Senior Product Marketing Manager - API & AI

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.

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:

• AI & technical product marketing - Demonstrated experience in B2B SaaS marketing, particularly for AI‑powered or API‑driven products, with the ability to engage both technical and commercial audiences and build credibility with each.
• Positioning & messaging - Proven ability to translate technical capability into sharp, audience‑specific value propositions — for developers, data leads, heads of marketing, and commercial decision‑makers.
• Commercial & pricing acumen - You think in outcomes — adoption rates, usage growth, NRR, ACV impact — not just deliverables and decks.
• Customer & market insight - Comfortable running structured customer conversations—interviews, discovery sessions, win/loss reviews—and translating what you hear into sharper positioning, better enablement, and product input.

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.

Why Join Us

This is a highly strategic product area for GWI right now, offering real opportunity to influence how we bring our AI products to market at a pivotal moment in the company’s growth. You’ll work directly with senior leadership and cross‑functional teams, with high visibility and genuine ownership of the work. A strong performance in this role could open the door to a longer‑term conversation about your future at GWI.

What’s in it for me?

• Health & wellbeing – Health cash plan, enhanced family benefits, carer days, and mental health support.
