Katy Griffiths and Deborah Sawyerr have been appointed deputy executive director of the Mercury Theatre in Colchester.
Both are working parents and will divide the responsibilities of the role, carrying it out as a job share.
Sawyerr was executive director of Theatre Royal Stratford East  until earlier this year, and Griffiths is former director of the Corn Exchange Newbury .
They join in September, as the theatre prepares for a major, £8.7 million capital redevelopment.
Griffiths said: “I am delighted to be taking on this role alongside Deborah at such a transformative time for the Mercury and for Colchester. As a working mother, joining an organisation that provides flexibility to parents and carers because it understands the value their experiences bring is hugely important to me. I can’t wait to get started.”
Sawyerr, who left TRSE in March to pursue recruitment consultancy, said she would continue this work alongside her role at the Mercury.
They will work with the theatre’s executive director Steve Mannix and executive producer Tracey Childs.
The Colchester theatre is a strategic partner with Parents in Performing Arts, whose co-founder Cassie Raine welcomed the decision to appoint the position as a job share.
