The new temporary post is being funded from £100,000 Scottish Government funding and will see a trauma informed policy developed within the council workforce and across services.
The policy will help staff recognise and deal sensitively with people who have experienced trauma.
A report to councillors said funding had been given over two years to introduce training and policy around trauma.
The council said the temporary post is funded via the Scottish Government as part of a national trauma training programme which seeks to raise knowledge, skills and understanding across different sectors of the workforce of psychological trauma.
The postholder will assist East Lothian Council in raising awareness of the impact of trauma and how best to ensure the wellbeing of both employees and service users.
Cabinet spokesperson for community wellbeing, Colin McGinn, said: “The Scottish Government is leading on an aspiration for the country and workforce to be trauma-informed.
"This is aimed at ensuring for example that our council resources are being delivered in a way that is most efficient and effective and help people to make best use of them.
"It is well documented that individuals who experience trauma have an increased risk of poorer physical and mental health.
"During the recent pandemic it is clear that many people have been working at extreme levels resulting in heightened stress and burnout. Increasing both awareness and techniques for dealing with trauma can greatly help improve the health and wellbeing of those affected and through this approach East Lothian Council can help address some of the health inequalities in our communities.”
The post is being advertised at a salary of up to £37,246.
A separate report reveals the local authority is also introducing a new mobile cleaner post to provide full time cover at eight depots across the county for
ground care amenities within its sport, countryside and leisure service.
The post which involves travelling between the sites. cleaning and removing rubbish as well as maintaining cleaning supplies is being advertised at a starting salary of £18,577 to £20,220.
