NOXON is a Munich based MedTech startup founded in 2022 with the vision to transform muscle health on every skin. Guided by our purpose – moving what matters – we build technology that improves lives.
OCIAN is our medical wearable system that translates muscle signals into meaningful movement guidance.
At NOXON we believe in ownership. We believe in logic and strong partnerships over perceived limits. We believe that extraordinary results come from people who are willing to go the extra mile.
Job Description
We are hiring a full time Firmware Engineer to take ownership of the embedded firmware of our medical devices. You will take ownership of key components and build production-grade performance-critical firmware that is safe, robust, and efficient. You will work closely with hardware and software teams to design and refine firmware under technical and safety constraints in a regulated MedTech environment. Your work directly influences device reliability, signal quality, and safe behavior, shaping the performance and daily experience of people using our devices.
Your Main Tasks
- Take ownership of key firmware components and contribute to our performance-critical firmware architecture while developing production-grade firmware in C
- Build robust sensing pipelines from drivers to firmware application logic under safety and performance constraints
- Implement secure and reliable device communication and connectivity
- Establish automated testing and tooling to maintain firmware quality across the stack
- Debug and optimize at the hardware–firmware boundary, including performance/power tuning, understanding datasheets and schematics/PCB, and using oscilloscope/logic analyzer
Must-Have Qualifications
- Hands-on experience building safety- and performance-critical embedded firmware in C for deployed or production-intent systems (e.g. drivers, fault handling, timing constraints)
- Strong embedded fundamentals (e.g. interrupts, drivers, timing, power optimization, sensing pipelines, filtering)
- Experience implementing reliable device communication (e.g. reliable streaming, connection stability), ideally with security in mind
- Experience with structured engineering practices such as automated testing, CI, profiling, and hardware-level debugging
Nice-to-Have Qualifications
- Experience in embedded AI / on-device inference / edge-level data interpretation
- Experience with modern embedded frameworks
- Experience with wearables or body-signal-based systems
- Experience in a regulated MedTech environment
What you get
- Real ownership with direct product impact in a fast moving, high standards team
- Building technology that improves people’s muscle health
- Culture with an ambitious team where your contribution is visible and valued
- Trust-based working hours and offices where you can shape your own workspace
- Fast build–test–iterate cycles with direct access to lab equipment
- Steep learning curve and increasing responsibility as you demonstrate impact and ownership
What sets you apart
- You thrive in an environment where you take responsibility for quality and reliability of your outcomes
- You bring sustained drive, focus, and energy until meaningful outcomes are achieved
- You think in systems and consider failure modes, edge cases, and long-term maintainability
- You make good decisions with incomplete information and iterate fast
How to apply
Are we a match? If you bring high passion, talent, and the ambition to perform at a high-level, we will meet you at the extra mile. Please upload your CV and a description of at least one firmware project you played a key role in. The application process also includes a few short written questions.
