Backend QA Engineer
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Backend QA Engineer based in United Kingdom.
Take ownership of quality across a high-traffic, backend-focused platform where reliability and precision are critical.
You’ll combine hands-on manual testing with automation to validate APIs, transaction lifecycles, data, and event-driven services.
The role gives you the opportunity to uncover edge cases and risks beyond what is explicitly defined in specifications.
You’ll work closely with engineers and other stakeholders to ensure robust releases and prevent critical issues from reaching production.
Your work will span REST and gRPC APIs, relational databases, message queues, and distributed backend services.
You’ll also contribute to automated regression coverage using Go and help continuously strengthen the testing approach.
Working fully remotely within a global team, you’ll have meaningful ownership in a fast-growing technology environment.
Accountabilities
- Analyze business requirements, functional specifications, and user stories to design comprehensive test cases, scenarios, and coverage strategies.
- Perform end-to-end testing of transaction lifecycles, including initiation, authorization, settlement, reconciliation, and related workflows.
- Proactively explore the platform to identify edge cases, unexpected behavior, risks, and gaps not covered by existing specifications.
- Validate data accuracy, integrity, and consistency across services using SQL queries against PostgreSQL and MySQL.
- Test REST and gRPC APIs using tools such as Postman, grpcurl, or equivalent solutions, validating requests, responses, error handling, and edge cases.
- Verify event-driven workflows across message brokers such as Kafka, RabbitMQ, and NATS, including retries, failures, ordering, and duplicate-message handling.
- Write, maintain, and extend automated regression tests in Go, collaborating with developers when additional test coverage or technical support is required.
- Log, prioritize, track, and manage defects in Jira, providing clear reproduction steps, payloads, logs, and relevant technical context.
- Execute regression testing following deployments and help ensure releases meet expected quality standards.
- Contribute to improving QA processes, automation coverage, and overall testing efficiency across the platform.
