Klaris AI is an AI-powered compliance automation platform designed specifically for MedTech companies. It streamlines regulatory documentation, helps medical devices gain approvals, pass audits, and scale by identifying regulatory gaps, providing remediation guidance, and catching contradictions. Klaris automates much of the manual compliance work, allowing engineers and medical device companies to focus more on innovation and product development. The platform is built to reduce the burden of compliance, speed up time to market, and facilitate integration with agile development processes in the MedTech industry.
What you will do
- Architect and build critical end-to-end components across the entire stack using Node.js, Next.js, TypeScript, and PostgreSQL while managing cloud infrastructure on AWS/GCP.
- Collaborate directly with the CTO to integrate custom AI models and LLM endpoints into a secure, production-ready platform that identifies regulatory gaps and remediations.
- Lead the development of intuitive user interfaces from Figma designs, ensuring high performance, responsiveness, and seamless state management for complex medical documentation workflows.
Who this is a fit for
- 4+ years of professional experience with the TypeScript/React/Node.js stack, demonstrating the ability to design and implement successful, standalone products or high-scale features.
- Proven "0-to-1" startup DNA with the high agency required to thrive in ambiguity, making independent architectural decisions without needing existing structure or oversight.
- Technical expertise in modern DevOps practices, including containerization (Docker/Kubernetes), CI/CD pipeline management, and secure database schema design for sensitive regulated data.
Why this role is remarkable
- Founding-level impact with significant equity and the autonomy to establish the technical foundations, engineering standards, and hiring culture of a mission-driven startup.
- Work on a non-wrapper AI product using proprietary datasets to solve a massive, high-stakes problem in a regulated industry with clear market pull and pilot traction.
- High-growth environment backed by strategic investors including an NHS-affiliated VC, Antler UK, and Vento Ventures, offering a direct path to shaping a generational MedTech company.
