• This is a hands-on engineering role focused on building and operating production systems.
• An active Secret security clearance is required.

Qualifications

• 6+ years of relevant software engineering experience, with demonstrated full stack responsibilities in production environments.
• Demonstrated expertise in full stack development with modern JavaScript/TypeScript frameworks.
• Proven experience developing applications in React, including building and maintaining production React-based frontends.
• Strong frontend skills:
  • Experience with Angular (or comparable modern front-end framework) and TypeScript.
  • Hands-on experience building React applications (hooks, component composition, state management, routing).
  • Solid grasp of HTML, CSS, responsive design, and component-based UI patterns.
  • Experience with UI libraries such as PrimeNG or similar.
• Strong backend skills:
  • Node.js and Express.js for building RESTful APIs.
  • Experience designing and consuming OpenAPI/Swagger specifications.
  • Hands-on work with relational databases (PostgreSQL preferred), including SQL, indexing, and query optimization.
  • Experience deploying and operating services in Kubernetes and working with containerized applications (Docker, Helm, etc.).
  • Familiarity with job scheduling (cron-style schedulers) and event-driven or batch processing patterns.
  • Experience using AI-enabled development tools (e.g., GitHub Copilot, code assistants) to rapidly ship software.
  • Experience with testing tools across the stack (e.g., Jest, Vitest, Cypress, Playwright, or similar).
  • Familiarity with secure software development practices, including code scanning, dependency management, and security testing.
  • Comfort with CI/CD pipelines (GitHub Actions, GitLab CI, or similar) and Git-based workflows.
  • Comfortable with Agile/Lean, rapid delivery cycles, and direct user feedback loops.
• Active Secret security clearance required.

Requirements

• Hands-on work in secure government environments (DoD, IL5+, FedRAMP) or mission systems.
• Experience integrating or operating AWS services, including RDS, S3, and GuardDuty.
• Exposure to data engineering or analytics stacks such as Apache Spark, Apache Hudi, and Elasticsearch.
• Experience with API gateways (e.g., Kong) and service mesh / zero-trust patterns.
• Background in geospatial applications, mapping, or spatial analytics.
• Certifications such as Security+, AWS Developer/Architect, or Kubernetes-related certifications.
• Prior experience in startup or rapid-growth teams, or in building greenfield platforms within larger organizations.
