About The Position

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-the-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
