Job details

Senior Additive Simulation Engineer

Relativity Space is building rockets and the advanced manufacturing systems to produce them. We are seeking a Senior Additive Simulation Engineer to develop and validate multi-physics simulation workflows for metal additive manufacturing that enable reliable, repeatable production of flight hardware for the Terran R program.

Skills

  • Proven experience building and validating FEA/process simulations for metal additive manufacturing
  • Proficiency with industry-standard FEA tools (e.g., Abaqus, ANSYS) and process-simulation approaches
  • Strong scripting and automation skills (Python recommended) to build repeatable workflows
  • Familiarity with material characterization, constitutive modeling, and experimental validation
  • Experience integrating simulation results into design and manufacturing decision processes
  • Good software engineering practices: version control, reproducibility, and documentation

Responsibilities

  • Develop and maintain FEA and process simulation models (thermal, structural, residual stress, distortion) for metal additive manufacturing processes.
  • Create material models and process-physics representations for powder-bed and directed-energy deposition workflows.
  • Automate simulation workflows and integrate them into engineering toolchains and design review processes.
  • Validate simulation predictions against lab and production test data; iterate models based on experimental results.
  • Collaborate closely with propulsion, manufacturing, materials, and design teams to drive qualification and production ramp.
  • Optimize designs and process parameters for manufacturability, performance, and yield using simulation-led studies.
  • Document methods, results, and assumptions; present findings to cross-functional stakeholders and leadership.

Education

  • Bachelor’s degree in Mechanical, Aerospace, Materials, or related engineering field (required)
  • Master’s or PhD in a related field preferred, especially with relevant simulation research or thesis

Benefits

  • Competitive salary and equity
  • Generous PTO and sick leave policy
  • Parental leave
  • Annual learning and development stipend
  • Comprehensive health and wellness benefits
  • Opportunities for career growth and high-impact work in aerospace
