About the role

Key responsibilities & impact

Scale the demand-creation engine that's already working (analyst commentary, PR, webinars, the Market Outlook) and build a website and programs that turn our community into signal.
Build the process to catch in-market demand the moment it appears, running paid, retargeting, SEO/AEO and lifecycle programmes.
Own the signal-based pipeline architecture, unifying first-, second- and third-party signals into one HubSpot record.
Fix and own the martech stack (HubSpot, Clay, ZoomInfo, Lemlist, event tooling) and cut what overlaps.
Replace vanity metrics with honest reporting: real conversion rates, real source of pipeline, numbers the business can actually plan against.
Build the marketing-to-sales handover that works: shared lead definitions, SLAs, and an account-based motion inside our existing accounts.

Requirements

What you’ll need

A track record building and running a demand engine in B2B SaaS: you've owned pipeline and revenue, not just leads and MQLs.
Hands-on experience with HubSpot, intent platforms and preferably also Clay: workflows, lead scoring, lifecycle stages, attribution and reporting. You can build automation, not just brief it.
Strong collaborator with Rev Ops, as we build one clean, signal-based pipeline.
Fluency with intent and signal-based marketing, and the discipline to make signals drive action.
Comfortable being the person who says the real number out loud, even when it's not the one on the dashboard.
The judgement to set strategy with the CMO, prioritise ruthlessly, and hire and grow a team as the function scales.
