Job description

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

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
• 7+ 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
• 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
