Role summary
This role is hybrid, a few days a week in the Boston downtown office.
Rocket is hiring a hands-on Growth Marketing Lead to run day-to-day execution across paid acquisition, landing pages and CRO, HubSpot workflows, content and short-form video (from scripting through briefing our freelance editor), and organic channels. You'll work directly with the Head of Growth Marketing, who sets strategy and channel priorities; you build, launch, measure and iterate, using Rocket's AI agents and tools daily to move faster and cut repetitive work. It's an individual-contributor role with no people management, built for someone who wants to grow into more ownership over the next few years.
What you'll do
Paid acquisition & experimentation
Manage paid acquisition across Google, Meta and other channels including LinkedIn, YouTube, X and emerging AI advertising platforms.
Own day-to-day campaign execution including campaign setup, budgets, optimization, targeting and reporting.
Work with the Head of Growth Marketing on CAC, pipeline and channel performance targets.
Continuously test audiences, creative, offers, messaging and landing pages.
Identify opportunities to scale spend efficiently while understanding downstream lead and pipeline quality.
CRO & website
Build and iterate landing pages for campaigns and target personas.
Develop and run A/B tests across messaging, offers, forms and page experiences.
Monitor conversion rates and identify friction across the funnel.
Work with design and development resources to ship experiments quickly.
Lifecycle, HubSpot & marketing operations
Build and maintain necessary HubSpot workflows.
Support lead routing, segmentation, campaign tracking and lifecycle automation.
Help maintain clean campaign measurement and attribution.
Brief external specialists when technical tracking or integrations require additional support.
Content & organic distribution
Help turn customer stories, product updates, research and company insights into marketing assets.
Write and edit marketing copy across landing pages, organic social and campaigns.
Script short-form video content for organic social, campaigns and landing pages, including hooks, storylines and on-screen copy.
Generate CEO and product led video content and brief freelance video editor on a regular basis to enable video distribution at scale.
Help manage Rocket's organic social presence and test ways to expand distribution.
AI & automation
Use AI daily across campaign management, research, content, reporting and experimentation.
Build and improve AI-assisted workflows that remove repetitive marketing work.
Work with Rocket's existing AI agents and infrastructure rather than manually performing tasks that can be automated.
Continuously test new AI tools and platform capabilities and identify where they can improve marketing performance.
Organic growth & new channels
Monitor organic traffic, target keyword performance and Rocket's visibility across traditional and AI search.
Support our existing SEO/AEO initiatives and help identify opportunities for improvement.
Help test new acquisition and distribution channels as Rocket's growth strategy evolves.
Support webinars, events, partnerships or other growth initiatives when they become priorities.
Who you are
3–5 years of hands-on growth, digital or performance marketing experience, ideally within a startup or B2B SaaS environment.
You've worked on a small marketing team where people wear multiple hats and are comfortable moving between channels depending on what the business needs.
You have hands-on paid media experience and can explain campaigns you've personally built, optimized and scaled.
You're comfortable inside tools whether that's an ad platform, HubSpot, a landing-page builder, analytics or an AI workflow.
You're a doer first. You enjoy building and launching things yourself rather than primarily managing other people or agencies.
You're a strong communicator and comfortable writing and editing marketing copy.
You're analytical enough to establish benchmarks, understand what moved a metric and decide what to test next.
You're AI-native and actively experiment with new AI tools and workflows.
You're curious and ambitious. You want increasing responsibility as you develop, rather than expecting to arrive with a large team or management remit.
You're comfortable working in an environment where priorities evolve quickly and where initiative matters.
Nice to have
HubSpot experience
B2B SaaS experience
Experience with CRO or landing-page experimentation
SEO/AEO exposure
Lifecycle/email marketing experience
