Principal Analog/Mixed Signal Engineer

About the Role

This is a principal-level IC design role at the heart of a novel thermodynamic computing platform that uses thermal noise in CMOS to perform probabilistic sampling, targeting dramatic power efficiency gains for AI acceleration and edge computing. You will join a small, senior engineering team that has already completed multiple chip tape-outs and is now defining the architecture for its next generation of silicon. The work spans the full analog/mixed-signal design cycle, from architecture through lab validation.

What You'll Do

• Lead the design of analog and mixed-signal blocks including ADCs, PLLs, bandgaps, regulators, high-speed SerDes, oscillators, and dividers for upcoming tape-outs.

• Own large portions of chip architecture and serve as design lead for one of several planned chips.

• Perform hands-on layout work and design verification including DRC, ERC, and LVS.

• Collaborate with IC, systems, physics, and algorithms teams to translate probabilistic computing concepts into silicon.

• Support lab testing and validation of fabricated chips using signal generators, spectrum analyzers, and oscilloscopes.

What We're Looking For

• 6 or more years of experience in CMOS analog and mixed-signal circuit design.

• Hands-on design experience with mixed-signal blocks such as PLLs, SerDes, ADCs, or oscillators.

• Multiple completed tape-outs, ideally in FinFET or advanced nodes such as 28nm or 65nm.

• Proficiency with Cadence simulation flows including PEX, Monte-Carlo, and corners analysis.

• Layout experience beyond review, comfortable getting hands-on in a lean team environment.

• MS or PhD in Electrical Engineering with a focus on circuits or IC design.

• Familiarity with Python or C is a plus for scripting and verification support.
