Join RafX Technologies and take the technical lead in developing breakthrough radar- and AI-powered monitoring technology that transforms psychiatric and neurological care. This is a unique opportunity to shape core architecture, build a multidisciplinary team, and have real impact in a fast-moving health-tech startup.

⚡ ABOUT US

RafX Technologies is on a mission to transform care for psychiatric and neurological inpatients. Our AI- and radar-powered system, RafX SafeNight, uses concealed radar sensors to track patients 24/7, detecting health deterioration, agitation, and location — a true breakthrough in psychiatry, where patient monitoring today relies on nursing observations.

⚡ THE ROLE

We’re looking for a highly experienced and independent Lead Software Engineer to drive both the architectural vision and hands-on development of our platform. You should be comfortable taking technical ownership, solving complex problems, and driving development forward with minimal supervision.

You will build and lead a multidisciplinary team spanning full-stack development, signal processing, data analysis, UX/UI, and machine learning. This is a rare opportunity to join in the early startup phase and directly shape our technology roadmap.

• Experience with medical device software or other safety-critical systems (e.g., IEC 62304).

• Proficiency in Python, C++, and Linux.

• Experience in designing and deploying server-based solutions, maintaining databases, APIs, and communication protocols across devices, ideally in hospital, industrial, or embedded environments.

Technical Expertise

• Algorithm development and analysis of physiological sensor data or similar.

• Machine learning applied to biomedical or real-time monitoring use cases.

• Understanding of system architecture for distributed sensing or monitoring systems.

• Understanding of hardware–software integration and network solutions.

Preferred Experience

• Real-time monitoring or other safety-critical systems.

• Regulatory processes, quality systems, or clinical validation.

• Technical leadership or system architecture roles.

Personal Qualities

• Hands-on and proactive.

• Strong analytical and problem-solving mindset.

• Comfortable balancing leadership with development tasks.

• Motivated by impact in health tech and patient safety.

⚡ WHAT WE’RE LOOKING FOR

A self-driven engineer who thrives in a dynamic startup environment and isn’t afraid to wear multiple hats and grow with challenging tasks. If building something groundbreaking from scratch excites you, we’d love to hear from you. We welcome applicants from all backgrounds and nationalities.

⚡ WHAT WE OFFER

• A mission with real-world patient impact.

• Influence from day one in shaping core technology.

• Office at Startuplab, Oslo with a flexible hybrid work model — the role requires regular on-site work, so applicants should be based in the Oslo area.
