Location: Miami
Workplace: Onsite
Employment Type: Full time
Job Function: QA, Test & Release Engineering
Seniority: Mid level

Key Responsibilities

  • •Own test strategy across internal engineering platforms and client-facing products, from unit/integration coverage to end-to-end and regression suites.
  • •Design, build, and maintain automated test suites in code (UI, API, and data-layer) that remain fast, deterministic, and trusted.
  • •Use LLM-assisted tooling to accelerate test authoring, generate edge cases, triage failing runs, and summarize regressions.
  • •Build and tune quality gates in CI/CD so broken builds do not reach client environments and feedback loops stay fast.
  • •Identify manual QA processes to automate out of existence, reproduce/triage defects with clear repro steps, and partner with security engineers to add security regression checks.

Key Requirements

  • •3 to 5 years in QA engineering, SDET, or test automation, with a demonstrated shift from manual execution to automated coverage.
  • •Strong programming ability in TypeScript, JavaScript, or Python to write test code engineers can maintain.
  • •Hands-on experience with automation frameworks such as Playwright, Cypress, Selenium, or pytest (or equivalent).
  • •Practical API testing experience, including contract, integration, and negative-path testing against REST or GraphQL services.
  • •Comfort owning CI/CD pipeline configuration and using tools such as GitHub Actions, GitLab CI, or Jenkins.
