QA Software Engineer

Nest builds care plan infrastructure for veterinary hospitals. Corporate veterinary groups use Nest to run preventive care memberships under their own brand, and we handle what sits underneath: enrollment, recurring billing, analytics, marketing, and seller-of-record compliance.

Care plans change how pets receive care. Pet owners pay a predictable monthly amount, visit more often, and catch problems earlier. Hospitals build steadier revenue and longer client relationships. Our mission is to make that kind of preventive care available to every pet., Hospitals use Nest to enroll pet owners and collect recurring payments, so a defect can mean a failed charge or a front desk team that cannot finish an enrollment. You will build how quality works at Nest: the test suites, the release checks, and the reliability standards. We expect much of this work to be AI-assisted, with generated tests that you review and maintain rather than write from scratch. The role rewards judgment about which small share of paths carries most of the risk. After a year, engineers will ship with confidence in the flows that matter most, and release readiness will be visible to the whole team., * Build test suites for our Flutter web and desktop applications and our FastAPI and gRPC services.

• Write contract and integration tests for critical APIs, including payment processing and PIMS integrations.
• Use LLMs to generate test cases from specs, pull requests, and code diffs, and curate the output into a maintained suite.
• Use AI-assisted exploratory testing to surface edge cases across app state, API responses, and UI structure.
• Set up visual regression testing for our admin and hospital-facing interfaces.
• Define error budgets, alert thresholds, and resilience tests with engineering.
• Create defect triage workflows and quality reporting that show coverage and release readiness.

• You have 3 or more years in QA, SDET, or test automation, with an automation-first background.
• You use AI tools such as Claude, Copilot, or Codex in your testing work today. We will ask for specific examples.
• You have strong Dart and Flutter testing experience, including unit, widget, golden, and integration tests.
• You drive API tests with AI and Postman.
• You know sql and can validate data and set up test data in a relational DBMS., * Experience testing Flutter Web with Playwright or similar, or testing Flutter Desktop applications.
• Experience with contract testing or API testing frameworks.
• Familiarity with Sentry or Datadog and with SLOs and error budgets.
• Experience building a QA function from the ground up.

Nest is a small, fully remote team. Each person owns outcomes the company depends on, and the scope of most roles grows as the company does. We write decisions down, give direct feedback, and expect problems to be raised early. The work is demanding because hospitals and pet owners rely on it every day, and it suits people who want more ownership than a larger company would offer.
