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.
