Nice to have: performance testing with k6, Gatling or JMeter; resilience or fault-injection testing; contract testing (e.g. Pact); multi-tenant systems; Go test automation; gaming, iGaming or payments background.
6-month engagement, likely to extend. Start in early December. The team is based in Eastern Europe and Azerbaijan, so an early start is needed.
