## About the role

Apex is seeking a Senior Propulsion Engineer with deep experience in pressurized fluid systems to own the feed-system design of the propulsion modules that fly on Apex spacecraft. You will be the fluidics authority on the propulsion module team — designing the wet side of the module from the tank through the routing to the thruster and cathode, defining and running the test campaigns that qualify it, and carrying the hardware through range safety and into space. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Bachelor's degree in mechanical, aerospace, chemical, or a related engineering field
- 6+ years (Sr) / 8+ years (Staff) of experience in fluid systems engineering, with substantial hands-on work on pressurized fluid or propellant feed systems
- Deep knowledge of pressurized fluid system design — component selection, routing, joints, and design to MEOP/proof/burst factors of safety
- Strong fluids analysis skills — flow and pressure-drop, transients/water-hammer, filtration, and thermal-fluid behavior
- Hands-on experience defining and executing fluid-system test campaigns, including leak, proof, burst, and functional testing
- Direct experience with range safety and pressure-systems requirements (e.g., SSCMAN/AFSPCMAN 91-710), including fracture control and hazardous operations
