Human resources executive Jo Newton has joined payments technology fintech mx51 as its new people and culture head.

Newton brings almost two decades worth of experience to the role, holding positions at technology company Reejig, health insurer HCF and financial services firm Aon.

"Jo's appointment comes at a key time in the business' growth," mx51 co-founder and CTO Steven Hadley says.

"We've already doubled our global headcount in a year, we'll need to grow even faster in 2023."

"This jars against the realities of the Australian tech talent market.

"It continues to be difficult for businesses to hire, and we will be leveraging Jo's expertise to navigate this complexity," Hadley adds.

"mx51's growth to date has been incredibly impressive to watch, but can create its own challenges around hiring and retaining talent," Newton says.

"The founders have done an excellent job at managing this to date. The company is ahead of the curve in terms of flexible work arrangements and has secured some incredible people from across the technology and financial services sectors."

"My goal is to build on their efforts and enhance the company's position as an employer of choice in the financial technology sector."
