About The Role We are a: 15-person health-tech B2B platform running a serverless-first AWS stack (Lambda, API Gateway, RDS, Amplify, Cognito).

We’re looking for a QA Engineer / SDET who writes test code, owns test infrastructure, and is fluent in using AI tooling to author and maintain tests — as well as testing AI-powered features themselves.

You’ll be the person who turns "we keep shipping regressions" into a durable, automated safety net.

This is a hands‑on, code‑writing role.

You’ll work directly with a small engineering team and own QA strategy end‑to‑end.

What you’ll do - Design and maintain end‑to‑end and regression test suites in Playwright (our current framework), including using `codegen` and AI‑assisted authoring to accelerate coverage. - Use AI tooling (LLM‑based test generation, self‑healing selectors, AI code assistants) to reduce the cost of writing and maintaining tests — with judgment about where AI helps and where it introduces flakiness. - Test LLM‑and MCP‑powered product features: build evaluation harnesses,



define quality bars for non‑deterministic outputs, and design guardrail/regression checks for natural‑language and agent‑driven workflows. - Attack our three standing testing gaps: mock drift, untested Lambda infrastructure, and recurring regressions that ship without accompanying tests. - Build post‑deploy smoke tests and contract tests against our integration layer (Hub

Spot, Dwolla, Intercom, Post

Hog, Slack). - Partner with engineering to enforce a Definition of Done that requires tests, and embed QA into the sprint cadence rather than bolting it on at the end.

Must-have - Strong Java

Script/Type

Script; you write and maintain test code, not just test plans. - Production experience with Playwright, Cypress, or equivalent modern E2E frameworks. - Hands‑on experience using AI tools in a real testing workflow (test generation, maintenance, or triage). - Experience testing non‑deterministic / AI‑powered systems, or a clear, credible approach t...
