Office Manager and CEO Assistant

Theodo is an engineering & design consultancy with offices in Paris, London, New York, Casablanca and Cape Town. We build high-quality digital products for clients across industries, and we are increasingly working with enterprise organisations on complex, high-impact tech modernisation programmes - including AI-powered code modernisation.

We run lean internally: we care about process, continuous improvement, and doing things properly. Our founders have written books on the best practice for using lean to scale agile in large organisations.

The Opportunity

Theodo UK’s office experience for employees, clients, and candidates depends on someone owning it properly.
