Overview

We are looking for a Staff QA Engineer to join the Buying and Optimization team.

Responsibilities

- Design, build, and maintain Tatari’s end-to-end (E2E) test automation framework in Playwright. Write a large share of the core framework code, shared utilities, and the hardest test suites yourself.

- Set the technical direction for test automation, including tooling, architecture, and testing patterns, and turn it into reference code and design docs others can follow.

- Write and improve unit and integration tests across the stack (TypeScript/Jest, Python/pytest). Build the patterns, fixtures, and helpers that make good testing the easiest path for QA engineers and feature teams.

- Integrate automated tests into CI/CD pipelines; fix flaky tests, speed up test runs, improve pipeline observability, and build reliable release gates.

- Build tooling for data validation and backend verification, including SQL-based data integrity checks, API contract and response validation, and test data setup for sandbox and staging environments.

- Do hands-on exploratory testing on the highest-risk workflows, and review test plans and automation code written by other engineers.

- Act as the senior technical voice for QA. Give engineering and product leadership risk assessments and coverage data to inform release decisions.

- Raise the testing bar across engineering by mentoring, pairing, and writing best-practice docs. Take part in technical interviews for QA candidates.
