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.
