Working at Koru Group

Performance Foundry is a Koru Group brand. A role at Koru Group means being part of a global team of engaged, curious and humble people, doing the best for our clients together.

Because we work remotely, it’s important to be connected in our work, in our professional communities, and our personal lives. Care about your colleagues, connect in person as you travel, stay in touch even when you are far away. You’re working, but you’re a person, not a machine.

While we have standard processes, we never stop learning, changing, or improving: we are curious people. We like to learn, and we like to teach, improving ourselves and making the whole team stronger.

We all have things we like to do and areas we love to specialise in, but being part of a team means doing what needs to be done. Nothing is too good for us, or “not my job” – We actively look for ways to make our colleagues’ work easier.

During your time with Koru Group, you might touch many parts of the business, but the job description highlights your main responsibilities.


Koru Group Ltd has a virtual team with staff either traveling or working from their own homes and/or cafes and co-working spaces. We celebrate and enjoy the freedom and creativity this brings, but realise it can be hard to know how much work to do.

You will be responsible for tracking your own time and hours, but you will be expected to work around 40 hours a week from Monday to Saturday with at least 25 hours being during local business hours (Monday to Friday, 9am to 5pm).

There will be some compulsory meetings to attend each week.

As a global team, there are people working in every timezone. You do not need to respond to messages outside of your work hours, except in case of emergency or for pre-arranged meetings.

In some cases, you may be asked to work over a particular time range to achieve a project goal. We expect you to make every effort to achieve this.

We may run staff/contractor meet-ups or help finance conference or similar professional development opportunities from time to time in locations around the world. If invited, we hope you will attend if possible.
