• Execute build, assembly, and integration of ECLSS fluid hardware on the shop floor alongside technicians, from first article through flight hardware
• Author, redline, and maintain work instructions, assembly procedures, build travelers, and inspection plans for assigned ECLSS assemblies
• Own manufacturing process definition for assigned hardware, including tube bending and routing, fitting installation and torque, brazed and welded joint call-outs, cleaning, passivation, and assembly
• Support proof, leak, and functional testing of fluid assemblies, including test setup, instrumentation, data collection, and post-test disposition
• Identify design for manufacturing and design for assembly issues during first builds and drive them back into the design with ECLSS Design Engineering
• Disposition nonconformances and support root cause investigation and corrective action with Quality Engineering
• Define, design, and procure tooling, fixtures, and handling hardware required to execute assigned builds safely and repeatably
• Perform fit checks, interpret GD&T, and support tolerance stack-up analysis to resolve build issues
• Track build progress, part shortages, and schedule for assigned hardware, and escalate risks early
• Train technicians on new processes and drive first-pass yield, build time, and scrap improvements with data
• Support supplier manufacturing readiness for externally produced ECLSS components and assemblies

Minimum Qualifications:

• B.S. in mechanical, aerospace, manufacturing or electrical engineering, physics, mathematics, or a related technical field
• 2 + years of manufacturing experience managing a product/product line across multiple work centers and/or departments, fluid, pressurized, propulsion, or environmental control hardware in design, manufacturing, or test
• 2-4+ years of experience for Manufacturing Engineer II
• 4-6+ years of experience for Senior Manufacturing Engineer
• Hands-on fabrication, assembly, and/or integration experience; CAD proficiency (NX preferred)
• Experience with CAD tools (e.g., Siemens NX) and the ability to review designs, generate manufacturing documentation, and design assembly or test tooling

Preferred Skills & Experience:

• Hands-on experience building or testing hardware, in industry or through student teams such as Formula SAE, rocketry, CubeSat, or robotics
• Experience with aerospace, spacecraft, propulsion, or other safety-critical or high-reliability hardware
• Experience taking designs or processes from concept through build or test, and from R&D to production
• Familiarity with CAD tools, ideally Siemens NX, and PLM tools such as Teamcenter
• Exposure to thermal or structural analysis using Ansys, or similar tools
• Awareness of aerospace workmanship, design, and environmental test standards such as IPC, SMC-S-016, NASA-STD-5001, or MIL-STD-810
• Proficiency applying GD&T
• Strong problem-solving skills, including troubleshooting and structured root cause analysis
• Strong attention to detail, clear communication, and the ability to work well in cross-functional teams
• Senior Level: experience mentoring engineers or technicians and managing multiple projects at once

Additional Requirements:

• Willingness to work evenings and/or weekends to support critical mission milestones

Pay Ranges:

• Engineer/ Level I: $86,100.00 - $122,220.00
• Engineer/ Level II: $112,340.00 - $159,468.00
• Senior Engineer/ Level III: $137,760.00 - $195,552.00
