We combine first-principles thinking with cutting-edge technology to build a radically better energy system.\nWe've raised over $200M from top-tier investors including Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, 20VC, Hummingbird and Collaborative Fund, alongside strategic angels including Nico Rosberg and GPs behind Meta, Revolut, Spotify and Uber.\nWe're building a fully integrated energy company: developing our own solar, batteries and other generation projects, building our own hardware, improving and developing grid infrastructure, trading power in real time, using AI across the business, and installing distributed energy in homes. By selling directly to consumers we cut out the middleman, lower costs and pass the savings on to our customers.\nWe’re building a cutting-edge AI team. As an Applied AI Engineer, this role suits someone who is specifically interested in applied AI and how it can improve the energy experience for our customers and our internal operations.\nYou’ll work on consumer features (using VLM and LLM tools), and build AI tools and agents that make teams across Fuse more productive, from customer support to warehouses and back office. This is an applied engineering role, not pure research: you’ll own what you build, from spec to production.\nResponsibilities\nShip AI features for customers, such as personalised energy recommendations and onboarding from an energy bill.\nBuild LLM applications and agents for support, engineering, warehouse and back-office teams, including multi-agent systems and durable workflows (e.g. Temporal).\nBuild the engineering around them: cloud infrastructure, integrations, and access control so users and agents only reach what they should.\nOwn evaluation: datasets, golden answers, human and LLM judges, A/B tests. Know whether a change genuinely helped.\nChoose models by performance, latency and cost, and revisit as models improve.\nWork with trading, operations and backend teams so models reflect real-time market conditions, energy pricing and demand and weather forecasts.\nMonitor AI systems in production and keep them reliable.\nRequirements\n3+ years of experience, with requirements varying by role level.\nExperience owning an applied AI system end to end, ideally in a startup or small team, and able to explain what broke and how you knew it worked.\nA software engineer who moved into applied AI, or an ML engineer who writes production code. We value both.\nStrong Python (or similar) and experience deploying LLMs or VLMs into production.\nSolid understanding of cloud technologies, containerisation and scalable AI applications.\nAnalytical, rigorous and quick to learn. You don’t need our exact tools, just the ability to pick them up.\nBonus: PyTorch or TensorFlow; forecasting, weather and demand modelling; energy markets and trading; fine-tuning or RL; vision, document or NLP pipelines; agent runtimes and MCP.\nBenefits\nCompetitive salary and eligibility for equity\nBiannual bonus scheme\nFully expensed tech to match your needs\nPrivate health insurance\nBreakfast and dinner allowance for office-based employees\nAs we hire globally, benefits may vary by location.","description_format":"text","description_chars":3252,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Health insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Germany","iso":"DE","kind":"country"},{"name":"United Arab Emirates","iso":"AE","kind":"country"},{"name":"United Kingdom","iso":"GB","kind":"country"},{"name":"Switzerland","iso":"CH","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy & Utilities","Solar Energy","Wind Energy","Ride Hailing"],"lifecycle":[{"event":"open","at":"2026-11-04T19:42:37Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":67,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-11-08T05:47:12Z"},"pay":null,"html_url":"https://alion.io/job/fuse-energy-applied-ai-engineer-2","json_url":"https://alion.io/job/fuse-energy-applied-ai-engineer-2.json","meta":{"generated_at":"2026-11-09T01:35:27Z","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":3370,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":3017},"rest":"https://alion.io/mcp/rest/get_company?id=3017"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffuse-energy-applied-ai-engineer-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Ffuse-energy-applied-ai-engineer-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Ffuse-energy-applied-ai-engineer-2"},{"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/fuse-energy-applied-ai-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffuse-energy-applied-ai-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3764891}},{"tool":"search_jobs","arguments":{"company":"fuseenergy.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3764891},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
