job description
What you’ll be focusing on:
- Developing and maintaining the automated e2e suite (Playwright + TypeScript) covering both UI and API layers of the payments platform.
- Automating critical payment scenarios: checkout and 3DS challenge flows, authorization, capture, void, refunds, chargebacks.
- Building API test suites for internal services and third-party provider integrations.
- Automating routing, cascading and retry scenarios, and subscription/recurring billing flows.
- Validating data integrity across storages (Postgres, ClickHouse, OpenSearch) as part of automated checks.
- Owning suite health: triaging failures, distinguishing real defects from flakiness, and fixing the root cause.
You are our ideal candidate if you:
- Have 2+ years of experience in test automation, preferably within fintech, payments or e-commerce.
- Have strong JavaScript/TypeScript skills — able to write and maintain a test framework, not just test scripts.
- Have hands-on experience with a modern e2e framework (Playwright preferred; Cypress/Selenium/WebdriverIO acceptable with willingness to move to Playwright).
- Have solid API test automation experience — REST, request/response structures, status codes, authentication (OAuth2/OIDC, API keys), contract and negative testing.
- Have good architectural habits in test code: Page Object / fixtures, reusable helpers, environment-driven configuration, test data management and cleanup, avoidance of inter-test coupling.
- Are able to write stable, deterministic tests against async, event-driven systems — explicit waits/polling instead of sleeps, retry-tolerant assertions, diagnosing and eliminating flakiness.
- Have a solid understanding of software testing fundamentals: test design techniques, coverage analysis, bug lifecycle, when automation is (and isn't) worth it.
- Have good SQL skills — writing queries against Postgres to validate transaction states and payment data as part of automated checks.
- Have practical CI/CD experience — running suites in a pipeline (GitLab CI preferred), reading job logs, publishing JUnit/HTML reports, handling env-specific runs.
- Are familiar with payment gateway flows: authorization, capture, refunds, chargebacks, 3DS authentication.
- Have knowledge of web testing basics: browsers, dev console, network tab, debugging front-end/back-end boundary issues.
- Nice to have: Kafka/async message validation, ClickHouse or OpenSearch, Docker/Kubernetes basics, performance testing (k6/JMeter), Grafana and log-based investigation, understanding of PCI-DSS requirements.
