We are working with a well-established, technology-led business operating at scale, looking to hire a Full-stack AI Engineer to help build and evolve AI-powered products used in real-world commercial environments.

This is a hands-on role for an engineer who enjoys working across the stack and is excited by applying AI and agent-based systems in production, not just experimentation.

THE ROLE

You will work closely with senior technical leadership to design, build and deploy full-stack applications that integrate AI agent capabilities with robust, scalable infrastructure.

The role spans backend services, cloud infrastructure, and frontend integration, with a strong emphasis on clean architecture, specification-first development, and production-quality delivery.

KEY RESPONSIBILITIES

  • Build full-stack applications integrating AI or agent-based workflows
  • Design and develop backend services and APIs using TypeScript and PHP
  • Develop and deploy serverless applications on AWS
  • Create infrastructure as code using AWS CDK
  • Integrate LLMs and AI services into live applications
  • Containerise and deploy applications using Docker
  • Write clear technical specifications before implementation
  • Follow strong testing practices (TDD/BDD where appropriate)
  • Collaborate closely with product and technical stakeholders

ESSENTIAL EXPERIENCE

  • Strong commercial experience with TypeScript (frontend and backend)
  • Solid PHP experience with modern frameworks
  • Hands-on experience working with AI systems, agentic workflows, or LLM integrations
  • AWS experience, including Lambda and serverless architectures
  • Infrastructure as code experience (AWS CDK preferred)
  • Docker and containerisation
  • Spec-driven development mindset

NICE TO HAVE

  • Python experience
  • AI frameworks such as LangChain or LlamaIndex
  • Event-driven architectures and message queues
  • AWS Bedrock or similar AI services

WORKING ARRANGEMENT & PACKAGE

  • Hybrid working: 3 days per week in the Bristol office
  • Flexible working hours and early finish on Fridays
  • Salary range: £60,000 – £80,000
  • Comprehensive benefits package
  • Support for learning and professional development

This role would suit a pragmatic engineer who enjoys solving real problems, cares about code quality, and wants to work on AI-powered systems that actually ship.
