Software Engineer, Numerical Modelling

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

SOFTWARE ENGINEER, NUMERICAL MODELLING

As a software engineer on the Numerical Modelling team, you will develop and maintain in house multi physics simulation engine to support multiple manufacturing processes at SpaceX. This role requires strong software development experience, including C++ and Python. This enables our partner teams to accelerate their production rates and improve the quality of resultant parts to push the boundaries of manufacturing for Raptor, Starship, Starlink, and other programs at SpaceX. The team consists of world class experts in solidification physics, casting, metallurgy, and simulation. Experience with casting or solidification is not required – just a desire to learn, collaborate, and enable the best future for manufacturing at SpaceX.  

RESPONSIBILITIES:  

• Own software architecture and quality of simulation software used across SpaceX 
• Develop and optimize next generation software that integrates CFD tools, meshing software, and CAD platforms for multi physics simulations
• Build advanced interfaces for viewing and interpreting simulation results 
• Troubleshoot and debug issues related to software integration, meshing quality, and simulation accuracy 
• Leverage machine learning and AI for faster and more efficient simulations 
• Collaborate with cross-functional teams to implement new features and automate processes
• Conduct testing and validation of simulation results using industry-standard benchmarks

BASIC QUALIFCATIONS:  

• Bachelor's degree in computer science, engineering, math, or STEM discipline; OR 5+ years of professional experience building software in lieu of a degree
• 2+ years of software development experience
• 1+ years of experience with C++
• 1+ years of experience leveraging Python for data analysis

PREFERRED SKILLS:  

• Experience working with numerical solvers for complex physics domains 
• Strong meshing skills for complex simulations
• Ability to apply machine learning and artificial intelligence models to simulations 
• Experience with web development frameworks such as Flask, SQLAlchemy, and FastAPI
• Front-end experience in React or similar JavaScript UI frameworks
• Database experience with PostgreSQL, SQL Server, or similar database technologies
• Good understanding of version control, testing, continuous integration, build, deployment, and monitoring
• Strong Linux experience  
• Knowledge of high-performance computing (HPC) environments and parallel processing
• Strong problem-solving abilities and attention to detail for optimizing simulation efficiency
• Excellent communication skills for documenting code and collaborating in team settings

ADDITIONAL REQUIREMENTS:

• Ability to work extended hours and weekends as necessary
• Ability to travel to other SpaceX sites as needed

COMPENSATION AND BENEFITS:    
    
Pay range:    
Software Engineer/Level I: $120,000.00 - $145,000.00/per year    
Software Engineer/Level II: $140,000.00 - $170,000.00/per year    
    
Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.

Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short and long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation
