Firmware Engineer

Apeiron Labs • Cambridge, MA

About The Position

We are looking for a firmware engineer with a proven track record of developing embedded software for robotic and electromechanical systems. The ideal candidate is hands-on and hardware-aware. They can move from the lab bench to the code editor with ease—and they understand that great embedded software is built in partnership with electrical, mechanical, and systems engineers. For us, remote work might mean deploying systems in the ocean, watching your creations dive, and surfacing with data that changes everything. If you've got an adventurer's soul, you're our kind of engineer.

Requirements

• BS or MS in Electrical Engineering, Computer Engineering, or related discipline.
• 5+ years of embedded systems experience, with a focus on bare-metal and RTOS development.
• Deep expertise with STM32 microcontrollers (HAL, LL, CubeMX, peripheral bring-up, interrupt-driven design).
• Strong C/C++ skills and familiarity with embedded software best practices (state machines, modular design, fixed-point math, etc.).
• Experience with debugging tools (JTAG/SWD, logic analyzers, oscilloscopes), and profilers.
• Familiarity with CAN, UART, SPI, I2C, and RS-485 interfaces.
• Comfort working in a fast-paced, hardware-rich R&D environment.
• US Citizenship required.
• The mindset to rapidly iterate in startup time is required.

Nice To Haves

• Experience developing firmware for underwater or harsh-environment robotics systems.
• Knowledge of motion control (PID, sensor fusion, encoders, etc.).
• Familiarity with low-power system design and sleep-state management.
• Proficiency with scripting languages (Python, Bash) for automation and tooling.
• Prior experience with software safety standards, unit testing, or static analysis.
• Sea trial or field experience in support of deployed systems.
• Experience with continuous integration systems (e.g., GitHub Actions, Jenkins, etc.).

Responsibilities

• Architect and implement embedded firmware for autonomous ocean vehicles, working directly on mission-critical systems such as power management, motor control, sensor acquisition, and communications.
• Own and evolve our STM32 firmware libraries and HALs, driving clean modular architecture across a growing codebase.
• Bring up new hardware platforms in the lab—bootloaders, debug tools, oscilloscopes, and all.
• Participate in and guide full-system bring-up and integration, working shoulder-to-shoulder with electrical and mechanical engineers.
• Build automated test frameworks and CI pipelines that ensure reliable, testable firmware.
• Support sea trials and offshore testing, debugging, and iterating rapidly in the field.
• Provide technical leadership, mentor junior engineers, and shape the engineering culture of the team.
• Contribute to a strong culture of documentation, peer review, and continuous improvement.
