Job summary

Blue Origin Engines is seeking a seasoned engineer to own fluid subsystem designs and lead stress analyses for high‑pressure piping across large thermal gradients. You will coordinate loads with civil/structural teams and work with production to resolve fabrication challenges.

The role requires mentoring junior engineers, ensuring design intent, and collaborating with supply chain to source cost‑effective parts. Travel up to 20% is expected.

Qualifications

• Minimum of a B.S. degree in engineering (Mechanical, Aerospace, or Chemical desired).
• 5+ years of professional experience within a similar sector (aerospace, petrochemical, power, etc).
• Demonstrated expertise in design and development of pressurized piping system architectures.
• Strong technical fundamentals.
• Proficiency in pipe stress analysis and associated tools (Autopipe, CAESAR, etc).
• Experience in performing fluid system sizing calculations, layout, component and material selection, and deriving concept of operations.
• Experience with hydraulic modeling tools (AFT Fathom/Arrow, HYSYS, etc.)
• In-depth knowledge of industry standards including ASME B31.3, ASME Boiler and Pressure Vessel Code (BPVC).
• Experience generating plumbing and instrumentation documents (P&IDs).
• Experience guiding and mentoring less experienced engineers
• Ability to earn trust, maintain positive and professional relationships, and contribute to our inclusive culture.

Responsibilities

• Technical ownership of fluid subsystems.
• Perform stress analysis for complex pressurized piping systems across large thermal gradients.
• Derive support loads and coordinate support schemes with civil/structural engineers.
• Work with internal and external production organizations to resolve challenges encountered during manufacturing or procurement of fluid systems.
• Work with operations team to fabricate, install, activate, and operate fluid systems.
• Ensure operations and maintenance activities are conducted consistently with design intent and defined requirements.
