Oleksuk had 19 goals and 21 assists in 74 games last season with Worcester of the AHL.
The Sharks also announced Friday that former forward Niklas Sundstrom has been hired as a European scout and several other changes to the front office.
Mike Ricci will work on the development of the team's forwards throughout the organization and Bryan Marchment will have a similar role for defencemen. Scout Dirk Graham will also work in the player development process with an emphasis on leadership and character development.
I feel that responsibility, I've felt it for the last two years. We core guys get a lot of minutes, we get a lot of opportunity out there. Our teammates, the organization and fans look to us to be the guys to put the puck in the net and to create momentum out there.
