Principal RF and Microwave Engineer

Advanced Technology Development

ROLE OVERVIEW

Echodyne is seeking a Principal RF and Microwave Engineer to join the Advanced Technology Development team and lead forward-looking RF architecture, circuit development, rapid prototyping, and technology transition for future radar products.

You will join a high-performing, cross-disciplinary team where senior engineers have meaningful technical ownership, run fast experiments, and see their work move directly into future radar products. You will work on prototype development, including sensing, internal RF calibration, modular RF hardware, and higher-power subsystems.

The ideal candidate combines deep RF and microwave design experience with hands-on laboratory skill, sound judgment in uncertain development environments, and the ability to turn measured evidence into clear product decisions.

RESPONSIBILITIES

Lead RF and microwave architecture and development for advanced technology prototypes, critical technology investigations, and future Echodyne radar capabilities

Design, model, build, and characterize receivers, transmitter and receiver modules, frequency-conversion chains, synthesizers, filters, amplifiers, and related microwave circuits

Develop calibration architectures, measurement methods, and channel-correction approaches that improve radar performance and support efficient integration and test

Use analysis, simulation, rapid prototyping, and test to retire critical risk, establish design limits, and select credible paths to product adoption

Collaborate with antenna, analog and mixed-signal, digital, FPGA, PCB, systems, mechanical, manufacturing, and key stakeholders to deliver mission-critical solutions within challenging constraints

Establish characterized RF baselines, reusable design guidance, interface definitions, test methods, and transition packages for product-development teams

REQUIRED SKILLS / EXPERIENCE

Strong technical ownership of complex RF or microwave systems, subsystems, receiver chains, transmitter chains, or components

Strong knowledge of RF and digital electronics with hands-on experience across architecture, design, prototype bring-up, characterization, verification, and product transition

Experience with advanced RF technologies such as receivers, analog-to-digital converters, downconverters, mixers, frequency synthesizers, clock distribution, or high-power amplifiers

Experience defining RF requirements, interfaces, link or performance budgets, gain, noise figure, linearity, dynamic range, phase noise, stability, filtering, and impedance matching

Hands-on experience with network and spectrum analyzers, signal sources, oscilloscopes, noise and phase-noise measurements, automated test, and prototype troubleshooting

Experience planning and executing fast-cycle investigations, trade studies, experiments, and prototype iterations that connect models to measured results

Ability to communicate findings, risks, design limits, and recommendations clearly

Competence with MATLAB and RF or electromagnetic simulation tools such as Ansys Electronics Desktop, High Frequency Structure Simulator (HFSS), Keysight ADS, CST, or equivalent

DESIRED SKILLS / EXPERIENCE

(Looking for one or more as a complement to the core skills)

Experience developing RF or microwave hardware for radar, phased arrays, aerospace, defense, autonomous systems, or other high-reliability and mission-critical products

Experience with dual-monopulse architectures, sub-aperture processing, tiled apertures, internal calibration, or radar-level calibration

Experience evaluating emerging commercial technologies, suppliers, manufacturing processes, design for manufacturing constraints, or externally developed intellectual property

QUALIFICATION

BS in Electrical Engineering or a related technical field and at least 8 years of relevant RF and microwave hardware development experience, or equivalent experience

Eligibility to handle export-controlled technical data, including ITAR- and EAR-controlled information

Echodyne’s technology is export controlled by the U.S. Government and we must evaluate an applicant’s eligibility to handle export-controlled information or obtain required Government authorizations.  Therefore, we will ask you as part of the application process to identify whether you are a U.S. Citizen or green card holder, or have asylum/refugee status in the U.S.
