Company mission
To empower SaaS companies to build groundbreaking products that seamlessly connect with their customers’ stacks.
Role
Who you are
- 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
What the job involves
- 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
- Your job is to translate complexity into clarity—to help prospects and customers understand not just what we do, but why it matters now
- 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
Our take
The explosion of SaaS tools has created an integration nightmare for companies. More and more B2B customers are expecting their SaaS tools to integrate with each other natively. But building and managing API connections in-house as a software vendor is time-consuming and costly, diverting teams from their core roadmap and stopping sales teams from selling.
As the next-generation integration platform, StackOne is solving the challenge of building SaaS integrations at scale once and for all. Founded in 2023 by ex-Google and Oracle executives, StackOne has seen exceptionally fast growth since its launch. With its best-in-class security and real-time architecture, the company is well-positioned to become a category leader in the API integration solutions market.
