Software Engineer - Simulation & Flight Systems

SOFTWARE ENGINEER - SIMULATION & FLIGHT SYSTEMSAs a Software Engineer in Special Programs, you’ll design, develop, and own critical software that powers the exploration and validation of next-generation technologies across every SpaceX flight system. You’ll take full ownership of new features in a scalable, high-performance application that spans the entire design-build-test-operations pipeline, while also contributing to critical control and flight system software. Your work will directly expand our capabilities in both ground and space systems and help prove out the innovations that make multiplanetary life possible.This is a high-impact role where you’ll collaborate across engineering teams to build a high-throughput distributed system that develops and demonstrates cutting-edge software and hardware. The systems you create will be used by engineers pushing the limits of what’s possible-your code will help fly rockets, test vehicles, and shape the future of spaceflight.Aerospace experience is not required. We’re looking for exceptionally smart, motivated software engineers who thrive on complex challenges, move fast in dynamic environments, and care deeply about software craftsmanship. Our software is mission-critical, and we have no shortage of hard, interesting problems that demand creative, high-quality solutions.RESPONSIBILITIES:Rapidly develop prototypes that prove key design concepts and quantify technical constraintsDevelop high-performance modules for real-time flight systems data streamingContribute to test automation processes and CI/CD infrastructureCreate and maintain high-fidelity simulation and flight software for all vehiclesContinually raise the bar for excellence through improving the reliability, performance, and scalability of our simulation and flight platformsPartner closely with engineers and customers to design and deliver new features that dramatically improve system capabilities and performanceBASIC QUALIFICATIONS:Bachelor’s degree in computer science, engineering, math, or science discipline and 1+ years of experience in software development; or 3+ years of professional experience building software in lieu of a degreeProfessional experience with systems programming languages such as C++, Rust, or GoPREFERRED QUALIFICATIONS:Strong software design and development skillsExperience with data streaming and real-time data processingExperience with data serialization formats such as JSON, YAML, XML, or ProtobufExperience delivering robust and scalable software applicationsExperience with Python, Java, or C#Experience with containerized solutions such as Docker and KubernetesExperience with relational databases (SQL, PostgreSQL, MySQL, or Oracle)Strong skills in debugging, performance optimization, data throughput analysis, and unit testingStrong creative and innovative problem-solving skillsAbility to work effectively in a dynamic environment by quickly adapting to changing needs and requirementsActive Top Secret, Top Secret SCI, or DOE Level Q clearance, or the ability and willingness to obtain oneADDITIONAL REQUIREMENTS:This position requires successfully obtaining and maintaining a Top Secret Security Clearance as a condition of employment. While the clearance may not be immediately necessary upon hire, we encourage you to initiate the application process promptly upon accepting this offer. Your ability to secure the necessary clearance is essential for fulfilling key responsibilities of the role. Should you be unable to obtain it, SpaceX reserves the right to modify or terminate your employment to align with operational needs.Note that an active clearance may provide the opportunity for you to work on sensitive SpaceX missions; if so, you will be subject to pre-employment drug and random drug and alcohol testAble to work extended hours and weekends when necessary to support proposal or critical project timelinesCOMPENSATION AND BENEFITS:Pay Range:Level 1: $125,000.00 - $160,000.00Level 2: $145,000.00 - $195,000.00Your 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 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 and will be eligible for 10 or more paid holidays per year. Employees accrue paid sick leave pursuant to Company policy which satisfies or exceeds the accrual, carryover, and use requirements of the law.Those with an active clearance will receive a 10% differential, up to an additional $20,000 annually, once officially briefed into a classified program.
