Location London
Weekly office requirement Hybrid, 2 days/week
Employment type Permanent
Run the engine behind our go-to-market, and build it as you go. You’ll own our marketing tech stack and the automations that connect it. Data flows cleanly between systems, leads move fast and land in the right place, and every campaign is measurable. You keep the machine running today, and you’re trusted to push it forward tomorrow: building the agents and AI-powered workflows, many of them running on Claude, that give our GTM teams an edge.
This role carries real leverage. It’s central to our FY27 goal of accelerating GTM execution through smarter operations. You’ll keep our systems trustworthy, automate the manual work, and speed leads through the funnel, which frees the wider team to chase the bigger strategic bets. You’ll report to the Marketing Operations Director and work across Marketing, Revenue, Product and RevOps, right at the heart of how GWI turns human insight into pipeline.
What do I need to bring with me?
This is a GTM engineering role at heart, so you’re a hybrid: part commercial thinker, part builder. You’ve probably come from marketing ops, sales ops or RevOps. You treat GTM like a design problem, mapping the journey and building systems that scale rather than just wiring tools together. You think about ROI, and you always ask whether a workflow actually helps someone close a deal.
You know your way around a modern martech stack, and you go deep on HubSpot in particular. You’re fluent in building workflows, managing lifecycle stages and properties, configuring lead scoring, and keeping data clean at scale. Beyond the CRM, you’ve worked across the tool types this role touches: marketing automation platforms (HubSpot, Marketo, Pardot), lead routing (LeanData), enrichment and data tooling (Clay, Clearbit, ZoomInfo), attribution (Dreamdata, Bizible), conversational and booking tools (Qualified, Drift), and workflow automation (Zapier, n8n). You won’t have used every one, but you recognize the categories and you pick new platforms up fast.
Most of all, you’re curious and resourceful. You learn new tools by getting your hands dirty. A fast-moving landscape excites you rather than fazing you, and you turn messy, open-ended problems into something structured and testable. You already build with AI, not just chat with it: chaining prompts, wiring up agents, and automating tasks that used to eat someone’s afternoon. Hands-on experience with an LLM like Claude, ChatGPT or Gemini is a real plus.
