Sr. Software Engineer Security Clearance

Position: Sr. Software Engineer with Security Clearance
District Partners is supporting one of the most advanced, mission-driven defense tech companies in the country. They're considered the gold standard in modern national security engineering, and we're helping them expand a team that's building software with real-world impact. These Software Engineers join a flagship program that's been in the national spotlight for both its ambition and its operational importance.

The work blends autonomy, robotics, sensor fusion, high-performance distributed systems, and real-time mission software. You're not tweaking settings pages; the code you write affects real-world outcomes. This is production engineering at the edge. It's hands-on, hardware-adjacent, and deeply technical. You're building systems that coordinate sensors, process massive data streams, and make decisions across a distributed network where milliseconds matter. The engineering challenges here are the real deal:
* Real-time distributed systems where latency actually matters
* High-performance C++, RUST and Python driving autonomy, tracking, and decision engines
* Sensor fusion across radar, EO/IR, RF, and simulation inputs
* Software that spans hardware, cloud, and edge compute
* Robotics-adjacent work that requires clean abstractions and strong fundamentals
* A culture built around precision, pace, and engineers who think clearly under pressure They want depth, not "good enough." Strong CS fundamentals are non-negotiable, and the technical bar is high by design. What they look for:
* 7+ years building production-grade software
* Professional experience with languages such as Java, Python, C++, Rust, Go, and Java Script  
* Mastery of algorithms, data structures, concurrency, and networking
* Experience working in real-time, distributed, or safety-critical systems
* Comfort working close to hardware, sensors, and simulation environments
* A mindset made for solving difficult problems with clean, reliable code Location + Clearance:
* These roles are full-time onsite in Washington, DC.
* An active Top Secret clearance is required. No exceptions. Compensation:
* Compensation is designed to match the technical bar, with total comp reaching the 250k+ range through base salary, bonus, and equity.
* The client will fly candidates in for onsite interviews and offers relocation support. The process is selective but straightforward:
* Two video interviews focused on fundamentals, systems thinking, and collaborative problem-solving
* One onsite interview in DC
* A real-time coding assessment (video + in-person) that evaluates depth, clarity of thought, and the ability to write clean, correct code under realistic conditions This company invests heavily in evaluating talent because they want elite engineers-and they're building a team that reflects that. #CJ
