The posting

At SOFICO, we're building the future of mobility through Miles, our market-leading platform for leasing, fleet, and mobility operations worldwide. As an international team, we combine innovation, collaboration, and ownership to deliver real impact for our customers, in a culture of continuous learning, mutual support, and shared success.

From our office in Ghent, we are scaling our Data & AI organization, the team behind SOFICO AI Cloud and the Miles Enterprise Agentic Platform (AutoPilot & AutoRoute). Our platform combines AI, cloud-native technologies, and enterprise software, leveraging Java/Quarkus services, Python/LangGraph agents, Azure AI Foundry, Temporal workflows, and Langfuse observability.

As a Senior Test Automation Engineer, you will drive the quality and reliability of this platform by building and owning a robust test automation strategy across the entire AI ecosystem. Working closely with engineers across AI Runtime, Cloud Ops, API & Saga, Knowledge, Governance, and Data teams, you will ensure that critical business flows, integrations, and AI-powered capabilities are validated through scalable, automated testing.

What you’ll do...

Deterministic testing (classic, pass/fail quality gates)

  • Own and evolve the test automation strategy for the Data & AI platform — unit, integration, contract, regression, and end-to-end — designing, building, and maintaining automated frameworks and suites integrated into CI/CD pipelines.
  • Validate end-to-end business processes within sandboxed Miles environments, ensuring correctness, reliability, and safe failure handling.
  • Develop API and contract testing approaches for distributed services and integrations.

Non-deterministic testing (AI and agentic behavior)

  • Design and own evaluation approaches for AI-powered and agentic capabilities where outcomes are probabilistic rather than pass/fail: LLM-as-a-judge setups, baseline/benchmark datasets, and process/quality metrics for agent behavior.
  • Establish baselines and regression tracking for model and agent output quality over time, this alongside the deterministic CI gates.

Platform-wide

  • Collaborate across engineering domains to ensure platform-wide quality and release confidence.
  • Drive continuous improvement in test automation practices and tooling, and act as a mentor and quality advocate, helping teams adopt effective automated testing approaches.

What you bring...

We're looking for a strong overall profile, without expecting you will tick every box.

Please indicate in your application your current experience level (e.g. none / familiar / proficient / expert) for each of the areas below. This helps us understand your profile and have a more focused conversation.

  • Test automation engineering: unit/integration/e2e frameworks, CI/CD integration
  • Testing APIs, backend services, microservices, and distributed systems
  • Programming in Java and/or Python, including typed schemas, mocking, and test-data setup/teardown
  • Designing scalable automation frameworks from the ground up, and coaching others in their adoption
  • Non-deterministic / AI evaluation testing: LLM-as-a-judge, benchmarking, quality metrics for agentic systems (plus)
  • Workflow orchestration platforms, cloud-native applications, and LLM/agentic systems (plus)
  • Tooling such as Playwright, Kubernetes, and modern DevOps practices (advantage)

An analytical mindset, attention to detail, and a genuine drive to improve software quality matter as much as any single line above.

What's in it for you…

  • Competitive salary package.
  • Meal allowance provided per working day.
  • Group and hospitalisation insurance.
  • Hybrid working and flexible hours, giving you the freedom to shape your workday.
  • A modern co-working space offering a comfortable working environment.
  • A structured onboarding program from day one, with a dedicated coach to help you get up to speed and grow in your role.
  • Regular opportunities to connect beyond day-to-day work — casual drinks, team activities, and company-wide events.

Ready to build the secure and deterministic capabilities behind the next generation of mobility software? Join SOFICO and let's shape what's next together!

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
