Senior Analog/Mixed Signal Engineer

ABOUT THE ROLE Join a hardware team developing a new class of computing chips based on thermodynamic computing. You will design circuits across analog, mixed-signal, and probabilistic domains, helping take new chip architectures from concept through silicon. WHAT YOU'LL DO - Design analog and mixed-signal circuit blocks, including ADCs, PLLs, band gaps, regulators, oscillators, high-speed dividers, and SerDes. - Own block-level design across multiple chips, from architecture and schematic development through layout and tape-out verification, including DRC, ERC, and LVS. - Perform hands-on layout and Cadence simulations, including parasitic extraction, Monte Carlo, and corner analysis. - Support lab testing and validation with signal generators, spectrum analyzers, and oscilloscopes. - Collaborate with IC, systems, physics, and algorithms teams to bring sampling circuits from concept to silicon. WHAT WE'RE LOOKING FOR - Three to six years of CMOS analog and mixed-signal IC design experience, with an MS or PhD in Electrical Engineering focused on analog or mixed-signal design. - Multiple tape-outs, ideally using FinFET or 28 nm or 65 nm processes. - Experience designing one or more of ADCs, PLLs, oscillators, regulators, or high-speed SerDes, along with exposure to a range of circuit types. - Mixed-signal design experience, hands-on layout skills, and proficiency with Cadence. Python and C/C++ are relevant tools. - Ability to perform small-signal and feedback analysis, including closed-loop gain, loading effects, and Miller analysis. - A practical, hands-on approach and willingness to work across circuit areas beyond your primary specialty. COMPENSATION & BENEFITS Base salary range: $160,000 to $300,000 annually. Visa sponsorship is available. LOCATION Hybrid, with three days per week on-site in Boston, Massachusetts, United States.
