Position Overview:

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.

Functions:

* Design, develop, and maintain embedded firmware for microcontrollers and processors used in BMS and power electronics systems.

* Program PCBs at the hardware level, including board 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.

Requirements:

Education & Experience:

* Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or related discipline required.

* 7+ years of professional experience in embedded software and firmware development.

* Demonstrated experience programming microcontroller-based PCBs from bring-up through production.

* Strong proficiency in Embedded C/C++, Python, and C#.

* Experience with real-time or bare-metal systems, including interrupt handling, timing analysis, and memory-constrained environments.

* Experience working directly with hardware teams on BMS, power electronics, or safety-critical systems.

* Familiarity with version control systems (Git) and structured software development workflows.

Nice to Have

* Prior Battery Management System (BMS) development experience.

* Experience with distributed BMS architectures or large-scale battery packs (BESS, aerospace, EV, or defense).

* Experience with Ruby on Rails for internal tools, dashboards, or web-based configuration systems.

* Knowledge of functional safety concepts (fault detection, redundancy, watchdogs, fail-safe design).

* Experience supporting manufacturing test, field diagnostics, or OTA update systems.

Knowledge,

Skills and Abilities

(KSAs):

* Strong understanding of embedded systems architecture, hardware-software interfaces, and PCB-level design considerations.

* Ability to read and interpret electrical schematics and datasheets to support firmware development and debugging.

* Demonstrated ability to work independently while coordinating closely with multidisciplinary engineering teams.

* Strong problem-solving skills with the ability to diagnose complex, cross-domain issues (hardware, firmware, systems).
