Responsibilities
* 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. Requirements




* 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).
* Strong familiarity hosting applications on Vercel and utilizing Edge Middleware, Edge Functions, or CDN‑level routing to achieve 0ms‑latency personalization.
* Advanced knowledge of event tracking architectures using tools like PostHog, Mixpanel, or Segment.
* Experience managing data flows into enterprise CRMs (Salesforce) is highly desired. #J-18808-Ljbffr
