She then undertook postgraduate studies in economics at Birkbeck College, London, graduating with a Master of Science (MSc) degree.^[1]

Dawes joined the Civil Service in 1989.^[2] After two years at the Department for Transport, she spent 15 years at HM Treasury, ending her time there in the role of Europe Director from 2002 to 2006.

In January 2015, Dawes was announced as the next Permanent Secretary of the Department for Communities and Local Government, succeeding Sir Bob Kerslake.^[6] She was the first permanent secretary to be appointed under a new scheme in which the Prime Minister has the final say in the recruitment process; the PM now chooses directly from a list created by the Civil Service Commissioners, rather than only having a veto over the Commissioners' preferred candidate.^[6][7] She took up the position on 1 March 2015.^[3] As of 2015, Dawes was paid a salary of between £160,000 and £164,999 by DCLG, making her one of the 328 most highly paid people in the British public sector at that time.^[8]
