Job description

This is your opportunity to build real-world systems that directly impact national security-not theoretical work, not maintenance… true innovation deployed in the field. You'll join a highly elite, multidisciplinary R&D team of engineers, mathematicians, and scientists designing advanced geolocation and digital communications systems used in mission-critical environments. If you're driven by solving complex, unsolved problems and want to see your work actively used in real-world operations, this is where you belong. What Makes This Role Different

  • End-to-End Ownership - Design * Build * Test * Deploy * Operate
  • Deep Technical Work - Algorithms, architecture, and real-world data
  • True R&D Environment - Not product maintenance or incremental updates
  • Mission Impact - Your work directly supports national defense
  • Constant Innovation - Freedom to propose, experiment, and implement

What You'll Be Doing

  • Architect and develop high-performance, scalable software systems
  • Build and deploy advanced geolocation algorithms
  • Integrate complex systems with real-world operational environments
  • Collaborate across engineering, systems, and deployment teams
  • Mentor engineers and influence technical direction and innovation
  • Work across the full lifecycle: design, development, integration, testing, deployment, and O&M, Why Top Engineers Say Yes
  • Work on problems most engineers never get access to
  • Blend of research + hands-on engineering
  • Complex challenges that require real thinking-not repetitive coding
  • High compensation + full relocation support
  • Direct visibility of your work in real-world applications

Who This Role Is For This is for engineers who:

  • Get bored with routine development
  • Want to own and build systems from the ground up
  • Thrive in high-autonomy, high-expectation environments
  • Want their work to matter beyond code

Requirements

  • 15+ years in software engineering (senior/architect level)

  • Deep expertise in:

  • Data structures, algorithms, and system design

  • API development and distributed systems

  • Modern software engineering practices

  • Strong experience with:

  • Golang (highly preferred)

  • C++, Python (engineering/scientific environments)

  • Linux-based development

  • Proven ability to design scalable, high-performance architectures

  • Bachelor's in Computer Science/Engineering (MS/PhD preferred)

  • Active TS/SCI Clearance

  • U.S. Citizenship

Preferred (Stand-Out Candidates)

  • Cloud + DevOps: AWS, Docker, Kubernetes, CI/CD
  • JavaScript frameworks (React, Vue)
  • Experience in scientific or mission-critical systems
  • Technical leadership + mentoring experience
  • Passion for building enterprise-level internal platforms
