At TBAuctions, we are building the intelligent auction platform behind our brands, with machine learning and AI at its core: powering recommendations, search and personalization, valuation, supply-demand matching and streamlining processes with AI agents across millions of auctions.

What you will do

Build and architect

• Own the architecture of our ML & AI systems end to end: data pipelines, feature and model stores, training and serving infrastructure, built as reusable capabilities our auction brands can share.

• Design the architecture and orchestration of our AI agents platform, with strong evaluation, monitoring and guardrails for reliable behaviour in production.

• Strengthen and contribute to our existing MLOps setup: automated training, validation, deployment and monitoring, experiment tracking and CI/CD.

• Design and build our recommendation, search and ranking systems end to end: candidate generation and retrieval, ranking models, embeddings and vector search, and real-time personalization at scale.

• Deploy models as robust APIs and scalable microservices, containerized and orchestrated with Kubernetes.

• Design systems, write and review code in a modern stack, and raise the bar on engineering best practices.

What you bring

• 7+ years in ML engineering, including 2 years leading technical direction of teams (formal people management is a plus).

• Master’s in Computer Science, Statistics, Mathematics, or a related field.

• Experience with recommender systems at scale: retrieval and candidate generation, ranking models, and real-time personalization in high-load production environments.

• A track record of building and operating ML/AI systems in production, across the full lifecycle: feature engineering, model development, deployment and monitoring.

• Strong systems, architecture and MLOps background: distributed, event-driven ML systems, API and model serving as microservices, containerization and orchestration with Kubernetes / AKS, and CI/CD and experiment tracking.

• Strong grounding in experimentation and statistics: metric design, A/B testing and causal inference to quantify business impact.

• Expertise in Python and PySpark, with a solid grasp of ML algorithms and frameworks (MLlib, Scikit-learn, TensorFlow/PyTorch, MLflow). Familiarity with a language such as Java or Kotlin is a plus.

• Experience in building AI agents and LLM-based products in production, including memory, context engineering, retrieval and orchestration, and multimodal retrieval systems/architecture.

• Comfortable splitting your time between building directly and leading, and happy to stay hands-on in the code and architecture.

• Excellent communication skills, able to explain complex technical choices and trade-offs to non-technical stakeholders.

What we offer you

• A hands-on leadership role with real ownership, within an entrepreneurial and innovative organization

• A modern data stack (FastAPI, Databricks, Airflow, DBT) and cloud-native deployment on Azure with Kubernetes (AKS).Independent and varied role within an entrepreneurial and innovative organization

• Gross yearly salary of € 100.000 - € 120.000 (including holiday allowance), depending on experience

• Bonus scheme

• Pension scheme

• 25 vacation days

• Laptop and iPhone

• Training opportunities

• Working in a team of professionals, where hard work is well combined with humor
