🧠 Founding AI Engineer – LLMs, Infra & Real-World Automation London (Onsite, Visa Sponsorship Available) | £ very competitive Salary + Significant Equity A stealth-mode startup in the AI x real-world automation space is on a mission to bring the speed of software to the physical world. From aerospace to energy to healthcare, critical industries are still reliant on outdated, manual processes. This company is building the AI backbone to modernize how real-world systems operate with production-grade LLMs, intelligent agents, and deep infra thinking at the core.
They're backed by elite investors (who’ve funded global platforms across software, AI, and logistics), with offices in London. Now they're hiring a founding engineer to build, scale, and own core systems from day one.
🔧 What You’ll Do

• Design and ship production-grade features using foundation models (text + multimodal)
• Build LLM-powered workflows using agents, tools, and custom function-calling logic
• Architect robust infrastructure for RAG, indexing, fine-tuning, and deployment
• Move across the stack: infra, backend, model orchestration, and even customer-facing tools
• Work closely with the founders to set engineering culture, shape the roadmap, and grow the team

🧠 What They’re Looking For

• 2+ years of experience building and shipping fast, scalable code in production
• Deep hands-on experience with LLMs (e.g., RAG, LangChain, semantic search, fine-tuning)
• You are open to the demanding nature of a start up

⚡ Why This Role?

• Extreme ownership: This is a ground-floor opportunity with massive technical scope
• Mission & intensity: You’ll help build the AI stack that powers the next wave of real-world innovation
• Onsite, high-bandwidth collaboration: The team works in-person in London, 6 days a week — visas and relocation fully supported

If you’re a technical builder who thrives on ownership, pace, and impact, it could be career-defining.
