When performance changes, you do not simply report the numbers. You investigate what caused the change and determine whether the issue is advertising, conversion, ranking, pricing, inventory, competition or the product itself. You are comfortable moving between strategy and execution. You can build a growth plan, review channel profitability, challenge an agency, analyse an underperforming product and go directly into Seller Central when required. You actively use AI, automation and technology to work smarter, move faster and improve performance, while applying sound commercial judgment to the outputs. You do not need a large team or extensive layers of support to get things done. You are resourceful, commercially sharp and comfortable making decisions in a fast-moving environment. Most importantly, you take ownership. You see yourself as accountable for growing the Amazon business profitably and not simply managing the activities around it. Why Join Us This is an opportunity to take meaningful ownership of an important growth channel within an established international e-commerce company. You will have the autonomy to shape how we grow Amazon, influence product and investment decisions, improve the way the channel operates and build a stronger Amazon business across multiple Truegenics brands.
