About the role

Crebit Pay, Inc. is building the off-chain protocol powering FX hedges for fintechs, neobanks, and consumers. You will own the rate-lock state machine across quote, lock, settle, expire, and refund, and ship Go or Rust services with blazing performance. You will design public REST and webhook APIs for fintech customers, build the liquidity matching layer, and ensure p99 < 50ms quote generation under load in our SF office.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
