Head of Growth - Postscript

Postscript is the AI messaging platform trusted by 20,000+ Shopify brands — including Brooklinen, Ruggable, True Classic, and Dr. Squatch.

With a mission to make SMS your number one revenue driving channel, we built the best-in-class SMS marketing platform and launched revenue-driving AI features not available on any other platform. Backed by Greylock and Y Combinator, Postscript has been fully remote since 2018.

Marketing is being rewritten. The playbooks that built B2B pipeline for the last decade are losing their edge, and the teams that win next will look more like product and engineering teams than traditional marketing departments. We're looking for the person who is already living in that future.

As Head of Growth Marketing, you'll own every way merchants discover, evaluate, and come back to Postscript: paid channels and budget, postscript.io, every traffic source, our email and SMS distribution, community, creative, and experiential. You'll run growth as an experimentation engine: fast, quantitatively rigorous, and AI-native from the ground up.

You won't just run campaigns. You'll build and ship things: free tools, interactive experiences, and AI-powered products ecommerce brands actually want to use, tested against real traffic and measured against pipeline. Part mad scientist, part operator, part builder.

This is a fully remote position that can be based anywhere in the United States.

What You'll Own

• The growth number: Own the pipeline target with sales and marketing leadership, and build the machine that hits it.
• All paid: Strategy, budget, channel mix, and creative testing across Meta, Google, LinkedIn, and whatever comes next.
• Postscript.io as a product: Conversion, testing, and new web experiences.
• Distribution: Email, SMS, community, partners, and experiential.
• Software as marketing: Conceive, build, and ship AI-powered experiences (think "Get an AI audit of your SMS program"), test them against traffic, and scale what works.
• Experiment velocity: A testing cadence measured in experiments per week, not per quarter, backed by clean measurement.
• The team: Lead and grow a team across growth, lifecycle, creative, and experiential, redesigning workflows with AI.

What We're Looking For

• 5+ years leading teams in marketing, growth, or engineering, or as a founder.
• Deep performance marketing and paid media experience at scale.
• Quantitative fluency: you conduct your own analysis and know attribution and incrementality cold.
• AI-native mindset: you use AI tools daily and have built and shipped projects with them.
• A proven track record of high-velocity experimentation that directly moved pipeline or revenue.
• A builder's bias for action: you prefer shipping a prototype on Friday over debating a strategy doc for a month.
• Creative instincts: you know great growth starts with bold ideas, not just micro-optimization.

Bonus Points

• An engineering, technical, or founder background.
• Ecommerce, DTC, or martech experience (brand or vendor side).
• GTM engineering experience (Clay, n8n, Zapier, or custom tooling).
• Hands-on experience with HubSpot and Salesforce.

Benefits & Compensation

• Salary range: USD $207,000–$287,000 base salary plus significant equity (no geo-based pay adjustments).
• Work from home: Fully remote culture with work-from-anywhere flexibility.
• Growth opportunities: Shape the future of an AI-driven SaaS platform.
• Time off: Flexible paid time off.
• Health benefits: Comprehensive health, dental, and vision insurance.
