Senior Medical Software Engineer  Berlin - 3 days pw in office up to 95k euro base  Hands-on engineering leadership  |  Recruiter brief  |  17 September 2026  The role  Aidvance is developing software for an FDA-regulated medical device that delivers depression treatment through spoken conversations in English. We are preparing a US pilot for 2027.  The priority before the pilot is a structured development process that meets applicable medical-device requirements. We need one hands-on senior engineer to establish that process and lead delivery across backend, mobile app and speech integrations, with support from our existing engineer.  What matters most  • Medical-software development. Strong preference for hands-on medical-device software experience: requirements, risk management, test evidence, controlled releases and technical documentation. Comparable regulated-software experience may transfer. • Engineering leadership. Can establish practical development processes, organize reviews and prioritize delivery. Engineering-management experience is a major plus; this remains a hands-on coding role. • Full-stack delivery. Built and maintained application and backend features, with automated tests, deployment and monitoring. Handles sensitive data responsibly and documents operation and recovery.  Where to look and secondary strengths  Start with medical-device software and digital-therapeutics teams. Healthcare voice/audio teams are also relevant when candidates bring regulated-development experience.  • Provider integration. Can integrate external speech services and test the complete product. Specialist audio experience is optional; a dedicated audio hire can be revisited after the pilot. • Conversation and audio evaluation is a plus. Experience with repeatable tests for conversation behavior, speech quality, response timing and interruptions, using commercial tools or custom setups.  Mobile expertise is secondary, but the role includes developing a new version of our mobile app following medical-device software development practices. Exact languages, speech vendors and specialist model training experience are not hiring filters.
