Job description

You help other builders extend personal computing without having to understand every internal subsystem, which means making the safe path the easy one. If the secure way to do something is harder than the insecure way, developers will pick the second and be right to.

The work: Build SDKs, permission schemas, local development tools, examples and compatibility tests. Make capability boundaries explicit and error messages actionable. Support extension versioning, revocation and migration without exposing personal secrets to development tooling.

What good looks like: In your first 90 days, enable an outside developer to build and test one useful extension from documentation and examples.

Evidence we look for: Bring API design and software development experience with a strong interest in developer usability. Show how you reduced confusion, integration time or misuse.

Required:

• API design and software development with a real interest in developer usability
• You can show how you reduced confusion, integration time, or misuse
• You design so the safe path is the path of least resistance
• You write documentation as part of the work rather than after it

Nice to have:

• You have maintained a public SDK
• Developer research or usability testing on an API
• Multi-language client libraries

The exercise: Design an extension API that asks for the minimum necessary data and remains compatible when permissions become more precise.

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.
