Software Engineer — Graphics & Platform

Sensat

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 more than doubled ARR in 2025 and are on track for another year of 100%+ ARR growth. We've built strong momentum with enterprise customers, secured further strategic investment from Mercia Ventures alongside existing investors including National Grid Partners, and are continuing to expand our presence in the US. It's an exciting time to join Sensat as we enter the next stage of our growth. THE ROLE — WHY IT EXISTS & WHY IT'S INTERESTING Visualisation is a core pillar of our digital twin platform. It's where vast, messy, multi-format project data gets turned into something that makes immediate sense to the engineers and project teams who depend on it. Done well, it's the difference between a project team catching a problem early and missing it entirely. We're looking for a software engineer who gets excited about graphics and geospatial technology, and is equally at home contributing across our wider platform. Graphics and data processing is where you'll go deepest, but this is a team that figures things out and we expect you to do the same wherever the work takes you. WHAT YOU'LL DO GRAPHICS & GEOSPATIAL * Build and improve pipelines to process, optimise, and serve large-scale geospatial and CAD datasets for the web. * Work with modern 3D data formats (glTF, USD, 3D-Tiles, point clouds) and understand the tradeoffs in how they're stored, streamed, and rendered. * Develop and iterate on rendering functionality using WebGL-based libraries, balancing visual quality, accuracy, and performance. * Stay close to developments in graphics and geospatial tech — feeding new approaches into your thinking and raising them with the team. PLATFORM & PRODUCT * Contribute across the SaaS platform — backend APIs (Golang), database work (Postgres), frontend features (Angular), and cloud infrastructure (AWS). * Contribute to platform reliability and engineering standards — code review, testing, documentation, and team processes. * Collaborate with product and customer-facing teams to ensure the platform delivers a well-rounded, high-quality experience. WHAT YOU'LL BRING MUST-HAVES * Hands-on experience with WebGL or a WebGL-based rendering library (three.js, luma.gl, deck.gl, Babylon.js, or similar). You've built or shipped something real with it. * Exposure to modern 3D asset formats such as glTF, USD, and 3DTiles. You understand what they're for and where they fit. * Comfortable working across the web stack. Graphics is a specialism here, not a silo. * Experience in a systems or compiled language (C, C++, Rust, or Go). You're not afraid of lower-level code when the problem calls for it. * Solid commercial software development. You’re comfortable building, testing, and shipping reliable code without heavy hand-holding. * When you hit something unfamiliar, you pull the thread. You ask early when stuck, but you don't wait to be unblocked. GOOD TO HAVE * Hands-on experience with cloud infrastructure or database design beyond the basics (AWS and Postgres are what we run). * Exposure to geospatial, GIS, or remote sensing concepts (CRS, raster/vector data, point clouds). Curiosity counts more than depth. * Prior work in construction, engineering, or infrastructure software. * Side-projects or open source contributions in graphics, geospatial, or a related area. Please note this role is hybrid with 1-2 days per week in the London office. WHAT WE'LL BRING 📈When Sensat succeeds, so will you, with significant equity share options 🏝️Take a break using your 30 days of annual leave (in addition to bank holidays) 🌎 A flexible working environment 🎓 Continue learning every day through your £500 personal development fund 🥳 Regular social events!
