QA engineer (auto) in fintech

Hyperlayer is the intelligent banking platform built for the agentic economy: the financial control layer that sits above banks' existing cores, enabling next-generation Smart Accounts, without ripping anything out. From a single integration, we give financial institutions a secure rules and orchestration engine that lets them design, launch and scale hyper-personalised products in weeks while preserving stability, compliance and control. And there's nothing like us anywhere in the world.

• Review acceptance criteria before work starts, covering edge cases, error paths and non-functional expectations.
• Turn complex orchestration and payment flows into risk-based test plans, and prioritise high-risk scenarios for automation.
• Build and maintain your pod's API test suites in Java and REST Assured, going beyond the happy path: auth, idempotency, error codes, retries and data integrity.
• Write and maintain Pact contract tests (Pact JVM) for your pod's services, including provider verification and can-i-deploy checks in CI.
• Run structured exploratory testing on new features, especially money movement, onboarding and multi-step journeys.
• Own scenario-level test data for your suites, using our shared data seeding mechanism.
• Keep your suites running in CI/CD on every change, within agreed runtime and flake budgets, and fix flaky tests at the root cause.
• Help investigate production issues with engineering, and add regression tests so they don't recur.
• Report coverage and quality metrics, and give input to release go/no-go decisions.
• Use AI tools (e.g. Copilot, Claude) for test generation, test data and defect triage, and share what works with the team.

• 5+ years in QA or quality engineering, with at least 3 years building API test automation in a product engineering team.
• Strong Java skills (or another JVM language), writing clean, maintainable framework code, not just test scripts.
• Deep hands-on experience with REST Assured (and ideally Postman/Newman) for API testing.
• Hands-on experience with Pact or similar contract testing: consumer and provider tests, a Pact Broker, and verification in CI/CD.
• Strong functional testing skills: risk-based test design, boundary and negative testing, and clear test plans other people can follow.
• Solid understanding of REST APIs: HTTP semantics, status codes, auth (OAuth 2.0, JWT) and schema validation (OpenAPI, JSON Schema).
• Working knowledge of CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI or similar) and diagnosing flaky tests.
• Practical experience using AI tools to write, review or maintain code and tests.
• Comfortable in a fast-moving startup environment, balancing speed with the rigour needed when testing financial systems.
• Willing and able to be in our London office four days per week.
• Будет плюсом: Experience in fintech, payments or another regulated financial services environment; Familiarity with payment schemes, ISO 20022, card processing or open banking; UI or mobile automation (e.g. Playwright for Java, Selenium, Appium) where it complements an API-first approach; Exposure to AI-driven test tooling, such as self-healing tests or intelligent test selection; Working knowledge of performance testing (e.g. Gatling, JMeter), enough to add basic checks to your pod's suites

• This role is predominantly office-based in Paddington, London.
• At Hyperlayer we are proud of our in-office culture. It makes a real difference to the working atmosphere and maximises collaboration in and across teams. This is critical to how we work and learn. Also, we think it makes for a great workplace!
• A performance-based employee bonus scheme.
• 25 days annual leave plus bank holidays, a day off on your birthday, and an additional day per year of tenure to a maximum of 30.
• Critical illness and life insurance cover.
• AXA PPP Health Insurance, including gym offers.
• Cycle-to-work scheme.
• Referral bonus scheme.
• Workplace nursery scheme.
