Founding Engineer (Knowledge Graph / AI Systems)

We’re building context/fab, a venture-backed industrial AI startup on a mission to upgrade manufacturing by solving the hardest data problems on the shop floor.

As our Founding Engineer (Knowledge Graph / AI Systems), you’ll architect and build the intelligence layer that powers our platform - from graph-based RAG to agentic workflows to robust LLM evaluation pipelines. You’ll work directly with the founders to define how industrial knowledge is modelled, retrieved, reasoned over, and validated across real-world factory environments.

This is a deeply technical, high-ownership role for someone who wants to invent and ship the core AI systems behind a category-defining product.

What You’ll Do

• Design and build our industrial knowledge graph: schema, ontology, data modelling, ingestion, enrichment, and versioning
• Architect and implement graph-based RAG pipelines, retrieval strategies, and hybrid search
• Develop agentic workflows that orchestrate tools, models, and data sources across the manufacturing stack
• Build and maintain rigorous LLM evaluation, benchmarking, and performance testing methodologies
• Develop scalable Python systems for data transformation, embedding pipelines, prompt strategies, and model routing
• Work with real factory data - noisy, unstructured, multimodal - and turn it into structured context for reasoning
• Collaborate closely with fullstack/infrastructure/edge teams to integrate graph/RAG/agentic systems into production services
• Work with edge-connectivity and ingestion teams to model data flowing from real-time factory systems into the graph
• Prototype, experiment, and ship improvements to model quality, latency, reliability, and grounding
• Act as a true partner to the founders - defining our AI direction, research priorities, and technical strategy

Do you have experience in Rust (programming language)?, Do you have a Master’s degree?, * Strong experience in Python and building production-grade data/AI systems

• Experience with knowledge graphs (Neo4j, FalkorDB, or similar)
• Be product-minded and excited about deeply understanding customer problems without being spoon-fed requirements
• Deep familiarity with retrieval systems, embeddings, semantic search, or vector stores
• Experience with LLM evaluation, testing harnesses, model benchmarking, and reliability engineering
• Hands-on experience with RAG pipelines, prompt engineering, and agent frameworks is a big plus
• Comfort working with messy, heterogeneous real-world datasets
• Understanding of distributed systems, data modelling, or ETL/ELT pipelines
• Exposure to Go/Rust ecosystems is helpful
• Pragmatic: you care about shipped impact, not research for its own sake
• Entrepreneurial - you want to build foundational systems at the earliest stage of a company
• Fluent in English; German is a plus, * Bachelor’s or Master’s in Computer Science, Engineering, AI/ML, Data Science, or related field
• Strong communication and collaboration skills
• Comfortable working independently in a high-ambiguity, high-velocity environment

• Work directly with founders at the earliest stage of a startup
• Build at the intersection of AI, manufacturing, and data - solving problems with huge real-world impact
• Excited about building up deep tech capabilities to keep manufacturing competitive in Europe
• Shape our engineering culture in our Munich office
• Competitive salary and meaningful early equity
• Grow faster than anywhere else - experience a 10-year career in 2 years
