[Hiring] Quality Engineer @Duetto Research

Role Description

Duetto is building a quality engineering function from scratch, and this Senior QE role is the first hire that will define what quality engineering means at the company. This is not a traditional QA gatekeeper role. Duetto's quality model is a hybrid/guild approach: developers own testing, and QEs coach, enable, and build shared infrastructure that makes high-quality testing the path of least resistance.

The timing is significant. Duetto is in the middle of three simultaneous transformations: a 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.

You will be placed on the central quality engineering team or embedded in a high-priority product team, depending on organizational need at the time of hire.

What you'll do

• Test automation architecture and quality gates (35%)
  • 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.
  • Implement flaky test auto-quarantine logic: tests failing more than 3 times in 7 days are quarantined and ticketed.
  • Design and maintain Testcontainers configurations for MongoDB, PostgreSQL, Redis, LocalStack, and RabbitMQ.
  • Build and maintain DataDog quality dashboards tracking test health, coverage trends, and flaky test rates.
  • Drive PR pipeline test execution toward the P90 target of under 15 minutes.
• Selenium-to-Playwright migration (25%)
  • Lead and execute migration from Selenium and Cypress to consolidated Playwright (currently at 26% completion).
  • Use Claude Code to accelerate AI-assisted test migration at scale.
  • Design the shared Playwright configuration, CI sharding strategy, and page object library.
  • Own consolidating from 3 E2E frameworks to 1 (Playwright).
• Contract testing and microservices quality (20%)
  • Design and implement Pact contract testing for service boundaries created during monolith-to-microservices extraction.
  • Manage the Pact broker and establish consumer-driven contract testing as standard practice.
  • Work with teams on API contract testing for GraphQL and REST service contracts.
• Developer coaching and quality culture (20%)
  • Coach developers on testing practices and automation patterns.
  • Champion AI-augmented testing practices using Claude Code, CodeRabbit, and Augment.
  • Establish mutation testing practices using PIT (Java) and Stryker (JavaScript/TypeScript).
  • Mentor junior QEs as the team grows.

Qualifications

• 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.

Requirements

• Duetto operates in an AI-first engineering environment. This role requires active use and advocacy of AI tooling.
• Experience using Claude Code or similar AI coding assistants for test generation and automation.
• Ability to evaluate and review AI-generated test code for correctness and coverage gaps.
• Understanding that 50-70% of code at Duetto is AI-generated and QE practices must account for this.
• Experience prompting AI tools effectively for test migration tasks at scale.

Personal qualities

• Coaching mindset: you see your job as making developers better at testing, not gatekeeping.
• Comfortable operating with ambiguity — this function is built from scratch.
• Strong written and verbal communication skills for distributed teams.
• Able to prioritize pragmatically: knows the difference between value-add improvements and overhead.
• High standards for your own work combined with patience for teams building testing skills.

Technical environment

• End-to-end testing: Playwright, Selenium (legacy), Cypress (legacy).
• Unit testing: JUnit 5 + Mockito (Java), Jest + React Testing Library (TypeScript).
• Integration testing: Testcontainers.
• Contract testing: Pact.
• Performance testing: k6.
• Security: Snyk, Trivy.
• Mutation testing: PIT (Java), Stryker (JavaScript).
• CI/CD: GitHub Actions.
• Observability: DataDog, OpenTelemetry.
• AI tools: Claude Code, CodeRabbit, Augment.
• Core stack: Java, Spring Boot, React, TypeScript, Next.js, GraphQL, MongoDB, AWS.

Benefits

• Compensation range (L5 - senior): TBD.
• Equity participation.
• Comprehensive health, dental, and vision coverage.
• Flexible remote-first work environment.
• Home office stipend.
• Professional development budget.
• Unlimited PTO.

Why join Duetto now?

• Build from scratch. This is the first senior QE hire defining quality engineering practices for the entire engineering organization.
• Architectural impact at scale. The monolith-to-microservices migration is underway. The infrastructure you design shapes how the organization tests distributed systems for years.
• AI-first testing. Pioneer AI-assisted test generation in a codebase where 50-70% of code is already AI-generated.
• Modern tooling throughout. Playwright, Testcontainers, Pact, k6, GitHub Actions, DataDog — no legacy constraints.
• Clear growth path. Senior QE (L5) to staff/lead QE (L6) as the function matures.
• Stability and market leadership. Duetto is series D funded and the market leader in hospitality revenue management SaaS.
