Software Engineer SDET

About the Role: We are looking for a skilled Software Development Engineer in Test (SDET) to join our team. This is a hands-on role for a software engineer who is passionate about quality, with a strong focus on building test automation into the development workflow — not bolting it on after the fact. You'll work as an embedded member of a development squad, writing tests alongside production code and owning the reliability of what you ship. You'll combine an engineer's mindset with a deep focus on quality, leveraging the power of Generative AI to enhance our QA workflows.

What You'll Be Doing

• Design and build automated tests, including unit and integration tests, directly within our core codebase using .NET/C# or Java.

• Enhance and maintain our separate UI automation framework, which is built with Playwright and TypeScript.

• Write and maintain tests at multiple levels of the testing pyramid (unit, integration, contract, E2E) with a bias toward lower-level, faster-running tests.

• Use Testcontainers or Docker Compose to create isolated, on-demand test environments — no dependence on shared staging infrastructure.

• Design and maintain test data strategies for a microservices environment — including isolated data setup, deterministic seeding, and reliable teardown — so tests are independent, repeatable, and never pollute shared environments.

• Build and maintain test fixture libraries that provision and clean up across multiple databases and services, ensuring each test run starts from a known state.

• Leverage containerization technologies like Docker to create robust, reproducible test environments that eliminate dependencies on shared infrastructure.

• Actively leverage Generative AI tools to radically transform QA workflows, from generating test cases and data to optimizing automation scripts and creating comprehensive test reports.

• Collaborate with cross-functional teams to understand software requirements and develop comprehensive automation test plans.

• Integrate automated test suites into our CI/CD pipelines to ensure seamless and continuous quality checks.

• Identify and report defects with detailed steps to reproduce, and participate in code reviews to ensure high-quality software.

• Stay current with industry trends in QA, automation, and AI-powered testing solutions.

• Pipeline Health: Own the reliability of the CI/CD pipeline for your squad, ensuring that a red build means a real bug, not a timeout or environment issue.

What We're Looking For

• Bachelor's degree in Computer Science, Engineering, or a related field.

• 3+ years of professional software engineering experience with a focus on testability and quality engineering.

• Strong programming skills in .NET/C# or Java.

• Experience with Playwright and TypeScript/JavaScript for web UI automation.

• Ability to read, write, and review production code — not just test scripts in a separate repo.

• Experience writing automated API tests in code (REST Assured, HttpClient, or Playwright API testing) — not just manual exploration with GUI tools.

• Experience writing unit and integration tests as part of the development workflow (NUnit, xUnit, JUnit 5).

• Experience with Testcontainers or similar tools for provisioning real services (databases, message brokers) during test execution.

• Experience designing test data management strategies for multi-database, microservices architectures — including data isolation, factory-based data generation (e.g., Builder patterns, Bogus/.NET, Faker), and per-test cleanup.

• Understanding of database transaction rollback strategies, schema-aware test seeding, and environment teardown patterns that prevent data mutation across test runs.

• Hands-on experience configuring and maintaining CI/CD pipelines (GitHub Actions, Azure DevOps, or Jenkins), including test parallelization and pipeline reliability.

• Understanding of contract testing concepts (Pact) for microservices integration.

• Familiarity with software design patterns and principles (SOLID, dependency injection) that enable testable architectures.

• Experience with containerization, particularly Docker, and using it for test automation.

• Demonstrated experience using AI coding assistants (GitHub Copilot, Claude) for test generation, debugging, and code review, with a passion for exploring new AI-driven QA solutions.

• Experience testing cloud-based or distributed systems.

• Proficient with Git workflows (branching, rebasing, code reviews) as a daily part of the development process.

• Experience working as an embedded member of a development squad, not a separate QA team.

Nice to Have

• Experience with cloud-based testing solutions (e.g., BrowserStack).

• Experience with code-first performance testing using Grafana k6 or Locust, integrated into CI pipelines.

• Understanding of the eCommerce domain.

• Experience with chaos engineering or resilience testing.

• Familiarity with observability tools (application logs, distributed tracing, APM) for debugging test failures in context.

• Experience with synthetic test data generation tools or frameworks.

• Familiarity with database migration tools (Flyway, Liquibase) in the context of test environment provisioning.
