About the role

We're looking for a Full Stack Developer whose primary expertise is building and maintaining technical solutions within Klaviyo. This is not a traditional Shopify development role.

You'll spend most of your time developing and maintaining Klaviyo email templates, HTML emails, flows, signup forms, event tracking, customer profiles, dynamic content, APIs, and marketing automations. Shopify development is required primarily to support retention marketing initiatives through Liquid, APIs, webhooks, and integrations - not as your primary specialization.

You'll partner closely with our designers, strategists, and marketers to develop clean, reliable solutions that improve customer experiences and drive measurable business results. We're looking for someone who enjoys solving complex technical problems, communicates clearly, and takes ownership from development through deployment.

What you'll do

- Develop and maintain Klaviyo email templates, flows, dynamic content, and signup forms.
- Build responsive HTML email templates that render consistently across Outlook, Gmail, Apple Mail, and other major email clients.
- Build, integrate, and troubleshoot APIs, webhooks, and third-party marketing tools.
- Debug technical issues involving Klaviyo, customer data, marketing automations, and Shopify integrations.
- Collaborate with designers and strategists to launch high-performing retention marketing campaigns.
- Develop and maintain Shopify integrations using Liquid, Shopify APIs, Shopify 2.0, and webhooks.
- Optimize website performance, page speed, and user experience when needed.
- Write clean, scalable, and maintainable code following development best practices.
- Identify opportunities to improve internal systems and technical workflows.
- Support new feature development and ongoing platform enhancements.
