About the role
We're building an early-stage go-to-market engine for a new product and looking for a GTM Growth Marketer Manager to own the experimentation loop at its core. This isn't a traditional demand gen role. You'll design and run structured outreach experiments across ICPs and message variants, interpret the signal that comes back, and feed those learnings directly into positioning - in tight partnership with our Product Marketing Manager and overlay AE team. If you think in hypotheses, not campaigns, and you're energized by turning messy early-stage signal into crisp GTM decisions, this role is for you. What You Need to Succeed GTM Experimentation 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 Demand Generation 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 Signal Interpretation & Positioning Feedback 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 Sales Enablement 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 Operations Own the outreach and measurement toolstack (sequencing tool, CRM hygiene, pipeline reporting) Define and maintain reporting that surfaces experiment learnings, not just activity metrics What You Bring to the Table 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
Requirements
- 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
- Why This Role
- You'll have direct influence on how we define our ICP and go-to-market motion - not executing someone else's playbook
- Tight feedback loop with the product and sales team
- Your work will directly shape the marketing org as it scales
