Job summary

Sumble Inc. is building the marketing function and seeks a senior, IC marketer/engineer to own growth across product, data, and campaigns. You’ll design experiments, work with product and engineering, and scale what works with a real budget and tools.

You’ll lead lifecycle, email, paid media, and GTM tooling to drive pipeline and revenue. Expect ownership, autonomy, and an impact-driven culture in a fast-moving, B2B SaaS environment.

Qualifications

• 5+ years in growth marketing, growth engineering, or a technical demand role at a B2B SaaS, data, or developer-tools company.

• AI-native in practice; build with LLMs and agents.

• You've owned paid media with real budgets and can discuss cost per pipeline.
• Built lifecycle or growth loops as systems; understand CRM data models and attribution.
• You make data-driven decisions and explain them clearly to founders.

Responsibilities

• Own lifecycle end to end: onboarding, activation, product updates, upgrades and re-engagement for self-serve and API users.
• Design and ship referral and other loops that create compounding pipeline.
• Build marketing systems rather than campaigns; signal-triggered and CRM-integrated.
• Keep email stack deliverable and wired to the CRM.
• Own paid media strategy across LinkedIn, search, retargeting, and budget pacing.
• Oversee GTM stack: lead routing, enrichment, dashboards, and Salesforce integration.
• Own website strategy, testing program and conversion optimization.
• Run weekly experiments with hypotheses, metrics, sample sizes and kill dates.
