Renault has signed former Mercedes engineer Matthew Harman as deputy chief designer.
Harman worked with Mercedes as head of powertrain integration, working closely with both the power unit and chassis sides of the world championship-winning team.
Renault is looking to build its works team into championship contender by 2020 and Renault Sport Racing managing director Cyril Abiteboul believes Harman will help strengthen his team under chief technical officer Bob Bell.
"Over the past three years Bob Bell has been leading the charge for the team to reinforce its technical line-up," Abiteboul said.
