• Among the fastest-growing tech companies in the UK

  Create connectors and integrations that make company data available to AI systems (Google Workspace, Slack, Jira, GitHub, Snowflake, Confluence and more)

• →

  Build and maintain knowledge base pipelines, MCP integrations and API connections that power AI tooling across the business

• →

  Work with security and data governance requirements to ensure integrations are safe and appropriate

• Support internal teams to create their own AI-powered data sources, automated workflows and internal tools using rapid app builder tools

• Build templates, guardrails and building blocks that make it easy for non-engineers to experiment safely

• Contribute to our internal automation platform using tools like AWS Bedrock, n8n and custom-built solutions

• Work closely with the PM and engineering lead to identify the highest-leverage opportunities

• Ship quickly, measure outcomes (time saved, errors reduced, adoption) and iterate based on what you learn

• Stay curious about emerging tools and techniques — and apply them where they'll genuinely make a difference to our engineering output

• 4+ years of software engineering experience

• Proven experience building AI tooling used by others in a commercial environment

• Strong full-stack skills in TypeScript

• Frontend skills with Next.js or React to build an interface for engineers

• Knowledge of MCP (Model Context Protocol)

• Experience shipping containerised software to Kubernetes

• Comfortable working with LLMs, embeddings and AI application patterns

• Experience designing and building API integrations

• Self-starter who takes ownership end-to-end — from understanding the problem, through design and implementation, to monitoring and iteration

• Motivated by impact — you want to see your work used and making a difference

• Experience with AWS Bedrock or other LLM provider APIs

• Experience with monitoring tools such as Datadog

• Experience with creating guardrails for products: SLOs, DORA metrics

You’ll be part of a small core team that works with engineering representatives from across the company. We have a vision of how we can accelerate the engineering process with AI and you’ll be working with this group to complete the plan. We will also experiment and adapt the plan as new AI tooling and approaches emerge.

We value shipping and learning over perfection. The goal is always to deliver something useful, learn from how it's used, and improve. You won't be directly client-facing, but your work will directly impact colleagues across the business — and you'll hear about it when something you built makes their day easier.
