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.
