Pantheon is a WebOps Platform that powers the open web for over 300,000 sites, serving prominent clients like Google and the United Nations. They are seeking a GTM Growth Marketer Manager to lead experimentation in their go-to-market strategy for a new product, focusing on designing outreach experiments and synthesizing market feedback to refine messaging.
Responsibilities
- Design and run outbound experiments that cleanly isolate ICP and messaging variables
- Define experiment cadence, success metrics, and review rhythm
- Maintain a living ICP scorecard tracking response rates, objection patterns, and segment-level conversion
- Build and manage outbound sequences across email, LinkedIn, and video
- Own pipeline metrics for the overlay AE team: MQLs, meeting-set rate, and conversion by segment
- Instrument campaigns so signal is attributable and actionable
- Synthesize response data, Gong call themes, and deal outcomes into positioning updates
- Partner with the PMM to translate field signal into messaging refinements
- Be the connective tissue between what the market is saying and what we're telling it
- Develop and iterate outreach sequences, talk tracks, and one-pagers tuned to each ICP under test
- Keep enablement materials in sync with positioning cycles — not on a separate track
- Work closely with overlay AEs to understand what's landing and what isn't
- Own the outreach and measurement toolstack (sequencing tool, CRM hygiene, pipeline reporting)
- Define and maintain reporting that surfaces experiment learnings, not just activity metrics
Skills
- 7+ years of B2B marketing experience, with meaningful time in demand gen, outbound, or sales-adjacent roles
- Demonstrated ability to design experiments and draw conclusions from imperfect data
- Strong instincts for outbound — sequences, hooks, personalization, and what makes a cold outreach actually work
- Comfortable working from Gong calls and deal data, not just marketing analytics
- Experience with sequencing tools (Outreach, Salesloft, Apollo, or similar) and CRM hygiene
- Collaborative working style — you'll be in a tight loop with PMM, AEs, and founders
- Experience at a company one or two stages ahead of where we are now (e.g., seed hire from Series A/B)
- Familiarity with ABM approaches and account-level signal tracking
- Background that spans both PMM and demand gen — you understand positioning, not just pipeline
Benefits
- Industry competitive compensation and equity plan
- Flexible time off, sick days, and 13 paid holidays
- Comprehensive medical insurance including Health, Dental, and Vision
- Paid parental leave (plus fertility, adoption, and other family planning benefits)
- In-office workspace
- Monthly allowance for wellness, reading, and access to LinkedIn Learning for continued development
- Events and activities both team-based and company-wide that inspire, educate, and cultivate
- Performance bonus based on company performance
