Sr. Principal Technical Product Marketing Manager – Foundation Pillar

Team: Product Marketing
Reports to: VP, Product Marketing

About the Role

6sense is the GTM Intelligence Platform, and Foundation is the layer the rest of it stands on — "platform, data, infrastructure: the backbone everything builds on." It owns account and people data, matching and identity, the APIs and MCP framework, security and connectors, signal publication, and the workflows that move data through the system. When buyers ask whether 6sense is accurate, extensible, secure, and composable, the answer lives here.

We're looking for a Principal Technical Product Marketing Manager to own positioning, messaging, and go-to-market for the Foundation pillar. This is the most technical seat on the PMM team. You'll translate deep capabilities — identity resolution, data coverage and accuracy, API extensibility, the MCP framework, security and compliance — into differentiated stories that win over the technical and economic buyers who scrutinize them: RevOps architects, IT and security teams, data leaders, and increasingly developers building agentic GTM stacks.

You'll also carry one of the most strategically important narratives in the company: that 6sense is a composable intelligence layer other systems and AI agents plug into — "AI to the data, not data to the AI" — rather than a closed destination. With the MCP framework moving to GA, this is a present-tense story, and you'll be the one who tells it credibly.

What You'll Own

• Positioning and messaging for the Foundation pillar — platform, data, infrastructure, identity and matching, APIs and the MCP framework, security and connectors, signal publication, and workflows. You set the narrative and keep it coherent with the Intelligence and Activation pillars.
• Technical proof. Turn capability into credibility: architecture explainers, technical briefs and whitepapers, benchmarks, and reference narratives that substantiate the "backbone everything builds on" claim — especially around data accuracy, coverage, and identity resolution.
• The composable / MCP-agent story. Own the infrastructure-layer narrative — 6sense as the data and intelligence layer that agentic GTM stacks compose with. Lead GTM for the MCP framework and the developer / technical-buyer audience it opens up.
• Differentiation for the data and identity layer. Make the case against point data providers and infrastructure alternatives — coverage, match rates, identity quality, enrichment, security posture — and arm the field to win on it.
• Field and partner enablement for technical evaluations. Build the battlecards, objection handling, FAQs, and solution content that win RFPs, security reviews, and technical POCs. Partner with Sales Engineering to make the technical buyer's diligence a place 6sense wins.
• Launches. Drive end-to-end GTM for Foundation releases: new data assets, API and MCP capabilities, security packages (SCIM, SSO role mapping, audit, custom roles), connectors, and workflow features.
• Cross-functional partnership. Work shoulder-to-shoulder with the Foundation Product and Engineering leaders to shape roadmap-to-market, and with Customer Success to surface the post-sale and admin/security use cases that prove the platform's breadth.
• Market and competitive intelligence for the data and platform layer, feeding insight back into roadmap and pricing/packaging conversations.

What You'll Bring

• 8+ years in product marketing, technical product management, or a closely related function, with substantial technical PMM experience for platform, data, infrastructure, API, or developer products.
• A proven ability to translate technical concepts — APIs, data pipelines, identity resolution, integrations, security, and AI/agent architectures like MCP — into crisp positioning and business value, without losing the engineers in the room or the buyers outside it.
• A track record owning messaging for technical products and enabling technical sales motions (Sales Engineering, RFPs, security reviews, POCs).
• Hands-on, not hand-wavy. You'll personally call the APIs, stand up and configure the MCP server, connect it to an agent, and build the demo — and your messaging is sharper because you've done the thing, not just read the spec.
• Strong writing — you can produce content that is technically rigorous and genuinely clear, from a one-line value prop to an architecture whitepaper.
• Fluency with the B2B SaaS buyer, ideally in martech, RevTech, or data platforms, and comfort selling to technical and economic buyers (RevOps architects, IT, security, data teams, developers).
• The judgment and presence to operate as a senior individual contributor: set strategy, lead cross-functionally without authority, and influence product and executive stakeholders.

Nice to Have

• Hands-on familiarity with data enrichment and identity (waterfall enrichment, matching, intent data), MCP and agentic AI architectures, or composable/API-first platforms.
• Experience marketing to developers or technical evaluators, including documentation-adjacent and developer-community work.
• Background in or adjacent to GTM intelligence, ABM, sales intelligence, CDP, iPaaS, or identity platforms.

What Success Looks Like

In your first 6–12 months, Foundation has a differentiated, defensible position that technical buyers recognize; the composable/MCP infrastructure story is landed with the field and the market as something that exists today, not a roadmap promise; the data and identity credibility story is substantiated with proof, not assertion; and the field has the enablement to win the technical evaluation every time it comes.
