Senior Full Stack Engineer

Location: (in-person, Polanco)

Our Client is building the platform that moves money for our customers across Mexico, Peru, and Colombia, and we're expanding into the US. If you want to own real systems (not tickets), work directly with the CTO, and build something where correctness actually matters, this is for you.

What you'll do:

- Design, build, and ship features end to end across our services and customer-facing product
- Work across the transaction path: orders, quotes, payments, payouts, settlement
- Integrate with banking, payment rail, and custody partners, including their failure modes and edge cases
- Own the security and reliability of what you build, and deploy and operate it yourself
- Take part in on-call and help improve our incident response

What we're looking for:

- 5+ years building and operating production software with real ownership
- Strong TypeScript/Node.js and React




- Experience with Kubernetes and cloud infrastructure, deploying your own services
- Experience building APIs that other systems depend on (failure handling, retries, idempotency)
- Comfortable integrating third-party APIs that are unreliable or poorly documented
- Currently working at a recognized fintech, crypto exchange, payment processor, or neobank
- Professional English
- Based in Mexico City or willing to relocate (in-person, Polanco)

What you get:

- Competitive salary + medical insurance + stock options
- Direct access to the CTO and real ownership of what you build
- A small, senior team where nobody hands you tickets

If moving money at scale, ownership, and building something real excite you more than process, let's talk.
