Founding Engineer

opusFounding EngineerBerlin, Germany (hybrid)EmployeeSoftware Developmentbuild for those who build 🏭opus builds the platform to deploy AI agents across industrial supply chain operations. Our mission is to strengthen Europe's industrial backbone by making operational processes future-proof. The agents automate the purchase order lifecycle end to end, giving companies control over their single largest cost driver. They run on the supply chain context graph: a real-time intelligence layer built from ERP data and the knowledge that today only lives in inboxes and people's heads. That graph is where the value sits, and it carries agent use cases far beyond procurement. Leading companies already trust opus AI agents and are transforming their processes into a competitive advantage with us.🚀 we are in production with enterprise customers – scaling rapidly and shipping new features as we speak.💰 we secured $6M in funding from Project A, Speedinvest, Sequoia Scouts and industry veterans like Marcell Vollmer (former Chief Digital Officer & Chief Procurement Officer of SAP).👥 we are a team of entrepreneurs, industry experts, and engineers driven by a joint ambition – to safeguard the economic foundation of Europe for future generations.Tasks🎯 Your impactOwn the 0-to-1 Journey – Architect and ship new features from first principles. You will be the primary builder of systems where no blueprint exists, ensuring every line of code balances immediate impact with long-term scalabilityBuild Effective Agentic Solutions – Design agents that utilize LLMs for reasoning, document extraction, and the end-to-end automation of complex enterprise processes. You will implement AI best practices to ensure our autonomous agents act with precision, security and industrial-grade reliabilityArchitect Enterprise-Ready Systems – You will design mission-critical, secure, and resilient AI solutions. Your work will be held to the highest reliability standards to ensure data integrity and security for global industrial leadersExecute Across the Stack – You will take full ownership of the user journey. Whether it's refining the React frontend, architecting complex backend logic, or managing cloud infrastructure, you do whatever it takes to ship high-quality, end-to-end featuresRequirements🌟 What makes you a great fitLanguages and Frameworks – You have worked in Python and frameworks like FastAPI, Pydantic, SQLAlchemy. You are familiar with TypeScript and frontend libraries like React and are able to build intuitive interfaces for complex workflowsAI and LLMs – You have practical experience with prompt engineering and agentic frameworks (e.g. Google Agent Development Kit, LangGraph). You may even have production experience with LLM observability and evaluationMost importantly, you are a fast learner who is eager to learn any technology required to solve the problem at handHigh Agency – You see a critical problem outside your immediate scope, like an infrastructure bottleneck or a customer friction point, and you fix it without being asked, exercising good judgment while doing soPragmatic & Fast – You value "good enough to ship" over "perfectly engineered.” You use AI assistants (e.g. Cursor, Copilot, Gemini) to automate the mundane so you can focus on the highest-value tasksNice-to-Have’s – German Language Proficiency – While English is our primary language, German fluency is a strong plus to help us better support our core industrial customer baseBenefits📦 The opus packageCompetitive compensation + meaningful equity – real ownership in opus’ long-term successImpact from day one – high ownership, fast customer feedback, responsibility for outcomesAI-first, builder environment – the best tools, low overhead, strong bias to ship and learnIn-person by design – Berlin-Mitte office, high focus, ambitious team, low ego28 vacation days & flexibility when you need to recharge🧑‍🚀 Our interview processPhone Screen (30 min) - Quick intro to align on the role, your...
