Role overview:

We’ve achieved breakout growth in 2024 and are now evolving our go-to-market strategy—with product marketing as a cornerstone. You’ll shape how we position, package, and bring our platform to market across key buyer personas and verticals.

This role requires balancing strategic thinking with tactical execution. You’ll operate as a player-coach, responsible for messaging, positioning, sales enablement, competitive insights, and product launches—while also rolling up your sleeves to deliver materials and campaigns yourself.

StackOne sits at the intersection of product, engineering, and GTM. Our buyers are technical (CTOs, Heads of Product), and our value prop is deep. Your job is to translate complexity into clarity—to help prospects and customers understand not just what we do, but why it matters now.

You will:

• Lead product positioning, messaging, and packaging across customer segments and verticals

• Develop GTM strategies for product launches and major releases

• Build and deliver sales enablement content—pitch decks, battlecards, product sheets

• Conduct competitive analysis and customer research to inform roadmap and messaging

• Own our voice in the market across website, collateral, and campaigns

• Collaborate closely with Product, Sales, and Customer Success to drive adoption and expansion

Requirements:

• Strong product marketing experience in B2B SaaS, ideally with platform/API or dev-focused products

• Proven success in translating technical capabilities into clear, differentiated messaging

• Experience owning end-to-end product launches and GTM plans

• Track record of building sales enablement materials that drive impact in complex sales cycles

• Skilled at working across cross-functional teams—especially Product and Sales

• Comfortable operating independently in a high-growth, remote-first environment

• Bonus: Experience with AI platforms, integrations, or API-first products

• Bonus: Hands-on experience using Clay or similar AI sales intelligence tools

Why Join Us?

• Join one of Europe’s fastest-growing startups

• Work with a veteran team of ex-employees of Google, Microsoft, Oracle, Coinbase, JP Morgan and more

• Participation in the company’s employee share options plan

• 25 days holiday + 1 additional day holiday per year of tenure

• Flexible work setup – we're hybrid-friendly

• £1,000 for your home office set up + £500/year top-up

• Cycle2Work and Electric Cars scheme

• Private health insurance (including dental & optical)

• Health, fitness and gift card discounts

• Annual team offsite to sunny spots (last ones were in Spain and Portugal ☀️)
