Senior Embedded Firmware Engineer
About The Position
Brelle engineers next-generation platforms for supercars and superbikes, working alongside high-performance brands in the US and Europe. Our innovations are built on a novel battery pack architecture, a full-stack software platform, and automated manufacturing. Joining the team means working on making electric vehicles—on the road and on the racetrack—lighter, more engaging, safer, and capable of charging in minutes. Our engineering teams are structured like small Skunkworks teams – nimble, cross-functional, and technical. Engineers are encouraged to explore new concepts and materials and expected to rapidly go from idea to prototype. As a Senior Firmware / Software Engineer, you will be a core technical owner of Brelle's embedded platform, building the software foundation that powers a vehicle embedded architecture, ECUs, and developer services. You will shape how our embedded software is designed and scaled across hardware variants and customers. This includes RTOS selection and configuration, low-level driver development, bootloaders, diagnostics, and the platform abstractions that enable safe, reliable application development. This is a hands-on role where you’ll work closely with electrical, battery, systems, and vehicle teams to release new ECUs—debugging hardware in the lab, and validating functionality on benches as well as in superbike and supercar programs.
Requirements
- 5+ years developing production firmware in C/C++ for resource-constrained embedded systems
- Bachelor's or Master's degree in Electrical Engineering or Computer Science
- Deep understanding of RTOS concepts: task scheduling, priority inversion, semaphores, queues, memory pools, and real-time constraints
- Experience writing device drivers for MCU peripherals and debugging
- Expert with version control (Git), build systems and CI/CD pipelines
- Strong foundation in memory management, and embedded systems fundamentals
Nice To Haves
- Experience with automotive software development (AUTOSAR, ISO 26262, ASPICE) or other safety-critical domains
- Background at leading EV companies or automotive Tier 1 firmware suppliers
- Familiarity with FreeRTOS, SafeRTOS, or other real-time operating systems
- Familiarity with NXP toolchain & SDKs
Responsibilities
- Write, review, and release production-grade firmware for MCU peripherals and external components (SPI, I2C, UART, CAN/CAN-FD, ADC, DMA, timers etc), with a strong emphasis on code quality, testability, and long-term maintainability
- Architect and maintain clean abstractions across the embedded stack—RTOS, drivers, middleware, and application layers
- Contribute to the development and adoption of AI-enabled tooling for embedded firmware, helping automate boilerplate code, enforce architectural patterns, and improve test coverage across complex ECU platforms
- Play a core role in the structure and evolution of the embedded codebase, including repository organization, build systems, and versioning strategies that support multiple customers, programs, and hardware variants
- Lead ECU bring-up from first power-on through validation
- Implement and support diagnostics and vehicle communication (UDS, CAN, CAN-FD, Ethernet, LIN) to production standards
- Work hands-on with vehicle and systems teams to integrate Brelle ECUs into active superbike and supercar programs
Benefits
- Medical (HMO, PPO), Dental, and Vision
- 401(k)
- Flexible PTO
- Team meals 2x per week
- Monthly team events
- Founding Engineer equity participation through Employee Incentive Plan
