NEW YORK (Reuters) -JPMorgan Chase ( JPM ) is hiring Guggenheim Securities executive Mike Amez, as the country's biggest bank continues to expand its technology investment banking team and to provide specific expertise to medium-sized companies, according to a staff memo.

Amez will join as Head of Mid-Cap Technology Services in September and be based in Chicago, Global Co-Heads of Technology Investment Banking Chris Grose and Greg Mendelson wrote in the memo which was seen by Reuters.

At Guggenheim, Amez was a senior managing director in the technology investment banking group, specializing in supporting IT services, cybersecurity services and hyperscale cloud infrastructure clients.

During his career, Amez "bolstered his expertise in navigating the intricate and rapidly evolving technology sector, while cultivating lasting relationships with clients," Grose and Mendelson wrote.

The hire was announced less than six weeks after the bank said it was bringing on four executives from rivals Goldman Sachs, Bank of America and Lazard to work with the technology team in the investment bank on the West Coast.

JPMorgan ( JPM ) is already a powerful player in tech banking, according to Dealogic data, and is working to deepen its sub-sector expertise, industry analysts said.

Recently it landed major deals in the tech sector, including advising Global Payments on its $24.25 billion acquisition of payment processor Worldpay.

It also advised Turn/River on its $4.4 billion take-private deal of IT management software maker SolarWinds, as well as DoorDash on its $3.9 billion acquisition of the restaurant delivery platform Deliveroo. It additionally helped CoreWeave with its $23 billion stock debut in March.
