Assistant Commercial Manager

It is an exciting time to join Streamline Corporate as we continue to grow our B2B merchandise and clothing business, partnering with our clients to transform their brands across Universities, Legal, Professional and Financial Services.   With strong growth in recent years and exciting plans for the future we are looking for an experienced Assistant Commercial Manager to join us. 

We help great brands grow and transform. That's not a tagline — it's what we actually do, every day.

We work with brilliant brands, giving them the product they need to drive real turnover and the strategy to back it up. The right product, at the right price, at the right time — with service that genuinely means something. Every department plays a part in making that happen, and the commercial team sits right at the centre of it.

This is a hands-on role with real range. One day you're working through a complex quote, the next you're negotiating a deal that'll move the needle, shaping commercial range ideas, or getting into the detail of a logistics contract. You have to love the variety — and thrive in it. Every decision you make matters, and you'll be working closely with clients and colleagues across every department to make sure we maximise every move.

But here's the thing — this isn't a role for someone who works in isolation and reappears with a spreadsheet. We talk to each other. We share. We collaborate. When it's busy (and it will be), we show up for each other. When someone closes a great deal, the whole team feels it. We win together, never alone — and on the tough days, we pick each other up too.

If you're someone who gets a genuine buzz from negotiating something better, who wants to tell the room about it, who's commercially sharp but also a natural team player — this is your seat at the table. We execute relentlessly, we push each other to grow, and we're looking for someone who wants to be part of that.

Sound like you? We'd love to hear from you.
