Principal Engineer, Space & Cryogenic Pump Design

SoftInWay Inc; Boston (MA); On-site; USD 150,000 - 190,000; Full time

Job summary

SoftInWay Inc. in Boston is seeking a Principal Engineer to extend the AxSTREAM software platform for space, cryogenic, and extreme-environment applications.

You will close physics-modeling gaps and apply improved modeling to real pump and component design, including sizing, trade-offs, materials, and manufacturability. You will work at the intersection of physics modeling, software, and hands-on turbomachinery design, engaging directly with clients to shape the technical roadmap and support

Qualifications

• PhD or MS with substantial hands-on experience in CFD/turbomachinery modeling.
• Hands-on CFD and turbomachinery modeling experience with ability to validate or extend numerical models.
• Real pump or turbomachinery design experience, not modeling alone.
• Direct experience with cryogenic fluids, two-phase flow, or other extreme-condition fluid dynamics.

Responsibilities

• Identify and close physics-modeling gaps in AxSTREAM for space and extreme-environment pump applications (cavitation in microgravity, cryogenic/non-standard fluids, extreme temperatures, vacuum conditions)
• Apply improved modeling to real pump and component design — sizing, configuration trade-offs, materials, manufacturability
• Assess and build out validation data through client relationships and public/academic sources
• Work with clients and the software team to shape the technical roadmap for this work
• Support technical proposals and client engagements as this work grows
