Senior PMM: Website Strategy & AI-Driven Messaging Lead

Description The Slack website is our most visible, enduring expression of what we are and what we stand for. It's where positioning becomes real — where the narrative we build in strategy decks either holds up or falls apart. Right now, it doesn't have a single strategic owner. This role fixes that.

As Senior PMM, Website Lead, you'll own Slack's web presence end-to-end across  and  You'll set the messaging architecture, lead web strategy for Tier 1 launches, and serve as the connective tissue between PMM, SEO, Design, Engineering, Brand, and Demand Gen. This is not an execution role. You own the judgment and governance layer — and you'll use AI-enabled workflows to manage the execution layer beneath you.

What You'll Do

• Own the messaging architecture across the Slack website — defining what we say, how we say it, and ensuring every page reflects approved positioning
• Lead web strategy for Tier 1 product launches: narrative arc, page structure, and content sequencing from announcement through availability
• Make prioritization calls on which pages to refresh, which launches need a web moment, and how to sequence content across the release calendar
• Be the editorial gatekeeper — reviewing copy before it goes live, holding the line on accuracy, tone, and messaging integrity
• Partner with SEO, Design, and Engineering to translate PMM decisions into page-level execution through clear creative briefs and sharp feedback
• Drive performance in a structured cadence with the web and SEO team — connecting messaging decisions to engagement and conversion outcomes
• Build and manage AI-enabled workflows for content auditing, copy drafting, and performance monitoring — you're the manager of those agents, not the one running the tasks manually
• Lead the PMM strategy for  integration and cross-cloud web merchandising

• 7+ years of product marketing experience at a B2B SaaS company
• A track record of owning positioning and messaging in complex, multi-stakeholder environments — and protecting it
• Experience with web strategy, content architecture, or digital marketing — you understand how messaging maps to page structure, SEO, and conversion
• Strong cross-functional instincts: you move through web, design, engineering, and GTM teams without needing executive air cover to get alignment
• Genuine comfort with AI tools — you see them as an accelerant, you know when to trust the output and when to override it, and you're building workflows, not just prompting
• The ability to make fast, high-quality calls in a live environment — launches don't wait for consensus
• Sharp writing and editorial judgment — you can spot off-message copy at a glance and fix it
• The seniority to push back on vocal stakeholders and hold the line on messaging integrity
