Senior high-frequency circuit design engineer (rf/optical)

Senior High-Frequency Circuit Design Engineer We are seeking a versatile and highly skilled Senior High‑Frequency Circuit Design Engineer to join our growing IC team. Location: Istanbul, Turkey and Milan, Italy, with remote options. This role may be the foundation for a new site built around the right candidate. Responsibilities Design cutting‑edge, high‑frequency RF and broadband circuits for optical communications and high‑speed data transmission (TIAs, Modulator Drivers, VCOs, LNAs, broadband amplifiers). Drive transistor‑level circuit design, layout, and simulation, focusing on bipolar (HBT) architectures at high and mm‑Wave frequencies. Apply deep system‑level understanding of optical communication networks and complex RF applications to component design. Participate across the entire product lifecycle: product definition, specification reviews, feasibility analysis, architecture selection. Oversee top‑level physical verification and floor planning, and 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 Ph D degree and 2+ years of experience specifically in advanced high‑frequency technologies (e.g., Si Ge Bi CMOS, In P). 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, EMX. Proficiency in top‑down CAD workflows and physical design considerations for high‑frequency routing. Knowledge of and experience with 3 D EM modeling and simulation is preferred. Experience taking complex high‑frequency blocks from concept through tape‑out to successful silicon characterization. Excellent verbal and written communication skills. A Ph D degree is highly preferable. Benefits Competitive salary, unique ESOP, opportunity to work directly with founders, and remote options. #J-18808-Ljbffr
