We’re looking for an experienced and curious Embedded Software Engineer to join our Product & Engineering team. In this role, you’ll take ownership of our firmware and  embedded systems — the core layer that powers Seroton’s unique relaxation experience.    

You’ll work closely with the Co-Founder and collaborate with Hardware Production, Mobile Engineering and Product Experience. Part of a small, ambitious startup, you’ll have real impact from day one — shaping not just how our hardware works, but how our users feel.  

If you enjoy building thoughtful products, working hands-on with hardware, and turning science-driven insights into real experiences, this role is for you.

Key Responsibilities 

• Own Seroton’s embedded firmware stack end-to-end, from prototyping to testing to release and iteration 
• Design and optimize embedded software for microcontroller-based systems with a focus on reliability and performance
• Develop and refine open- and closed-loop control systems for haptic and pneumatic actuation
• Build deep expertise in our SMA-based hardware and continuously improve system behavior
• Implement real-time sensor processing to enable interactive, user-facing experiences
• Option to contribute to future health-sensing algorithms for real-time mood and state tracking
