FULL-STACK AI ENGINEER

Hybrid Bristol £60,000 - £80,000

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 Type Script 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 Type Script (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 Lang Chain or Llama Index
• 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.
