AI Engineer

AI Engineer | Up to £130,000 | Remote | Full-Time

We've partnered with a well-funded Web3 infrastructure company eliminating blockchain fragmentation to recruit an AI Engineer. Following a $20M Series A, they're scaling fast and need someone who can supercharge the org through intelligent systems, reporting directly to the CTO.

You'll own the full AI stack; internal tooling, developer experience, customer-facing products, and everything in between, in a technically ambitious environment where your work has immediate, visible impact.

Key Responsibilities:

• Build AI-powered internal tooling and automation across all teams
• Enhance developer workflows with AI coding assistants and DX improvements
• Develop and maintain customer-facing AI systems and support pipelines
• Architect large-scale RAG and knowledge systems
• Design multi-agent and agent swarm architectures
• Manage LLM integration, model selection and cost/performance optimisation
• Fine-tune domain-specific LLMs and maintain observability (LangFuse, W&B)
• Build workflow automation pipelines with n8n and LangChain

What We're Looking For:

• Proven track record shipping AI systems in production
• Strong Python, TypeScript and/or JavaScript
• Hands-on expertise with LangChain, n8n and RAG at scale
• LLM fine-tuning and multi-agent architecture experience
• Familiarity with MCP and modern AI tooling (Cursor, Claude)
• A product mindset: you identify what teams actually need and drive adoption

Bonus: Voice AI/multimodal experience or open-source AI contributions

If you want to build at the intersection of cutting-edge AI and Web3 infrastructure, with real ownership and outsized impact, this is the role for you.
