Job Description

Hi, I'm Rita Dias , your Recruiter and we are excited to learn more about you and your unique background.

The Software Development Engineer in Test (SDET) is a software engineer who builds and owns the automated test systems, frameworks, and infrastructure that make fast, confident releases possible.

What You will Do:

• Design, build, and maintain the automated test suite and test infrastructure as production software:
• unit and component test guidance (with developers)
• API and service-level / integration tests
• end-to-end and UI tests
• contract tests for integrations
• Apply the same software engineering discipline to test code as to product code: code review, modular architecture, versioning, and documentation
• Act as the testing expert in defining the strategy for each product, together with the Tech Lead
• Integrate tests into the pipeline so they run automatically on every change
• Develop approaches for testing non-deterministic behavior:
• – conversational AI flows and intent handling
• – LLM/speech-based components (evaluation sets, regression baselines, tolerance-based assertions)
• Contribute directly to the product codebase where testability, instrumentation, or observability hooks are needed, rather than only requesting them
• Develop, own, and continuously improve the QA-related AI workflows, skills, and agents that plug into that practice
• Use AI coding assistants as a normal part of daily work to accelerate delivery:
• – generating and refactoring test code
• – expanding coverage across similar cases and edge conditions
• – migrating and consolidating legacy tests
• – producing test data and fixtures
• – triaging failures and summarizing root causes
• Cover non-functional aspects through automated tooling: performance and load on real-time paths, basic security testing, accessibility of Smartflow UIs

We are looking for candidates with:

• At least 5 years experience in a QA automation role
• Software engineering fundamentals, data structures, algorithms, and system design held to the same bar as a Software Engineer, applied to test system
• Strong programming ability
• – TypeScript / JavaScript
• – comfortable reading and navigating application code (Node.js, React/Vue)
• Proven experience building an automated test suite from a low or fragmented baseline, and consolidating inconsistent existing tests
• Modern test automation frameworks experience (e.g. Playwright, Cypress, Vitest/Jest, or equivalents)
• API testing and integration testing, including test data and mocking strategies experience
• Experience with CI/CD pipelines and integrating automated tests into them (e.g. Azure DevOps, GitHub Actions)
• Hands-on with AI coding assistants (e.g. Claude, Copilot, Cursor) in real delivery work

What we offer you...

• Work with a talented and passionate teams of like minded professionals.
• Gain exposure to cutting-edge technologies in cloud communications.
• Be part of an internationally diverse company with a strong culture.
• 25 vacation days plus your birthday off
• Health insurance and life insurance
• Meal allowance of €10.46/day
• Home office allowance
• Hybrid working: 2 days per week in the office
