Lead RF Systems Integration Engineer

About the Team The Sensors Division at STR focuses on technology development for advanced sensor systems and platforms in support of national security requirements. Our particular focus areas include airborne/spaceborne/surface-based radar, electronic warfare, underwater acoustics, hyperspectral imaging, and EO/IR sensing. To support these missions, the Division’s efforts span multiple technical areas, including RF analog/digital hardware, acoustic hardware, signal processing algorithms, machine learning algorithms, systems analysis, and real-time embedded processor implementation. The Algorithms, Processing and Experimentation (APEX) Group specializes in development of RF/radar modes, skills and applications, with particular emphasis on advanced signal processing chains and associated algorithm research. We mature these technologies with the objective of implementation, integration, and eventual utility in RF-based systems, typically tailoring our work for highly specific Defense (e.g., Air Force, Space Force, Navy, DARPA, etc.) and Intelligence Community needs. The Role: We are seeking an experienced RF Systems Integration Engineer to lead RF test, measurement, and system integration activities in support of integrating a new operational mode onto an externally developed radar system. This role requires deep hands-on expertise in RF and radar systems, combined with the ability to understand, influence, and integrate with a complex radar platform owned and developed by another organization. You will serve as the technical authority for RF systems integration owning the end-to-end understanding of the radar, defining integration requirements, leading RF characterization and testing, and designing the technical approach required to successfully implement and validate our mode on the partner radar system. What you will do: Lead RF testing, measurement, and characterization efforts across lab, integration, and system-level environments Develop a deep technical understanding of a third-party radar system, including RF architecture, signal chains, modes, interfaces, and operational constraints Define and own the RF systems integration approach for implementing a new mode on an externally developed radar Translate system-level objectives into clear RF, interface, and integration requirements Design and validate integration strategies, including RF interfaces, timing, control, and signal processing impacts Collaborate closely with the external radar developer to resolve RF, system, and integration challenges Lead integration test planning, execution, and analysis, including defining success criteria and validation methods Identify risks and tradeoffs related to RF performance, integration complexity, and system compatibility Serve as the technical lead and escalation point for RF systems integration issues Communicate findings and recommendations to internal leadership and cross-organizational stakeholders Who you are: …
