The engineer will work with an existing code baseโ€”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. Candidates must be passionate about modern architectures, able to adapt quickly to existing systems, and excited to tackle challenging technical problems for our mission users.

Required Skills

  • Strong full-stack Python development experience

  • Experience building and maintaining APIs (ex. FastAPI)

  • Experience with Kubernetes and DevOps practices to support rapid deployment and sustainment.

  • Proven ability to work with pre-existing code bases, understand them quickly, and adapt functionality for new use cases.

  • Experience with web services architecture, design, and development.

  • Background working in secure cloud environments (e.g., AWS GovCloud, C2S).

Nice to Have

  • Understanding of geospatial systems, including imagery acquisition, geometry, and related workflows.

  • Familiarity with geospatial data tools and libraries (e.g., PostGIS, ArcGIS, GDAL).

  • Prior exposure to DoD/IC mission applications.
