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

Job Description

We are seeking a versatile and highly skilled Senior High‑Frequency Circuit Design Engineer to join our growing IC team. While our core team operates from Istanbul, Turkey, and Milan, Italy, we are open to hiring globally for this role, either as a remote position or as the foundation for a new site built around the right candidate.

As a key member of our design team, you will drive the full cycle of IC development.

Responsibilities

• Design 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.
• Drive transistor‑level circuit design, layout, and simulation with a specialized focus on bipolar (HBT) architectures at high and mm‑Wave frequencies.
• Apply a deep system‑level understanding of optical communication networks and complex RF applications to component design.
• Participate across the entire product lifecycle, including product definition, specification reviews, feasibility analysis, and architecture selection.
• Oversee top‑level physical verification and floor planning, as well as support post‑silicon validation and lab measurement activities.
• Utilize advanced CAD tools for rigorous design, modeling, and layout extraction.

Qualifications

• Electrical/Electronic Engineer with a BS degree and 5+ years of experience, an MS degree and 3+ years of experience, or a PhD degree and 2+ years of experience specifically in advanced high‑frequency technologies (e.g., SiGe BiCMOS, InP).
• Demonstrated, hands‑on experience in bipolar (HBT) circuit design at extremely high frequencies.
• Profound understanding of 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 and experience with 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.

Benefits

Competitive salary, a unique ESOP, and the opportunity to learn and grow exponentially. Work directly with the founders and contribute significantly to our shared mission.
