Backed by over €650M and powered by a growing team across Munich, Zurich, and Oxford, we are developing the hardware and infrastructure needed to deliver the world’s first commercial stellarator fusion power plant.\nOur concept advances the most mature fusion technology out there, the Wendelstein 7-X stellarator, through two next-generation machines: Alpha and Stellaris. Our work combines stellarator optimization, advanced computation, machine learning, and high-temperature superconducting magnets to unlock higher-performance designs that were previously out of reach.\nTurning these designs into a functioning fusion power plant requires excellence and ownership across every discipline, from physics and engineering to software, manufacturing, law, and business functions.\nWHY JOIN PROXIMA FUSION\nYou will get to work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world.\n\nYou'll get to join and learn from an exceptional selection of accomplished and driven individuals.\n\nDo your life’s best work and enjoy the journey.\n\nGet to show that big things are possible in Europe when you assemble the best talent.\n\nYOUR IMPACT\nTechnical owner of Proxima’s AI agent platform, turning autonomous agents into reliable everyday colleagues for physicists and engineers.\n\nOwn the platform architecture, technical delivery, and day-to-day operation.\n\nScale the platform from an early product into reliable, governed infrastructure used across the company.\n\nEnable agents to work across knowledge bases, write code, run simulations, and support engineering workflows.\n\nWork within the Enterprise AI Team Lead’s overall vision while owning how that vision is technically implemented.\n\nUse strong technical judgment to influence and shape the platform roadmap.\n\nIdentify and propose new platform features based on hands-on experience and feedback from internal users.\n\nBuild a platform that engineers and scientists can trust for real, production-level work.\n\nWHAT YOU WILL DO\nOwn 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\n\nTurn 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\n\nCo-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\n\nMake 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\n\nBuild 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\n\nOperate what you build on Google Cloud with production discipline: reliability, failure handling, and observability\n\nWork directly with demanding technical users and feed their feedback and your technical judgment into the platform roadmap you shape together with the team lead\n\nWHO YOU ARE\nMust have\nYou have 5+ years of software engineering experience, with real depth in Python and distributed backend systems\n\nYou have architected, built, and operated production-grade agentic or LLM systems well beyond the prototype phase\n\nYou 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\n\nYou have run production workloads on Kubernetes and a major cloud (ideally GCP), and know what it takes to keep stateful, long-running services alive\n\nYou treat evaluation and observability as platform features, not afterthoughts\n\nYou take security seriously as a design constraint\n\nYou think in platforms and internal products\n\nYou are a low-ego, high-clarity communicator who can work directly with expert users and build consensus across teams\n\nYou have experience with infrastructure as code (Terraform) and CI/CD\n\nNice to have\nExperience with model gateways and routing\n\nExposure to scientific or high-performance computing: batch schedulers, HPC clusters, or simulation-heavy environments\n\nOpen-source contributions to AI/agent tooling\n\nA track record of technical mentorship\n\nINTERVIEW PROCESS\nRecruiter Interview (30-60 min)\n\nTechnical Screening (30 min)\n\nTechnical Panel (3x60 min)\n\nCEO call (30min)\n\n*This role sits at \"L3\" of our framework, please inquire during the recruitment process for further information.\nAt Proxima Fusion, our mission is bold: making limitless clean energy a reality. To get there, we need a high-performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose. We know that diversity of thought and experience leads to better ideas, stronger execution, and a more resilient team. We don’t look at how you identify, what you look like, who you choose to worship or what ethnicity you are. We care about what you can bring to the table.","description_format":"text","description_chars":5512,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Nuclear Energy"],"lifecycle":[{"event":"open","at":"2026-08-24T17:00:33Z"}],"visa":[],"liveness":{"score":74,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.823,"p_room":0.9,"age_days":53,"expected_fill_days":84,"reasons":["conf:3","velocity","win:mid"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/proximafusion-senior-agent-platform-engineer","json_url":"https://alion.io/job/proximafusion-senior-agent-platform-engineer.json","meta":{"generated_at":"2026-10-18T17:21:22Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":22533,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":8931},"rest":"https://alion.io/mcp/rest/get_company?id=8931"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fproximafusion-senior-agent-platform-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fproximafusion-senior-agent-platform-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fproximafusion-senior-agent-platform-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/proximafusion-senior-agent-platform-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fproximafusion-senior-agent-platform-engineer"}]}
