A race engineer is a motorsport team member who analyses data to achieve the best performance from the vehicle and driver.
The race engineer's duties also include hands-on management of the vehicle mechanics, organization of the testing schedule, and assurance of compliance with regulations.
To be effective, the race engineer must have a good working relationship with not only the driver but also the rest of the team, both at and away from the track.
The race engineer's job is to evaluate the vehicle's performance gathered from both telemetry and the driver's feedback.
The race engineer then seeks to improve performance with regard to the driver's desires by adjusting suspension, engine calibrations, aerodynamics, and other variables which affect the vehicle's performance on the race track.
