She will oversee talent development and engagement to ensure the company attracts and retains the right people. She will be based in the Maxus London office and report directly to Federico de Nardis, the chief executive of Maxus EMEA.
De Nardis said: "We recognise that our team is our greatest asset in delivering our core values of PACE (passionate, agile, collaborative, entrepreneurial).
"Maxus EMEA needed a visionary talent leader who understood how integral these values are to our business and how to implement them right through our hiring, training and development processes."
Symons joins Maxus from ZenithOptimedia, where she held the role of head of culture and learning. She was responsible for establishing a global exchange programme, which gave over 400 employees the opportunity to live and work in another market.
She said: "Maxus has a reputation as a future-facing agency and I believe that excellent training, personal development and a strong team vision are crucial for success in today’s competitive market.
"I’m excited to work on building on this capacity in such an ambitious and progressive company."
Symons is the latest appointment to the Maxus senior EMEA team, after the promotion of Stuart Butler to EMEA head of planning (formerly UK head of strategy) and Mark Bauer to EMEA chief client officer (formerly the Barclays global client lead). These were both newly created roles.
