As a Software Engineer at S5 Analytics, you will play a key role in building and enhancing mission-critical geospatial applications that support the distribution of intelligence to end users. Working within an Agile Scrum team, you'll contribute across the full development lifecycle-translating system requirements into scalable solutions, developing both backend services (Java/Spring Boot) and modern frontend interfaces (Angular/TypeScript), and supporting ongoing system performance and reliability. You'll work across the application stack, helping to ensure efficient data flow from user interface through services and into underlying data platforms, including troubleshooting and optimizing data retrieval and system behavior. This role requires a proactive, solutions-oriented engineer who can clearly communicate technical concepts, take ownership of their work, and contribute meaningfully to a collaborative team environment supporting critical national security missions.

This is a full-time, on-site role with a 9/80 schedule.

• Familiarity with modern software development practices (Agile/Scrum, Jira, Confluence)
• Experience with containerization and/or cloud-native tooling (Docker, Kubernetes)
• Working knowledge of SQL databases and general data modeling concepts
• Ability to troubleshoot issues across the stack (e.g., debugging data flow, resolving data retrieval issues)
• Understanding of end-to-end web application data flow (UI → backend services → database)
• Experience with version control and CI/CD pipelines (Git, Jenkins, or similar)
• Strong communication skills, including the ability to explain technical concepts and decisions clearly
• Active Top Secret clearance with SCI Access and U.S. Citizenship
• Bachelor's degree in a STEM (Science, Technology, Engineering, or Mathematics) field is required

Nice to have Qualifications:

• Experience with Elasticsearch or similar search/data platforms (indexing, querying, troubleshooting)
• Familiarity with microservices architectures
• Experience with frontend + backend (full-stack exposure)
• Background supporting geospatial, analytics, or data-intensive systems
