About the role

Dynamic Systems (DSI), LLC is a leading engineering, fabrication, construction, and specialty systems provider serving high-tech manufacturing, semiconductor, mission critical, life sciences, industrial, and advanced technology clients throughout the United States. DSI delivers turnkey solutions including process piping, specialty gas systems, ultra high purity systems, mechanical/HVAC, process, construction, modular fabrication, utility infrastructure, and facility support services. As part of the Quanta Services family of companies, DSI combines the agility and technical expertise of a specialized engineering organization with the resources, stability, and nationwide reach of one of North America's premier infrastructure companies. DSI is currently expanding its corporate engineering capabilities and building a world-class engineering organization to support continued growth across multiple business units. This is an opportunity to join a growing team and help establish engineering standards, develop innovative technical solutions, and contribute to projects that have a direct impact on some of the world's most advanced manufacturing and technology facilities.

Position Summary: 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. We are actively seeking both early-career engineers with approximately 2+ years of relevant experience and experienced technical leaders with 10+ years of expertise. Candidates at all qualified experience levels are encouraged to apply.

Key Responsibilities:

Pipe Stress & Hydraulic Analysis
Perform pipe stress analysis and flexibility evaluations using CAESAR II, AutoPIPE, ROHR2, or equivalent software
Perform hydraulic modeling and flow analysis using PIPE-FLOAnalyze 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 recommendationsCFD & Airflow/Thermal Analysis
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
GeneralCollaborate 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 analysisPIf99529c204e6-37639-40868081

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
