Looking for engineering problems that actually matter? Join Sand's Decision Intelligence Platform team and help build the semantic engines, data platforms, and AI-powered systems that enable governments and enterprises to make better operational decisions. This isn't feature development—it's designing the core technology behind critical infrastructure used by millions of people.
Sand Technologies is a global Physical AI company using data and AI to make critical industries work better. We partner with governments, cities and enterprises to improve how essential systems operate across healthcare, water, energy, telecommunications and infrastructure.
Our work delivers proven real-world impact. We have built AI systems that help manage London’s water supply, supported telecom network planning across hundreds of cities, and developed digital healthcare platforms serving tens of millions of people across Africa. From intelligent command centers to AI-powered infrastructure platforms, we help organizations sense, analyze and act in complex environments.
Our people are ambitious, curious and relentlessly practical. Our teams work alongside clients in the field, solving hard problems and deploying solutions that last. With colleagues across Africa, Europe, the UK and the US, we operate across the full stack - from research and engineering to deployment and capability building.
Our mission is simple: to harness AI to solve humanity’s most pressing challenges.
We're looking for a Staff / Principal Software Engineer to help build the next generation of Sand's Decision Intelligence Platform—the technology powering intelligent infrastructure for governments and enterprises across healthcare, water, telecommunications, energy, and other critical industries.
This isn't a traditional software engineering role. You'll architect and build the core capabilities that allow operators to understand complex systems, model how they behave, predict what happens next, and make better operational decisions in real time. From heterogeneous data integration and semantic modeling to distributed services, simulation engines, and AI-powered workflows, you'll own platform capabilities from concept through production.
Our platform is already solving real-world problems at national scale. Now we're looking for engineers who enjoy creating clarity from ambiguity, solving difficult systems problems, and building products where reliability matters.
Due to the highly collaborative and internationally distributed nature of our work, successful candidates must be comfortable operating in small teams while contributing to larger, globally coordinated efforts. A strong sense of ownership, self-motivation and discipline in maintaining clear and consistent communication through virtual collaboration tools and video conferencing is essential.
