Careers.
We spent a decade building a floor nobody could see. That tells you most of what you need to know about working here.
The work
Payment rails are a weekend. Proof is not. Most of what we do is unglamorous, correct, and only obviously valuable in hindsight — cryptographic plumbing, measurement, the parts of a protocol that have to be right the first time because they cannot be retrofitted.
If you want to ship something visible every fortnight, this will frustrate you. If you have ever been the person arguing that the boring layer needs to exist first, you already know what this is.
What we look for
Three things, and they are all the same thing.
You say what you do not know
Our own site publishes where we are behind and what is not shipped. That is not a marketing posture, it is how the people here already work, and someone who overstates internally will overstate externally.
You build things that verify without you
The test we apply to the product applies to the work: if you disappeared, would anyone be able to check that it was right? Good work here leaves evidence behind, not reassurance.
You are comfortable being early
This is a bet that machine commerce needs a real trust layer before anyone is loudly demanding one. Being right early feels identical to being wrong, for quite a while.
What we do not look for
Heroics, unsustainable hours, or anyone who treats an incident as a reputational problem rather than an engineering one.
Open roles
[CONFIRM: current openings, with a real salary range on each. If there are none, say so here plainly and leave the speculative route below open — an empty roles list is more honest than an evergreen listing nobody is hiring against.]
Nothing fits, and you still want in
Write to us anyway, but make it specific. Not a CV and a cover letter — one paragraph on something in our design you think is wrong, or something adjacent you have built that had to be correct the first time.
We read those. They are a better signal than an interview loop, and they take you ten minutes.
[CONFIRM: hiring process, how long each stage takes, whether take-home work is paid, and the legal entity and locations you can actually employ in.]
