Senior Full Stack Software Engineer
About The Position
Quartermaster is seeking a Senior Full Stack Software Engineer to contribute to the development and scaling of their product, the Quartermaster platform. This operator-facing application is used by defense analysts, coast guard operators, and commercial fleet managers for real-time monitoring, querying, and action on maritime intelligence. The role involves end-to-end feature ownership, from backend geospatial fusion to React components, directly influencing customer interaction with global sensor data. The engineer should be comfortable working asynchronously within a distributed team.
Requirements
- 5+ years of professional full-stack software engineering experience.
- Strong command of React and modern JavaScript/TypeScript for building complex, stateful web applications.
- Solid backend chops in Spring Boot; experience designing and building REST APIs at scale.
- Hands-on experience with PostGIS document databases; able to design schemas and write performant queries.
- Working knowledge of AWS services (S3, Lambda, ECS/EKS, IoT Core, CloudWatch) and infrastructure-as-code tooling.
- Experience with microservices architecture, containerization (Kubernetes), and CI/CD pipelines.
- Ability to read and reason about complex data flows involving real-time streams, large media assets, and geospatial coordinates.
- Strong written and verbal communication skills.
Nice To Haves
- Experience with geospatial data, mapping libraries (Mapbox, Leaflet, Deck.gl), or AIS/vessel tracking systems.
- Familiarity with WebSockets or SSE for real-time UI updates.
- Background in defense, maritime, or government software with exposure to data security requirements.
- Experience integrating ML model outputs into user-facing product features.
Responsibilities
- 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.
- Build internal admin and fleet management tools that help our operations team configure, monitor, and support deployed SmartMast units.
- Collaborate closely with our design team to implement pixel-precise UI components for data-dense map views and sensor visualizations.
- Participate in on-call rotations and take ownership of service reliability and incident response for your services.
- Review code, mentor engineers, and raise the technical bar for the team.
