Systems Integration / 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.

What you get:

Medical, dental and vision care coverage and a 401(k) savings plan with company matching – all starting on date of hire

Tuition reimbursement, perks, and discounts

Parental and caregiver leave programs

All the usual benefits such as paid time off, flexible spending, short-and long-term disability, basic life insurance, business travel insurance, Employee Assistance Program, and domestic partner benefits

Global market strength and worldwide market share leadership

HQ location earns LEED certification for sustainability plus a full-service cafeteria and workout facility
