RF Application Engineer

Job Title

RF Application Engineer

Role Summary

Work on RF reference designs, evaluation hardware, and automated bench validation to support product design-in and customer deployments. Part of the applications/RF team partnering with sales and FAEs to resolve RF integration and field issues.

Experience Level

Mid-level — requires a minimum of 5+ years of R&D experience in RF circuit or wireless product design.

Responsibilities

Primary responsibilities cover reference design development, lab validation, customer support, and technical enablement.

• Create and validate RF reference and demo hardware; perform schematic/layout guidance and maintain reference design packages.
• Develop and improve automated RF bench tests (scripting, regression, reporting, repeatable flows) and run system validation.
• Bring up RF application hardware and correlate simulation with lab results.
• Partner with sales and FAEs to provide advanced technical support, influence RF architecture, and assist with PA/LNA and antenna integration and debug.
• Troubleshoot customer field issues to support successful deployments and rollouts.
• Produce application notes and deliver technical training to FAEs and sales teams.

Requirements

Must-have qualifications and skills required for the role.

• Minimum 5+ years of R&D experience in RF circuit or wireless product design.
• Strong written and verbal English; able to document and collaborate with global teams.

Nice-to-have skills and tools:

• Hands-on RF design, bring-up, and debug experience (PA/LNA, matching/filtering, FEM/switches, antenna integration) on reference/eval hardware.
• Simulation and correlation experience with ADS, HFSS, or equivalent; RF PCB layout experience (Altium, Protel, OrCAD) including stack-up, grounding, and controlled impedance.
• RF systems knowledge: link budgets, transceiver/FEM/antenna trade-offs, coexistence and deployment factors.
• Experience building RF bench automation and test scripts (Python, LabVIEW, or C/C++ with SCPI/VISA); regression tests, data capture, and reporting.
• Experience with spectrum analyzers, signal generators, VNAs, RF tuners, and noise-figure setups for calibration and automated measurements.
• MCU bring-up and embedded development experience (C/C++, Python) for evaluation boards and demos.

Education Requirements

Bachelor's degree or above in Electronics, Communications, Computer Science, Automation, or related disciplines.
