We’re looking for a QA Engineer to join our Data and AI Engineering team. This is a mid-senior role for someone who can own test planning and execution independently for designing test strategies, building automated regression coverage, and safeguarding release quality without needing close supervision.

We welcome QA engineers who take as much pride in rigorous, well-documented testing as in finding the edge cases.

Responsibilities

What You’ll Do
- Own test strategy end-to-end for features and releases as defining scope from specs and user stories, designing test plans, and executing them systematically with minimal oversight.
- Build and maintain automated regression suites (Selenium, Playwright, or Cypress) integrated into CI, plus API-level tests (Postman, pytest + requests) that validate endpoints independently of the UI.
- Raise, triage, and track defects with clear severity classification, and drive them through to resolution.
- Coordinate regression testing cycles and UAT with business stakeholders ahead of releases.
- Produce clear documentation like process runbooks,



incident reports (root cause, impact, timeline, resolution), and test strategy/spec documents ready for stakeholder sign-off.
- Collaborate with developers, product, and business stakeholders to translate requirements into testable, traceable acceptance criteria.
- Apply the traceability and version-control discipline expected of QA work in a regulated environment.

Requirements - Must have - What We’re Looking For

We’re committed to building a skilled and diverse engineering team. If you care deeply about writing clean code, delivering resilient systems, and collaborating across disciplines then this role is for you.

Core Experience & Skills
- Test Planning & Execution: proven ability to own a test strategy end-to-end from a spec or user story with minimal guidance such as scope definition, traceable test cases, systematic execution, and release sign-off.
- API Testing: comfortable valida
