Sauber has announced another new recruit with the addition of former Haas strategist Ruth Buscombe as strategy engineer.

Since being taken over by Longbow Finance in July, Sauber has moved to expand its team following years of financial uncertainty. Nicolas Hennel de Beaupreau was confirmed as head of aerodynamics during the Italian Grand Prix weekend, and now Buscombe - who was chief race strategist at Haas earlier this season - has also joined the Swiss team.

"The Sauber F1 Team is pleased to confirm the appointment of Ruth Buscombe as new Strategy Engineer," Sauber said in a statement. "The 26-year old Briton will start to work for the Sauber F1 Team from the Malaysian Grand Prix onwards. Buscombe has worked for the Scuderia Ferrari F1 Team, as well as recently for the Haas F1 Team."

Buscombe was part of the Haas team which impressed with strong results during its opening two races, with Romain Grosjean finishing sixth in Australia and then fifth in Bahrain.

Sauber is currently 11th in the constructors' championship having yet to score a point this season. Felipe Nasr recently pinpointed this weekend's Singapore Grand Prix as a test of the team's recent upgrades which have been introduced since the summer break.
