Lead .NET/JS Developer - Perm - Creative Agency

Tech Lead - Award Winning Creative Agency

Perm: £80,000-£90,000

Hybrid: 3 days per week to the London Office

We're working with an award‑winning digital experience studio that sits at the heart of a leading creative partnership. This team designs, builds, and evolves digital products and services used by millions - spanning high‑traffic platforms, innovative product builds, and emerging AI‑driven experiences.

This is a high‑impact, hands‑on leadership role where you'll balance architecture, delivery, and people leadership. You'll work across multiple concurrent projects, from large site builds and micro‑sites to experimental AI initiatives and commercially released products.

You'll lead multidisciplinary developers, working closely with design, UX, product, strategy, and delivery teams - and you'll be a visible technical voice with both internal stakeholders and clients.

What you'll be doing

• Owning technical discovery and defining architecture across web, product, app, and AI‑enabled platforms
• Hands‑on where needed - reviewing PRs, guiding implementation, and supporting problem‑solving
• Overseeing hosting and infrastructure within Azure
• Championing quality, performance and test automation, including end‑to‑end testing with Playwright
• Translating complex technical considerations into clear, pragmatic guidance for non‑technical stakeholders
• Supporting a fast‑moving environment where priorities shift and delivery needs to keep pace

What we're looking for

• Strong experience leading technical delivery within a digital agency or consultancy environment
• A solid backend background in C# / ASP.NET Core, with full‑stack awareness
• Experience across both frontend and backend challenges - reactive frameworks experience welcome
• Deep familiarity with Azure, including CI/CD and Azure DevOps
• Proven ability to lead teams, influence stakeholders and deliver under pressure
• Comfortable juggling multiple projects and "controlled chaos" at pace

Nice to have

• Experience integrating Azure AI Services or OpenAI APIs
• Python exposure, particularly in AI or data‑driven contexts
• Low‑code / no‑code tools (e.g. Webflow) for rapid prototyping
• Client‑facing experience presenting technical roadmaps and trade‑offs

If you want real technical influence, high‑profile work and the backing of a top‑tier creative partnership, this is it.
