Senior High-Frequency Circuit Design Engineer (RF/Optical)

We are seeking a versatile and highly skilled Senior High‑Frequency Circuit Design Engineer to join our growing IC team.

This key role will drive the full cycle of IC development, responsible for:

• Designing cutting‑edge, high‑frequency RF and broadband circuits for optical communications and high‑speed data transmission, including TIAs, Modulator Drivers, VCOs, LNAs, and broadband amplifiers.
• Driving transistor‑level circuit design, layout, and simulation with a specialized focus on bipolar (HBT) architectures at high and mm‑Wave frequencies.
• Applying a deep system‑level understanding of optical communication networks and complex RF applications to component design.
• Participating across the entire product lifecycle, including product definition, specification reviews, feasibility analysis, and architecture selection.
• Overseeing top‑level physical verification and floor planning, supporting post‑silicon validation and lab measurement activities.
• Utilizing advanced CAD tools for rigorous design, modeling, and layout extraction.

Qualifications:

• Electrical/Electronic Engineer with BS degree and 5+ years’ experience, MS degree and 3+ years’ experience, or PhD degree and 2+ years’ experience in advanced high‑frequency technologies (e.g., SiGe BiCMOS, InP).
• Hands‑on experience in bipolar (HBT) circuit design at extremely high frequencies.
• Proven expertise in high‑speed/broadband RF and analog IC design methodologies for optical communication applications.
• Extensive experience with EDA tools such as Cadence, ADS, CST, EMPro, and EMX.
• Proficiency in top‑down CAD workflows and physical design considerations for high‑frequency routing.
• Knowledge of 3D EM modeling and simulation is highly preferred.
• Experience taking complex high‑frequency blocks from concept through tape‑out to successful silicon characterization.
• Excellent verbal and written communication skills.
• PhD degree is highly preferable.

We encourage applications from those with a knack for thinking outside the box, a commitment to collaborative problem‑solving, and a focus on quality results. If this sounds like you, apply today to join our dynamic team.
