Hearts & Science, part of Omnicom Media, are one of the fastest growing agencies in the market. Built in the digital age with agility at our core, our DNA is different from your average media agency. Our people bring to life our values of challenging conventions, celebrating difference, collaboration and positivity.

The core of our difference is rooted in our culture, something we invest significant time and energy into nurturing to ensure our people remain happy and fulfilled.

A central pillar of creating an agency Fit for the Future is making decisions that benefit our people, our agency, our partners and our clients both today and tomorrow. In media terms this means total transparency, over-and-above data governance, ethical media practices and thinking both long and short. This extends into our approach to learning & development, our diverse staff population, and social calendar.

At Omnicom Media Group, we are committed to supporting flexibility for our people while fostering collaboration, innovation, and teamwork. We have a hybrid working model (three days in the office, two working remotely), to ensure that we meet the needs of both our people and our business, balancing the benefits of in-person connections with the flexibility of remote working. Our standard working hours are 9:30 – 17:30, but we offer the ability to flex around core hours of 10:30 – 16:30 to give our people flexibility on how they manage their working day, whether that's in the office or working remotely.

We encourage open conversations between our people and managers to help navigate high-need periods and individual circumstances. Our goal is to create an environment where people feel genuinely supported to do their best - both in their careers and in their lives outside of work.

At OMG, our vision is to be an agency where difference is valued and everyone is able to thrive in a culture of equality, inclusion and belonging. We are committed to providing a truly inclusive environment that reflects today's society, where everyone is able to bring their true selves to work, and where diverse voices and backgrounds are valued, heard, and well-represented.
