GTM Engineer (Growth)

Clarify

About The Position

Hi — I'm Chris. I was the first marketing hire at Clarify. Over the last year, we've built Clarify's GTM engine from scratch: standing up lifecycle systems, creating a founder brand, scaling quality content, running performance experiments, launching outbound programs, and shaping a brand that feels modern. What's become clear is that we need a dedicated partner to own the execution of growth programs—building the systems, running the experiments, and scaling what works—so we can focus on strategy and new initiatives. This isn't a traditional demand gen role. It's a systems role—one that sits at the intersection of lifecycle automation, performance marketing, signal-based outbound, and creative experimentation. When we say “Engineer,” we don’t mean software engineer. We mean someone who approaches growth like a system: designing workflows, wiring tools together, instrumenting data, shipping V1s, and iterating quickly based on signal. This role is for builders who want to own the full lifecycle of GTM execution—not manage it from a distance. It's for someone who gets energy from toggling between writing a great subject line… reviewing performance with our paid agency… designing a new lead-gen tool with our growth engineer… and partnering with sales to scale signal-based outbound. You'll use AI tools extensively to scale your output—whether that's drafting sequences, analyzing cohorts, or prototyping landing pages. We value speed and learning velocity, and the right person will be excited to leverage every tool available to ship faster and learn faster. As we scale our sales team, you'll be critical in building the marketing engine that supports their success. You'll report to me and work as a true partner—owning the day-to-day execution while we collaborate on strategy, experimentation roadmaps, and cross-functional initiatives. If that sounds like you, I'd love to meet you. — Chris

Requirements

Strong technical fluency: You can audit Customer.io flows, build Clay workflows, write SQL queries for segmentation, and debug tracking issues without heavy engineering support
You are not a software engineer—but you are comfortable working closely with data, tooling, and automation, and you enjoy getting your hands dirty in systems
3–6 years in growth, performance marketing, lifecycle, or outbound GTM at a B2B SaaS startup
You've built acquisition or lifecycle systems from scratch—not just inherited them
Exceptional writing: Clear, concise, persuasive, and human
Deep B2B SaaS metrics knowledge: CAC, LTV, activation rates, conversion funnels
Comfortable with tools like Customer.io, Clay, Zapier, Clearbit, Segment, PostHog
Experimentation mindset: You know how to design experiments, measure performance, and run fast cycles
Scrappy: You can build V1 yourself without waiting on others
We value speed and learning velocity, and the right person will use AI as leverage—not a shortcut—to ship more experiments and learn faster
