Senior Product Engineer - On-Site - London - Octopus by RTG

The Role

This is a full-stack product role with real scope: you won't be handed a corner of a system, you'll own complete product slices end-to-end, from spec through to something live that customers depend on every day. Here's a taste of what that looks like in practice:

• A Chrome extension that runs compliance checks inline in Google Docs, where marketers actually write copy. Built with Monzo as the design partner. Public on the Chrome Web Store.
• A natural-language copilot for compliance work. Users ask in plain English, the platform proposes typed actions, a human approves, the action runs. Not chat over a database.
• The interface where reviewers watch the model reason through a decision, step in when they disagree, and feed structured corrections back into the rules.
• An integration surface that reaches into wherever customers create marketing: Canva, Figma, Google Docs, Contentful, Workfront, Monday.com, Frame.io for video.
• A dashboard that takes a long, unsorted list of compliance tasks and turns it into a single prioritised queue.

You think in user outcomes and shipped work, not tickets closed. Your code handles edge cases, your APIs have clean contracts, and the work you ship stays shipped. Our
