Job description

About the Role An early-stage AI-native procurement SaaS startup based in Berlin is looking for a Founding Engineer to join its founding product team. You'll help build an AI-first platform that connects procurement and category managers to real-time supplier data and enterprise systems. This is a high-ownership, high-impact role: you'll shape the product, the architecture, and the engineering culture from the ground up - shipping daily and iterating directly with customers. This is an on-site role in Berlin. No visa sponsorship is available - candidates must be eligible to work in Germany without employer sponsorship. What You'll Do • Own core product areas end-to-end, from AI agent orchestration to the interfaces that category managers use daily. • Design reliable LLM workflows with evaluation loops, guardrails, and observability that hold up in production. • Build real-time supplier data pipelines, normalization layers, and integrations with enterprise ERP systems. • Ship to production continuously and collaborate directly with customers to iterate based on real feedback. • Make architectural decisions across the full stack, balancing performance, security, and developer experience. • Define engineering culture, tooling, and processes as the team grows. • Contribute to the product roadmap and work closely with founders on major technical decisions. • Mentor teammates and grow into an engineering leadership path as the company scales. What We're Looking For Required skills & experience: • Strong full-stack foundation with attention to both interfaces and back-ends, and the seam between them. • Proficiency in TypeScript (front-end and back-end) and Python; experience with Next.js and modern APIs. • Hands-on experience building SaaS products end-to-end in a startup environment. • Hands-on experience with LLMs, retrieval, and embeddings, including trade-off reasoning around latency, cost, and quality. • Proven ability to design and operate production-grade AI/ML workflows with monitoring and safety guardrails. • Experience building data pipelines, normalization, and integrations with enterprise systems. • Domain knowledge in ERP, procurement, or related enterprise software. • Strong written and verbal communication skills; comfortable working directly with customers and cross-functional teams. • Ownership mindset - thrives in ambiguity, defines what to build as well as how to build it, and defaults to shipping and learning fast. Nice to have: • Specific experience in procurement technology or supply chain platforms. • Background in founding-team or seed-stage environments. Location • Berlin, Germany - on-site • Visa sponsorship is not available; applicants must have existing eligibility to work in Germany. Find Jobs in Germany on Arbeitnow
