Under limited supervision, the Senior Software / Firmware Developer will design, develop, test, and maintain embedded software and firmware for Battery Management System (BMS) products and related electronics platforms. This role focuses on low-level firmware running on microcontrollers and processors integrated directly onto PCBs, as well as higher-level software tools used for configuration, diagnostics, manufacturing, and validation.

The ideal candidate has deep experience programming hardware-adjacent systems, working closely with electrical engineers on schematic, PCB layout, bring-up, and debugging. This role collaborates with cross-functional teams including electrical engineering, systems engineering, test engineering, and program management to deliver reliable, safety-critical BMS solutions for aerospace, defense, and energy storage applications.

• Design, develop, and maintainembedded firmwarefor microcontrollers and processors used in BMS and power electronics systems.
• Program PCBs at the hardware level, includingboard bring-up, bootloaders, peripheral configuration, and low-level drivers.
• Implement firmware in Embedded C/C++, with supporting applications and tools in Python and C#.
• Develop communication stacks and interfaces for BMS systems, including
  
  CAN, CAN-FD, Drone
  
  CAN, SPI, I²C, UART, USB, and Ethernet.
• Collaborate with electrical engineers during schematic review, PCB layout, and design trade studies to ensure firmware-hardware alignment.
• Perform firmware validation, regression testing, and fault injection testing; maintain software test plans and test matrices.
• Debug complex system issues using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and software instrumentation.
• Develop manufacturing, calibration, and diagnostic tools to support production and field deployment.
• Support system-level integration, including interaction with power electronics, sensors, cell monitoring ICs, and safety circuits.
• Generate and maintain technical documentation including software architecture documents, interface control documents (ICDs), and user guides.
• Research and evaluate new tools, frameworks, and embedded technologies to improve product robustness and development efficiency.
• Other job-related duties as assigned.

Education & Experience:

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or related discipline required.
• 7+ yearsof professional experience in embedded software and firmware development.
• Demonstrated experience programmingmicrocontroller-based PCBsfrom bring-up through production.
• Strong proficiency in Embedded C/C++,Python, andC#.
• Experience with real-time or bare-metal systems, including interrupt handling, timing analysis, and memory-constrained environments.
• Experience working directly with hardware teams onBMS, power electronics, or safety-critical systems.
• Familiarity with version control systems (Git) and structured software development workflows.

• Prior Battery Management System (BMS) development experience.
• Experience with distributed BMS architecturesor large-scale battery packs (BESS, aerospace, EV, or defense).
