Sr. Software Engineer In Test - Embedded Payments

About the opportunity

Join our Embedded Payments team as Sr. Software Engineer in Test in Pune, India to make a real impact every day. We say that because we know that every conversation we have, every code line we write and every interface we design is another opportunity for us to elevate everyday life experiences for our customers and the people and communities they serve.

Reporting into the Director of Software Engineering, you will help lead the technical direction of our QA engineering function. You're joining a team that already has strong Playwright-based automation in place, owned by our Sr. QA Automation Engineer. Your job is to collaborate on that foundation, bring best engineering practices to the forefront, and help evolve it into something the rest of the team can grow into.

This role carries real technical ownership. You will design framework architecture, drive load and async testing capabilities, integrate quality deeply into CI/CD pipelines, and be the person engineering and product turn to when they need to understand risk. You'll work closely with our Sr. QA Automation Engineer, contributing engineering rigor to what's already working while expanding what's possible.

Our platform is a cloud-native, event-driven payment orchestration system processing high transaction volumes across multiple clients and acquirers. Load testing and async workflow validation are not edge cases here -- they are core to how we define done.

Our Tech Stack 

• Front-end:  React (CRA), Material-UI, JavaScript 
• Testing:  Jest, ESLint, Prettier, Storybook, Playwright, K6 
• Backend:  Node.js, AWS deployed on ECS, RDS, API Gateway, Lambda, Cognito 
• Messaging:  SQS, EventBridge, Lambda (event-driven async workflows) 
• DevOps:  Bitbucket Pipelines, Terraform 

Responsibilities 

• Collaborate with the Sr. QA Automation Engineer on test framework architecture -- contributing engineering best practices, evolving shared standards, and helping mature the Playwright suite and shared test infrastructure across the engineering organization.
• Define and lead the load and performance testing strategy -- scenario design, tooling selection, baseline definition, and translating results into engineering decisions.
• Build and own test harnesses for async, event-driven workflows -- validating SQS-driven processes, EventBridge patterns, and Lambda invocations where outcomes are eventual rather than immediate.
• Establish patterns for testing correctness in async financial operations: retry logic, idempotency, dead letter queue handling, and state consistency across distributed service boundaries.
• Own CI/CD quality gate configuration -- pipeline integration, parallel execution strategy, failure triage, and signal quality (low noise, high defect detection).
• Drive API and contract testing strategy across services, ensuring integration failures are caught well before production.
• Build quality observability into the engineering process: coverage trends, flakiness dashboards, test metrics, and regression-to-incident traceability.
• Collaborate with engineering leads during design and architecture — representing quality risk as a first-class input to technical decisions. 
• Set the standard for AI-assisted test engineering on the team — actively using and evangelizing tools like GitHub Copilot, Claude, or Cursor for test authoring, gap analysis, and triage. 
• Mentor and technically guide QA team members, building SET capability across the function over time. 
• Identify systemic quality gaps and drive engineering-level solutions, not just additional test cases.
