Senior Software Engineer in AI startup (5y+ experience)
JoltSynsor is a deep-tech spinout from Cambridge University, building the AI digital inspector to revolutionize infrastructure health monitoring. Our technology is solving a massive, global problem: the inefficiency and inaccuracy of manual inspections for critical infrastructure like bridges, tunnels, buildings and other large-scale assets.
Every year, trillions of dollars are spent on infrastructure maintenance globally, yet catastrophic failures still occur due to human limitations in inspection processes. Our mission is to eliminate these inefficiencies and risks by replacing manual inspections with an AI-powered solution that’s faster, safer, and more reliable.
Using our proprietary AI models and exclusive training data—developed through years of cutting‑edge research—we enable real‑time structural health monitoring at a fraction of the cost. This is a great opportunity to join a mission‑driven company tackling one of the most significant challenges in sustainability, safety, and efficiency.
The Opportunity
We are looking for a founding full‑stack Software Engineer to help us build this revolutionary platform from the ground up. It’s a great chance to be part of a game‑changing journey—to create technology that impacts everyone's daily life worldwide while shaping the future of a fast‑growing deep‑tech startup.
What You’ll Do
* Design and develop the core CMS and 3D rendering platform to power our AI‑based digital inspector.
* Work on cutting‑edge problems such as processing massive LiDAR datasets, implementing real‑time 3D rendering (Three.js), and integrating with proprietary AI models.
* Architect and implement systems across the stack, from backend (Node.js, Next.js) to frontend (ReactJS, TypeScript), and deploy on the cloud (Google Cloud).
* Collaborate directly with the founding team to define product features, technical strategy, and our roadmap for growth.
* Lay the technical foundation for scaling the product globally and help create a collaborative, high‑performing engineering culture.
What We’re Looking For
5+ years end to end product development working experience.
Technical Skills
* Knowledge of 3D rendering tools (Three.js) and familiarity with Azure for scalable application development.
* A solid understanding of system architecture, data schemas, and API design.
* Bonus: Experience with C++ or OpenGL for advanced point cloud 3D rendering.
Mindset & Motivation
* Passion for deep‑tech innovation and excitement to tackle big, meaningful problems.
* A desire to work on mission‑driven technology with real‑world impact.
* Entrepreneurial spirit with a willingness to take ownership and grow with the company.
* Focus on long‑term impact and growth rather than short‑term financial incentives.
