Principal Radar Systems Engineer

STR is focused on delivering National Defense capabilities by driving mission-focused strategies to develop advanced technology systems enabling enduring products and solutions focused on achieving the customer vision. Our programs deliver sustainable, reliable, and cost-efficient capabilities focused on end-customer needs that function in operationally relevant environments and timeframes. We consider the entire lifecycle of the solution, from conceptualization and architecting, through development to deployment, while leveraging novel technologies to deliver first-of-a-kind systems.

The Systems Development Division (SDD) within STR delivers technology advantage into users’ hands and is seeking a Principal Radar Systems Engineer to support/lead the architecting, design, development, and implementation of radar systems that meet challenging customer needs. You will collaborate with fellow researchers and engineers on multi-disciplinary teams to interpret and understand customer objectives and develop innovative solutions. You may direct and/or lead development efforts and junior engineers, as needed, in areas of focus including exploration and demonstration of Radar and EW/RF convergence. As a Systems Engineer, you will apply a broad perspective and understanding of the elements that comprise a complete, functioning radar system to architect solutions, be directly involved with implementing the solutions (hands‑on engineering), and guide teams spanning software, hardware, integration and test. You should have experience defining leading teams, architecting complete radar systems, and working across the Systems Engineering Lifecycle, with familiarity in Digital Engineering/MBSE.

Strong interpersonal, communication, technical, and peer‑leadership skills are required. Applicants are expected to be self‑motivated, detail oriented and have a demonstrated ability to effectively communicate with all levels of management and individual contributors on the program team through strong written and verbal communication skills. You will be joining a dynamic team working across multiple disciplines with opportunities to further expand your knowledge and grow your career.

What you will do:

• Researching, understanding, and leading new RF sensing implementations for advanced radar solutions. Identifying new technical approaches and working with program and technical leadership to implement these approaches.
• Decomposing customer needs/complex problems and developing system concepts and solutions.
• Effectively using tools to create, evaluate, and document solutions and clearly communicate the solution to the team, STR management, and customers, which may include generating system models in Cameo.
• Designing, directing, and when necessary, implementing cutting‑edge technology in multi‑function radar systems.
• Conducting performance analysis through simulations and real‑world testing to validate and optimize radar performance.
• Ensuring appropriate level of rigor is applied to achieve systems that meet customer needs.
• Collaborating with cross‑functional teams to define system requirements, specifications and architectures for radars, and ensure seamless integration and interoperability of the system.
• Development and specification of simulation tools to facilitate test and verification of radar software and hardware components.

Who you are:

• This position requires an Active Secret security clearance, and ability to obtain a Top Secret (TS) clearance with eligibility to support special access programs (SAP), for which U.S. citizenship is needed by U.S. Government.
• Expert understanding of and experience with entire radar systems and their principles of design, development, requirements verification, test planning, test execution, data analysis, and operations support.
• In‑depth knowledge of how to implement radar modes, including transmit and receive waveform generation and signal processing.
• Proficiency in radar simulation tools and MATLAB.
• Experience in preparing and delivering high‑level briefings to customers and senior management. Interacting with decision‑makers and customers to translate mission needs into an end‑to‑end solution.
• Familiarity with the execution of technical reviews (SRRs, PDRs, CDRs, TIMs).
• Demonstrated experience in leadership and delivery of advanced development projects.
• Minimum of 10 years work experience as a Radar Systems Engineer.
• Background should include a Bachelor’s degree and at least 10 years of applicable experience directly related to development and deployment of radar systems; Master’s degree and at least 8 years of applicable experience; or PhD and at least 5 years of applicable experience. Equivalent experience will be considered.

Even Better:

• 5+ years experience working with SysML models in Cameo (or similar tool).
• Experience working with software‑intensive systems and open architecture.
• Familiarity with programming languages (e.g. C, C++, Python).
