James Schiller will join Parramatta's pre-season training later this year as the club prepares for the 2027 NRL season.
The Eels have signed the outside back on a two-year contract running through to the end of 2028.
Schiller can play on the wing or at centre, giving Parramatta another option in its backline.
Eels General Manager of Football Mark O'Neill said the club expected Schiller to strengthen its roster.
"We're really pleased to welcome James to the Parramatta Eels.
He has shown his ability to make an impact at NRL level and we believe there is plenty of growth still ahead of him.
His ability to play both wing and centre gives us added flexibility across the backline."
