About:
We’re Cryptio. We build infrastructure to bring financial integrity to the crypto economy. Our enterprise‑grade back‑office and data platform power mission‑critical accounting, reporting, and operational workflows for institutions, corporates, and crypto‑native organisations. We’re trusted by leaders like Circle, Societe Generale, Uniswap, Gemini, and the Government of El Salvador. We’ve raised $26m from top investors including Point Nine, 1kx, Tim Draper, and Ledger Cathay.
The opportunity:
We’re hiring a Backend Engineer to join our Integrations squad. You’ll be at the core of building and maintaining integrations between Cryptio’s SaaS platform and the crypto ecosystem’s richest set of third‑party APIs, supported by a modern engineering stack (TypeScript, Nest.js, Temporal, Kubernetes, AWS, Docker). This isn’t back‑office plumbing—your work will be mission‑critical for customers who rely on us for accurate back‑office operations and compliance. You’ll be challenged by rapidly changing APIs, dynamic data structures, and the need to deliver seamless, scalable connections to new exchanges, custodians, and trading systems.
Key technologies:
- TypeScript (key dependencies: Axios, Zod, Nest.js, Temporal)
- Redis
- S3
- Kubernetes on AWS, Docker, GitLab… (modern development stack)
What you’ll do:
- Write production‑grade TypeScript, bringing new integrations online and maintaining existing ones
- Own the end‑to‑end process: scope, document, and test your code for reliability
- Collaborate with Product and other engineers to make sure integrations meet customer needs
- Map messy, evolving data models into unified schemas
- Monitor health, resolve data inconsistencies, and proactively fix or improve integrations
- Contribute to architecture decisions to enhance scalability and reliability
We’re looking for someone who:
- Has 5+ years of software development experience and is confident working with TypeScript
- Has hands‑on experience integrating third‑party APIs (REST, GraphQL) and wrangling with OAuth/JWT/auth flows
- Brings clear communication—comfortable switching between technical and non‑technical audiences
- Thrives in fast‑paced, collaborative teams
- Has an analytical mindset, enjoys problem‑solving, and is excited by crypto and fintech
- Communicates fluently in English, written and spoken
Why you’ll love this role:
- You’ll be at the heart of the crypto/finance data revolution, shaping how large institutions navigate a rapidly evolving industry
- Work with cutting‑edge tech in a high‑trust, remote‑first environment where quality and ownership matter
- Work 100% remotely, with occasional travel to our hubs in Paris or London
- Lots of internal mobility opportunities
- 25 days annual leave, your birthday off, private medical, pension, home office budget and more!
Interview process:
- Talent Screen – 30 min
- Technical Interview – 1h
- Culture Interview – 30 min
- Offer
Ready to power mission‑critical integrations for the world’s leading crypto institutions? We’d love to hear from you.
