Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Agent Platform Engineer - **Company:** Proxima Fusion - **Location:** München, Germany - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Audit Trail, Continuous Integration, Python (Programming Language), Scientific Computating, Software Engineering, Google Cloud, High Performance Computing, Large Language Models, Multi-Agent Systems, Backend, Kubernetes, Free and Open-Source Software, Virtual Agents, Terraform - **Published:** August 27, 2026 - **Apply:** https://www.adzuna.de/details/5857154797 ## About the Role * You have 5+ years of software engineering experience, with real depth in Python and distributed backend systems * You have architected, built, and operated production-grade agentic or LLM systems well beyond the prototype phase * You know the current agent ecosystem hands-on: MCP, agent SDKs and CLIs, multi-agent orchestration patterns, sandboxed code execution and have formed opinions on where the abstractions should sit * You have run production workloads on Kubernetes and a major cloud (ideally GCP), and know what it takes to keep stateful, long-running services alive * You treat evaluation and observability as platform features, not afterthoughts * You take security seriously as a design constraint * You think in platforms and internal products * You are a low-ego, high-clarity communicator who can work directly with expert users and build consensus across teams * You have experience with infrastructure as code (Terraform) and CI/CD Nice to have * Experience with model gateways and routing * Exposure to scientific or high-performance computing: batch schedulers, HPC clusters, or simulation-heavy environments * Open-source contributions to AI/agent tooling * A track record of technical mentorship INTERVIEW PROCESS * Recruiter Interview (30-60 min) * Technical Screening (30 min) * Technical Panel (3x60 min) * CEO call (30min) ## Description * You will get to work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world. * You'll get to join and learn from an exceptional selection of accomplished and driven individuals. * Do your life's best work and enjoy the journey. * Get to show that big things are possible in Europe when you assemble the best talent. YOUR IMPACT * Technical owner of Proxima's AI agent platform, turning autonomous agents into reliable everyday colleagues for physicists and engineers. * Own the platform architecture, technical delivery, and day-to-day operation. * Scale the platform from an early product into reliable, governed infrastructure used across the company. * Enable agents to work across knowledge bases, write code, run simulations, and support engineering workflows. * Work within the Enterprise AI Team Lead's overall vision while owning how that vision is technically implemented. * Use strong technical judgment to influence and shape the platform roadmap. * Identify and propose new platform features based on hands-on experience and feedback from internal users. * Build a platform that engineers and scientists can trust for real, production-level work. WHAT YOU WILL DO * Own the design, delivery, and operation of our agent platform: the runtime and its primitives: durable sessions, sandboxed execution environments, long-running task execution, memory, and tool integration * Turn a rapidly evolving agent ecosystem into stable platform building blocks: evaluate harnesses, models, and protocols as they emerge, and decide what becomes a supported primitive versus a passing experiment * Co-Design the integration layer that connects agents to internal and external systems, from enterprise tools to our scientific computing stack, and the standards for how tools, skills, and context are exposed to agents * Make autonomy safe and governable: permission and approval flows with human-in-the-loop escalation, capability boundaries, audit logging, cost and token controls, and hardening against prompt injection and tool abuse * Build the evaluation and observability layer for non-deterministic systems: session tracing, quality evals, and cost/latency visibility, so we know agents work before our users have to find out * Operate what you build on Google Cloud with production discipline: reliability, failure handling, and observability * Work directly with demanding technical users and feed their feedback and your technical judgment into the platform roadmap you shape together with the team lead ## Related Videos - [On a Secret Mission: Developing AI Agents](https://www.wearedevelopers.com/videos/1510-on-a-secret-mission-developing-ai-agents) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Infrastructure as Code: The Developer's Secret Weapon](https://www.wearedevelopers.com/videos/1221-infrastructure-as-code-the-developer-s-secret-weapon) - [Understanding Kubernetes in a visual way](https://www.wearedevelopers.com/videos/100085-understanding-kubernetes-in-a-visual-way) - [The Agent Interface Layer: Protocols, Tools and Trust Boundaries](https://www.wearedevelopers.com/videos/100132-the-agent-interface-layer-protocols-tools-and-trust-boundaries) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care) - [From Prototype to Production: Build AI Agents with This Free 4-Course Learning Path](https://www.wearedevelopers.com/magazine/655-from-prototype-to-production-build-ai-agents-with-this-free-4-course-learning-path) - [A 5-Step Open-Source Setup for Agentic Engineering](https://www.wearedevelopers.com/magazine/738-a-5-step-open-source-setup-for-agentic-engineering) - [Graph and AI Trends 2026: Why Is AI Running but Not Yet Delivering?](https://www.wearedevelopers.com/magazine/680-graph-and-ai-trends-2026-why-is-ai-running-but-not-yet-delivering) - [Everything a Developer Needs to Know About MCP with Neo4j](https://www.wearedevelopers.com/magazine/604-everything-a-developer-needs-to-know-about-mcp-with-neo4j) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding)
