Founding Engineer

<p><strong>build for those who build</strong> 🏭</p>
<p>opus builds the <strong>platform to deploy AI agents across industrial supply chain operations.</strong> 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.</p>
<p>🚀 we are in production with <strong>enterprise customers</strong> <strong>–</strong> scaling rapidly and shipping new features as we speak.</p>
<p>💰 we secured <strong>$6M in funding</strong> from Project A, Speedinvest, Sequoia Scouts and industry veterans like Marcell Vollmer (former Chief Digital Officer & Chief Procurement Officer of SAP).</p>
<p>👥 we are a team of entrepreneurs, industry experts, and engineers driven by a joint ambition <strong>–</strong> to safeguard the <strong>economic foundation of Europe</strong> for future generations.</p>
<h2 id="tasks">Tasks</h2>
<p><strong>🎯 Your impact</strong></p>
<ul>
<li><strong>Own the 0-to-1 Journey</strong> – 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 scalability</li>
<li><strong>Build Effective Agentic Solutions</strong> – 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 reliability</li>
<li><strong>Architect Enterprise-Ready Systems</strong> – 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 leaders</li>
<li><strong>Execute Across the Stack</strong> – 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 features</li>
</ul>
<h2 id="requirements">Requirements</h2>
<p><strong>🌟 What makes you a great fit</strong></p>
<ul>
<li><strong>Languages and Frameworks</strong> – You have worked in <strong>Python</strong> and frameworks like <strong>FastAPI</strong>, Pydantic, SQLAlchemy. You are familiar with <strong>TypeScript</strong> and frontend libraries like <strong>React</strong> and are able to build intuitive interfaces for complex workflows</li>
<li><strong>AI and LLMs</strong> – You have practical experience with prompt engineering and agentic frameworks (e.g. PydanticAI, Google ADK, LangGraph). You may even have production experience with LLM observability and evaluation</li>
<li><strong>Most importantly</strong>, you are a fast learner who is eager to learn any technology required to solve the problem at hand</li>
<li><strong>High Agency</strong> – 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 so</li>
<li><strong>Pragmatic & Fast</strong> – 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 tasks</li>
<li><strong>Nice-to-Have’s</strong> – <strong>German Language Proficiency</strong> – While English is our primary language, German fluency is a strong plus to help us better support our core industrial customer base</li>
