Role Summary: We’re hiring two Senior QA Engineers to own end-to-end quality for mission-critical fintech flows (payments, wallets, ledgers, event-driven workflows, and regulatory scenarios).
You’ll be the final quality gate before production and have the authority to block releases when signals aren’t green.
Key Responsibilities: • Own E2E automation: design, build, and maintain robust frameworks that cover API + UI + data layers.
• Validate event-driven workflows: test Sagas, retries/compensations, idempotency, duplicates, and out-of-order delivery across microservices.
• Guard ledger integrity: verify double-entry accounting, append-only immutability, balance reconciliation, and safe rollbacks.
• Contract & integration testing: enforce OpenAPI/Swagger contracts; test gateways, banking APIs, and webhooks (retries + signature verification).
• Performance & reliability: run load and soak tests (k6/JMeter), surface bottlenecks, and prove concurrency safety.
• Database validation (MongoDB): assert ACID transaction outcomes, aggregation pipeline results, and no mutation of historical financial data.
• Ship with discipline: work closely with Backend, SRE, and Product; gate releases across Dev → QA → UAT with meaningful failure diagnostics.
• Partner with Product & QA to craft acceptance criteria and run manual exploratory passes before handoff to UAT.
Automation & Tooling (6+ yrs QA/Automation): • Playwright or Cypress (API + UI) and code-based API testing; TypeScript/JS preferred.
Manual Testing Fundamentals (required): • Exploratory testing (session-based test management, charters, mind maps).
• Test design techniques: boundary value analysis, equivalence partitioning, decision tables.
• Functional & regression: smoke/sanity, targeted regressions, cross-browser/device checks.
• UAT readiness: collaborate on acceptance criteria; prepare happy-path/edge-path suites.
• Bug quality: crystal-clear repro steps, expected vs actual, risk articulation, triage participation.
Backend & System Understanding: • Microservices + event-driven systems (Kafka/RabbitMQ/NATS), async testing (retries, dedupe, replay).
Financial & Ledger Testing: • Double-entry accounting, wallets, amortization; decimal precision awareness (no float footguns).
Database Validation (MongoDB): • Assertions on transactions, aggregation pipelines, and immutability constraints.
Performance & Reliability: k6/JMeter; design tests for idempotency under load, race conditions, and concurrency safety.
CI/CD & Env Awareness: Git pipelines; Dev/QA/UAT flows; ability to block releases on objective quality signals with solid diagnostics.
Nice to have: • Regulated fintech/payments exposure, webhook security/signatures, observability (Grafana/Prometheus/OTel).
• ISTQB or equivalent is fine, but hands-on thinking > certificates.
