Job Description

We are seeking highly driven, hands-on Systems & Fluid Design Engineers to support multiple high-urgency test-stand infrastructure and fluid system projects. This work includes designing, modifying, building, and commissioning high-pressure and cryogenic gas systems used in rocket engine development and test environments. The role is ideal for engineers who thrive in fast-paced, unpredictable environments and who enjoy both conceptual design and real-world activation of the hardware they build.

You will partner directly with lead engineers and technicians to execute end-to-end system ownership-design through commissioning-and help solve real-time challenges that arise during testing and operations.

Responsibilities

* Design new or updated high-pressure and cryogenic fluid, gas, and piping systems (e.g., LN2, LOX, high-pressure helium, nitrogen systems).

* Create system-level CAD models and drawings using NX Unigraphics (Solid Works/Creo/Catia transferable).

* Perform structural and thermal analysis using ANSYS or similar tools.

* Select and integrate commercial off-the-shelf components and specify custom fabricated tubing/piping.

* Act as the de facto project manager for system builds.

* Coordinate with technicians, welders, fabricators, and trades to efficiently execute construction.

* Oversee installation, testing, troubleshooting, and final activation of systems, solving day-of issues.

* Ensure systems are handed off fully tested, commissioned, and ready for operations.

* Work alongside lead engineers, operations personnel, and other system owners.

* Communicate clearly with both engineering and hands-on personnel.

* Navigate a fast-paced culture, prioritize multiple active projects, and act with urgency.

Essential Skills

* Bachelor's in Engineering.

* 1+ years of experience with liquid and gas pumps, high-pressure gas systems, cryogenic systems, valves, and instrumentation.

* 3+ years of design experience in an industrial setting.

* 3+ years of project management experience, including managing deadlines, costs, and coordinating with tradespeople.

* Experience with ANSYS and NX Unigraphics (or similar design software).

* Ability to provide demonstrated examples of success navigating the design, build, and activation phases.

Additional

Skills & Qualifications

* Experience in A&D, chemical refinery plants, air separation units, cryogenic systems, oil and gas industries.

* Comfortable with getting hands dirty and overcoming unexpected obstacles quickly.

* Experience in developing, commissioning, and reducing downtime.

* Ownership of the lifecycle from design to build to activation in a plant or R&D environment.
