Kleinfelder is seeking a Senior Geotechnical Engineer / Project Manager (Transportation Focus) to join our Southern California team in either Laguna Hills or Los Angeles. This hybrid role blends remote work, in‑office collaboration, and occasional field engagement to lead and manage large transportation infrastructure and other types of projects. It is an excellent opportunity for a technical leader who thrives on managing and delivering complex projects, guiding multidisciplinary teams, mentoring junior engineers, engaging with clients, and contributing to strategic business development efforts.

Our team supports a diverse portfolio of challenging and high‑visibility projects within a design center that includes geotechnical, bridge, structural, civil, and water resources engineers, geologists, environmental professionals, and laboratory and construction oversight personnel. We work across a wide range of public and private infrastructure systems—including bridges, transit systems, roadways, water, stormwater, wastewater, and power systems, dams, tunnels and HDD installations, wet and dry above and below-ground utility infrastructure, commercial and high‑rate structures, and deep excavations—often in dense urban environments or difficult terrain.

This role requires a strong ability to plan, manage, coordinate, and execute projects with technical rigor and operational discipline as well as positioning for competitive pursuits and engaging with clients for development of business, contributing to the success of the Southern California area.

The ideal candidate will have a minimum of a Bachelor's degree in Civil, Geotechnical, or Geological Engineering. This role leads geotechnical projects from proposing and concept through closeout, combining project‑management capability with a deep, progressively responsible background in geotechnical engineering. Ideally, the candidate has a minimum of 7-8 years of experience managing multidisciplinary teams, guiding technical decision‑making, and ensuring that geotechnical considerations are fully integrated into project strategy, risk management, and client communication.

The candidate should also have a minimum of 5 years pursuing RFPs/RFQs, managing client accounts, and tracking the profitability and performance of their project/client portfolios. A Master’s degree in Geotechnical or Geological Engineering is strongly preferred. A California P.E. license is required. A California G.E. license, or the ability to obtain one within one year of hire, is highly desirable.

This position will be managing large, complex, multi-disciplinary transportation infrastructure projects, along with other types of projects. Therefore, a minimum of 5 years of transportation-related project experience and management is strongly preferred.
