About the role

Flexport is hiring a Senior Growth Marketing Manager to do full funnel marketing, including acquisition, expansion, and nurture. This is a hands-on individual contributor role based in San Francisco, reporting to the Director of Growth Marketing.

You’ll manage channels directly, build the tracking and experimentation systems that show what works, and use AI-first workflows to get more done with a lean team. You’ll partner with Brand & Event Marketing, Sales, Sales & Marketing Operations, Customer Success, Product, and Engineering to win new accounts and expand existing ones.

What you’ll do

Channel owner & operator

• Manage paid media for acquisition and expansion across Google Ads, LinkedIn, Meta, and YouTube, from campaign structure and bidding to audience development.
• Forecast and allocate budget, and decide what to scale or stop based on qualified pipeline and expansion revenue.
• Own AEO and SEO: understand ranking factors, fill content gaps, increase share of relevant volume, and stay on top of changes in LLM and agentic search.
• Test new channels such as X, Reddit, and creator partnerships, and scale the winners.
• Manage our eCommerce store and direct mail, and support events and out-of-home campaigns, in service of brand, awareness, and sales.
• Build account-based programs with Sales and Customer Success: define target accounts, use buying signals, and coordinate campaigns with sales outreach and events.
• Lead agency and vendor partners with clear briefs and accountability.

Messaging, conversion, and customer marketing

• Develop value propositions, differentiation, and persona-based messaging grounded in customer research, competitive positioning, and Product narratives that convert in each channel.
• Optimize landing pages and conversion paths, including offers and personalization by segment.
• Build customer marketing programs for account expansion and attach: segment customers by usage and whitespace, and run cross-sell and upsell campaigns.

Measurement and experimentation

• Build and maintain the tracking foundation: tag management, server-side tracking, conversion APIs, and offline conversion imports that send CRM outcomes back to ad platforms.
• Connect spend to pipeline, expansion, and attach revenue using unit economics (CAC, LTV, payback period, contribution margin) and multi-touch and self-reported attribution.
• Prove incrementality with holdout and geo-lift tests, and model adstock and diminishing returns to guide channel investment.
• Run a documented, hypothesis-driven experimentation program across audiences, bids, offers, creative, and landing pages, with clear readouts.
• Use SQL and data science to segment audiences and analyze cohorts, and use reverse ETL to push modeled audiences into ad and lifecycle platforms.
• Work with Sales & Marketing Operations on campaign tracking, lead flow to sales handoff, and lead quality and account expansion analysis.

AI-first growth stack

• Build AI-first workflows for research, creative, analysis, QA, and reporting, using MCPs, computer use, and automation scripts, with expert human steering on strategy and output.
• Build and extend our growth stack and internal tools with code, APIs, command-line tools, and version control, and document each system for reuse.
• Track how AI is changing paid media and measurement, and bring what works to the team.

What you’ll bring

You bring paid media expertise, broad channel knowledge, and technical depth.

Experience

• 7+ years of B2B marketing experience reaching mid-market to enterprise buyers, with ownership of marketing-driven pipeline and account expansion.
• 5+ years of hands-on paid media experience, managing 7 to 8 figure budgets and scaling spend to the efficient frontier.
• 2+ years of building with AI, shipping workflows, automations, or internal tools.
• Logistics, supply chain, or technology marketing experience (a plus).

Technical depth

• Command of tracking, attribution, unit economics, and incrementality methods, including multi-touch models and adstock.
• Comfort with querying data warehouses, segmentation, cohort analysis, and reverse ETL, with the judgment to apply data science where it changes a decision.
• Working knowledge of A/B testing tools and experimental design.
• Operate and be a stakeholder in the sales & marketing stack: CRM, ESP, CMS, account & transaction data, web analytics, and product telemetry.

Craft and judgment

• Strong copywriting and conversion optimization skills, from first touch through expansion.
• Great taste: you use AI to craft copy and experiences, and you can tell generic output from relevant, on-brand marketing.
• AI-first instincts: you know what to automate, what to review, and where your judgment matters.
• Clear, confident communication with senior leaders and partner teams.
• An organized work style across multiple campaigns and stakeholders.

Mindset

• Curiosity about our industry and customers, and the drive to learn ocean and air freight, customs, fulfillment, and the rest of the supply chain.
• Adaptable and eager to take on new areas of marketing. Entrepreneurial spirit is a must.
