Formal Methods and Verified Software Engineer

You make the most important guarantees precise enough to check, focusing formal reasoning on the boundaries where a mistake is expensive. The honest version of this role includes being clear about the gap between a proved model, the code generated from it, and the environment it actually runs in.

The work: Model authorization, recovery, concurrency and distributed task state. Use model checking, proof assistants or program analysis where they add practical assurance. Work with engineers to connect specifications to implementations and make assumptions visible.

What good looks like: In your first 90 days, formalize one critical protocol, identify counterexamples or prove scoped properties, and add implementation checks.

Evidence we look for: Bring formal-methods expertise with an interest in shipping systems. Explain the relationship between a proved model, generated code and the actual deployed environment.

Required:

• Formal-methods expertise with a genuine interest in shipping systems
• You can explain the relationship between a proved model, the generated code, and the deployed environment
• You choose where formality pays for itself rather than trying to verify everything
• You can work with engineers who do not share your background

Nice to have:

• TLA+, Coq, Lean, Dafny, or comparable in production use
• Verified cryptographic implementations
• You have found a real bug with a formal method

The exercise: Model revocation during failover and identify conditions under which a stale worker could still act.

How we work: We work together in the office, five days a week, and you can be based at any of our garages: Kirkland Garage (Kirkland, WA); UAE Garage (Dubai, Dubai). We hire across the United States, India and the UAE. We are remote-friendly around family: if you need to work from home some days to look after the people you love, we arrange that with you one person at a time, and we encourage people to use it rather than tough it out.

Pay: We publish what we pay. Indicative ranges by market and level are on our compensation page, and they are realistic going market rates rather than headline numbers. Wherever we hire we pay at least the local market rate, and for full-time roles our floor is a living wage, never the statutory minimum. Compensation is reviewed every year and on promotion.

Equity: Every full-time teammate gets stock options. Four-year vesting with a one-year cliff, sized to role, level and impact, and confirmed in writing at offer. High performers earn refresh grants.

Bonus and commission: An annual performance bonus tied to clear company and personal goals, indicatively 10 to 20 percent of base for non-sales roles. Customer-facing roles carry on-target earnings, typically a 50/50 split of base and variable, with uncapped commission and accelerators above quota.

Health and peace of mind: Medical, dental and vision for you and your family, plus life and disability cover. We have chosen the highest plan tier available to us rather than the cheapest one that clears the bar, because the point of this is that you never have to think about it. The specific plan numbers are confirmed in your offer letter.

401(k) with company matching: A 401(k) with a company match, so the years you spend here compound into something that is yours whatever happens next. The match formula is confirmed in your offer letter.

AI tokens: A budget of AI tokens of your own, because a company that says you should own your AI cannot be the company that rations it. Use them on the work and on whatever you are curious about.

Gym, and the everyday things: A gym membership, and a corporate benefits programme with its own app, where you redeem real discounts with a long list of retailers on the ordinary purchases of a life.

Family: We are remote-friendly around your family, arranged one person at a time, and we would rather you took it than toughed it out.

Referrals: Refer someone we hire full-time who stays a year and you get $1,000 plus $10,000 in referral stock-based equity, on top of your own package.
