Junior Developer Jobs in Mission, TX (NOW HIRING)

RRP Consulting Engineers is seeking a Senior Project Manager to lead our drainage and flood control practice in Houston.

This position has direct responsibility for stormwater and H&H projects including master drainage plans, drainage impact studies, watershed planning studies, detention basin and channel design, storm sewer and outfall systems, FEMA CLOMR/LOMR submittals, and dynamic 1D/2D modeling using HEC-RAS, HEC-HMS, and SWMM. You will own these projects end to end - scope and fee through construction - and serve as the senior technical voice and primary client contact on them.

We are a 30-year Texas practice, not a national platform. The engineer who takes this seat will sit across the table from HCFCD, City of Houston, and MUD board clients directly, with no layer between them and the decision. If you want ownership of a book of work rather than a slice of one, this is that role.
