We’re looking for a fractional B2B Marketing Manager to help drive day-to-day execution across content, social, and event marketing. This is a hands-on role for someone who can move quickly, execute reliably, and support ongoing marketing priorities with some oversight.

• Partner with stakeholders to support messaging and campaign rollout across priority initiatives
• Build or update landing pages / basic web content (WordPress / Framer)
• Support marketing workflows in HubSpot (lead capture, nurture, basic automation)
• Track performance and report on results; recommend improvements and next steps

Must-Haves

• Philadelphia-area (remote-first, but available for in-person meetings/events)
• B2B marketing experience
• Strong content + social execution skills
• Event marketing experience

Nice-to-Haves

• Hands-on experience with HubSpot
• Working knowledge of WordPress and/or Framer
• Google Analytics, AdWords, and paid social (Meta/LinkedIn)
• Experience improving conversion on landing pages (basic CRO / funnel optimization)
• Comfort working with growth targets and pipeline metrics
