PREFERRED QUALIFICATIONS THAT SET YOU APART: Experience owning hardware development from concept through production ramp, including DFM, DFT, NPI, and supplier engagement. Experience with product concept development, systems engineering, requirements management, risk management, and project planning in complex product development environments Experience developing formal verification plans, validation procedures, and compliance evidence for production release Experience designing and debugging low-noise, high-precision measurement systems where accuracy, stability, drift, and calibration performance are critical Deep expertise performing SI/PI analysis and optimization of complex high-speed, mixed-signal, or RF systems. Experience researching, prototyping, and de-risking emerging technologies or new architectures. Familiarity with regulatory, safety, EMC, and material compliance constraints such as IEEE, MIL, RoHS, or REACH. Experience designing, simulating, verifying, and releasing RF circuits or subsystems using industry-standard tools. Experience developing hardware for automated test and measurement, instrumentation, aerospace, defense, communications, semiconductor, or other high-performance electronic systems. Proficiency with RF instrumentation (VNA, spectrum analyzers, vector signal generators) Programming or automation experience with Python, C, MATLAB, LabVIEW, Verilog, or VHDL Demonstrated ability to mentor junior team members in application of analog hardware design best practices Experience providing technical leadership across geographically distributed or cross-functional engineering teams.
