AI Engineer (m/f/d)

Join Natuvion GmbH as an AI Engineer to build impactful AI systems in a remote position, utilizing Go and Python for enterprise data solutions.

• Design, build, and operate RAG solutions across the full spectrum — from semantic search through to retrieval over highly structured data and knowledge graphs
• Build agentic systems that perform multi-step tasks reliably and safely against enterprise data
• Drive automation of internal processes with AI, and ship AI features into customer-facing products
• Own retrieval quality end to end: chunking and embedding strategies, hybrid and re-ranking approaches, and the evaluation that proves it works
• Evaluate and recommend the tooling for our AI stack — vector stores, orchestration, retrieval frameworks, model choices — and drive those decisions together with our architect. We expect informed proposals, not a wait for instructions
• Author production services in Go (gRPC) and integrate them with our AI router and existing platform; prototype and iterate in Python
• Make grounded technical decisions — retrieval vs. fine-tuning vs. prompting vs. a classical approach — and defend the trade-offs in architectural reviews
• You hold a degree in Business Informatics or Computer Science
• You have several years of experience, a strong Python proficiency for AI development, and genuine comfort working in Go — you're 100% willing and able to author production gRPC services, not just call them
• A proven track record of building AI features on enterprise data that actually shipped and stayed in production
• Real understanding of the fundamentals behind modern RAG: embeddings and vector similarity, retrieval and ranking, and how transformer-based models behave. You reason about why a pipeline succeeds or fails — you don't guess
• Hands-on experience designing and evaluating retrieval and agentic systems, including building your own metrics and eval rather than trusting vibes
• Experience with knowledge graphs or structured/semantic data representations is a strong plus
• Curiosity that shows: ideally you've fine-tuned a small model yourself (LoRA / QLoRA or similar) and understand the basics of what's happening under the hood
• You stay genuinely current in a fast-moving field and hold reasoned opinions. You can walk into a discussion with our architect with a concrete recommendation and defend the trade-offs — and change your mind when the evidence says so
• Comfortable in cloud-native environments — you think about observability, failure modes, and cost as first-class concerns
• Professional working proficiency in English — you can explain complex technical ideas clearly to peers and stakeholders

• Home office contracts & absolute flexibility through free organization of working hours
• Permanent position and 30 days of vacation
• FlexWork: Work remotely from other European countries for up to 3 months per year
• Monthly budget for individually selectable benefits from over 50 possible offers via emplu, various offers via corporate benefits, as well as bicycle and car leasing via salary conversion
• Mental Health Benefit 'Nilo' – 10 free sessions with psychologists annually as well as access to meditations and courses
• We provide you with targeted support in your professional and personal development at Natuvion
• Mentoring program for a structured and personal induction
• Be part of the #teamgreen - At Natuvion, you'll work on innovative projects as part of a team that stands up for each other. We rely on cooperation, openness and trust
• Modern equipment and central offices in Walldorf, Berlin, Munich and Leipzig
• Your long-term perspective is important to us, which is why we subsidize your company pension scheme as well as capital-forming benefits

• degree in Business Informatics or Computer Science
