Job description

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

The role

This company builds a surgical intelligence platform that turns medical imaging into real-time 3D guidance, enabling complex, life-changing surgeries. They are rapidly scaling, pushing toward OEM-integrated hardware partnerships that bring their platform directly into the operating room.

You will own the entire Platform Software pillar: the Hub UI, the Surgical OS SDK, the edge deployment stack, and the cybersecurity posture required for hospital deployments. This is a rare seat to lead a growing team, delivering a commercial SDK that is a key unlock for the business, not just managing internal libraries or theoretical research.

The work

• Own the Hub UI, from clinician-facing interface to deployment at an anchor hospital by Q4 2026.
• Architect and run the edge stack on NVIDIA AGX-class hardware, maintaining sub-20ms latency with OTA updates and federated learning.
• Drive the platform's security posture, leading the path to SOC 2 Type II by Q4 2027.
• Deliver a v1 Surgical OS SDK, ready for OEM term sheets by Q1 2027 and signed contracts by Q2 2027.
• Scale and mentor a growing platform team (currently four engineers) to support expanding hospital deployments.

What You Bring

• You have shipped an SDK or partner-facing API that saw external integration, not just an internal library.
• You are hands-on with real-time, low-latency systems (C++, Rust, or similar) where sub-20ms targets are familiar territory.
• You have direct experience with edge or on-prem deployment, ideally on NVIDIA AGX-class hardware, including OTA updates and federated learning patterns.
• You have led a software engineering team of 4+ and can still dive into code or critical integration issues when needed.
• You understand the operational realities of SOC 2, HIPAA, or ISO 27001 compliance, even if you haven't personally held the certifications.
• You are based in or around London and comfortable with 3+ days a week in-person with a small, fast-moving team.
