Senior QA Engineer

Overview

In this role you will be responsible for : Define, own and execute the QA strategy for features and releases across web, mobile and API surfaces. Design and implement automated test suites for end-to-end flows (UI + API) and regression coverage using modern frameworks (e.g., Playwright / Cypress / Selenium + test runners). Build and maintain API test automation (contract tests, integration tests, fuzzing) for REST / GraphQL endpoints and webhooks. Create and run performance, load and scalability tests (JMeter, k6 or equivalent) and help the team identify bottlenecks and capacity limits. Lead security-oriented testing for features handling sensitive data (data masking, auth flows, role / permission checks, injection testing). Write clear test plans, acceptance criteria, test cases and QA tickets; triage defects and validate fixes across environments. Integrate tests into CI / CD pipelines, ensure reliable test runs, flakiness reduction, and fast feedback loops for PRs. Collaborate with SRE / DevOps to surface telemetry, logs and metrics required for observability and post-release validation. Drive root-cause analysis for production incidents and contribute to post-mortems and corrective action plans. Coach and mentor QA engineers and help establish best practices (exploratory testing, shift-left testing, test data management). Own release gating criteria and help the Product / Engineering leadership make informed go / no-go decisions. Skills
