Senior Battery Test Engineer, Arbin/Maccor/Digatron

WHAT YOU’LL DO

• Enable extremely accelerated/aggressive battery development timelines by burning down risks at the cell, module, and pack level via development testing
• Support Battery System Engineers who support battery programs across Anduril with common test procedures/approaches at the cell, module, and pack level
• Design tools and protocols to enable efficient documentation of test procedures/results without adding significant time or wasted effort
• Write robust, modular data processing scripts and tools to efficiently provide plots/outputs that are required to enable informed system-level decisions
• Based on BMS/algorithm requirements- design robust and pragmatic test procedures to be executed iteratively at the model-in-loop (MIL), software-in-loop (SIL), and hardware-in-loop (HIL) levels
• Support validation of battery management system (BMS) algorithms, to include battery state handling, enable/disable switch (ie. contactor or FET) control, cell balancing, state-of-charge (SOC) estimation, state-of-health (SOH), state-of-power (SOP) power limits, fault handling, isolation monitoring, high-voltage interlock loop (HVIL), etc
• Collaborate with Development Test and Battery Systems engineers to characterize battery cell equivalent circuit models and deploy them to battery HILs or simulations

REQUIRED QUALIFICATIONS

• Bachelor’s Degree in related Engineering discipline, ideally with emphasis in battery development of some kind
• 3+ years of professional experience in a related engineering field
• Experience in an immersive interdisciplinary technical project (collegiate project teams or professional settings)
• Demonstrated validation of battery cells and modules/packs against system requirements
• Experience with battery testing equipment (e.g., Arbin, Maccor, Digatron, Chroma) for cell, module, and pack characterization and performance validation
• Capability to compress timelines without sacrificing product quality by way of prioritization and brute force
• Experience in hardware automation and software-hardware communication/integration
• Demonstrated proficiency/utilization of Python or Matlab to process large data files into plots, summaries, metrics, etc.
• Eligible to obtain and maintain an active U.S. Secret security clearance

PREFERRED QUALIFICATIONS

• Graduate Degree in Electrical Engineering, Software Engineering or Computer Science with applied focus on battery management systems
• Experience in BMS HW/SW validation methods- including software-in-the-loop (SIL/SITL), model-in-the-loop (MIL/MITL), and hardware-in-the-loop (HIL/HITL) testing
• Experience in cell equivalent circuit model (ECM) development and deployment to battery management systems
• Experience in battery characterization methods: mission profile validation, equivalent-circuit model characterization, cycle/calendar life assessment, safety features, etc.
• Demonstrated experience in battery modelling, controls, and module/pack integration
