Résumé du poste

Collibra in Brussels is seeking a Senior AI Engineer to own end-to-end delivery of Unstructured AI systems, shaping how context is retrieved, structured, and used in production. You’ll build scalable backends and document-processing pipelines ingesting data from SharePoint, Salesforce, and internal APIs.

The role emphasizes hands-on Python, LLM-based enrichment, and production-grade services with Spark. You’ll collaborate across teams, maintain quality, design robust APIs, and occasionally

Qualifications

• Strong Python skills for data processing and API development.
• Experience with LLM-based enrichment and AI-driven models.
• Production experience with big data frameworks like Spark.
• Shipped production services, not notebooks.
• Bachelor’s degree or equivalent experience.
• Authorized to work in Brussels.

Responsabilités

• Own end-to-end delivery of Unstructured AI features from prototype to production.
• Build/scale document-processing systems for large-scale data.
• Integrate data from enterprise sources to provide context for AI features.
• Collaborate with engineering, product, and sales to rollout.
• Occasionally work with modern frontend development.

Description du poste

Joining Collibra’s Unstructured AI Team

• Work at the forefront of context engineering - shaping how AI systems retrieve, structure, and leverage context to deliver accurate, high-quality results at scale.
• Own end-to-end technical delivery of Unstructured AI systems - from feature prototype to stable production across enterprise environments.
• Build and scale full-stack systems that ingest, process, and enrich large volumes of unstructured content from distributed enterprise silos (PDFs, contracts, reports, and other document types).
• Collaborate with the Best: Work closely with xYC Founders to understand complex business challenges and deliver Deasy to solve them. Be part of a dynamic team where ideas flow freely and creativity thrives.
• Learn and Lead: Stay ahead of the curve by engaging with the latest developments in machine learning and AI. Share knowledge and lead by example to maintain high building standards.

This is a hybrid role based in our Brussels office. Our hybrid model means you’ll work from the office at least two days each week. This setup helps us stay connected, work more closely together, and keep making progress as a team.

Senior AI Engineer at Collibra are responsible for

• Shipping complex systems under real ambiguity — often defining the scope and acceptance criteria yourself, not receiving them.
• Writing and reviewing production-grade backend code (Python, FastAPI) — you write the services you design, rather than handing implementation to someone else.
• Building/deploying document-processing systems that handle large-scale, unstructured data environments.
• Integrating data from diverse enterprise data sources (e.g., SharePoint, Salesforce, or internal APIs) to provide context for AI features.
• Partnering across engineering, product, and sales teams, ensuring alignment from prototype to rollout.
• Occasionally working with modern frontend development.

You have

• Strong proficiency in Python (data processing, API development, and integrations).
• Hands-on work with LLM-based and AI-driven enrichment models (e.g., classification, entity extraction, deduplication, PII detection).
• Production experience with Spark or comparable big data frameworks — you've tuned and debugged jobs at real scale, not just written ones that worked on sample data.
• Experience shipping tested, reviewed production services rather than notebooks — and the discipline to hold that line when a coding agent writes the first draft.
• A track record of starting things: a specific example where you took a vaguely-scoped problem, defined the MVP yourself, wrote down your assumptions, and shipped it — without a PM converting it into tickets first.
• Solid understanding of data pipelines, microservice architecture, and API design.
• Experience ingesting and processing data from third-party enterprise sources (e.g., SharePoint/OneDrive, Salesforce, and SaaS-based knowledge bases).
• Familiarity with metadata systems, data cataloging, or document AI workflows.
• Knowledge of model evaluation best practices.
• Experience with search relevance.
• A bachelor’s degree or equivalent related working experience is required.
• Agentic engineering in practice, not just tool usage: you can say where an agent loop earns its keep, what guardrails and structured outputs keep it in bounds, and how you manage its context. Same discipline when coding agents write for you — tests, review gates, repo conventions.
• You must have work authorization to work in Brussels.

You Are

• Calm, structured decision-making under tight timelines or ambiguity.
• Capable of communicating clearly across engineering, product, and field teams, ensuring alignment from prototype to rollout.
• Experienced in spotting risks early and course-correcting without friction when delivery timelines are tight.
• Someone who cares deeply about data quality, precision, and governance.
• Strong communication and stakeholder-management skills across technical and business teams.

Measures of Success

• Within your first month, you will develop a deep understanding of our product vision and the unstructured data stack that powers it, shipping your first set of end-to-end features.
• Within your third month, you will take full ownership of technical delivery for key product areas, building robust capabilities that handle complex document processing and ensure a stable, high-performance experience for users interacting with diverse data sources.
• Within your sixth month, you will drive the development of ambitious, enterprise-grade AI product features that solve for data at scale, architecting the high-performance pipelines and advanced context engineering required to deliver accurate, reliable results.
