Load Test Engineer
Cyrex
About the Role
For more than a decade, Cyrex has secured and stress-tested the products of some of the world's most demanding technology companies, from global entertainment platforms to regulated financial and healthcare infrastructure. Load testing is one of the things we're best known for: studios and platform teams come to us ahead of a launch, major release, or marketing push — the point where years of work suddenly meets a very large number of simultaneous users, with no opportunity for a second attempt.
We do this using a load-testing platform we built ourselves, spanning a Go backend, two React frontends, and AWS infrastructure. Part of your role is keeping that platform healthy: maintenance, bug fixes, dependency and infrastructure upgrades, and targeted improvements when an engagement requires them.
The larger part of the role is the load testing itself: designing scenarios that accurately model how real users behave and implementing them in Python against whatever protocols the customer's system happens to use. Our load testing is expert-led — you'll work through iterations directly with the customer's engineering team and, as you grow into the role, lead those sessions.
Note: some test windows happen outside normal office hours.
