Sr. QA Engineer

Job description

# **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
