At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low‑cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role is part of the Blue Origin Engines business unit, where our focus is the design, development, manufacturing, and testing of engines and propulsion systems. Built for multiple uses, our family of engines is powering the next generation of rockets for commercial, civil, national security, and human spaceflight.

As a Software Engineer in the Scientific Computing team, you will build the computational solvers and infrastructure that enable our engineers to push the boundaries of rocket engine design and analysis.

• Develop and maintain solvers and infrastructure supporting engineering design, analysis, and test workflows.
• Gather project requirements from engineering teams.
• Plan roadmaps for development projects and communicate progress to stakeholders.
• Establish CI/CD pipelines, automated testing, and documentation for all delivered tools.
• Create APIs for seamless integration with commercial and internal analysis products.
• Implement numerical methods for engineering simulation and analysis.

• Minimum of a B.S. degree in aerospace, mechanical, or related engineering discipline.
• 5+ years of professional experience developing software for analysis.
• 3+ years of experience in one of the following areas:
  • Structural analysis techniques (loads, dynamics, FEM, or fatigue)
  • Fluids modeling techniques (FVM, LES, RANS, reacting flows, etc.)
  • Systems engineering analysis (Optimization, Monte Carlo, etc.)
• Strong proficiency in Python or Julia for scientific computing.
• Experience with at least one compiled language used for scientific computing, such as Fortran, C, C++, or Rust.
• Demonstrated ability to gather requirements and deliver technically complex solutions.
• Ability to work independently while contributing to team objectives.
• Strong written and verbal communication skills.

• M.S. or Ph.D. in aerospace, mechanical, or related engineering discipline.
• 2+ years of experience working with FEM software (Nastran, Ansys, Abaqus, LS-Dyna, Opti Struct, NASGRO, etc.).
• Experience with CFD software (ANSYS Fluent, Star‑CCM+, OpenFOAM, etc.) or chemical kinetics tools.
• Experience with systems modeling tools (Model Center, Matlab/Simulink, Python‑based frameworks).
• History of working with CI/CD pipelines and automated testing.
• Experience developing or modifying physics‑based solvers (FEM, CFD, or systems models).
• Familiarity with rocket engines and analysis in challenging environments.
• Experience with generative AI, LLMs, or other AI‑assisted workflow acceleration.
• Experience designing and deploying cloud‑based infrastructure (AWS, Azure, GCP).
• Familiarity with container orchestration (Kubernetes) or HPC schedulers (SLURM, PBS).
• Web application development experience (React or Angular frameworks).
• Experience with SQL and data engineering.
• Familiarity with RESTful API design and microservices architecture.
• Familiarity with version control (Git, SVN) and collaborative development workflows.
• Experience working in an agile environment.
