Job description

Butter & Crust is a fast-growing weekend breakfast subscription business. We deliver fresh sourdough, pastries and breakfast extras to customers’ doorsteps before 9am every weekend.

We’re looking for a hands-on Senior Ecommerce & Growth manager to own and improve the way customers discover, buy and subscribe to Butter & Crust.

This is a broad, practical ecommerce role covering our website, CRM, subscriptions, paid acquisition, CRO, analytics and the technical systems that connect everything together.

You’ll work closely with the founder, our paid creative team and external specialists, but we’re looking for someone who can personally get a lot done.

That might mean building a campaign in Klaviyo, setting up a new subscription product in Shopify and Recharge, launching an A/B test, reviewing Meta performance, editing a landing page, or using Codex or Claude Code to fix something directly.

This is not a role where you simply brief agencies and wait for things to happen.

We’re looking for a commercially minded ecommerce operator who can spot an opportunity, work out what needs to change, and help get it live.
