Sr Software Developer
Henpen Corporation, Tucson, AZ, United States
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
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
What You Bring (Must-Have)
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
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
