MMIC Design Engineer

Lumilens•San Jose, CA

About The Position

Lumilens is seeking an experienced MMIC Design Engineer to design and develop high-speed analog and monolithic microwave integrated circuits for next-generation photonic interconnects. The engineer will own circuit design from concept through tapeout and silicon validation, covering DC-to-tens-of-GHz performance, EM modeling, parasitic extraction, and signoff on advanced process nodes. The role works closely with photonics, layout, CAD, and test teams to deliver robust, high-performance silicon across multiple programs.

Requirements

MS or PhD in Electrical Engineering or a related field.
5+ years of analog IC design experience with an MS, or 3+ years with a PhD, including high-speed or advanced process node experience.
Proficiency in Cadence EMX, Virtuoso Studio, Spectre, Quantus QRC, Voltus-XFi/EMIR, Calibre, and Synopsys HSPICE/PrimeSim.
Strong understanding of DC-to-tens-of-GHz analog design, device physics, parasitics, EM effects, and high-frequency analysis.
Skill in Cadence SKILL, Perl, and Unix shell scripting for automation.
Excellent communication, teamwork, problem-solving, and multitasking abilities.

Nice To Haves

10+ years of EDA experience for senior roles.
Experience designing circuits for optical interconnects, such as laser and modulator drivers or TIAs.
Tapeout experience in advanced CMOS, SiGe BiCMOS, or similar high-frequency process technologies.
Hands-on lab experience with high-frequency measurement equipment such as VNAs, sampling oscilloscopes, and BERTs.
Familiarity with high-speed package and board co-design, including signal integrity and transmission line modeling.
Experience working with engineering teams across multiple international locations.

Responsibilities

Design and develop high-speed analog and MMIC circuits, including amplifiers, drivers, TIAs, and related building blocks operating from DC to tens of GHz.
Own the full design cycle, from architecture and schematic design through simulation, layout guidance, tapeout, and silicon validation.
Perform EM modeling and simulation of passives, interconnects, and critical structures using Cadence EMX and related tools.
Run parasitic extraction, EM/IR, and reliability analysis using Quantus QRC and Voltus-XFi to ensure design robustness and signoff readiness.
Simulate and verify designs using Spectre and Synopsys HSPICE/PrimeSim across process, voltage, and temperature corners.
Partner with layout engineers to optimize floorplans, minimize parasitic and EM effects, and complete physical verification with Calibre.
Develop automation and scripts in Cadence SKILL, Perl, and Unix shell to streamline design, simulation, and verification workflows.
Collaborate with photonics, systems, and test teams to define specifications, support lab characterization, and correlate measurements to simulation.
