About The Position

The Associate II contributes to engineering consulting projects across the medical device, consumer product, and oil and gas industries. The role develops and validates finite element models for structural, thermal, multiphysics, fatigue, and creep analysis, and performs computational analyses for products and equipment such as surgical tools, pressure vessels, piping systems, and consumer goods. It also supports failure analysis, remediation, product development, reliability evaluation, fixed-equipment assessment, and field investigations. The position develops automated simulation workflows, solver subroutines, and surrogate models, and applies verification, validation, and uncertainty quantification to computational models. The Associate II prepares proposals, presentations, and technical reports; communicates with clients; manages projects; and works with cross-functional teams to deliver engineering solutions. Domestic travel to client worksites for meetings is 5% or less.

Requirements

• Master’s degree in Mechanical Engineering or a closely related field.
• At least five years of experience as an Advanced Simulation Engineer, Modeling and Simulation Engineer, Mechanical Engineer, Design Engineer, Computational Analyst, or in a related position requiring knowledge and practice related to hydraulic fracturing and associated field services.
• Five years of experience must include computational modeling and simulation, including nonlinear implicit/explicit FEA involving complex contacts and impact, and thermal and multiphysics analysis using tools such as Abaqus, Ansys, and/or LS-DYNA.
• Experience using Python or MATLAB for scripting and automation, and Fortran or C for subroutine development.
• Experience modeling polymers and biological tissues, including hyperelasticity, viscoelasticity, creep, and damage behavior.
• Experience with ASME BPVC, API 579, and other relevant engineering codes.
• Experience in advanced computational modeling, simulation, and analysis in medical devices, consumer products, or oil and gas.
• Experience using finite element analysis and scripting tools.
• Experience with fitness-for-service assessment of pressure equipment.

Responsibilities

• Contribute to and support engineering projects across medical device, consumer product, and oil and gas industries.
• Develop and validate finite element models for structural, thermal, multiphysics, fatigue, and creep analyses using tools such as Abaqus, Ansys, and LS-DYNA.
• Analyze components including pressure vessels, piping systems, surgical tools, and consumer products.
• Conduct failure analysis and remediation studies using test data, simulation results, and other relevant techniques.
• Automate simulation workflows and post-processing using Python and MATLAB.
• Develop finite element solver user subroutines using Fortran and C.
• Prepare proposals, presentations, and technical reports, and communicate with clients through teleconferences or in-person meetings.
• Manage projects and collaborate with cross-functional teams to deliver physics-based modeling solutions to internal and external clients.
• Characterize biological tissues and medical-grade materials using hyperelastic, viscoelastic, and damage models.
• Develop surrogate models for digital twins, uncertainty quantification, sensitivity analysis, and design-space exploration.
• Implement verification, validation, and uncertainty quantification in computational models to support compliance with ASME V&V 40.
• Analyze consumer-product performance and reliability using computational modeling and sensitivity analysis.
• Support product development through design iteration, material selection, and simulation-driven insights.
• Collaborate with design teams to improve the ergonomics, durability, and manufacturability of consumer goods.
• Design and assess fixed equipment, including pressure vessels and heat exchangers, using knowledge of ASME BPVC.
• Conduct fitness-for-service evaluations and remaining-life assessments for petrochemical and energy-sector equipment using API 579.
• Model fatigue and metal creep and implement these models in FEA software using subroutines when needed.
• Support field investigations and remediation planning for tanks, pressure vessels, and piping.
• Travel domestically to various worksites for client meetings, 5% or less.
