Lead Manufacturing Mechanical Engineer

The future of aerospace and defense starts here.

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.

We are seeking a Lead Manufacturing Mechanical Engineer to lead mechanical design, implementation, and maintenance of custom automated fluid test systems for Ursa Major’s propulsion manufacturing facilities. You will be highly collaborative with Technicians and Operators, Manufacturing, Quality, Safety, Controls, and Design Engineers.

This role will focus on developing fluid systems that enable safe, robust, and efficient propulsion manufacturing with a focus on operator usability. You will lead fluid system design including P&ID, flow calculations, packaging, and tube routing in CAD. The scope of designs will vary from ultra-low flow bench-top to more than 1000GPM functional qualification of propulsion elements. You will be responsible for designs that use vacuum and high-pressure fluids such as nitrogen, water, kerosene, cryogenics, and more.

• Lead mechanical design with a focus on fluid systems and instrumentation layout, plus structural framing and interface panel design

• Collect requirements from test engineers and product designers

• Draft system P&ID in collaboration with I&C engineers

• Perform system analysis including flow, pressure, safety factor and expected life using hand calculations and FEA where required

• Host design review sessions with Technicians, Operators, and Engineering to generate buy-in and ensure designs meet their needs

• Provide support to build operations by designing fixtures in CAD and commissioning them on the production floor

• Be hands-on during the build process, working alongside engineers, technicians, and operators

• Have a safety-first mindset when working around and designing hardware for fluids including kerosene, water, peroxide, oxygen, nitrogen, helium, and hydrogen with pressures up to 15,000 psi, as well as cryogenics

• Generate documentation including drawings, assembly and work instructions for operation and maintenance

• 5+ years of experience with test system design or related role

• BS degree or higher in an engineering field, Mechanical, Chemical, or Mechatronic preferred (suitable experience may be substituted)

• Experience designing and troubleshooting automated hydraulic and pneumatic systems

• Expertise in CAD (SolidWorks or other) and GD&T

• Familiarity with NFPA, NEC, ASME piping codes, and other related standards

• Ability to communicate effectively, both written and verbal

• Ability to work flexibly in a fast-paced environment, collaborating with other functions and departments

• Demonstrated ability to balance requirements of multiple stakeholders and deliver projects on time

• Ability to perform physical tasks including standing for long periods, working on ladders, kneeling, crouching, working in tight spaces, lifting objects up to 25 lbs.

• Working knowledge and skilled with hand tools and able to fabricate and assemble to drawing specifications

• Expertise in Solidworks tube and cable routing

• Structural design experience for walkways & multi-point lifting

• Experience designing pneumatic proofing equipment including acoustic
