ShopBacker Traits

• Agency - We take ownership and act, rather than waiting for permission. When something's blocking progress, we find a way through it and follow through until it's done.


• Judgement- We aim for high-impact decisions, not just easy wins, and we put the bigger picture ahead of individual interests. That means moving quickly and confidently, while staying thoughtful about when a call really matters.


• Learning Velocity - We pick up new skills fast and let go of old habits just as quickly when something better comes along. We benchmark ourselves against the best and keep raising our own bar.


• Tenacity - We stay in it when things get hard, keeping a level head under pressure. We debate openly before deciding, then commit fully — and support each other along the way.

• Career growth opportunities to take on greater challenges that help you realise your ambitions.


• Be part of a winning team on a journey to global scale.


• Competitive compensation based on performance.


• Candid, open, and collaborative culture where feedback is valued.
