Embedded Firmware Engineer - Stealth Startup Opportunity
Are you an embedded firmware engineer who thrives close to the hardware? We’re a stealth-mode startup developing next-generation grid-connected energy storage systems, and we’re looking for someone to build robust, real-time embedded software at the core of our products.
What You'll Do:
* Design and develop real-time embedded firmware for STM32-based systems controlling high-power electronics
* Implement reliable, deterministic code for time-critical applications (control, communications, safety, monitoring)
* Work closely with power electronics and systems engineers to bring up new hardware from early prototypes through production
* Debug complex issues across firmware, hardware, and system boundaries using scopes, logic analysers, and other lab tools
* Contribute to firmware architecture, coding standards, and test strategies as the system evolves
What We're Looking For:
* (Required) Strong experience developing real-time embedded firmware in C/C++ on microcontrollers (STM32 or similar)
* (Required) Solid understanding of real-time constraints, interrupts, timers, DMA, and low-level peripherals
* (Required) Experience with bare-metal and/or RTOS-based systems (e.g. FreeRTOS or similar)
* (Required) Comfortable working with incomplete specs, evolving requirements, and tight timelines in an early-stage environment
* (Ideal) Experience with embedded communications (CAN, UART, SPI, I²C, Ethernet), bootloaders, or field updates
* (Required) Typically 3+ years in embedded firmware roles, but we care more about what you’ve built than years on a CV
You’ll be part of a small, driven team where your firmware will directly influence system performance, reliability, and safety. If you enjoy owning real-time systems, working hands-on with hardware, and building foundational technology in a stealth-mode startup, we’d love to hear from you.
