Job description

About the Team:

The STR Sensors Division specializes in the development of advanced sensor systems, with a particular focus on airborne and surface-based radar, space-based sensing, electronic warfare, and underwater acoustics. This position is within the Space Missions and Sensing (SMS) Sector of the Sensors Division. In this sector, we develop and deliver technology to advance space-based sensing, space control, and counter-sensing missions.

The Role:

The SMS Sector is seeking a RF Engineer to support design, development, integration and test activities in a Research & Development environment. In this role, you will be an integral part of a team developing counter sensing systems for radar, electronic warfare and other applications. This position offers significant opportunities for career growth within a fast-paced and rapidly expanding company.

What you will do:

Work with small, multi-disciplinary teams to architect, design, implement, and test RF hardware systems enabling novel sensing, electronic warfare, and signal processing systems. The systems are predominantly fielded as deployable prototypes with the objective of transitioning to low-volume product systems
Collaborate with the team to quantify goals, system performance objectives, requirements, metrics, dependencies, and risks to guide your work
Design, simulate and test RF hardware systems, with an emphasis on RF system integration, test, and verification
Perform performance trade studies and analyses of proposed hardware architectures.  Conduct performance analysis through simulations and real-world testing to validate system performance.
Build, perform bench-top unit test, integrate, calibrate, and demonstrate/document system performance
Work with signal processing team on sensing system test concept and execution methods
Plan and implement over-the-air system tests and demonstrations, evaluate hardware and system readiness, , develop and evaluate performance metrics, verify requirements, manage system configuration and data, and write operational procedures, and performance reports
Review system effectiveness and identify opportunities to advance and/or mature subsystems and system capabilities
Prepare documentation including design specifications, drawings, test plans, and reports

Who you are:

This position requires the ability to obtain a Top Secret (TS) security clearance, for which U.S. citizenship is required by U.S. Government
BS in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline
5+ years experience working with RF components and subsystems, including T/R modules, rotary joints, pedestal, filters, radiating structures, isolators, amplifiers, cables, ADC/DAC, etc
Design experience in: RF systems, subsystems, and/or component analysis (frequency planning, link budget analysis, transceiver architectures, cascade analysis) 
Experienced in RF component/subsystem/system test and measurement equipment and techniques (anechoic chambers, oscilloscopes, vector network analyzers, spectrum analyzers, signal generators) 
Proficiency in MATLAB and/or Python and/or other higher-level languages 
Strong Mathematical, troubleshooting, written, and verbal communication skills

Even Better:

Experience integrating hardware and software, software development and or experience integrating FPGA’s
Active Secret or TS/SCI Clearance 
Advanced degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline  
Experience with:  
- RF systems engineering and technologies in one or more of the following areas:  sensing and electronic warfare applications including electronic attack, electronic protection, cognitive EW, radar, and advanced ESM techniques

Prior design experiences in one or more of the following: 
- Antennas 
- RF Printed Circuit Boards 
- RF Integrated Circuits 
- Transceiver building blocks (power amplifiers, low-noise amplifiers, oscillators, mixers, filters)

Join us and be part of a team that's making an impact at the forefront of technology and innovation.
