The company, which operates a host of brands including Banyan Bar & Kitchen, Manahatta, The Pit and The Box, hopes to expand further on its current portfolio of 18 bars this year.
The focus of the role will centre on the delivery of career progression and individual skills schemes and accompanies a £4.5m investment in new sites and renovations.
Arc Inspirations CEO Martin Wolstencroft said the company was delighted with the new addition to the team.
He said: “Natalie has some fantastic experience across a number of top companies and will be a major influence in helping to grow the business with passionate people and build up our teams.
“Ultimately, it’s all about giving customers the best service and ensuring everyone has the tools they need to progress in their job.
“Our strong team is the driving force behind the growth of the company and will continue to catapult the business to success.”
Newman said she was “thrilled” to be joining the company, previously having worked for McDonald's as a consultant for 15 years and then the head of training at Krispy Kreme for four years.
She revealed: “Something that really attracted me to the company is its ability to capture great talent and nurture it, which is absolutely key to success and why I believe Arc Inspirations is so well known for what it does – providing excellent customer service and a fantastic culture.
“It’s an exciting prospect looking ahead to what Arc still has to come,” she added.
