Head of Growth (B2B SaaS / PLG / Security Infrastructure)

A fast‑growing software company in the secure networking space is looking for a Head of Growth to build and scale its go‑to‑market engine. The company develops an open‑source, zero‑trust networking platform used by thousands of teams worldwide — from homelab users to enterprise IT and security departments. Their mission is simple: make advanced network security accessible to every modern organisation.

This is a senior, hands‑on leadership role for someone who understands how technical users adopt software and how companies buy security infrastructure.

Key responsibilities include:

• Building and leading the growth function across marketing, lifecycle, revenue operations, and partnerships
• Designing and executing a product‑led growth motion that converts open‑source and self‑serve users into paying customers
• Developing the demand engine across SEO, content, community, lifecycle, and partner channels
• Running experiments, defining growth metrics, and turning insights into scalable systems
• Working closely with Product and Engineering to optimise onboarding, activation, and monetisation
• Owning the growth tech stack (CRM, analytics, attribution, automation)
• Hiring and leading a high‑leverage growth team as the organisation scales
