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 users are compliance and marketing teams at leading fintechs. They use Adclear every day, and they'll tell you fast when something's wrong, which is exactly the kind of feedback loop that makes this job good. What you'll do Own product delivery. Take features from spec to production, frontend-first but covering backend and integration where needed. Build the product surfaces compliance reviewers live in: workflows, review UIs, the moments where model output meets human judgement. Work with AI in the critical path. Ship features where the model is genuinely part of the product, not a bolted-on feature. Ship a change to production on your first day and a feature in your first week. We deploy continuously, so you'll feel the pace immediately. Have real input on what we build, how we build it, and which problems are worth solving next. Nobody here is precious about a roadmap someone else wrote. Requirements What we're looking for Independent delivery. You can own and ship end-to-end product slices with minimal supervision. Your track record shows features that shipped, stuck, and solved real user problems. Product trade-off judgement. You balance speed, quality and user impact under ambiguity. You push back when something is underspecified, and make pragmatic calls when it needs to ship anyway. Product taste. You notice when something feels wrong and aren't afraid to raise it. You care about the smaller details while still knowing when to ship at pace. Cross-functional pragmatism. You work effectively with founders, designers and AI engineers, and you unblock yourself rather than waiting on someone else. AI literacy. You're fluent with modern coding tools (Claude Code, Cursor, agents). You treat them as collaborators, know…
