Our SmartMast system transforms commercial and civilian vessels into a persistent, distributed sensing network—combining HD video, AI, radar, RF sensing, and AIS to deliver real-time maritime domain awareness at global scale. With 600+ sensors deployed across 25+ countries and more than 400,000 vessels identified outside of AIS, we are setting a new standard for what ocean surveillance and safety can look like. We are a mission-driven, high-velocity team building dual-use technology for defense agencies, coast guards, and commercial maritime operators. If you want your code to run on vessels crossing every ocean on earth, this is the place.\n\nJob Description\nWe are looking for a 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 build and ship features end-to-end, from backend geospatial data layers to React components, translating complex real-time sensor data into clean, highly functional user experiences.\n\nKey Responsibilities\nBuild, test, and ship full-stack features across our React web portal and Spring Boot backend services.\nDevelop and maintain versioned RESTful APIs that surface sensor data, vessel telemetry, and AI detection outputs to end users.\nDeploy and maintain microservices running on AWS, ensuring service reliability and low latency under high-throughput data conditions.\nWrite and optimize PostGIS queries and data access patterns to support bulk artifact retrieval and map rendering across hundreds of vessels.\nBuild internal admin and fleet management tools that help our operations team configure, monitor, and support deployed SmartMast units.\nCollaborate closely with our design team to implement pixel-precise UI components for data-dense map views and sensor visualizations.\nQualifications (Preferred)\n2–4 years of professional full-stack software engineering experience.\nStrong command of React and modern JavaScript/TypeScript for building complex, stateful web applications.\nSolid backend experience in Spring Boot; experience designing and building robust REST APIs.\nHands-on experience with PostGIS or relational databases; able to write performant queries and understand data schemas.\nWorking knowledge of AWS services (S3, Lambda, ECS/EKS) and deploying applications in containerized environments (Kubernetes).\nFamiliarity with CI/CD pipelines and a strong understanding of version control (Git).\nAbility to read and reason about data flows involving real-time streams, media assets, and geospatial coordinates.\nStrong written and verbal communication skills; comfortable collaborating across teams and working asynchronously.\nBonus Points:\nExperience with geospatial data, mapping libraries (Mapbox, Leaflet, Deck.gl), or AIS/vessel tracking systems.\nFamiliarity with WebSockets or SSE for real-time UI updates.\nBackground in defense, maritime, or government software with exposure to data security requirements.\nExperience integrating ML model outputs into user-facing product features.\nWork Environment\nThis is a hybrid position, 3-days in office.\nFlexible working hours with occasional deadlines requiring high availability.\nOpportunity to work on innovative projects with a global impact.\nCompensation Range: $160K - $210K","company":"Quartermaster","rawCompany":"quartermaster","city":"Arlington","state":"VA","isRemote":false,"isActive":false,"createdAt":"2026-08-04T21:19:32.361Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1254.00","title":"Web Developers","slug":"web-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"}],"industries":[{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Full Stack Software Engineer","description":"About Us\nQuartermaster is building the world's most comprehensive maritime intelligence platform.
