Company Overview:

Relativity is the first and only company to automate aerospace manufacturing by integrating intelligent robotics, software, and proprietary metal 3D printing technology. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. Our long-term goal is to upgrade humanity’s industrial base on Earth and on Mars.


At Relativity, we re-imagine the way rockets are built and flown. The Materials and Processes Engineering Team plays a crucial role in this mission by evaluating and improving the materials that make our rockets. We are searching for a Materials Engineer, Fracture Mechanics and Life Management who will serve as the Materials Engineering focal point for the understanding of fracture and fatigue behaviors of the company’s critical additively-manufactured propulsion hardware.

What you’ll do:

  • Serve as Materials Engineering subject matter expert for all engineering activities related to fracture mechanics and design for fatigue and fracture.
  • Deriving material property requirements for damage tolerant design and expected life, maximum allowable flaw size based on the loading spectra for given applications.
  • Facilitate characterization of fatigue and fracture properties of additively manufactured materials and aerospace components
  • Develop novel technologies for fracture and toughness materials characterization to be deployed in an additive manufacturing factory
  • Work across the engineering organization to support materials selection and property development
  • Facilitate technology trade studies in considering structural design for fracture tolerance and hardware life
  • Find and implement innovative approaches to improve fatigue life of hardware
  • Support failure analysis and non-conformance resolution activities
  • Mentor other engineers in fatigue and damage tolerance best practices
  • Interface with:
    • Materials engineering staff to identify, define, and fill technology gaps
    • Laboratory staff to characterize materials and processes
    • Designers to support materials selection, allowables development, and analysis
    • Manufacturing engineering to improve processes, troubleshoot issues and facilitate operations
    • Quality assurance to facilitate specification compliance validation
    • Product engineering to perform failure analysis and root cause and corrective action campaigns
    • Leadership to elevate risks and overcome roadblocks

What you need to know:

  • Bachelor’s degree in materials science or engineering, or related field
  • 5+ years of experience relevant to the competencies listed below
  • Foundational knowledge of the material behavior, characterization techniques, and associated data analysis of fatigue and fracture mechanics of metallic materials
  • A strong commitment to accountability, collaboration, and execution
  • A desire to establish and foster strong interdisciplinary relationships across the company
  • An authentic, introspective, and inclusive mindset towards technical, interpersonal, and team growth and development

Nice to haves but not required:

  • Advanced degree in material science or materials engineering, or related field, with a focus in fatigue and/or fracture mechanics of metallic material systems
  • Experience with common propulsion and L-PBF alloy systems (Ni/Cu/Ti-based)
  • Strong familiarity with aerospace fracture control requirements and standards such as NASA-STD-5009, NASA-STD-5019 and NASA-STD-5012
  • Strong familiarity with fracture testing standards such as ASTM E399, E561, E647, E1820, E2472
  • Decent familiarity with non-destructive test methods and probability of detection concepts for fracture control and life management
  • Decent familiarity with corrosion, especially as it relates to fatigue and fracture mechanics
  • Basic familiarity with NASGRO, AFGROW, BAMpF, Stress Check and other crack growth models
