Job Description

Water is the life source of every community, and our mission is to help preserve it by creating and maintaining safe, efficient, and sustainable water facilities and processes.

Parsons helped transform the industry through some of the most complex water and wastewater projects in the world. We’ve designed and built advanced wastewater and recycled water treatment facilities, applying innovative solutions to reliably and cost‑effectively deliver billions of gallons of clean water to communities around the world. As a seller‑doer in our California design team, you will build on this legacy.

Parsons’ wastewater practice is growing here in California, and as a result we are looking for a Principal Project Manager to join our Southern California team. Have you developed strong relationships and a stellar reputation with local Clients? Have you lead the design efforts of new and existing water and wastewater infrastructure? Do you have the technical, management, and leadership skills to successfully deliver exciting and challenging design projects?

The Principal Project Manager must be a licensed P.E. in California and have experience delivering design elements on projects that range from $25 million to $150 million in constructed value.

In this role, you will drive growth by independently identifying and securing new programs and by partnering with our business development professionals on major pursuits. As such, experience identifying and developing opportunities, writing technical proposals, presenting to clients and managing outside stakeholders will be instrumental to your success. The position will be located at Parsons Pasadena, California office with a hybrid work‑from‑home schedule up to two days a week.
