MMIC Design Engineer (Photonics)

Location: San Jose, California, United States

Company

hirify.global is a well-funded startup developing photonics infrastructure for AI supercomputing, including chip-to-chip optical interconnects and scalable photonic engines.

What you will do

• Design high-speed analog and MMIC circuits, including amplifiers, drivers, TIAs, and related building blocks operating from DC to tens of GHz.
• Own the design cycle from architecture and schematic design through simulation, layout guidance, tapeout, and silicon validation.
• Perform EM modelling, parasitic extraction, EM/IR analysis, reliability analysis, and physical verification using the specified EDA tools.
• Partner with layout engineers to optimize floorplans and minimize parasitic and electromagnetic effects.
• Develop Cadence SKILL, Perl, and Unix shell automation for design, simulation, and verification workflows.
• Collaborate with photonics, systems, and test teams to define specifications, support lab characterization, and correlate measurements with simulation.

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.
• 10+ years of EDA experience for senior roles.
• 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, electromagnetic 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
