Kick-start your career with a role that's anything but ordinary. We're a small, private family office on the hunt for a bright, organised Junior Office Assistant to become the beating heart of our office — with genuine hands-on exposure to finance, operations, and our C-suite along the way.
Because we're a tight-knit team rather than a big corporate, you won't get lost in the crowd here: you'll be known, valued, and given real responsibility from day one. We're looking for someone who's smart on their feet, naturally curious, and always looking for ways to improve how things are done. You'll enjoy finding better, more efficient ways of working and be keen to contribute ideas that make a real difference.
If you're looking for a launchpad role where no two days are the same, and where your growth is genuinely invested in, this is it.
