You do not want a posterior pelvic tilt under load. The important thing is to keep your spine pretty straight up and down during the dip and maintain the lumbar lordosis (which would be lost if the pelvis tilted posteriorly).

The glutes will contract naturally as part of the concentric movement of the jerk (jumping/driving the bar upwards).
