## About the Role

Engineering craft

 * 5+ years as a software engineer with a fullstack mindset - comfortable moving across the stack, not living in one layer.
 * Strong coding ability in at least one of TypeScript/JavaScript, C#/.NET, or Python, and productive in the others.
 * Experience integrating automated tests into CI/CD pipelines as reliable quality gates.

Quality expertise

 * Deep, hands-on experience building automated tests at every level - unit, integration, and end-to-end - not just running them.
 * Formal QA experience and a tester's instinct: you know how to vet a feature across the full stack (integration, data, backend, web/mobile) and what needs verifying at each layer.
 * A "QA as code" philosophy: tests and infrastructure live in version control, get code-reviewed, and are built for maintainability.
 * Fluency with modern test tooling (Playwright/Cypress-class E2E, API testing, mocking/fixtures) and a habit of picking the right tool per layer.

Ownership & AI-native

 * Able to own an area end-to-end with limited guidance and establish patterns from scratch.
 * AI-native by default: you use AI tools to multiply your output - and verify what they produce.

Preferred Skills

 * Founding-team or early-stage experience building a quality function from zero on a lean team.
 * Familiarity with agentic and AI-native testing tooling (e.g. Momentic, self-healing E2E frameworks).
 * Experience evaluating AI/LLM features - evals, golden datasets, or regression harnesses for non-deterministic systems.
 * Automated mobile testing (iOS/Android).
 * Data / ETL / pipeline testing and data-quality validation.
 * Performance, load, or security testing exposure.
 * Contract testing, observability, and using production signals to inform coverage.
 * Proptech, real estate, fintech, geospatial, or SaaS data-product experience.
