Senior​/Software Engineer - Graphics

Who we are, what we do

Sensat is a geospatial AI business that powers advanced and highly functional digital twins for the world's most critical infrastructure projects. We partner with the world's largest construction, engineering and critical infrastructure companies, including National Grid, Network Rail, Heathrow and Severn Trent Water. We enable our customers to fight the costly and high-risk "Status Quo" of siloed data, people and processes.

Our AI-powered digital twins help teams digitally visualise, plan and manage projects, providing Project Confidence Through Clarity.

We are a high trust, high impact team, who offer purpose driven work. We operate with autonomy and flexibility in an agile, flat structure. We look for highly talented, adaptable and curious individuals who love solving meaningful problems and who share our resilient team spirit when facing challenges!

We are on track to more than double ARR in 2025, with a strong pipeline that positions us for another year of 100%+ ARR growth in 2026. Backed by over £25 million in funding from blue-chip investors like National Grid Partners and with imminent US market entry representing a significant value inflection point, this is an exciting time to join the Sensat team!

Visualisation is a core pilar of our digital twin platform, bringing together vast, messy, multi-format project data and turning it into something that makes immediate sense. You’ll be part of a team of innovators helping organisations see risks earlier, coordinate better, and make decisions with confidence.

We’re looking for someone who will take end-to-end ownership, pushing the boundaries of what’s achievable via a web browser — processing geospatial & CAD datasets; deciding on optimal mezzanine formats and storage; and rendering them quickly, accurately, and beautifully.

This is a high-trust, high-impact role. Sensat engineers solve problems rather than solely implement solutions. You’ll own the roadmap for this pillar, contribute across the platform to ensure our customers have a well rounded experience, and help the team continuously raise the bar.

If you’re after autonomy, innovating at the cutting edge, and literally seeing your work deliver real-world value, you’ll thrive here.

Please note we are considering candidates at both Senior and Staff level.

• Lead the design and development of functionality to serve large, complex 2D, 3D, and 4D datasets over the web.
• Keep on top of developments in graphics and geospatial processing tech, feed these into your roadmap, carry out spikes/research, and in turn influence the overall priorities of the platform.
• Act as a bridge between Sensat Labs (applied research) and the production platform team.
• Contribute to and improve the standards for software engineering, such as code quality, automated testing, documentation / knowledge sharing, and broader team processes.
• Contribute to maintaining the reliability of Sensat’s enterprise platform.

• Experience of rendering and optimising large scale 3D datasets from binary to server to web client.
• Significant expertise in 3D, WebGL/OpenGL, and a systems programming language (e.g. C, C++, Rust).
• Hands‑on experience with a GPU‑based rendering library such as three.js, luma.gl, deck.gl, Babylon.js, Unreal Engine, GLUT.
• You have a keen eye for detail, promote high standards, and have strong opinions but strike the right level of pragmatism.
• You’re a creative solver who learns fast, dynamically picking up the right new tech or habits that actually move the needle.
• You’ve actively mentored others on technical and operational matters, raising the bar and ensuring sustainable ways of working.
• 5+ years commercial development experience, demonstrating your ability to build, test, and ship reliable code.

• Side‑projects or participation in open source projects in a related field.
• Prior work in geospatial, web mapping or construction industries.
• Hands‑on experience with relational databases, Golang, cloud infrastructure, Angular 17+, Open Layers.
