Permax Recruitment is working in partnership with a London based firm who are on the lookout for a Software Engineer. For nearly a century, our client has been building a firm as accountants, auditors, tax specialists and close advisors to clients operating in emerging markets, disrupting the status quo.
 
This has accelerated thanks to the blockchain. In 2017, a client asked to help with an ICO and they have been crypto pilled ever since, developing into what is currently the leading professional services firm on chain.
 
In 2023, they opened a new leg of the business to carve out a team dedicated to all things Web3, which is now over 80 strong and servicing near 600 digital asset clients globally. They partner with some of the industry's most influential players—cryptocurrency exchanges, blockchain innovators, Web3 pioneers, and digital asset funds—offering tailored audit, tax, and advisory services that keep pace with this fast-evolving landscape.
