## About the Role

We're open to junior and mid-level engineers, so we're particularly interested in your practical experience, technical foundations and enthusiasm for AI., * Around 2-5 years of software development experience, including hands-on experience building LLM-powered applications.

 * Strong development skills in Python and/or TypeScript, alongside solid software engineering fundamentals.
 * Practical experience working with LLM APIs, including Claude, OpenAI or Gemini.
 * Experience building and deploying RAG solutions, including embeddings, vector databases and retrieval optimisation.
 * Hands-on experience running open-source or open-weight models, such as Llama, Mistral or Qwen.
 * Practical experience using Claude Code, including its workflows, plugins, skills and other development capabilities.
 * Experience with AWS Bedrock, including model integration and associated services.
 * An understanding of responsible AI, including governance, data privacy, security and appropriate safeguards.
 * Experience working in an Agile software engineering environment.

Most importantly, you'll be curious, proactive and comfortable learning in a field that changes almost daily.

You'll enjoy collaborating with others, taking ownership of your work and explaining complex technical ideas without making everyone's head spin.
A few bonus points if you have...

We'd also be interested in experience with:

 * Agentic AI development, multi-agent systems or orchestration frameworks such as LangGraph or Strands Agents.
 * Amazon Bedrock AgentCore.
 * LLM evaluation and observability tools.
 * Building MCP servers or integrating external tools with AI agents.
 * Technologies such as Node.js, React, PostgreSQL, Docker or Terraform.
 * Developing AI features within a multi-tenant B2B SaaS environment.

## Description

* Building real AI solutions: Design, develop and deliver AI-powered features using technologies such as Claude, OpenAI, Gemini and open-weight models.
 * Making RAG work: Build and improve retrieval-augmented generation pipelines, working with embeddings, vector databases and retrieval techniques to deliver reliable results.
 * Exploring agentic AI: Help develop intelligent agents and workflows using AWS Bedrock, with opportunities to work with AgentCore and agent orchestration frameworks.
 * Working AI-first: Use Claude Code as part of your everyday engineering workflow, helping us develop smarter ways of designing, building and delivering software.
 * Making AI better: Evaluate and monitor AI performance, identifying opportunities to improve quality, reliability, speed and cost.
 * Building responsibly: Help ensure our AI solutions are secure, trustworthy and developed with appropriate governance, privacy and safeguards.
 * Collaborating and innovating: Work closely with engineers, product teams and other specialists to turn ideas into working solutions.

And because AI never stands still, neither will you. We want someone who enjoys experimenting, sharing ideas and challenging how things are done.
