Job Summary
Marketing Engineer
Location: London
Dept: Marketing (Growth Marketing)
Weekly office requirement: Hybrid 2 days/week
Employment type: Permanent
As our Marketing Engineer youll:
Multiply what the whole Growth Marketing team can do. You wont run a channel or own a campaign you build the systems agents and tools that let everyone else operate at a scale they couldnt 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.
What youll be doing
- Set the build roadmap. Work with VP Growth Marketing and other stakeholders to agree a quarterly roadmap of the highest-leverage builds. Youll 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 teams 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 GWIs MCP and API to generate personalised content at scale; Connect data sources and context to create a Growth Marketing OS that surfaces whats working what isnt and what we should do 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
What do I need to bring with me
- 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 dont need a computer science degree or a software engineering background but youre comfortable in low/no-code platforms happy wiring up APIs and MCP and you pick new tools up fast.
Bonus points for:
- 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 youve built wed rather see what youve shipped than read about it.
