Job description

Описание

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.

Задачи

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.

Требования

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
