About the role

Dynamic Systems (DSI), LLC is seeking a Pipe Stress, Hydraulic & CFD Engineer to support the design, analysis, and optimization of industrial process piping and HVAC/airflow systems. This role combines pipe stress analysis, hydraulic system modeling, and computational fluid dynamics (CFD) including airflow and thermal performance modeling for critical environments such as data centers, cleanrooms, and industrial facilities — to ensure safe, reliable, and efficient system operation. Analytical results inform design decisions made across mechanical, process, and controls engineering teams.

Responsibilities

• Collaborate with multidisciplinary engineering teams, including mechanical and controls engineers
• Prepare engineering calculations, technical reports, specifications, and visualizations summarizing modeling results for internal and client review
• Stay current on modeling software, industry standards, and best practices in piping, hydraulic, and airflow/thermal analysis
• Perform pipe stress analysis and flexibility evaluations using CAESAR II, AutoPIPE, ROHR2, or equivalent software
• Perform hydraulic modeling and flow analysis using PIPE-FLO
• Analyze pressure drop, flow distribution, control valve performance, pump sizing, and system operating conditions
• Evaluate piping systems for thermal expansion, sustained loads, occasional loads, vibration, wind, and seismic effects
• Evaluate equipment nozzle loads and develop support recommendations
• Build and run CFD models to evaluate airflow, temperature distribution, and thermal performance of HVAC systems and building spaces
• Analyze and validate design assumptions for critical environments (data centers, labs, cleanrooms)
• Translate CFD results into actionable design recommendations for the engineering team
• Support commissioning by comparing as-built performance to modeled predictions

Requirements

• Bachelor's or Master's degree in Mechanical Engineering, Aerospace Engineering, or a related field
• Experience in one or more of the following: pipe stress analysis, hydraulic modeling, or CFD analysis (e.g., ANSYS Fluent, Siemens STAR-CCM+, CAESAR II, AutoPIPE, ROHR2, PIPE-FLO, or similar)
• Strong understanding of fluid dynamics, heat transfer, and piping/HVAC system behavior
• Ability to communicate complex analytical findings clearly to non-specialist engineers and project managers
• Relevant experience level: approximately 2+ years (early-career) or 10+ years (senior/technical lead) — candidates at all qualified levels encouraged to apply

Preferred Qualifications

• Experience modeling mission-critical facilities (data centers, cleanrooms, pharma)
• Professional Engineer (PE) license
• Scripting/automation experience (Python, MATLAB) for modeling workflows
• Experience supporting semiconductor, life sciences, or advanced manufacturing projects

Benefits

• Competitive base salary
• 401(k) plan with company match
• Comprehensive medical, dental, and vision coverage
• Paid holidays, vacation, and personal time
• Training, professional development, and support for licensure/professional association dues
• Performance-based bonus opportunity
