Full job description

Part of the global leader Bain & Company, Proxima is a well-established and leading management consulting firm specialising in procurement currently with offices in London, Leeds, Cardiff, Dusseldorf and Chicago.

At Proxima, we help leading brands and public sector organisations unlock value, strengthen supplier relationships, and build sustainable supply chains. We're proud of our open, collaborative, and people-focused culture, empowering our people to innovate, challenge the status quo, and grow their careers with us.

This is an exciting opportunity to join a newly established AI function at the start of its journey. As part of Proxima's wider investment in AI and digital innovation, you'll play a key role in shaping new products and capabilities that will have a real impact across the business. Based in our Cardiff office with a hybrid working model, you'll work closely with colleagues across the UK and internationally, gaining exposure to emerging technologies while helping to build and scale a growing capability. With strong momentum behind the programme and significant opportunities for development, this role offers the chance to be part of something new and make a meaningful contribution from day one.

Role Overview

AI Developers build the AI products on Proxima's Azure-based platform. The role is full stack with AI-first thinking - front-end, back-end, prompts, integrations, and everything in between.
We’re looking for an experienced developer who can slot in and deliver quickly, who brings fresh perspectives and challenges the team's defaults.
Report to the AI Solution Architect and work alongside the AI Business Analysts on live projects.

Key Responsibilities

Build

Develop AI-enabled features end-to-end - React front-ends in Azure Static Web Apps, Python back-ends in Function Apps, agent logic, prompt design, integrations.
Work with the central agent framework owned by the Solution Architect.
Write clean, well-tested code that passes code review and ships through the Azure DevOps pipeline.

AI Craft

Design effective prompts and agent workflows.
Know when to use AI and when not to - choose the right tool for the job (rules, APIs, models, retrieval).
Use AI coding assistants in your own workflow - that's the expectation, not a bonus.
Stay current with model capabilities and tooling and bring ideas back to the team.

Solution Delivery

Partner with the AI Business Analyst on requirements - ask the questions that uncover the real need.
Partner with the AI Solution Architect on technical design and trade-offs.
Own delivery of features end-to-end, including testing and support during UAT.

Quality & Standards

Hold to the team's technical standards: code review, testing, security, IaC.
Contribute to the platform - shared components, agent patterns, tooling, not just feature delivery.

Qualifications:

Strong Python and full-stack foundations, with practical exposure to AI tooling and prompting.
Demonstrable curiosity - personal projects, side-builds, or active engagement with the AI dev community.
Comfortable using AI coding assistants as part of your workflow.
Willing to question how and why - we want fresh thinking, not just hands.
Less experience required, but the bar on attitude, curiosity, and pace is high.
Comfortable with modern dev workflow - Git, code review, CI/CD, agile in Azure DevOps.
Understanding of API design and integration patterns.
Pragmatic on build-vs-buy at feature level.
