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.
