Principal Software Engineer
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.

About the role
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.
