Senior Full Stack Software Engineer
Quartermaster, Arlington, VA
The role
We are looking for a Senior Full Stack Software Engineer to help us build and scale the Quartermaster product—the operator-facing application used by defense analysts, coast guard operators, and commercial fleet managers to monitor, query, and act on maritime intelligence in real time. You will own features end-to-end, from backend geospatial fusion to React components, and your work will directly shape how our customers interact with data collected from sensors spanning the globe. You should be able to work asynchronously across a distributed team.
What you will do
- Design, build, and ship full-stack features across our React web portal and Spring backend services.
- Develop and maintain versioned RESTful APIs that surface sensor data, vessel telemetry, and AI detection outputs to end users.
- Architect and evolve our microservices layer running on AWS, ensuring reliability, scalability, and low latency under high-throughput data conditions.
- Optimize PostGIS queries and data access patterns to support bulk artifact retrieval, map rendering, and time-series analysis across hundreds of vessels.
