Role Overview

I am supporting a high growth D2C supplement brand who are seeking a high-leverage Senior Growth Engineer to operate at the critical intersection of ecommerce and AI automation. This is a pivotal role designed for a technical 'builder' who can bridge the gap between commercial strategy and execution. Working directly with the ecommerce leadership, you will own the technical roadmap for growth, focusing on building, automating, and optimising the systems that drive our commercial performance and operational efficiency.

Key Responsibilities

  • Ecommerce Optimisation: Develop and enhance our Shopify experience through custom Liquid development, CRO experiments, and advanced UX testing to drive conversion.
  • Technical Ecosystem Management: Lead the integration and optimisation of our tech stack, including Klaviyo, Recharge, and custom APIs, ensuring a seamless data flow across the customer journey.
  • AI & Automation: Architect and deploy Python-based scripts and AI workflows to automate manual processes, accelerate output, and improve business-wide efficiency.
  • Retention & Lifecycle: Build sophisticated retention automations and lifecycle flows that measurably increase Customer Lifetime Value (LTV).
  • Data Infrastructure: Enhance tracking, data visibility, and performance infrastructure to ensure all growth experiments are accurately measured and scalable.

Required Skills & Experience

  • 3–6 years of experience in a high-growth startup, D2C brand, or specialised ecommerce agency.
  • Expert-level proficiency in JavaScript, HTML, CSS, and Shopify/Liquid development.
  • Proven ability to write Python or similar scripting languages for automation and AI-driven workflows.
  • A 'builder' mindset with a bias for action you prefer shipping code to sitting in strategy meetings.
  • Strong commercial acumen with an understanding of unit economics and growth metrics.

Nice-to-Have Qualifications

  • Experience with headless e-commerce architectures.
  • Deep understanding of attribution modelling and advanced GA4 configurations.
  • Prior experience in a remote-first, fast-paced environment.
