Senior Product Marketing Manager - API & AI London, UK

London, UK

Weekly office requirement: Hybrid, 2 days per week

Employment type: Maternity cover 12 months

At GWI we’re always looking for extraordinary people who thrive on making an extraordinary impact. Right now we’re looking for a Senior Product Marketing Manager to play a key role in our Marketing team in London. If that’s you, and making a difference gets you out of bed in the morning, keep reading. It could be the start of something, well, extraordinary.

Sounds great, what will I be doing?

As our Senior Product Marketing Manager - API & AI you’ll own product marketing for GWI’s API ecosystem and our rapidly growing portfolio of AI products — including Agent Spark and our Model Context Protocol (MCP) integrations. This is a high-visibility role at the centre of GWI’s biggest growth bets. You’ll shape how our API and AI products are positioned, how they reach market, and how they drive measurable commercial outcomes — for both technical buyers and the new business personas we’re expanding into: marketers, sales teams, and product teams who increasingly need consumer insight at the point of decision.

You’ll report directly to the VP of Product Marketing and work cross-functionally with Product, Sales, Customer Success, and Partnerships. This is an executing role with genuine strategic influence — you’ll work within established frameworks while bringing your own rigour, speed, and commercial instinct to a fast-moving product area.

A few things you’ll be responsible for:

• Owning positioning and messaging for GWI’s API and AI products - building frameworks that resonate with both technical buyers and commercial decision-makers across multiple personas.
• Lead GTM strategy and launch execution for new AI product releases, from early positioning through to post-launch adoption and iteration.
• Run structured customer conversations with new personas - marketers, sales teams, product teams - to build GWI’s understanding of non-research buyers and feed insight back into positioning and product.
• Build practical sales enablement — talk tracks, objection handling, proof points — for a sales team actively transitioning to AI and technical selling motions.
• Partner closely with Product leadership to contribute to roadmap prioritisation, validate positioning early, and ensure customer insight shapes what gets built — not just how it’s launched.

It’s also fun; shaking things up is what working for GWI is all about. You’ll need to be flexible, comfortable with continuous change, and working in a high-tempo environment.

What do I need to bring with me?

You’ll need to be able to demonstrate the core skills this role requires. You don't have to tick all the boxes right away; the important thing is that you’re willing to learn. Here’s what the team will be looking for in you:

• Demonstrated experience marketing AI-powered or API-driven products to both technical and commercial buyers — you understand the space and can build credibility with each audience.
• Ability to position complex, evolving products (AI agents, integrations, API ecosystems) with clarity and confidence, even when the product is still maturing.
• Proven ability to translate technical capability into sharp, audience-specific value propositions — for developers, data leads, heads of marketing, and commercial decision-makers.
• Strong editorial judgement — you know when a message is crisp and when it’s still hand-wavy, and you can move fast between the two.
• Track record of leading end-to-end GTM for technical or AI products — from positioning through launch planning to post-launch adoption.
• Experience launching genuinely new products — not just feature updates — where the market category, buyer, and value proposition all needed to be established, not inherited.
• Comfortable operating in pre-PMF conditions: able to run structured experiments, gather signal quickly, and iterate messaging and positioning based on what you learn.
• You think in outcomes — adoption rates, usage growth, NRR, ACV impact — not just deliverables and decks.
• Experience connecting PMM work to revenue: influencing pricing and packaging decisions, contributing to expansion plays, informing what sales needs to actually close deals.
• Working knowledge of usage-based and hybrid pricing models; able to partner with monetisation specialists to pressure-test models and translate them into clear market narratives.
• Comfortable running structured customer conversations — interviews, discovery sessions, win/loss reviews — and translating what you hear into sharper positioning, better enablement, and product input.
• Experience working with new or unvalidated personas: you know how to build customer understanding from scratch, not just inherit existing research.
• You move with speed and strong judgment, quickly absorbing context, forming a clear point of view, and making confident decisions even when things aren’t fully defined.
• Comfortable working in a fast-paced, transitioning business where priorities shift and not everything is perfectly structured yet.

Equally important is attitude. We want people who think big (to make an impact), ask why (to find a better way), and show respect (to everyone, at every level, all the time). Those are our values, and they’re a big part of what we’re looking for in you.
