Job Description
Introduction
Every customer journey starts somewhere. At Blueberry, that first impression isn't just about great design. It's about building fast, secure, and seamless digital experiences that turn visitors into active traders.
As a Senior Engineer in our Acquire squad, you'll help shape every stage of that journey. From our public website and onboarding flows to identity verification, SSO, and customer activation, you'll build the products that directly influence growth, conversion, and revenue.
This is a role for engineers who enjoy owning products end-to-end. You'll work across the full stack, collaborating with Product, UX, and Engineering to deliver software that's not only technically excellent but thoughtfully designed around the customer experience. Because when milliseconds affect conversion rates, every engineering decision matters a little more than anyone would like to admit.
Note: At Blueberry, moving with purpose means showing up, connecting, and building momentum together. This role is based onsite in Sydney, Monday to Friday, where collaboration happens best.
