MMIC Design Engineer

The role

This person will design and develop high-speed analog and monolithic microwave integrated circuits for photonic interconnects. The role covers the full design cycle from concept through tape out and silicon validation.

What you will do

• Design and develop high-speed analog and MMIC circuits including amplifiers, drivers, and TIAs.
• Own the full design cycle from architecture and schematic design through simulation, layout guidance, tape out, and silicon validation.
• Perform EM modelling and simulation of passives, interconnects, and critical structures using Cadence EMX.
• Run parasitic extraction, EM/IR, and reliability analysis using Quantus QRC and Voltus-XFi.
• Simulate and verify designs using Spectre and Synopsys HSPICE/PrimeSim.
• Partner with layout engineers to optimize floorplans and complete physical verification with Calibre.
• Develop automation and scripts in Cadence SKILL, Perl, and Unix shell.
• Collaborate with photonics, systems, and test teams to define specifications and support lab characterization.

Required qualifications

• MS or PhD in Electrical Engineering or a related field.
• 5+ years (MS) or 3+ years (PhD) of analog IC design experience, with 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 have

• 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 modelling.
• Experience working with engineering teams across multiple international locations.

Benefits

• Competitive salary commensurate with experience
• Comprehensive benefits package including health insurance
• Professional development opportunities and certification support
• Access to cutting-edge technology and cloud platforms
• Collaborative work environment with cross-functional teams
