Job description

SOFTWARE ENGINEER (STARSHIELD) - TOP SECRET CLEARANCE

The Starshield mission is to support national security through a focus on timely and reliable information delivery. Our partners in the intelligence community and defense services need best-in-class technology, developed and fielded quickly and iteratively. Our goals are focused on delivering meaningful new capabilities through both new hardware development and continual software innovation.

The Starshield Software team is building software that safely and securely operates our constellation of thousands of satellites. With our focus on national security missions, we are developing novel technologies to secure our networks and data. We are looking for software engineers who are interested in learning about security applications as well as embedded system development to help us innovate.

Software engineers are engaged in every step of the design process for new technologies. We directly maintain our software systems in production whether as part of our distributed ground network or the software flying aboard our satellites. We are looking for engineers who want to write their own code, test their own systems, and have extreme influence over the end outcomes. Aerospace or satellite experience is not required to be successful here - we want engineers to bring fresh ideas from all areas in software. We look for engineers who love solving problems and seek to make an impact on an inspiring mission helping our national security. We are looking for versatile, motivated and collaborative engineers.

RESPONSIBILITIES:

  • Create highly reliable software systems that control thousands of satellites in low earth orbit
  • See your software through from start to finish: from figuring out the core needs to prototyping, developing, and testing; to on-orbit rollout and beyond
  • Work with interdisciplinary teams to brainstorm, design, and build the next generation of satellite capabilities, from cutting-edge sensors and inter-satellite lasers to space-based cloud compute
  • Work directly with end customers to deliver quality products and data to meet their needs

There are several roles within the Starshield software team with different focus areas. Applicants will interview for specific focus areas based on hiring needs and qualifications. Specific role responsibilities may include: 

  • Write high quality Linux-based C++ software for common processors and micro controllers (e.g. ARM, PowerPC, x86, etc.)
  • Develop novel embedded cryptography applications for satellites and ground equipment
  • Develop highly performant networks to connect sensor data to end users
  • Build automated ground-based software systems that integrate smart data processing with command and control of the satellites
  • Develop models and simulations for flight-like vehicle software testing, network performance analysis, or research & development projects
  • Develop tools that allow for test execution across multiple environments: virtualized hardware, real hardware-in-the-loop, and even vehicle-in-the-loop testing

BASIC QUALIFICATIONS:

  • Bachelor's degree in computer science, engineering, math, or scientific discipline; OR 2+years of professional experience insoftware development in lieu of a degree
  • Development experience in C, C++, or Rust
  • Active Top Secret, Top Secret SCI, or DOE Level Q clearance

PREFERRED SKILLS AND EXPERIENCE:

  • Solid fundamental knowledge of computer architecture, networks, debugging, and software testing
  • Ability to work effectively and creatively in a dynamic environment with changing needs and requirements
  • Ability to work independently and in a team, take initiative, and communicate effectively
  • Production experience with containerization technologies (e.g. Docker, Kubernetes)
  • Experience with relational databases (PostgreSQL, CockroachDB, or similar)

ADDITIONAL REQUIREMENTS:

  • 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 testing 
  • Willing to work extended hours and weekends when needed 

COMPENSATION AND BENEFITS:    

Pay Range:    
Software Engineer/Level I: $125,000.00 - $145,000.00/per year    
Software Engineer/Level II: $145,000.00 - $175,000.00/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 and will be eligible for 10 or more paid holidays per year.
