Senior Software Developer - Mission-Critical R&D (TS/SCI Required)

Tucson, AZ (Onsite)

$160,000 - $260,000 Base + Stock + Full Benefits + Paid Relocation

U.S. Citizenship + Active TS/SCI Clearance Required

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.

• 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

• 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

• 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:

• Experience in scientific or mission-critical systems
• Technical leadership + mentoring experience
• Passion for building enterprise-level internal platforms

• 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

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
