Your Next Career Move Starts Here
We are actively hiring across engineering, cloud operations, and data. These are not support roles — you will own outcomes, work directly with enterprise clients, and build systems that run at scale.
SDET – Test Automation & Performance Engineering (Mid-Level)
Own the quality engineering strategy for enterprise applications serving our healthcare and financial services clients — across both functional and non-functional testing. This is a hands-on SDET role where you design, build, and maintain end-to-end automation with Playwright, covering both the UI and API layers, and drive automation coverage to a minimum of 90% across critical user journeys. You will strategically manage the balance between automated and manual test cases — deciding what to automate and what to explore manually — and own the regression suite that gates every release. Beyond functional testing, you will design and execute performance and load tests with k6: modeling realistic traffic, establishing response-time and throughput baselines, and surfacing bottlenecks before they reach production. You will integrate test suites into CI/CD pipelines for fast, reliable feedback, collaborate closely with developers, DevOps, and product teams, triage and report defects with clear reproduction steps, and champion a quality-first culture across the engineering organization.
Requirements
- 5+ years of experience in software testing / SDET roles, with a strong focus on test automation
- Expert-level proficiency with Playwright for both UI and API test automation
- Proven experience designing and maintaining end-to-end, integration, and API automation frameworks from the ground up
- Ability to strategically balance automated and manual testing, and sustain a minimum of 90% automation coverage on critical paths
- Hands-on experience with performance and load testing using k6 — scripting scenarios, setting baselines, and analyzing results
- Strong understanding of both functional and non-functional testing (performance, load, reliability, scalability)
- Experience integrating automated test suites into CI/CD pipelines (GitHub Actions, Azure DevOps, or Jenkins)
- Solid grasp of REST API testing — request/response validation, authentication flows, and data-driven testing
- Proficiency in a scripting/programming language (TypeScript/JavaScript preferred; Python a plus)
- Experience with test management, defect tracking, and reporting tools (e.g., Jira, TestRail, Allure)
