer

What you will do:
The Systems Integration/Test Engineer is responsible for defining developing and integrating Li-Ion and/or ultra-capacitor battery systems that meet OEM and regulatory requirements for low-voltage (12V-48V) automotive applications. This role involves developing and executing the integration and testing plans to ensure compliance with the functional performance and safety requirements of the system. This role requires collaboration with cross-functional teams to deliver safe reliable and high-performance energy storage solutions. This position is ideal for candidates with a strong background in system integration and testing (right side of the V-model) of power conversion modules such as DCDCs and battery technology.

How you will do it:
System Integration & Interfaces:
Define and manage thermal electrical and mechanical interfaces between the
battery pack BMS and vehicle powertrain.
Work closely with software mechanical and electrical teams to optimize system-level interactions.
Support Hardware-in-the-Loop (HiL) and Model-in-the-Loop (MiL) testing to
validate system integration.
System Integration & Verification:
Define electrical thermal and mechanical interfaces between the battery pack
ultra-capacitor system BMS and vehicle powertrain.

Collaborate with cross-functional teams to ensure seamless system integration and interface compatibility.
Lead the development of Design Verification Plans (DVPs) ensuring
comprehensive validation coverage for system performance durability and
compliance with OEM and regulatory standards.
Document verification coverage of all requirements with traceability in the
requirements management tool.
Participate in system-level validation durability testing and failure mode
analysis.
Support Hardware-in-the-Loop (HiL) Model-in-the-Loop (MiL) and system-level
validation to ensure robust performance.
Assist in aging studies thermal modeling and electrical load analysis for
predictive performance assessments.

Risk Management & Documentation:
Support system-level DFMEA ensuring proper alignment with subsystem and
component-level DFMEAs.
Support Process FMEA ensuring proper alignment with End-of-Line testing.
Cross-functional Collaboration & Leadership:
Act as a technical liaison between systems mechanical electrical thermal and software engineering teams as it pertains to integration and testing.

What we look for:

BS/MS in Electrical Mechanical Systems Engineering or related field (or
equivalent experience).
5 years of experience in automotive battery systems powertrain or
electrification projects.
Proficiency in requirements management tools (Jama DOORS) simulation tools (MATLAB Simulink) and validation frameworks.
OEM/Tier 1 experience in automotive battery systems is preferred.
