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! The role - why it exists & why it's interesting 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.
