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

Gain exposure to cutting-edge technologies in cloud communications.
Be part of an internationally diverse company with a strong culture.
