Principal Validation Engineer

Principal Validation Engineer – Irvine, CA

Skyworks is an innovator of high-performance analog semiconductors powering the wireless networking revolution. This role plays a critical part in developing next-generation, highly integrated RF Front-End (RFFE) modules for mobile applications, translating customer specifications into product requirements across multi-chip module (MCM) and building block levels.

• Develop comprehensive test plans for RFFE modules and high-power amplifiers covering metrics such as P1dB, ACLR, harmonics, ruggedness, and efficiency.
• Execute validation using advanced RF test equipment (network analyzers, spectrum analyzers, power meters, load-pull systems).
• Analyze test data and provide actionable feedback to design teams.
• Validate RF amplifiers using GaN/GaAs technologies for LTE and 5G .
• Perform load‑pull analysis, impedance matching, and thermal optimization for maximum efficiency and ruggedness.
• Implement automated test scripts for efficient data collection and reporting.
• Ensure designs meet wireless standards (LTE, 5G ) and regulatory requirements for high‑power RF systems.
• Work closely with design, systems, and product engineering teams to accelerate development cycles and resolve technical challenges.

• BS degree and 12 years of overall experience.
• Preference for Master’s degree or PhD in Electrical Engineering or related field.

• Strong understanding of RF/microwave fundamentals and circuit theory.
• Solid knowledge of module building blocks:
  Power Amplifiers, LNAs, RF Switches, Couplers, Filters, and Multi‑chip Modules.
• Hands‑on experience with RF test equipment and load‑pull systems.

• Proficiency in RF simulation tools (ADS, Microwave Office) and scripting languages (MATLAB, Python, C/C++).

• Ability to interpret complex test data and optimize designs for performance and reliability.

• Familiarity with GaN/GaAs device technologies and thermal management strategies.
• Knowledge of wireless standards and compliance requirements.
• Experience with digital predistortion (DPD) techniques and high‑efficiency PA topologies (e.g., Doherty, Envelope Tracking).
• Familiarity with test tools such as GUTs and STC.

Base pay range: USD $129,400 – $247,800 per year, dependent on experience and location.

Benefits include healthcare, 401(k) plan with company match, employee stock purchase plan, paid time off (vacation, sick/wellness, parental leave), incentive plan, and additional awards.
