• Design-Technology Co-Optimization (DTCO) - Partner with technology development teams to push transistor-level feasibility and achieve PPA (power, performance, area) breakthroughs in advanced nodes.
• Silicon Validation - Collaborate with test engineers to drive accurate silicon-to-simulation correlation, debugging, and optimization.
• Electromagnetic Simulation - Create and validate EM isolation methodologies for on-chip, package, and PCB integration.
• Mentorship - Initially operate as an independent contributor; gradually mentor junior designers and foster a culture of innovation.

Minimum Qualifications

• Master's or Ph.D. in Electrical/Computer Engineering or related field.
• 15+ years direct experience in mmW/RF/Analog circuit design for wireless/communication applications.
• Proven tape-out experience and direct involvement in delivering commercial designs.
• Demonstrated hands-on experience in the design of mixed-signal, analog, RF, or high-speed link circuits for wireless or wireline products.
• Strong understanding of RFIC fundamentals (noise, linearity, stability, mismatches, power efficiency, impairments).
• Expertise in tools: Cadence Virtuoso, Spectre RF, ADS, MATLAB, EMX, HFSS.
• Solid knowledge of semiconductor device physics and process technology.
• Strong analytical skills and the ability to translate system requirements into design specifications.
• Excellent communication skills and willingness to work across Taiwan and U.S. teams.

Preferred Qualifications

• Ph.D. with strong publication record (patents, journals, conferences).
• Familiarity with RF transceiver architectures and design trade-offs.
• Experience in mixed-signal verification methodologies.
• Proficiency in Python/Perl/Tcl for design automation.
• Prior exposure to AI/ML-based design optimization.
• Knowledge of reliability analysis (EM, IR-drop, thermal effects) and design for testability.
• Familiarity with semiconductor ecosystem.

Location

Primary location: San Diego, CA or Hsinchu, Taiwan.
Relocation support and visa sponsorship may be considered for exceptional candidates.
Some travel to Taiwan HQ expected.
