• Hydraulics Engineer

    Adecco US, Inc. (Waipahu, HI)


    Hydraulics Engineer – Honolulu, HI

     

    $90,000 – $140,000 (DOE) • Full-Time

     

    About the Company

     

    My client is one of Hawai‘i’s most established and trusted design and engineering firms, known for delivering high-quality work across the islands for more than 40 years. They are fully employee-owned, which means everyone—from new hires to senior leadership—shares in the company’s success. That sense of ownership shows up in the way they collaborate, support each other, and deliver projects that genuinely serve Hawai‘i’s communities.

     

    They work on a wide range of meaningful projects: public infrastructure, water and wastewater systems, schools, health care facilities, coastal and flood mitigation projects, commercial development, and long-term community planning efforts. Their culture blends technical excellence with a strong “ohana-first” mentality. People stay because the work is interesting, the team is supportive, and the company invests heavily in long-term growth.

     

    They’re expanding their water resources group and looking for a Hydraulics Engineer who wants to contribute to projects that directly improve safety and resiliency across the islands.

     

    Role Overview

     

    The Hydraulics Engineer will support flood control, drainage, and water resource projects across multiple islands.

Your work will help protect communities from flood hazards and support Hawai‘i’s long-term infrastructure planning.

    + Design and analyze hydraulic systems for flood control, drainage, stormwater, and water management projects.

    + Conduct hydrologic and hydraulic modeling using **HEC-RAS** , **HEC-HMS** , and similar tools.

    + Support permitting, environmental documentation, and technical review processes.

    Qualifications

    + Strong understanding of FEMA guidelines and Hawai‘i-specific flood ordinances.

    + Experience with hydraulic modeling (HEC-RAS, HEC-HMS).
