About The Position

This position is dedicated to a large-scale semiconductor manufacturing facility in Clay, New York, involving extensive deep foundation and earthwork construction. The client is seeking a Senior Field Geotechnical Engineer (Grade 26) to provide on-site engineering leadership and supervision for deep foundation and earthwork construction at the site. This role is primarily field-based; the majority of the work will involve on-site supervision of drilled shaft construction socketed into rock and earthwork with ground improvement consisting of over-excavation and replacement with engineered granular fill. As the senior geotechnical representative in the field, the successful candidate will exercise independent engineering judgment on construction issues as they arise and serve as the principal geotechnical interface with Construction, the Engineer of Record, and the client. The position is part of the Geotechnical & Hydraulic Engineering Services (G&HES) group. The successful candidate will report to and receive technical supervision and functional oversight from the G&HES Group Supervisor / Geotechnical Engineering Manager or their designee, and is expected to work independently in the field while coordinating closely with Construction, CSAOM, ES&H, and the project management team. The role is site-based at the project site for an extended duration, with potential transition to another project or permanent office thereafter, and may require travel to other company and client offices within the U.S. Excellent verbal and written communication skills and a commitment to diversity & inclusion, leadership, quality, and safety values are required.

Requirements

Demonstrated field experience supporting or supervising deep foundation (drilled shaft and/or pile) construction and earthwork/ground improvement operations.
Field experience supervising drilled shaft construction, preferably including rock-socketed shafts.
Working knowledge of earthwork and ground improvement (over-excavation and granular replacement), subgrade inspection, proof rolling, compaction control, and the associated field and laboratory testing.
Knowledge of foundation construction quality control, load testing, and field documentation (daily reports, NCRs).
Ability to read and interpret geotechnical drawings and specifications; familiarity with soil and rock characterization.
Familiarity with geotechnical software such as LPILE, APILE, SHAFT, GROUP, SLOPE/W, gINT, Settle3D, and Plaxis, as well as Microsoft Office programs.
Strong coordination and communication skills (verbal and written), with the ability to work effectively in a construction environment.
Willing and able to travel to and remain at the jobsite in New York, and other jobsites in the U.S., on short- and long-term assignments.
Professional Engineer (PE) registration in the U.S. required.

Nice To Haves

Professional Engineer (PE) registration in New York, or the ability to obtain registration by comity.
Experience on large industrial, semiconductor, pharmaceutical, energy, or infrastructure projects.
Prior involvement in drilled shaft or pile load testing programs.
Hands-on experience with ground improvement techniques (over-excavation and granular replacement, deep mixing, stone columns).
Experience adhering to established procedures in compliance with quality assurance protocols and occupational health and safety standards.

Responsibilities

Provide on-site technical supervision during drilled shaft installation socketed into rock, verifying shaft location, plumbness, diameter, and rock socket length/embedment against the approved drawings and specifications.
Verify rock socket conditions — rock type and quality, sidewall roughness, and base cleanout — and coordinate with home-office engineering on any deviations from the design basis.
Observe and document reinforcement cage fabrication and placement and concreting operations (tremie placement, concrete mix verification, slump/flow, temperature, and test cylinder preparation).
Review installation logs, concrete delivery tickets, and inspection records for quality and specification compliance.
Support and witness drilled shaft load testing programs (static, bi-directional, or dynamic), including verification of equipment calibration, observation of testing, and preliminary review of results.
Provide on-site supervision of earthwork and ground improvement consisting of over-excavation of unsuitable material and replacement with engineered granular fill.
Verify excavation limits and depths to suitable bearing strata; inspect and approve exposed subgrade (including proof rolling); and confirm granular fill gradation, placement, lift thickness, moisture conditioning, and compaction against specification.
Review field and laboratory test results (density, gradation, moisture content) and coordinate any required remediation with engineering and Construction.
Identify construction issues or deviations early and coordinate corrective actions with Construction, subcontractors, and home-office engineering.
Maintain field documentation, including daily reports, inspection records, nonconformance reports (NCRs), and quality records.
Track scope of work and schedule; coordinate closely with other technical disciplines as an integrated team.
Support the development and implementation of geotechnical investigations and the origination/review of geotechnical engineering designs, specifications, calculations, and reports as needed.
Provide technical direction to and mentor less experienced field geotechnical engineers and inspectors assigned to the site.
Lead field investigation of drilled shaft and earthwork nonconformances, including evaluation of integrity test results, and recommend corrective actions to the Engineer of Record.
