Location: London
Dept: Marketing (Growth Marketing)
Weekly office requirement: Hybrid, 2 days/week
Employment type: Permanent
Multiply what the whole Growth Marketing team can do. You won’t run a channel or own a campaign, you build the systems, agents and tools that let everyone else operate at a scale they couldn’t reach independently. This is one of the highest-leverage seats on the team. Reporting to the VP Growth Marketing this role is deliberately team-agnostic, sits across Growth Marketing and collaborates with the entire marketing team. You are the glue and the force-multiplier between them.
Set the build roadmap. Work with VP Growth Marketing and other stakeholders to agree a quarterly roadmap of the highest-leverage builds. You’ll have a clear backlog and the air cover to say no to the rest.
Find and automate repetitive work. Find the repetitive tasks eating the team’s time and replace them with agents and automations.
Act as a force multiplier across the team. Build systems that increase the impact of high-leverage work. Examples include: multiply our ABX operations; use GWI’s MCP and API to generate personalised content at scale; Connect data sources and context to create a Growth Marketing OS that surfaces what’s working, what isn’t, and what we should do next.Find growth levers in the funnel and fix/scale. Run analysis and discovery to discover the biggest levers and run experiments to improve conversion or unlock new growth
Experience managing campaigns, channels and funnels. You know how they work and know how to run a test. You could be a growth or performance marketer who has gone all-in on AI and wants it to be the main part of your job.
You are a problem-solver and builder by default. You welcome messy, open-ended problems and are relentlessly curious and resourceful.
You build with AI, not just chat with it: chaining prompts, wiring up agents, and automating work.
Data literacy and a systems thinker: you can think through problems end-to-end, document a clear scope and create a structured plan that links back to a measurable outcome.
You don’t need a computer science degree or a software engineering background, but you’re comfortable in low/no-code platforms, happy wiring up APIs and MCP, and you pick new tools up fast.
Built agentic workflows that drove a real marketing outcome with before/after numbers to prove it.
Hands-on with the modern martech stack: AI enabled (e.g. LLMs, MCP, vibe-coding) and core platforms (e.g. marketing automation, web CMS).
Experience running channels and campaigns at scale. You know where automation helps versus where it hurts.
Comfortable with data: pulling from APIs, shaping it, and turning it into something a team can act on.
A portfolio of things you’ve built — we’d rather see what you’ve shipped than read about it.
