Protocol, Policy & Standards

Protocol Specification Engineers (PCHP, hu_ssh)

The written specification, the reference implementation, and the conformance suite that lets someone else implement it correctly without asking us a single question.

Apply for this roleAll open roles

A protocol only matters when somebody other than its author implements it. We run two: PCHP, the consent handshake behind every access to a person's data, which is live in the product today; and hu_ssh, which is a published design rather than shipped code, and we say so plainly. You do the unglamorous work that turns both into real specifications, reference implementations and conformance tests.

Kirkland GarageUAE Garage

In the office together five days a week, in one of our garages, and remote-friendly around your family, arranged one person at a time. We hire across the United States 🇺🇸, India 🇮🇳 and the UAE 🇦🇪.

Required

  • ▸You have written a specification precise enough that somebody else implemented it correctly
  • ▸Protocol or systems engineering, including the wire-level detail
  • ▸You build conformance tests, because a spec without them is a suggestion

  • ▸You have shipped an SDK others adopted

What winning looks like

  • ▸Independent implementations that pass conformance without our help
  • ▸Ambiguities found and closed before they reach an implementer
  • ▸Spec and shipped code stay aligned — drift caught in review, not in the field

What comes with the job

  • ▸Stock options for every full-time teammate, four-year vesting with a one-year cliff
  • ▸Annual performance bonus, or on-target earnings with uncapped commission for customer-facing roles
  • ▸Medical, dental and vision for you and your family, plus life and disability cover, on the highest plan tier available to us
  • ▸A 401(k) with company matching
  • ▸Pay reviewed every year and on promotion, benchmarked to your role and market
  • ▸A budget of AI tokens of your own
  • ▸Gym membership, and retailer discounts redeemed through our benefits app
  • ▸Remote-friendly around your family, arranged one person at a time
  • ▸$1,000 plus $10,000 in equity for a referral we hire who stays a year
