Applications Engineer, Battery System Architecture
CelLink Corporation, San Francisco, California, United States, 94199
Applications Engineer, Battery System Architecture
The Applications Engineer will be responsible for designing, developing, and executing flex circuit products from concept to development. The right person will have experience with battery systems, focusing on battery interconnects, cell connections, and pack architecture, to ensure optimal performance in EV and energy storage applications.
Base Pay Range $130,000 – $160,000 per year
Essential Duties and Responsibilities
Direct creation of 3D models and 2D drawings of current collector assemblies, battery interconnects, and voltage sense harnesses.
Selecting termination options for connecting to BMS/PCBA, such as welded, crimped, soldered, ZIF, etc.
Define requirements of flex circuit products based on internal, customer, and regulatory system-level requirements.
Build prototype circuits (hands‑on) and support launch activities.
Lead design reviews and DFM analysis.
DVP&R creation and execution to validate products along with DFMEAs and other pertinent APQP documentation.
Develop processes, designs, and material combinations to enhance the performance of CelLink's flexible circuits under various usage cases and applications.
Minimum Qualifications (Education, Knowledge, Skills, and Abilities)
Bachelor's Degree in materials science, EE, ME, physics, or equivalent.
Understand the requirements and performance of Li‑Ion batteries in all cell formats (pouch, prismatic, and cylindrical).
Experience in simulation (FEA and CFD) analysis and interpretation is preferred.
Experience with cell connection MFG processes such as laser‑welding, ribbon/wire bonding, ultrasonic welding, resistance welding, etc.
Knowledge of mechanical, electrical, and thermal material properties for common conductor materials, various types of plating, and insulating materials.
Ability to size busbars using simulations and 1D joule heating calculations.
Experience with the design and validation of electrical interfaces, joints, and connection methods.
Knowledge of pack architecture and battery sizing (series and parallel connections, nominal energy, power, etc.).
Benefits Medical insurance, vision insurance, 401(k), paid maternity leave, paid paternity leave.
