Sr. QA Engineer

SENIOR QA ENGINEER THE ROLE We're hiring a Senior QA Engineer to own testing across our Software Development Life Cycle (SDLC). This is a strategy-and-automation role, not a click-testing one: you'll own the test strategy, write the test cases, and automate them on top of established open-source testing tools — working shoulder-to-shoulder with developers to bake quality in from the start rather than catch it at the end.

This role partners closely with product and platform engineering.

WHAT YOU'LL DO

• Own the test strategy end-to-end across the SDLC.
• Build and own test coverage on top of established open-source testing tools — defining the strategy, writing the test cases, and automating them — and integrate it into our Continuous Integration / Continuous Delivery (CI/CD) pipelines so tests run on every meaningful change.
• Write clear, maintainable test cases and test plans, and keep them current as the product evolves.
• Plan and run the full range of testing — including but not limited to integration testing, system testing, regression testing, and stress / load / performance testing.
• Partner with developers to define acceptance criteria, shift testing left, and make quality a shared responsibility rather than a gate at the end.
• Triage failures, drive root-cause analysis on escaped defects, and close the loop with durable fixes.
• Report quality signals (coverage, flake rate, escaped defects) in a way the team can act on.

WHAT YOU'LL NEED

(REQUIRED)

• Strong test automation skills, with a track record of designing test strategy and automating it on top of established open-source testing tools.
• Deep, practical understanding of the SDLC and where testing fits at each stage.
• Proven experience writing test cases and test plans.
• Hands-on experience across multiple testing types: integration, system, regression, and stress / performance.
• Experience integrating automated tests into CI/CD pipelines.
• Strong communication skills — you work directly with developers and can make a clear, persuasive case for quality.
• Sufficient experience with Python, JS/TS NICE TO HAVE
• Strong experience with Python, JS/TS
• Familiarity with open-source testing tools (for example, Playwright or Cypress for end-to-end, pytest for unit and integration, k6 or Locust for load and stress testing).
• Exposure to testing cloud or containerized (Kubernetes) workloads.
• Experience supporting a System and Organization Controls 2 (SOC 2) or similar compliance program by producing test evidence.
• Background in enterprise or regulated environments where reliability is non-negotiable.
• Experience in early-stage environments where one person owns a broad testing surface. WHAT SUCCESS LOOKS LIKE (FIRST 90 DAYS)
• You've assessed current test coverage and identified the highest-leverage gaps.
• Automated test coverage is running in the pipeline on every meaningful change.
• The team has a clear, lightweight process for triaging failures and preventing repeat defects. LOCATION AND WORK MODEL Remote in South America/Mexico/India/LATAM
