Omniplex and DCSA

Omniplex is recruiting DCSA Investigators in certain markets. I am assuming Omniplex is a sub contractor to the prime contractors such as Peraton or CACI. Anyone have any insight into this matter and who Omniplex is contracted with on the DCSA contract?

I thought they were bought by constellis who is a sub to Peraton?

Constellis is the parent company to Omniplex.

I am guessing that Omniplex is a sub to Peraton for this DCSA work.
