Senior Analog/Mixed Signal Engineer Company: Confidential — venture-backed technology company Location: Boston, MA (hybrid, 3 days in office) Compensation: $160,000 - $300,000 + competitive equity Employment Type: Full-time Visa Sponsorship: Visa transfers and new sponsorship (H-1B, TN) About the Company The client is building thermodynamic computing, a new compute paradigm that uses thermal noise in CMOS devices to perform probabilistic computation with radical power efficiency (potentially 10,000x savings over traditional approaches). Its founders, former Google Quantum Computing researchers, spent years fighting thermal noise before realizing they could harness it. Founded in 2022, the client has about 30 people, has taped out its third chip (Z1) and is defining the architecture for three more. It has raised a $14.1M seed. The Role The client is hiring a Senior Analog/Mixed Signal Engineer (3-5 years) to design and implement critical circuit building blocks for its thermodynamic computing chips. The team just taped out its third chip, a 250,000 p-bit fabric, and is defining three more. You will work across analog, mixed-signal and probabilistic circuit domains in a fast-moving startup where everyone gets hands-on. What You Will Do • Design analog and mixed-signal blocks: ADCs, PLLs, bandgaps, regulators, oscillators, high-speed dividers and SerDes. • Own block-level design across chips, from architecture and schematic through layout and tape-out verification (DRC, ERC, LVS). • Do hands-on layout and comprehensive Cadence simulation (PEX, Monte Carlo, corner analysis). • Support lab testing and validation of mixed-signal circuits. • Work across IC, systems, physics and algorithms teams to take thermodynamic sampling units from concept to silicon. What You Bring • 3-5 years of analog/mixed-signal IC design • Block-level design through tape-out • Cadence Virtuoso layout and simulation (PEX, Monte Carlo, corners) • CMOS process experience (FinFET, 28nm, 65nm) • Lab validation skills • Ability to work hybrid 3 days a week in Boston Tech Stack Cadence Virtuoso, CMOS (FinFET, 28nm, 65nm), PEX, Monte Carlo simulation, corner analysis, Python, C Before you apply: get a free recruiter-readiness score for your resume at CareerStanding — about a minute, no signup, and your resume stays in your browser.
