Pinnuck joins the investment manager after 13 years with Goldman Sachs JBWere's quantitative research team.
He will be responsible for managing a range of active equity portfolios while using his research experience in the quantitative investment process, and will report to SSGA head of active Australian equities Anthony Golowenko.
"Rob's background in alpha generation, portfolio construction, risk modelling and attribution are complementary with SSGA's systematic quantitative investment approach," Golowenko said.
"He will be an excellent addition to our business."
SSGA also recently announced the appointment of Kelly Driscoll as head of Asia ex Japan.
Based in Hong Kong, Driscoll will report to head of Asia-Pacific Bernard Reilly.
