Apply now to be part of a team that values trust, excellence, and continuous learning.

• Lead the design and development of Silicon-based RFICs from initial concept through production release.
• Collaborate with module design teams and design management to define circuit architecture and detailed specifications.
• Manage technical decisions, track design progress, and resolve performance and implementation issues.
• Ensure alignment between simulation models, physical layout, and measured device performance.
• Coordinate regularly with remote design teams across time zones to maintain project momentum and technical consistency.

Minimum Qualifications

• BSEE with 5+ years of relevant industry experience, MSEE with 3+ years of experience, or PhD in Electrical Engineering or related field.
• For recent graduates, prior industry internship experience is required.

Technical Skills

• Strong understanding of transistor-level design for Silicon RFIC circuits, such LNAs (low-noise amplifiers), RF switches, directional couplers, and filters.
• Ability to optimize key RF performance metrics: insertion loss, bandwidth, linearity, power handling, noise figure, and mode switch timing.
• Familiarity with Silicon transistor device physics, layout techniques, and process characteristics.
• Solid foundation in RF and microwave engineering principles: small-signal and large-signal analysis, linearity, noise, Smith Charts, load-pull, and impedance matching.
• Ability to analyze and interpret circuit behavior in both time and frequency domains.

Tools & Lab Experience

• Proficiency in simulation tools such as Cadence Virtuoso and EMX. Experience with ADS and HFSS is a plus.
• Hands-on experience with RF and analog test equipment: spectrum analyzers, network analyzers, load-pull stations, RF probes, oscilloscopes, power meters, and noise figure meters.

Collaboration & Communication

• Strong communication skills with the ability to clearly present technical information.
• Capable of breaking down complex problems, setting priorities, and executing tasks on schedule.
• Willingness to work with remote teams across different time zones.

• Silicon chip tapeout experience from initial design through hardware realization.
• Familiarity with RFFE digital control schemes, register maps, and logic tables.
• Basic understanding of analog building blocks such as bandgaps, op-amps, regulators, precision current mirrors, and logic synthesis.
• Knowledge of layout techniques, device matching, ESD protection, and latch-up prevention.
