Senior Mixed Signal ASIC Engineer - Boston, United States

Originally posted 14 October 2026 by the employer.

About the role

This role involves designing, taping out, and testing electronic ASICs that interface with Ayo’s photonic integrated circuits.

What you'll do

• Contribute to the architecture and specification of mixed-signal ASICs that control and interface with Ayo’s photonic integrated circuits.
• Perform schematic capture, layout, and verification for mixed-signal integrated circuits including digital-to-analog converters, analog-to-digital converters, transimpedance amplifiers, and transconductance amplifiers.
• Execute across the full design-to-test cycle: design, manufacture, bring-up, characterization, and validation.
• Support packaging and test requirements and flows for integrated circuits.
• Contribute to the bring-up and test of integrated circuits.
• Provide expertise and support to other Ayo team members.

What you'll need

• PhD in electrical engineering or equivalent industry experience.
• 5+ years of experience designing, simulating, and testing analog and mixed signal integrated circuits.
• Strong fundamentals in analog and mixed signal design, including ADC/DAC, amplifiers (TIA, OTA), and related circuit blocks.
• Commercial tape-outs preferred; strong hands-on foundry experience required.
• Proficiency with standard EDA tools such as Cadence or Synopsys.
• Demonstrated ability to take a chip from design through manufacture, test, and validation.

Nice to have

• Experience collaborating with integrated photonics teams.
• Experience with advanced packaging such as 2.5D / 3D integration.
