Lead AI Engineer

Job Title: Lead AI Engineer Salary: £140,000 - £160,000 Base + 20% Bonus + Comprehensive Benefits Location: Hybrid (London) Work Type: Permanent Role: We're looking for a Lead AI Engineer to help shape the next generation of enterprise AI products within one of the fastest-growing AI businesses in the market. Built as an AI-native company inside a global enterprise software organisation, this business combines startup speed with enterprise scale. Already exceeding $10m ARR and launching multiple AI products into market, they're solving some of the most complex operational problems faced by global industrial organisations. As a Lead AI Engineer, you'll remain hands-on whilst providing technical leadership across product development. You'll influence architecture, mentor engineers, work directly with customers and help establish the engineering standards that will support the next phase of growth. This is an opportunity to help define how enterprise AI products are built—not simply contribute to them. Responsibilities: * Lead the design and delivery of production AI agents and intelligent workflows. * Architect scalable AI platforms, backend services and retrieval systems. * Drive technical direction across LLM applications, AI orchestration and cloud services. * Mentor engineers through code reviews, design discussions and technical coaching. * Partner with Product and customers to translate ambiguous business challenges into scalable AI solutions. * Define engineering standards, reusable tooling and best practices. * Build evaluation frameworks that improve AI quality, safety and performance. * Help shape the future AI product roadmap through technical leadership. Required Skills: * Extensive experience building and deploying production AI applications. * Expert Python development skills with strong backend engineering experience. * Deep understanding of LLMs, AI agents, RAG, vector databases and AI evaluation. * Experience designing cloud-native distributed systems. * Proven ability to lead technical discussions and mentor engineering teams. * Strong commercial awareness and product thinking. * Comfortable working in ambiguous, fast-paced startup environments whilst maintaining engineering excellence. Why should I apply? Few opportunities combine this level of technical ownership with the backing of an established global software business. You'll influence architecture, mentor talented engineers and help build AI products that are deployed across some of the world's largest industrial organisations. You'll join a business still in its early stages, giving you the opportunity to shape its engineering culture, product direction and technical standards whilst benefiting from significant long-term investment and an established customer base. If you're looking for a role where you can remain hands-on whilst leading from the front, this is a genuinely unique opportunity. Interested?
