Senior/Lead Embedded Software Engineer

About the job

At Atmo Biosciences, we've developed an ingestible gas-sensing capsule that measures gut health from the inside. With FDA clearance secured and commercial momentum building, we're now looking for a Senior/Lead Embedded Software Engineer to help us scale what we've started.

This is a role where your code reaches all the way from firmware to the cloud — and where what you ship helps clinicians diagnose conditions affecting more than 40% of people worldwide.

What you'll do

• Design, develop and debug embedded firmware and software for medical devices under IEC62304
• Architect and own software systems end-to-end — from concept through to production deployment
• Integrate hardware and software components, and maintain deployed systems
• Lead, mentor and coach software engineers on the team
• Contribute to risk analysis and ensure compliance with quality standards (IEC62304, IEC62366, ISO13485)
• Drive continuous improvement and help lift the team's technical capabilities

What you bring

• 8–15+ years of software experience, with expert-level C++ and strong Python
• Embedded firmware development and hardware-software integration experience
• Hands-on with containerisation, DevOps, and Azure
• Demonstrated experience in regulated medical device development
• Strong electronics foundations and a talent for first-principles thinking
• A degree in Computer Science, Mechatronics, Electronics Engineering, or similar

Why Atmo?

We're a growing medtech company with FDA-cleared technology, a world-class medical advisory board, and a real clinical impact. You'll work alongside brilliant co-founders, a strong R&D team, and a leadership group committed to your growth. Our work is technically demanding, mission-driven, and genuinely novel — there's nothing quite like it.
