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 Not Just Another Software Role.
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
- 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:
- 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
- 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
- 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
