Job Responsibilities 

• Design automation-first test suites (UI, API, integration, regression) integrated into CI/CD with measurable quality gates• Build scalable automation frameworks and standards to accelerate adoption and improve ROI• Implement stable UI automation for critical user journeys and entitlement-driven behaviors while reducing flakiness• Create API contract and integration tests from OpenAPI/Swagger specs covering schemas, compatibility, and error handling• Validate token lifecycle workflows (issuance/minting, transfer, burn/redemption) and reconcile ledger state across services• Automate end-to-end validations across UI + API + ledger workflows with disciplined evidence capture• Validate on-chain outcomes (success, receipts/confirmations/finality, balances/state, logs/events) and reconcile to internal state• Support multi-chain validation patterns for Ethereum Sepolia, Base (EVM), and Solana ecosystems• Verify JPMC approval for any third-party/external services (including Etherscan) before integration and use• Test payment-adjacent processing and settlement flows including reconciliation and resiliency/failover behaviors• Drive defect triage, retesting, root-cause analysis partnership, and data-driven quality metrics/reporting improvements

Required qualifications, capabilities and skills 

• Demonstrate 5+ years of SDET/Quality Engineering experience building and maintaining UI and API automation frameworks• Apply strong UI automation skills using Selenium, Playwright, Cypress, or equivalent frameworks• Build API automation using Swagger/OpenAPI artifacts and tools such as RestAssured, Karate, or Postman/Newman• Explain blockchain/DLT fundamentals and apply them to testing in distributed systems• Validate tokenization concepts and token lifecycle behaviors across services• Apply payments or payment-adjacent integration knowledge to end-to-end testing• Execute on-chain validation across public chains/testnets including EVM-based ecosystems (Sepolia/Base)• Apply Solana fundamentals to validation (signatures, confirmations/finality, account/program state checks)• Validate IAM controls including authentication/authorization, RBAC/ABAC, entitlements, audit logging, and negative testing• Automate SCIM provisioning integration tests across Users/Groups lifecycle, mapping, sync, retries, and failure modes

Preferred qualifications, capabilities and skills

• Build chain validation using RPC/provider interfaces for EVM chains and Solana across public and private networks• Apply contract testing and service virtualization/mocking strategies for complex dependency chains• Execute performance and reliability testing for API-heavy systems (latency, throughput, soak, resiliency/failover)• Validate event-driven architectures and message flows using strong observability practices

• Develop in Java (preferred) or another suitable language (Kotlin, Python, JS/TS) with strong troubleshooting and collaboration
