Mr Gross will be based in a new Janus office located on Newport Beach, California and will be responsible for strengthening the firm’s efforts in global macro fixed-income strategies.
Janus fixed income chief investment officer Gibson Smith said Mr Gross has an “exemplary track record with decades of success”.
“He will offer an exceptional approach to navigating today’s increasingly risky markets with a focus on macro, unconstrained strategies,” said Mr Smith.
Janus chief executive Richard M Weil said Mr Gross’s involvement provides Janus with a unique opportunity to offer strategies and products that are highly complementary to those already managed by its credit-based income team.
“With Bill leading our global macro efforts and Gibson our credit-based fixed income team, I am confident Janus will be able to meet the needs of virtually any client,” said Mr Weil.
Mr Gross said he looked forward to returning his full focus to the fixed-income markets and investing, and “giving up many of the complexities that go with managing a large complicated organisation”.
“I chose Janus as my next home because of my long standing relationship with and respect for chief executive Dick Weil and my desire to get back to spending the bulk of my day managing client assets,” Mr Gross said.
