Job description

Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones. This multi-billion dollar market has been overlooked for decades, left to cobble together solutions that slow them down instead of helping them grow.

Quo is changing that. We bring calls, texts, and customer information together into one easy-to-use, AI-powered platform. We're not just building a phone system. We're setting a new standard for how businesses connect with their customers.

Driven by our values, we move fast, build with determination, and obsess over delivering value to the businesses that have been underserved for far too long.

Today, Quo is trusted by more than 120,000 companies and rated #1 in customer satisfaction on G2. We're backed by Y Combinator, Tiger Global, Craft Ventures, Slow Ventures, and other top-tier investors. It is safe to say we're onto something big.

About the Role

We're looking for a QA Automation Engineer (SDET), Web to help build and maintain the shared test automation platform that Quo's engineering teams rely on. This is a mid-level role on our growing Quality Engineering team — one of two Automation Engineer hires (this web-focused role and a mobile-focused counterpart) opening alongside a Quality Ambassador req from the same headcount round.

Per our Test Automation Philosophy & Ownership Framework, feature teams own the tests that validate what they build, at every layer including end-to-end; our Automation Engineers own the shared platform underneath — the frameworks, harnesses, and canonical patterns (Playwright, our API contract harness) — plus the specific cross-team suites nobody else owns, like web smoke tests. You'll help build and maintain that platform, not absorb test-writing from feature teams.

You'll join a small, fast-moving Quality Engineering team that's actively redefining how automation and manual QA work together, reporting to our Director of Quality Engineering.

Some of the things you'll do:

• Own and extend our shared web test platform: the Playwright framework feature teams build their own tests on top of, and our API contract harness, working alongside our mobile automation engineer who owns the Maestro side

• Contribute to coverage-gap audits across backend API and end-to-end tests, turning findings into real, owned test coverage

• Diagnose and drive down flaky tests in CI — telling the difference between a flaky test, an unstable environment, and a real regression

• Help maintain and extend tooling that turns customer-reported bugs into scoped coverage-gap work

• Own specific cross-team suites nobody else owns, including web smoke tests

• Partner constantly with backend, web, and mobile engineers to embed testing patterns into their workflow

• Help socialize canonical testing patterns and standards to squads as they mature

About You

• 3+ years of professional software engineering or SDET experience, with meaningful time spent building and maintaining test automation, not just writing individual test cases

• Strong TypeScript/Node.js skills, with hands-on experience in tools like Playwright (web E2E) and Vitest (backend/unit)

• Comfortable reasoning about cost/confidence tradeoffs — which layer of the test pyramid actually earns its cost for a given risk, rather than defaulting to end-to-end for everything

• Interested in building shared harnesses and canonical patterns other engineers build on top of, not just adding one-off tests

• Able to systematically diagnose and drive down flake rate in CI

• Understands how to validate a public or internal API's contract (auth, request/response shapes, error codes) independent of full end-to-end coverage

• Comfortable working from coverage and defect-escape dashboards to prioritize what gets automated next

• Collaborative by default — you'll partner constantly with backend, web, and mobile developers

Nice to have:

• Exposure to declarative, YAML-based mobile test automation (Maestro or similar)

• Comfort reading someone else's test suite, extending it with new coverage, and debugging why a test broke

• Experience working in a fast-moving, still-forming engineering organization

Compensation

The annual base salary range for this position is as follow, plus equity and benefits:

• SF Bay Area, Los Angeles, Seattle, Portland, Boston, New York, and Washington, DC Metro: $136,000 - $159,000 USD

• All other US Locations: $122,000 - $143,000 USD

• Canada: $124,000 - $145,000 CAD

The ranges displayed reflect the target for new hire salaries, and within each range, individual pay is determined by your skills and experience, as well as relevant education. Your recruiter can share more and answer questions about the specific salary range during the hiring process.

Salary is just one component of Quo's total compensation package. Your total rewards package will include equity, extensive medical coverage, a monthly lifestyle stipend, and a flexible PTO policy.
