AWS AI Platform Engineer - Investment Management - Up to £170k + Bonus

Do you want to build the platform that every engineer and AI agent will use at this world-leading investment firm?

Most engineers inherit someone else’s decisions. This is the opposite. A world-leading investment firm has chosen to start again, building an AI-native engineering platform from a blank page, deliberately outside its core estate. With senior leadership backing and compliance built in from day one, you’ll join a small, elite team building the core of it.

The skills you write will define how every engineer, and every AI agent, builds across the firm. Your patterns won’t be used once. They’ll be used again and again, by teams you may never meet.

You’ll work agentic-first, with Claude as the preferred tool. AI will generate a lot of the code, and you’ll be the one who knows whether it’s good. You’ll review AI-assisted code with a sharp eye and write clean, idiomatic Python yourself where it matters, because every quick start and skill you create sets the standard for the firm’s pipelines, services and agents.

You’ll make the real architectural calls on API and platform design, from contract-first approaches to versioning and clean interfaces. You’ll also build automated governance and compliance into the delivery pipelines, working alongside security, identity and service-management teams.

The stack is modern and serverless on AWS: Lambda, Step Functions, API Gateway, Python, Terraform and GitHub Actions. There’s no legacy to inherit and no workarounds to untangle.

You’ll bring significant experience building cloud-native applications or developer platforms in an enterprise. That means strong hands-on AWS and Terraform, deep Python you can write cleanly without AI, and the judgement to review and correct AI-generated code. You’ll know CI/CD well, including GitHub Actions and OIDC federation, and you’ll have built automated governance or compliance controls into pipelines. You’ll also already use AI coding tools or agents regularly.

This is a principal-level role at £150,000 - £170,000 + Bonus, hybrid, with three days a week onsite.
