QA Automation Engineer (SDET), Mobile

Small businesses represent 99.9% of all companies, yet they're still forced to choose between clunky, outdated enterprise phone systems or their personal phones.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's safe to say we're onto something big.

About the Role

We're looking for a QA Automation Engineer (SDET), Mobile to help build and maintain the shared test automation platform that Quo's engineering teams rely on, with a focus on our mobile apps. This is a mid-level role on our growing Quality Engineering team - one of two Automation Engineer hires (this mobile-focused role and a web-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 (Maestro, Playwright, our API contract harness) - plus the specific cross-team suites nobody else owns, like smoke tests and the mobile device/OS matrix. In this role, you'll own the mobile side of that platform. You'll help build and maintain it, 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 mobile test platform: the Maestro framework feature teams build their own tests on top of, working alongside our web automation engineer who owns the Playwright side

• Own the mobile device/OS matrix, along with mobile smoke tests and other cross-team mobile suites nobody else owns

• Contribute to coverage-gap audits across mobile and backend API 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 or device, and a real regression

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

• Partner constantly with mobile, backend, and web engineers to embed testing patterns into their workflow, including how shipping mobile differs from shipping web

• 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

• Hands-on experience with mobile test automation tools like Maestro or Appium (or similar) on native mobile apps

• Comfortable owning device and OS matrix testing, and you understand how deploying mobile differs from deploying web (for example, store release cycles and device/OS fragmentation)

• 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

• Strong programming skills, ideally in TypeScript/Node.js

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

Nice to have:

• Exposure to Playwright (web E2E) and Vitest (backend/unit), so you can work closely with your web automation counterpart

• 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

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.
