Overview

Job Description : Mechanical Engineer – Gas Injection & Plasma Gun Systems

We are seeking a Mechanical Engineer specializing in gas injection, high-speed valve systems, and plasma-gun mechanical integration. This engineer will design, prototype, and own the hardware responsible for delivering precise gas pulses to each plasma gun and to the central target chamber.

The ideal candidate is hands-on with high-pressure gases, transient flow hardware, fast-acting valves, mechanical integration, and robust system design for harsh physical environments.

This role is central to the repeatability, symmetry, and performance of the PJMIF testbed.

Key Responsibilities

• Design mechanical gas-delivery subsystems for plasma gun feedstock (argon, hydrogen, helium, etc.).
• Design and integrate manifolds, regulators, purifiers, and filtration hardware.
• Design high-pressure storage and distribution systems.
• Model transient flow behaviour, gas pulse shapes, fill dynamics, and density profiles.
