Marshall is to join in the newly created role of head of comms and community engagement in January, following a turbulent few years for Lincolnshire.
The council was threatened last year with government intervention after a number of scandals, including the exit of leader Ian Croft for misconduct. His predecessor, Jim Speechley, was jailed in 2004, also for misconduct.
The authority has since restructured, appointing a new chief executive, two assistant chief executives and a council leader.
The council's comms function is also being revamped, according to a spokeswoman. Following the redundancy of former PR manager Steve Jackson, the council plans to install three comms managers and at least four press officers, reporting to Marshall.
‘We are in a very good position to move forward both with a new senior management team and a new comms team, rebuilt from the top down,' the spokeswoman told PRWeek.
The authority will continue to use consultant Mark Fletcher-Brown as interim head of communications until Marshall's arrival.
Cambridgeshire - which employs 14,00 staff - is already recruiting for Marshall's replacement. The postholder reports to director of communications Bob Pearson.
Reporting to Lincolnshire assistant chief executive Marcus Coleman, Marshall - who has worked at Cambridgeshire for two years - will lead a team of around eight comms staff.
