This is a&nbsp;backend-heavy fullstack role&nbsp;where you will be responsible for more than just simple prompt engineering. You will be architecting&nbsp;Agentic Workflows—systems that can reason, use tools, and execute complex coding tasks autonomously.
&nbsp;
The ideal candidate is a language-agnostic engineer who is obsessed with the&nbsp;Claude&nbsp;ecosystem and has hands-on experience building systems where AI agents interact with real-world data and codebases.

<li>Mastery of the Claude 3/3.5 family. You understand how to leverage Claude’s high reasoning capabilities and long context windows for complex logic.</li>
<li>Experience building "AI-coding" features—using LLMs to generate, refactor, and test code programmatically within an application.</li>
<li>Strong proficiency in at least one major backend language (Python, C#, or JavaScript/Node.js) and the ability to design the infrastructure (APIs, Webhooks, Databases) that supports AI agents.</li>
<li>While backend-heavy, you are comfortable building the necessary frontend components (React/Vue) to allow users to interact with AI agents seamlessly.</li>
<li>Extensive experience giving LLMs "tools"—designing clean API interfaces that agents can call to perform actions in the physical or digital world.</li>
<li>Intermediate-advanced English level.</li>
<li>Time zone: CET (+/- 3 hours). We are unable to consider applications from candidates in other time zones.</li>
</ul>

<li>Experience with LangChain, LangGraph, or CrewAI.</li>
<li>Knowledge of Vector Databases (Pinecone, Weaviate) and advanced RAG patterns.</li>
<li>Familiarity with LLM Observability tools (LangSmith, Helicone) to debug agentic reasoning chains.</li>
<li>Background in Software Engineering Fundamentals: You treat AI code like production code (CI/CD, Unit Testing, Version Control).</li>
</ul>
&nbsp;
&nbsp;
<h4>Responsibilities:</h4>
&nbsp;
<ul>
<li>Design and deploy autonomous agents that can handle end-to-end tasks, specifically focusing on Claude-based coding agents.</li>
<li>Build the scalable "brains" of the application, ensuring that AI reasoning is integrated into the core business logic.</li>
<li>Refine system prompts and multi-shot examples to maximize Claude’s reasoning performance.</li>
<li>Implement guardrails and validation layers to ensure that agentic outputs are safe, predictable, and high-quality.</li>
<li>Work with Product and UX teams to define how "AI Agents" should feel and behave within the product interface.</li>

This is a long-term, full-time remote engagement, with the opportunity to work with cloud platforms, CI/CD pipelines, and modern tooling to build real products used globally.
