Job description
Senior Analog/Mixed Signal Engineer
Company: Extropic
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 Extropic
Extropic 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, Extropic 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
Extropic 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
Visa sponsorship record
No public sponsorship records foundWe didn't find H-1B, H-1B1, E-3 or green card (PERM) filings under the name See more jobs at Transparent Search Groupexternal in the Department of Labor and USCIS data. That doesn't mean the job can't be sponsored — the company may file under a different legal name, be new to sponsorship, or sponsor a visa that isn't in these datasets (for example H-2B or J-1).
Tip: ask the recruiter early, in writing, which visa they sponsor and whether they cover the legal and filing fees.
Which visas can work for this job
Occupation: Engineers, All Other (SOC 17-2199) — estimated from the job title.
- Mentioned in the listing
H-1B
- H-1B cap-exempt employer
Regular cap-subject employer — a new H-1B needs to win the lottery in March (unless you already hold cap-counted H-1B status).
- TN (citizens of Canada and Mexico)
This kind of role may fit the USMCA profession “Engineer” — it depends on the actual duties. No lottery, no cap; you need the matching degree or license.
- E-3 (Australia) and H-1B1 (Chile, Singapore)
Same degree requirement as H-1B, but no lottery and a separate quota that is rarely filled.
- O-1 (extraordinary ability)
For candidates with awards, publications, press, a high salary or critical roles at distinguished organizations. No cap, no lottery; the employer files a petition.
- STEM OPT extension (F-1 students)
Requires an E-Verify employer. We didn't find this company in the E-Verify list — ask HR.
Salary vs prevailing wage
Level IV (fully competent)Engineers, All Other · Boston-Cambridge-Newton, MA-NH. Annual prevailing wages set by the Department of Labor (OFLC).
| Level | Prevailing wage | H-1B lottery odds* |
|---|---|---|
| Level I | $92,976 | ~15% |
| Level II | $115,107 | ~31% |
| Level III | $137,259 | ~46% |
| Level IV | $159,390 | ~61% |
This job pays $160,000–$300,000 a year — that's Level IV (fully competent). In the wage-weighted H-1B lottery a Level IV registration gets 4 entries; estimated selection chance about 61% — better than average.
* Odds are DHS projections for the FY2027 wage-weighted lottery (actual results vary by year and employer). Since the FY2027 cap season the H-1B lottery is weighted by wage level: Level I = 1 entry, II = 2, III = 3, IV = 4. The level is set by the offered wage against the prevailing wage for the occupation and worksite. Separately, a $100,000 fee for new H-1B petitions for workers outside the US was announced in 2025; as of September 2026 a federal court ruling keeps it unenforceable while appeals continue — check the current status.
