We build advanced software solutions for government and military missions, applying agile development and user-centered design to solve complex, mission-critical problems.

We are seeking a highly driven Principal RF Engineer to join our EW/SIGINT team supporting Defense and Intelligence Community missions. In this role, you will solve complex, mission-critical challenges and develop advanced RF collection capabilities that enable real-time situational awareness in dynamic operational environments.

You will support and sustain deployed operational systems, ensuring performance, reliability, and mission effectiveness in real-world conditions, while contributing to systems that discover, analyze, and exploit signals across full-spectrum operations—delivering precise, actionable intelligence when it matters most.

## WHAT YOU WILL BE DOING

- Support Army DEVCOM Quick Reaction Capability (QRC) initiatives onsite at APG
- Design and optimize RF systems, including antenna selection, placement, and integration
- Perform link budget analysis and signal propagation modeling to ensure system performance across operational environments
- Develop and prototype solutions in both Systems Integration Laboratory (SIL) and field environments
- Translate emerging mission requirements into technical concepts and rapid implementation plans
- Design, develop, and document RF components, subassemblies, and system-level architectures
- Review engineering designs, drawings, and technical documentation; provide actionable recommendations
- Resolve engineering change requests from customers, manufacturers, and suppliers
- Conduct reliability analysis and safety engineering assessments for RF systems
- Collaborate across multidisciplinary teams to deliver mission-ready capabilities under tight timelines

## WHAT YOU HAVE DONE

- 6+ years of hands-on experience designing, building, and testing RF signal collection systems
- 3+ years of experience in SIGINT or related fields (DoD, IC, or defense contractors)
- Strong understanding of RF fundamentals, including signal propagation, antenna theory, and link budget analysis
- Experience working in Agile environments, including use of tools such as Jira and Confluence
- Proficiency with Microsoft Office tools, including Project and Visio
- Demonstrated ability to build strong relationships with technical teams and mission stakeholders
- Proven track record of delivering solutions in fast-paced, mission-driven environments

## EVEN BETTER

- Experience with modeling and simulation tools such as MATLAB or STK
- Familiarity with requirements management tools such as DOORS Next Gen
- Experience supporting rapid prototyping or Quick Reaction Capability (QRC) programs
