Join our Technology R&D Lab as a Test Engineer building the next generation of API-first, composable banking solutions. You will create and maintain automated testing for our IBOR (Investment Book of Record) platform — a multi-tenant SaaS system serving financial institutions globally. Working closely with our backend engineering team, you'll design testing strategies for our serverless, event-driven architecture running on AWS, ensuring quality, compliance, and resilience as we rapidly deploy new features.
Job Responsibility:
Design and maintain automated API testing frameworks using tools like Postman/Newman, REST Assured, or similar for TypeScript/Node.js services
Build integration test suites for event-driven architectures (SQS message flows, Lambda functions, DynamoDB operations)
Develop performance and load testing scenarios for serverless applications using k6, Artillery, or Gatling
Create test strategies for financial calculation accuracy (performance attribution, time-weighted returns, position keeping)
Integrate automated tests into GitHub Actions CI/CD pipelines to enable continuous testing and rapid feedback
Implement test data management strategies for multi-tenant environments with isolated tenant testing
Partner with backend engineers to define testable service contracts and API specifications
Champion quality engineering practices including test coverage analysis, mutation testing, and regression prevention
Requirements:
3-5+ years of experience in API and backend testing for distributed systems
Strong experience with TypeScript or Node.js testing frameworks (Jest, Mocha, Chai, Supertest)
Proven experience testing REST APIs and asynchronous/event-driven architectures
Hands-on experience with AWS services: Lambda, DynamoDB, SQS, S3
Experience with API testing tools (Postman, REST Assured, or similar)
Understanding of CI/CD pipelines and automated testing integration (GitHub Actions preferred)
Strong collaboration skills and ability to work closely with engineering teams in an R&D environment
Experience testing serverless applications and understanding Lambda execution models
Knowledge of financial services systems (IBOR, portfolio accounting, performance calculations)
Nice to have:
Experience with performance testing tools for serverless (k6, Artillery, serverless-artillery)
