qa automation engineer @ thessaloniki | tax technology consulting

As a Consultant in our Tax Technology Consulting team, you will serve as the QA Automation Engineer for our AI platform used across professional services.

The platform consists of an Angular/TypeScript frontend, a Python backend with REST and streaming APIs, and AI features built on large language models and agent workflows. Releases are frequent, and reliability is a key priority.

You will build and own the automated testing strategy: UI and API test suites, regression coverage, and quality gates in the CI/CD pipeline. You will work closely with developers to catch issues early and to make every release predictable.

You will work on a production AI platform used by professionals across multiple countries, with direct influence on how quality is built into the product.

#KeyResponsibilities

• Design, build, and maintain automated UI tests for the Angular application

• Design, build, and maintain automated API and integration tests for the Python backend

• Integrate automated test suites into CI/CD pipelines as quality gates for pull requests and releases

• Establish and grow regression coverage for critical user journeys and platform features

• Define test strategy, test data, and test environments together with the development team

• Test AI-enabled features, including non-deterministic outputs, streaming responses, and tool or agent flows

• Investigate failures and flaky tests, identify root causes, and report defects clearly

• Include accessibility, performance, and basic security checks in the testing approach where appropriate

• Track quality metrics and report on release readiness

• Document test approaches and coach developers on testability and testing practices

#RequiredSkills

To qualify for the role, you must have:

• Bachelor’s degree in Computer Science, Software Engineering, or a related field

• 2–4 years of experience in test automation or QA engineering

• Hands-on experience with a modern UI automation framework such as Playwright, Cypress, or Selenium

• Experience with API testing and automation (pytest, Postman, REST clients, or equivalent)

• Programming proficiency in Python and/or TypeScript

• Experience running automated tests in CI/CD pipelines (GitHub Actions, Azure DevOps Pipelines, or equivalent)

• Solid understanding of testing fundamentals: test design, regression, test data management, and defect lifecycle

• Experience with Git and collaborative development workflows

• Excellent written and verbal communication skills in English

#PreferredSkills

• Experience testing Angular or other single page applications

• Experience testing real-time features such as SSE or WebSockets

• Experience testing or evaluating LLM-based or AI-enabled applications
