About NewGen

Welcome to NewGen. We're a global social creative and creator agency made up of over 100 talented people worldwide, with offices in London, Manchester, New York and Paris.

We partner with leading brands to shape culture, tell stories that matter and harness the power of social-first creative, creators and technology to drive meaningful impact.

Founded by our 30-under-30 co-founders, NewGen is an independent agency working with some of the world's biggest brands. Privately owned and built to challenge the big networks and stale traditional agencies, we move fast, live social and believe fresh ideas can compete with anyone.

Our work is trusted by brands including Pepsi, Samsung, Amazon, SEGA and Cash App, and we're the agency of choice for leading creators shaping culture today.

The Role

We're looking for a Full-Stack AI Product Engineer to join our growing AI team and take ownership of building, shipping and evolving AI-powered products.

This is not a traditional software engineering role.

We are looking for a highly autonomous builder who can take an idea from a conversation or rough brief and turn it into a working product, rapidly.

You’ll move across the entire product lifecycle:

• Understanding the problem
• Deciding how to solve it
• Building the front end and back end
• Integrating APIs and AI models
• Deploying the product
• Putting it in front of clients
• Collecting feedback
• Fixing bugs
• Shipping the next version

You’ll be expected to own what you build.

There won’t always be a detailed specification, a perfectly groomed backlog or another team waiting to take over at the next stage. You’ll work directly with our Chief AI Officer, clients and internal teams to understand what needs to exist, and then make it exist.

Claude Code Is Central to How We Build

We believe AI-assisted development fundamentally changes how quickly small, highly capable teams can ship software. Deep enablement with Claude Code is therefore a mandatory part of this role, not a nice-to-have.

We want someone who has embraced this new way of engineering: using Claude Code and modern AI development tools to dramatically accelerate prototyping, development, debugging, testing and iteration while still making strong technical decisions and taking responsibility for the software they ship.

Build. Ship. Learn. Improve. Repeat.

What You’ll Do

1. Build Products End to End

• Own products and features from initial concept through to production deployment
• Build across the full stack, including:
• User interfaces
• Application logic
• APIs
• Databases
• Authentication
• Third‑party integrations
• AI systems
• Turn loosely defined ideas and client problems into working software without waiting for exhaustive specifications
• Make pragmatic technical and product decisions that keep projects moving
• Take responsibility for the products you build after launch, including reliability, bugs, improvements and new features
• Move comfortably between greenfield products and improving existing applications

2. Build AI‑First with Claude Code

• Use Claude Code as a core part of your development workflow every day
