About the role

Key responsibilities & impact

Own lifecycle end to end: onboarding, activation, product-update, upgrade, and re-engagement flows for self-serve signups, API and MCP users, and event attendees.
Design and ship referral and other compounding loops that turn existing users into new users and pipeline.
Build automated, instrumented growth systems triggered by product and account signals; maintain a clean, deliverable email stack connected to the CRM.
Own paid acquisition across LinkedIn, search, retargeting, and other channels, including strategy, targeting, creative testing, budget pacing, and cost per pipeline.
Use Sumble's account intelligence to target relevant accounts and people and prove performance with holdouts and pipeline data.
Direct agency and freelance partners and decide what to outsource, bring in-house, or automate.
Own marketing GTM systems: lead routing and booking, enrichment, website visitor identification, UTMs, conversion tracking, and dashboard data.
Own attribution from first touch to closed-won and partner on Salesforce campaign architecture, lead/contact flow, and funnel definitions.
Prototype internal GTM tools using Sumble's data and API; ship valuable tools, retire ineffective ones, and document retained systems.
Own the website as a growth surface, including information architecture, conversion paths, signup/demo flows, pricing-page and landing-page experiments.
Run a standing conversion-test program and determine what to test, how to measure it, and what ships.
Ship pages and website changes without waiting in an engineering queue.
Run weekly tests across paid, lifecycle, web, and product-adjacent surfaces with hypotheses, metrics, sample sizes, and kill dates.
Maintain a shared experiment log and report weekly on the funnel to founders and Sales.

Requirements

What you’ll need

5+ years in growth marketing, growth engineering, or a technical demand role at a B2B SaaS, data, or developer-tools company, ideally one with both self-serve and sales-led motions.
Engineering-fluent; comfortable working with product, engineering and development teams and experienced with heavy experimentation.
AI-native in practice; builds with LLMs and agents (Claude, Cursor, Claude Code, MCP or similar) and can show workflows or tools shipped and still used.
Highly experimental, with demonstrated tests designed, learnings, scaling decisions, and terminated experiments.
Owned paid media with real budget and understands cost per pipeline, not just CPC.
Built lifecycle or growth loops as systems and understands CRM data models (Salesforce or HubSpot), routing, and attribution well enough to fix them.
Makes data-driven decisions and explains them clearly to founders, Sales, and non-technical teammates.
Super IC operating style; prioritizes ruthlessly and works without waiting for permission.
Experience selling to technical GTM buyers: RevOps, GTM engineers, sales or marketing ops (nice-to-have).
Hands-on experience with tools like Clay, plus product analytics and experimentation platforms (nice-to-have).
Experience growing API or usage-based products, or developer adoption of a technical product (nice-to-have).
Production front-end experience: landing pages, signup flows, CMS builds (nice-to-have).
Public body of work such as repos, posts, or experiment teardowns (nice-to-have).
Ability to complete a practical project as part of the hiring process.
