What is the difference between Primary Fluid Systems vs Hydraulic Technicians?

AspectPrimary Fluid SystemsHydraulic Technicians
CertificationsRelevant certifications in fluid systems, HVAC, or mechanical maintenanceHydraulic-specific certifications often preferred
Work EnvironmentIndustrial, manufacturing, or maintenance settings involving fluid systemsIndustrial machinery, construction, or maintenance involving hydraulics
Job FocusDesign, installation, and maintenance of fluid systemsRepair, troubleshooting, and servicing hydraulic equipment
Industry UsageCommon in manufacturing, energy, and industrial sectorsCommon in construction, manufacturing, and heavy equipment sectors

Primary Fluid Systems professionals focus on designing, installing, and maintaining fluid systems across various industries. Hydraulic Technicians primarily troubleshoot and repair hydraulic machinery. While both roles require knowledge of fluid mechanics, their responsibilities and certifications differ slightly, with Primary Fluid Systems roles emphasizing system setup and Hydraulic Technicians specializing in repair and maintenance.

Job description

About the Team: 

The Materials & NDE Engineering team is responsible for the development, characterization, and inspection of materials across the Terran R launch vehicle. We specialize in rapid implementation of material systems through robust internal testing capabilities and first principles driven qualification approaches. We have recently made our first primary structure barrel, supported introduction of next generation powder additive alloys in the Aeon-R engine, and developed 100% in-cell NDE inspection capabilities for WAAM manufactured hardware.

About the Role:

  • Lead the Stage Materials and Processes Engineering team as the accountable M&P leader for development, design, manufacturing, and reuse of Relativity's primary structures, mechanisms, and fluid systems products
  • Define team expectations, roles & responsibilities, goals, priorities, and communication channels
  • Collaborate with key stage partner teams and leaders across the product lifecycle: designers, analysts, METLab, weld, NDE, manufacturing, quality, and supply chain
  • Drive technical direction and strategy for Stage M&P, continuously providing feedback to the team and key partners
  • Fight to keep Terran-R on track through manufacturing dispositions, appropriate risk mitigation, and root cause/corrective action
  • Set the bar for both leadership and technical excellence across the team
  • Support annual operating plan and organizational activities (budget, headcount, staffing)
  • Foster an empathetic, supportive, accountable, honest, and communicative team culture

About You:

  • Bachelor's degree in materials science or engineering, or related field
  • 4+ years of relevant materials & process engineering experience
  • Experience with general materials and processes activities such as M&P qualification, failure analysis, experimental design, and allowables development
  • Demonstrated ability to lead with technical excellence, empathy and inclusivity across a diverse team
  • Accountable, collaborative, and biased towards action

Nice to haves but not required:  

  • Experience across the entire launch vehicle programmatic lifecycle
  • Experience with all stage products (primary structures, mechanisms, and fluid systems)
  • Experience across all stage materials and processes (aluminum, nickel-based, stainless steel, FSW, arc fusion welding, structural composites, etc)
  • Experience with all stage M&P engineering disciplines (fatigue and damage tolerance, corrosion, tribology, oxygen compatibility, etc)
