Quality Engineer

Duetto is building its quality engineering function from scratch — and this is the first hire that will define what quality engineering means across the organisation. This isn't a traditional QA gatekeeper role: developers own testing at Duetto, and you'll be the person who coaches, enables, and builds the shared infrastructure that makes high-quality testing the path of least resistance. The timing is significant — a live monolith-to-microservices migration, a frontend migration to Playwright, and a shift to AI-generated code at scale. Each demands someone who can design test strategy for a system in motion.

Duetto is the hospitality industry's leading revenue management platform, founded in 2012 by former Wynn Resorts executives who knew the industry needed better technology. We built the world's first Revenue & Profit Operating System — a suite of tools (GameChanger, ScoreBoard, BlockBuster, Advance and more) that goes beyond room pricing to give hotels, resorts and casinos a complete picture of their revenue and profitability. Trusted by clients ranging from independent boutique hotels to global chains, we've been named the #1 Revenue Management Software by HotelTechAwards four years running and the #1 Best Place to Work in Hotel Tech in 2025. Backed by GrowthCurve Capital since 2024, we're accelerating our investment in AI — and we're genuinely passionate about the industry we serve. We build products we're proud of, for customers we care about.

• →You'll define and own quality gate logic within CI pipelines — coverage thresholds, mutation score gates, contract test enforcement, flaky test quarantine rules, and test result reporting — and build DataDog quality dashboards tracking test health, coverage trends, and flaky test rates across the engineering organisation.
• →You'll lead and execute the migration from Selenium and Cypress to consolidated Playwright (currently 26% complete), using Claude Code to accelerate AI-assisted test migration at scale — designing the shared Playwright configuration, CI sharding strategy, and page object library, and consolidating from three E2E frameworks to one.
• →You'll design and implement Pact contract testing for service boundaries created during the monolith-to-microservices extraction — managing the Pact broker, establishing consumer-driven contract testing as standard practice, and owning API contract testing for GraphQL and REST service contracts.
• →You'll design and maintain Testcontainers configurations for MongoDB, PostgreSQL, Redis, LocalStack, and RabbitMQ, and drive PR pipeline test execution toward the P90 target of under 15 minutes.
• →You'll champion AI-augmented testing practices using Claude Code, CodeRabbit, and Augment — evaluating and reviewing AI-generated test code for correctness and coverage gaps in a codebase where 50–70% of code is already AI-generated.
• →You'll coach developers on testing practices and automation patterns, establish mutation testing using PIT (Java) and Stryker (JavaScript/TypeScript), and mentor junior QEs as the quality engineering function grows.

You may be a good fit if you have:

• Strong experience with Playwright for end-to-end test automation, including page object patterns and CI integration
• Hands-on experience defining and implementing quality gates within GitHub Actions pipelines
• Contract testing experience — Pact experience strongly preferred
• Proficiency in both Java and TypeScript/JavaScript for test implementation
• Experience with Testcontainers or equivalent integration test infrastructure
• Demonstrated ability to reduce test flakiness at scale
• Strong understanding of test strategy for distributed systems and service-oriented architectures
• Active experience using Claude Code or similar AI coding assistants for test generation and automation — you understand that AI-generated code requires a different quality practice, not a lighter one

Strong candidates may also have:

• Experience migrating legacy E2E frameworks (Selenium, Cypress) to Playwright at scale
• Familiarity with mutation testing tools — PIT for Java, Stryker for JavaScript/TypeScript
• Experience with performance testing using k6
• Background in hospitality technology or complex B2B SaaS environments

• You'll build something that doesn't exist yet. This is the first senior QE hire at Duetto — the practices, infrastructure, and standards you establish will shape how the entire engineering organisation approaches quality for years.
• AI-first testing, for real. With 50–70% of code AI-generated and Claude Code already in the daily workflow, you'll be pioneering what quality engineering looks like when the code generation model fundamentally changes — not theorising about it.
• Architectural impact at scale. The monolith-to-microservices migration is live, the Playwright migration is underway, and the contract testing infrastructure needs building — the problems are real, the timing is right, and the infrastructure you design matters.
• Modern tooling throughout. Playwright, Testcontainers, Pact, k6, GitHub Actions, DataDog — no legacy constraints holding you back.
• A clear growth path. Senior QE (L5) to Staff/Lead QE (L6) as the quality engineering function matures and grows.

• Location: Remote (Croatia)
• Team: Quality Engineering

Duetto is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
