Web Developer / Growth Engineer

At Hunt St, we help Australian companies directly hire top 5% remote talent in the Philippines. You will be hired directly by the client, typically as an independent contractor. We are not an outsourcing agency. All of our roles are 100% remote, so you'll be able to work from home.

Our client is an internationally operating consumer brand focused on premium electric mobility products, with a strong presence across Europe and other global markets.

They combine design, engineering, and digital innovation to deliver high-quality products and seamless customer experiences. The business is heavily focused on e-commerce growth, system integrations, and optimizing the end-to-end customer journey across digital platforms.

About the Role

We are looking for a Web Developer / Growth Engineer who can own the end-to-end website experience and system integrations across Shopify, HubSpot, and third-party platforms.

This is not a pure frontend role. You’ll sit at the intersection of conversion-focused user experience, system architecture, and growth—building robust integrations and ensuring clean, reliable data flow across systems.

You will be responsible for connecting our eCommerce platform, CRM, and external partners (including leasing/finance providers) into a seamless, trackable customer journey with reliable data flow and clear funnel visibility.

Key Responsibilities:

• Rebuild and own key conversion flows (e.g., test ride bookings currently managed via third-party tools)
• Develop and maintain the Shopify storefront, including:
  • Theme customization
  • Custom page development
  • Performance optimisation
• Design and implement API integrations, including:
  • HubSpot (forms, events, data sync)
  • Leasing / financing platforms (e.g., Lease a Bike) — including handling API integration, data exchange, and user flow across checkout
  • Other third-party systems
• Build custom lead capture, routing, and tracking systems
• Ensure accurate and consistent data flow across Shopify, HubSpot, and external platforms
• Implement event tracking and attribution (conversion tracking, funnel visibility)
• Diagnose and fix integration issues (data mismatches, failed syncs, etc.)
• Collaborate with marketing to support campaigns, landing pages, and experiments

Requirements

Required Skills and Qualifications:

• Strong Shopify development experience (Liquid, themes, custom builds)
• Strong JavaScript skills (frontend logic, API interaction, and debugging)
• Proven experience building real API integrations, including REST APIs, authentication (API keys, OAuth), and webhooks
• Must be able to clearly explain at least one production API integration you have built (systems involved, data flow, and challenges solved)
• Experience handling asynchronous data flows (e.g., webhooks, retries, failure handling)
• Experience integrating Shopify (or similar) with CRM systems (preferably HubSpot)
• Strong understanding of data flow and system architecture
• Ability to debug and resolve integration issues independently (data mismatches, failed syncs, webhook failures)
• You take ownership, communicate clearly, and deliver complete, production-ready solutions

What We’re NOT Looking For

• Developers who primarily build static websites or themes
• Candidates with only basic API exposure (e.g., Zapier-level integrations)
• Pure frontend designers without backend/integration experience

What Success looks like

• You have built production-level integrations, not just prototypes
• You understand how data flows across systems and can design it cleanly
• You take ownership of problems and deliver complete solutions end-to-end
• You think in terms of conversion, reliability, and business impact
