Software Engineer - Firmware / Backend

We’re looking for a Firmware & Backend Software Engineer to take ownership of the Gynesis platform’s device firmware and back-end software in-house. This is a foundational role: firmware is regulated device software under our FDA 510(k) submission, and clean, well-documented, in-house-owned software is central to both getting this platform to market and building what comes after it.

You’ll own the controller firmware, the host-side data-extraction tool, and the accessory app’s backend - establishing the source ownership, documentation, and architecture discipline that carries Gynesis through submission and lays the foundation for our next-generation wireless (BLE) roadmap.

What You’ll Do

• Own the Gynesis device firmware in-house - waveform control, button/display logic, USB-C and power management - developed to IEC 62304.
• Produce submission-grade software documentation, a software bill of materials (SBOM), and cybersecurity artifacts to support our FDA 510(k) submission.
• Establish clean in-house source ownership, version control, and build processes, closing gaps left by prior development vendors.
• Author software requirements, architecture, and test protocols traceable to the submission.
• Ensure all software work meets FDA premarket cybersecurity, IEC 62304, and design-control expectations, partnering closely with Regulatory and Quality.
• Collaborate with the controller/hardware engineer on firmware-hardware integration and data interfaces.
• Lay the software architecture foundation for our next-generation wireless (BLE) device, companion app, and provider portal.
• Own the backend infrastructure supporting the accessory app, including authentication, data, APIs, and push notifications.

• 7+ years of embedded firmware (C/C++) and back-end/server-side software development experience.
• Experience with medical device software developed under IEC 62304, including cybersecurity and FDA software documentation.
• A track record of owning firmwarehost data interfaces and application backends (authentication, APIs, data).
• BLE/wireless development experience, and interest in helping architect our wireless V2 roadmap, is a strong plus.
