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.

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.

• 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.

• 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.

• 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 – Big Query warehouse and pipeline integration.
• Work with editorial, commercial, audience and operations leads on the products you ship.

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.

• 4+ years building and shipping production web applications as a full stack engineer who owns features end to end.
• Strong React and Type Script. 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.

• Experience in media, publishing, social or the creator economy.
• Familiarity with Supabase specifically, or with similar BaaS platforms.
• Big Query experience.
• Familiarity with n8n. Equivalent experience with code‑first orchestrators such as Temporal, Airflow or Prefect is welcome.
• Design sensibility. You care how things look and feel, not just how they function.
• Experience replacing legacy or external vendor systems with in‑house builds.
• Open source contributions or side projects we can look…
