About the role
Mission
QFEX is building a team of founding engineers who can design, code and own systems that will soon process billions of dollars in trading volume every single day. This is an incredible opportunity to work alongside a very well-backed team of builders from some of the biggest financial companies in the world (Citadel, Kraken, Tower Research Capital) and change the course of financial history.
What You’ll Do
Reliability & performance
Design fault-tolerant, low-latency, always-available services; write load tests and chaos suites; tune until p99 is boring.
Developer experience
Set up and maintain CI/CD, IaC, monitoring, and on-call processes that future teammates will thank you for.
Technical direction
Evaluate tools, set coding standards, and guide architectural decisions as we scale.
Culture & hiring
Share and receive new knowledge and experiences, set impeccable cultural standards, and help interview the next engineers.

- Deep Kubernetes or infrastructure-as-code experience.
- Cyber security and compliance know-how.
