More spokes, thicker spokes or a hub with wider flanges would help.
What hub is it built on?
Edit: Or it could be the quick release holding the wheel....
The only option I can attempt is thicker spokes. Hub is Shutter Precision 9series, has quite a lot of spacing either side of flanges, symmetrically, accomodate electrical connectors.

As well as the closely spaced flanges, which hurt wheel axial stiffness, the long unsupported axle probably flexes quite a bit compared with a hub which has the bearings within shouting distance of the dropouts.

Will double check the qr... cheers for input
