Growth Engineer

Role Overview

As our Growth Engineer, you will own the entire technical lifecycle of our digital presence—moving our website infrastructure to a fully self-hosted environment built on Vercel and Payload CMS. Our primary focus is driving high-value enterprise demos through product experiences. We are moving away from restrictive marketing-led visual site builders (Webflow) and shifting to a highly technical, engineering-driven experimentation engine. Beyond styling static landing pages, you will be building scalable code infrastructure that enables edge personalization for our VIP customers, mapping full in-platform user context, and repairing complex analytics pipelines.

What You’ll Do

• Lead the engineering effort to migrate our marketing site and customer funnels out of Webflow and into an ultra-fast, self-hosted frontend built on Next.js/Vercel and Payload CMS.

• Architect dynamic, programmatic landing page templates for high-value VIP accounts that pull tailored assets, logos, and account metrics flawlessly without layout shifts or visual "flicker."

• Implement best-in-class, in-platform tracking that diagnoses existing data gaps and implements robust tracking so our sales teams have total visibility into what accounts are doing inside our platform.

• Seamlessly pipe event data and user traits from PostHog and outbound tooling directly down into Salesforce CRM, optimizing API payloads to maintain immaculate CRM data hygiene.

• Build and maintain our growth experimentation infrastructure.

• Design, launch, and analyze complex server-side A/B tests that target key conversion loops and drive enterprise demo bookings.

Must Have

• Strong track record of building things entirely on your own from scratch. You don't wait for a perfectly detailed specification document—you see a gap in our process or tracking and you fix it.

• Deep technical mastery of React, Next.js (App Router), TypeScript, and Node.js.

• Direct experience building with modern, open-source headless content management systems (ideally Payload CMS, Strapi, or equivalent developer-first tools).

• Advanced knowledge of event tracking architectures using tools like PostHog, Mixpanel, or Segment.

• Experience managing data flows into enterprise CRMs (Salesforce) is highly desired.

Our Operating Principles

• Extreme Ownership - Take full responsibility for our work, outcomes, and team success. No excuses, no blame-shifting — if something needs fixing, we own it and make it better.

Talent Density and Meritocracy

• Hire only people who can raise the average; 'exceptional performance is the passing grade.' Ability trumps seniority.

• We believe the best teams are built on talent density — every hire should raise the bar. We reward contribution, not titles or tenure. We give ownership to those who earn it, and we all hold each other to a high standard.

• A-players want to work with other A-players — that's how we win.

First-Principles Thinking

• Strip a problem to physics-level facts, ignore industry dogma, rebuild the solution from scratch. We don't copy-paste solutions. We go back to basics, ask why things are the way they are, and rebuild from the ground up if needed.
