Hydrology & Hydraulics Engineer
Employer: MacKay & Somps Civil Engineers, Inc.
Location: Pleasanton, CA (Bay Area)
Pay: Competitive salary (see posting)
Type: Full-time — Civil engineering (hydrology/hydraulics; land development & public infrastructure)
What You’ll Do
-
Design storm drain systems, open-channel/closed-conduit hydraulics, and surface hydrology solutions.
-
Perform rainfall–runoff simulations and 1-D/2-D hydraulic modeling for drainage, flood studies, and stormwater management.
-
Prepare technical reports, calculations, and supporting documentation for public agencies and private clients.
-
Coordinate with internal teams, clients, and public agencies to deliver projects from design through construction.
-
Support master drainage plans, flood control design, and utility/infrastructure projects across land development and public works.
Why It Stands Out
-
Work for a long-established Northern California firm with a strong regional track record and a variety of public and private infrastructure projects.
-
Hands-on technical work (HEC, SWMM, XPStorm/Innovyze, Civil 3D) plus exposure to project coordination and increasing responsibility toward senior roles.
-
Robust benefits package and professional development supports (bonus structure, profit sharing trust/401(k), tuition assistance, flexible schedules).
Potential Trade-offs
-
Must be licensed PE in California and authorized to work in the U.S. — this limits applicants who need sponsorship or out-of-state licensure.
-
Typical Bay Area expectations for workload and responsiveness on client projects; commuting or relocation may be required.
-
Role requires solid software/tool proficiency and technical writing — steep learning curve for candidates without prior stormwater modeling experience.
Qualifications / Requirements
-
B.S. in Civil Engineering (ABET-accredited) and PE license in California required.
-
~3–7 years experience in storm drainage, surface hydrology, and hydraulics preferred.
-
Proficiency with AutoCAD Civil 3D, HEC-HMS/HEC-RAS, SWMM, XPStorm/Innovyze/WaterCAD, and Microsoft Office.
-
Strong technical writing, modeling, and communication skills; experience with land development and public infrastructure is highly desirable.
Perks / Benefits
-
Competitive compensation, generous bonus structure, profit sharing trust/401(k) plan, medical/vision/dental with HSA contributions, student loan paydown/tuition assistance, wellness reimbursement, and social/company events.
-
Flexible work schedules and a team-oriented culture with opportunities for career growth.
