Full Stack Developer London · Hybrid Location: London Contract type: Full time, permanent We're looking for a Full Stack Developer to be the first in house engineer building Pubity Suite, the internal product platform behind one of the World’s largest social publishers. The opportunity Pubity Suite is the operating system behind 22+ social first brands, 170M+ followers, and more than 180 billion lifetime views. It runs daily across editorial, social, commercial, finance and leadership. Dashboards, automations, AI tooling, content pipelines, talent and creator systems. The platform is real and it has users. Until now the Suite has been built by an external partner. We're bringing that build in house. You'll inherit a live platform, take direct ownership of the technical bar from day one. If you want a foundational engineering seat in a company that moves quickly, builds with AI by default, and takes the work seriously, this is the one. If you see a better way, we want to hear it. What you'll do Build the Pubity Suite • Take direct ownership of the in-house build. Ship new modules across active programmes. • Inherit code, context and live products from our external partner in a structured handover. • Own the workflow orchestration layer. N8N is our preferred orchestrator and the operating system underneath the Suite today. You'll refactor it where needed and decide when to extend in n8n versus pull logic back into code. • Set our internal engineering standards. Branching, review, deploys, environments, observability, security baseline, dependency hygiene. Build the foundations. Build AI native, by default • Treat AI as a first-class building material, not a bolted on feature. Internal agents, classification flows, copilots, intake pipelines and editorial assistants. • Work hands on with Claude and other LLM tooling. Design flows that handle failure modes well and that people return to. • Spot what should be productionised. Pubity is a Claude forward business and teams across the company build their own prompts and small workflows daily. The best of those should live in the Suite as proper product. You'll qualify, harden and ship them. Work close to the business • Sit alongside the Director of Special Projects, who owns scope and intake. Scope reaches you qualified and you're protected to build well. • Partner with our data lead/consultant on the API - BigQuery warehouse and pipeline integration. • Work with editorial, commercial, audience and operations leads on the products you ship. Who we're looking for You've shipped real products in production, end to end. You think like a builder and an operator. You care how things land with users, not just whether the code is elegant. You're comfortable owning the full stack, comfortable in a small, impactful team. You'll have • 4+ years building and shipping production web applications as a full stack engineer who owns features end to end. • Strong React and TypeScript. You can architect and refactor nontrivial frontends, not just hand roll components. • Strong Postgres or equivalent. Comfortable designing schemas, writing performant queries, managing migrations and reasoning about data integrity. • Working experience integrating LLM APIs into real products. Designing flows, handling failure modes and building useful AI features. • Experience integrating with a data warehouse or analytics backend in production. • The ability to ship without supervision. You can take a brief, sequence it, build it, deploy it and own it through to adoption. • Pragmatism. We move quickly, pay down debt deliberately and don't over engineer. • Strong written and verbal communication. You'll work with non-technical stakeholders every day. Bonus points for • Experience in media, publishing, social or the creator economy. • Familiarit
