Principal Analog/Mixed-Signal Engineer

ABOUT THE ROLE Join an early-stage AI computing company developing chips that use CMOS thermal noise for probabilistic computing. As a Principal Analog/Mixed-Signal Engineer, you will lead key circuit and architecture work for upcoming chip designs, collaborating across engineering disciplines to bring new computing approaches to silicon. WHAT YOU'LL DO - Lead design of analog and mixed-signal blocks, including ADCs, PLLs, bandgaps, regulators, serializers and deserializers, oscillators, and dividers. - Own substantial portions of chip architecture and potentially serve as design lead for a planned chip. - Perform hands-on layout and design verification, including DRC, ERC, and LVS. - Work with IC, systems, physics, and algorithms teams to translate probabilistic computing concepts into silicon implementations. - Contribute to lab testing and validation of fabricated chips using signal generators, spectrum analyzers, and oscilloscopes. WHAT WE'RE LOOKING FOR - Six to 20 years of analog and mixed-signal IC design experience, including work on blocks such as PLLs, ADCs, or SerDes. - An MS or PhD in Electrical Engineering with a focus on circuits or IC design. - Experience completing multiple tape-outs, including in FinFET or 28nm/65nm processes. - Strong CMOS circuit design skills and experience across multiple circuit types and designs of meaningful complexity. - Proficiency with Cadence simulation, including parasitic extraction, Monte Carlo analysis, and process corners. - Hands-on layout experience and the flexibility to work beyond a narrow specialization in a startup environment. - Experience with tools and languages such as Python and C is relevant. COMPENSATION & BENEFITS Base salary is $200,000 to $325,000 annually. Visa sponsorship is available. LOCATION Hybrid, with three days per week on-site in Boston, Massachusetts, United States.
