Software Engineer- System Integration; Mid to Senior Security Clearance

Position: Software Engineer- System Integration (Mid to Senior) with Security Clearance
About Geon Geon Technologies is a rapidly growing small business that provides signal processing and sensor system integration services to the United States Government (USG) and the industry base that supports them. Geon seeks to be known for "signals, sensors, and systems." Geon has expertise in the science and development of signal processing techniques and algorithm solutions for multi-INT applications.

The signal processing and hardware focused sectors of Geon are supported by the work Geon conducts with open architectures, open frameworks, and open systems that facilitate the rapid development, integration, and deployment of techniques and capabilities to operational contexts. About the Role Geon Technologies is building out a small, focused team roughly four to five engineers to deliver a 5G detect, decide, defeat pipeline for a defense customer.

Most of the building blocks already exist across our portfolio; the hard work is bringing them together into a single, coherent, operational system and getting it onto platforms where it will actually be used. We're looking for a mid-to-senior software engineer who can move fluidly between writing C++,integrating other people's components, debugging across process and machine boundaries, and getting hands-on with RF hardware in the lab.

Experience integrating software onto SOSA/MOSA-aligned platforms of record is a strong plus. If you're energized by the idea of owning a meaningful slice of a real end-to-end system - rather than one tiny corner of a giant codebase - this is that role. What You'll Do
* Integrate existing DSP, networking, and application components into a working 5G detect /decide / defeat pipeline.
* Write and maintain production C++ that glues the pieces together and fills in the gaps.
* Debug and harden the system across process, machine, and network boundaries - gRPC, REST, multicast UDP, VITA 49 streaming, and similar interfaces.
* Support real-world SDR data collects: set up radios, run captures, analyze results, and drive fixes back into the codebase.
* Deploy and integrate the pipeline onto operational platforms, including embedded and rugged compute environments.
* Contribute to CI/CD and containerized deployment workflows (Docker, Kubernetes) as the system matures.
* Work directly with RF engineers, systems engineers, and program leadership - and with the government customer - to turn requirements into a fielded capability.

Required Qualifications
* Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field - or equivalent professional experience.
* 7-10 years of professional software engineering experience.
* Strong modern C++ (C++17 or later), including templates, concurrency, and performance-minded design.
* Comfortable developing and debugging on Linux.
* Demonstrated experience integrating software with real systems - not just shipping libraries, but making them run reliably alongside other people's code on real hardware.
* Willingness to work with hardware: SDRs, RF front-ends, signal generators, spectrum analyzers, oscilloscopes. You don't need to be an RF engineer, but you shouldn't flinch at a lab bench.
* U.S. Citizenship and willingness/eligibility to obtain and maintain a TS/SCI clearance.
* Ability to work primarily onsite on Columbia, MD with limited work from home as tasking allows
* Ability to occasionally travel to customer locations when needed Nice to Have
* DSP fundamentals - sampling, filtering, FFTs, mixing, basic modulation/demodulation
-and the interest to grow in this area.
* Performance optimization experience with SIMD / Intel intrinsics (SSE, AVX, AVX-512).
* Experience with Kubernetes and Docker in production or lab deployments.
* Familiarity with SDR platforms such as Ettus USRP, Epiq Sidekiq, or similar.
* Familiarity with SOSA and MOSA standards, and experience integrating software onto platform-of-record systems built around them.
* Exposure to cellular, 5G, SIGINT, or EW domains.
* Experience with VITA 49, SigMF, or comparable RF data formats.
* Python for tooling, analysis, or prototyping.
* Git Lab CI/CD, container registries, and CMake-based build systems.
* Active DoD security clearance. What You'll Get
* A seat on a small team where your work is visible end-to-end and ships on a real schedule.
* Meaningful, fast-moving work with a direct line from prototype to operational use.
* Access to real RF hardware and live-air test opportunities. Visit  to learn more about us! Benefits:
