About the role

  • We are looking for a curious, detail-oriented, and self-motivated Staff Firmware Engineer to join our small firmware team and help shape the future of our medical devices.
  • This role also plays a key part in shaping firmware-side cybersecurity decisions.

Responsibilities

  • Own firmware projects from concept through release, including requirements, scoping, architecture, implementation, integration, and support for verification and release activities.
  • Guide firmware-side cybersecurity decisions in partnership with product security, including areas such as cryptographic design choices, secure boot and bootloader strategy, key hierarchy and storage, and secure firmware update or FOTA design.
  • Develop high-quality firmware for resource-constrained, MCU-based embedded systems with a strong emphasis on reliability, readability, and maintainability.
  • Lead deep root cause investigations for complex and sometimes rare product issues across firmware, hardware, manufacturing, wireless, power, and system interactions.
  • Contribute to documentation and design control artifacts in compliance with IEC 62304, ISO 13485, and related development processes.
  • Mentor junior engineers through design discussions, code reviews, and day-to-day technical guidance.
  • Use lab equipment and hands-on debugging techniques to bring up hardware, characterize issues, and validate behavior on-device.
  • This is a hands-on staff-level role for an engineer who can own firmware projects end to end: understanding product needs, defining scope, making architecture decisions, implementing robust code, and mentoring other engineers along the way.
  • Every day, we collaborate, create, and constantly reimagine what's possible.

Requirements

  • Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
  • 10+ years of hands-on firmware development experience in resource-constrained embedded systems, preferably MCU-based and bare-metal.
  • Experience owning substantial firmware work or projects from architecture through implementation and release.
  • Strong proficiency in C for embedded systems.
  • Strong experience with board bring-up, lab debugging, and hardware and firmware integration.
  • Experience investigating complex system issues and driving root cause to resolution.
  • Experience working cross-functionally with hardware and software teams in a structured development environment.
  • Success in this role requires strong technical judgment, attention to detail, and the ability to make sound decisions in a regulated environment with product, system, and patient impact in mind.

Nice to have

  • Experience with connected, wireless, or battery-powered embedded devices.
  • Familiarity with technologies such as BLE or cellular connectivity.
  • Familiarity with coding standards such as MISRA and with peer code review practices.
  • Experience with static and dynamic code analysis techniques for firmware development.
  • Experience with version control, release processes, CI/CD, test infrastructure, or other development tooling improvements.
  • What's in it for you:
  • $190,000.00 - $247,000.00
