Job summary

Staffworx, a deep tech startup in Boston, MA, is hiring Principal and Senior IC designers to own and lead block-level analog/mixed-signal design for next-gen chips. The role involves hands-on layout, verification, and close collaboration with systems, physics and algorithms teams to bring probabilistic computing concepts into silicon.

With base salaries up to $325K plus equity, this ground-floor opportunity offers hybrid work with three days in the Boston office and relocation support.

Qualifications

• Strong analog IC design background with mixed-signal experience.
• Multiple tape-outs with transistor-to-system circuit analysis.
• Low-power design experience and PVT corner analysis.

Responsibilities

• Lead or own analog/mixed-signal block design (ADCs, DACs, PLLs, VCOs, LDOs, bandgaps, op-amps, comparators, high-speed SerDes).
• Own hands-on layout and verification (DRC/ERC/LVS).
• Support silicon bring-up and lab characterisation.
• Collaborate with systems, physics and algorithms teams to bring probabilistic computing concepts into silicon.

Job description

$160,000 to $325,000 base + equity

Staffworx are working with a well-funded, venture-backed deep tech startup based in Boston, MA. They're building a fundamentally new class of AI hardware, harnessing naturally occurring thermal noise in standard CMOS devices for ultra-low-power probabilistic computation, with the potential for order-of-magnitude power savings over conventional AI acceleration approaches.

Founded in 2022 by engineers with a background in advanced quantum computing research, the company has grown to around 30 people and has already taped out three chips. They're now defining the architecture for three further chips, so this hire gets genuine ground-floor influence over the product roadmap.

Two levels open on this search:

Principal (6+ years): potential design lead for one of three upcoming chips.

Senior (2 to 5 years): block-level design ownership.

Both will lead or contribute to custom analog and mixed-signal block design (ADCs, DACs, PLLs, VCOs, LDOs, bandgaps, op-amps, comparators, high-speed SerDes, oscillators and dividers), own hands-on layout and verification (DRC/ERC/LVS), support silicon bring-up and lab characterisation, and work closely with systems, physics and algorithms teams to bring novel probabilistic and stochastic computing concepts into silicon.

What good looks like:

• Strong analog IC design background, ideally with mixed-signal experience (SerDes, PLLs, VCOs, clock generation, dividers)
• Solid CMOS foundation; FinFET or advanced node (28nm and below) is a plus, not essential
• Multiple tape-outs, with genuine transistor-through-system circuit analysis (small signal, feedback, stability)
• Low-power design experience; noise, mismatch, Monte Carlo and PVT corner analysis
• Hands‑on custom layout experience, or willingness to pick it up in a startup environment
• Comfortable with broad-scope, unglamorous work typical of early‑stage hardware

Package: up to $325K base plus competitive equity.

Hybrid, 3 days per week in the Boston office. Relocation candidates considered.

Visa: role requires US export control authorisation (EAR/ITAR). Sponsorship and visa transfers (OPT, H1B transfer, new H1B, TN) supported for the right candidate previously, confirmed case by case.

This is a genuinely ground-floor opportunity to shape the architecture of a new computing paradigm in AI hardware, working across a small, highly technical team. Recruitment is currently a top priority for the hiring manager, so the process is moving quickly.
