# Senior Test Automation Engineer - Data & AI Team \(m/f/d\) - Company: [Soficonv]() - Location: Zwijnaarde, East Flanders, Belgium - Team: Platform Delivery - PLD - Posted: August 17, 2026 ## Job description **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. * Fully covered private health insurance, so you can focus on what matters most. * 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?
