About the role
As our SDET, you will own the quality and integration testing strategy for a money-critical crypto exchange platform. You will build and maintain the integration test infrastructure that validates our Go backend services and React web application end-to-end, ensuring trading, wallet, and settlement flows are reliable, correct, and production-ready before every release.
Responsibilities:
- Design and build integration test frameworks in Go and/or Python that validate interactions across backend microservices, including order management, trade execution, wallet, market data, and settlement services.
- Build integration and end-to-end tests for the React web trading platform, covering critical user journeys such as placing orders, managing portfolios, and viewing market data.
- Own test pipeline stages in Azure Pipelines; define quality gates that block releases when integration or E2E tests fail.
- Create test data strategies and environment tooling for realistic exchange scenarios, including multi-service flows, partial fills, and cross-service state consistency.
- Drive performance and load testing for backend services using k6 or JMeter; define and track SLOs for critical trading flows.
- Collaborate with backend and frontend engineers on API contracts, integration points, and release readiness; document coverage gaps.
- Investigate production failures, reproduce defects in test environments, and contribute actionable findings to post-mortems.
Requirements:
- Strong programming skills in Go and/or Python; able to write clean, maintainable test code at production quality.
- Hands-on experience with API integration testing across microservice architectures (REST, gRPC, event-driven).
- Experience with web E2E automation tools such as Playwright or Cypress for testing React applications.
- Solid understanding of CI/CD pipelines, Azure Pipelines, and test environment management.
- Performance and load testing experience (K6 JMeter, or Gatling) with the ability to analyze and act on results.
- Strong quality mindset; clear communicator and collaborator.
- 3-5 years of experience in SDET, QA automation, or test engineering roles.
- Prior experience testing crypto exchanges, Web3 platforms, and onramp/offramp services; this is a mandatory requirement
- Built, maintained, and scaled integration and E2E test suites across both backend services and web frontends.
- Tested REST/gRPC APIs, event-driven systems, and complex stateful, data-driven flows.
Nice to Have:
- Familiarity with contract testing (e. g., Pact), chaos/resilience testing, and security testing fundamentals.
- Exposure to Azure Pipelines, Azure Test Plans, New Relic, and feature flagging tools.
- Understanding of financial transaction correctness, audit requirements, and cross-service consistency.
