Geotechnical Engineer

The Geotechnical Engineer runs the interface friction testing program at TRI’s Austin laboratory and develops toward signatory responsibility for that program. Interface friction work generally takes precedence; remaining capacity goes to soil-geosynthetic interaction testing (pullout and block connection) and geotechnical laboratory testing (shear strength and consolidation). Assignments flex with laboratory demand, and duties may be redirected as workload and business needs require. The work is hands-on: the engineer builds test setups, maintains equipment, and works daily with technicians, materials, and clients.

Responsibilities

Interface Friction Program

• Run, schedule, and coordinate the interface friction testing program (ASTM D5321), including laboratory assets and the testing calendar
• Receive and clarify client testing requests; write testing instructions for the laboratory
• Perform interface friction and direct sliding tests between geosynthetics and soils such as clay, silt, sand, and gravel
• Inventory samples, reconcile receipts against client instructions, and coordinate material storage and disposal
• Prepare and reduce test data for internal review; distribute final reports and coordinate invoicing
• Learn interface friction practice under senior engineers and progress toward signatory responsibility
• Prepare quotations for standalone friction programs as experience grows

Soil-Geosynthetic Interaction Testing

• Perform geosynthetic pullout testing (ASTM D6706)
• Perform block connection testing for segmental retaining wall systems (ASTM D6638)
• Support soil-structure interaction evaluations and related custom test programs

Geotechnical Laboratory Testing

• Perform direct shear (ASTM D3080), one-dimensional consolidation (ASTM D2435), and consolidated undrained triaxial (ASTM D4767) tests
• Advance into constant-rate-of-strain consolidation (ASTM D4186) as experience develops

Equipment, Technicians, and Clients

• Set up, calibrate, troubleshoot, and maintain test frames, transducers, and data acquisition systems
• Disassemble, repair, and reassemble test equipment using correct tools and torque settings
• Write basic programs for data acquisition and reduction
• Train laboratory technicians in test procedures, equipment operation, and safety
• Coordinate daily testing priorities with the Project Management Team
• Keep clients and project managers informed of schedules, status, and results
• Represent TRI on ASTM and other industry committees, with company support
• Perform other duties as assigned
