DLS Engineering is seeking a Senior Software Engineer for a full-time position in support of the National Geospatial-Intelligence Agency (NGA) in St. Louis, Missouri. This is an on-site position. NGA is a unique combination of intelligence agency and combat support agency. It is the world leader in timely, relevant, accurate and actionable geospatial intelligence (GEOINT) .

This role requires strong full-stack Python experience, with a focus on API development, Kubernetes deployment, and modern Dev Ops practices to accelerate delivery. The Senior Software Engineer will work with an existing code base learning it quickly, manipulating it for adjacent use cases, and implementing new features that advance mission capabilities. A background in geospatial systems, imagery acquisition, and geometry is a significant plus.

This position supports an exciting modernization initiative providing enterprise architectural, engineering, operations and sustainment, modification, and testing of geospatial‑intelligence core services. This utilizes secure cloud environments, and a modern agile development methodology making data accessible, discoverable, and deliverable.

Anyone who sails a U.S. ship, flies a U.S. aircraft, makes national policy decisions, fights wars, locates targets, responds to natural disasters or navigates with a cellphone relies on NGA. This agency enables all the critical actions and shapes decisions that impact our world through geospatial intelligence. NGA is at the forefront of geospatial technology, using satellite systems and data analysis tools.

You can have a real impact on the mission while working with modern technology.
