Software Engineer, Flight Software C++ (Starshield)

Spacex
Hawthorne, CA

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, FLIGHT SOFTWARE C++ (STARSHIELD)

Starshield leverages SpaceX’s Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads.

The Starshield software team is building highly reliable in-space mesh networks, designing secure systems to guarantee access to space, designing next-gen communication and sensing software, and more. Aerospace experience is not required to be successful here - we want our engineers to bring fresh ideas from all areas. We look for engineers who love solving problems and seek to make an impact on an inspiring mission. As we expand this team, we're looking for versatile, motivated, and collaborative engineers.

Our team is involved in designing the vehicle systems at every phase of development. We build tools that enable us to work more efficiently, and that help us build software systems that are secure, reliable, and autonomous. Our software engineers are responsible for the life cycle of the software they create, including development, testing, and operational support.

RESPONSIBILITIES:


  • Develop highly reliable autonomous software systems, and the full suite of testing needed to ensure their resilience, fault tolerance, and correctness

  • Design software for both vehicles flying in space, and the ground systems that support them

  • Build prototypes and analyze system metrics to prove out key design concepts and quantify technical constraints

  • Own all aspects of software development, including design, testing, release, and flight operations

  • Provide strong technical leadership, focus on continuous improvement

BASIC QUALIFICATIONS:


  • Bachelor's degree in computer science, engineering, math, or scientific discipline; OR 2+ years of professional experience in software development in lieu of a degree

  • Development experience in C or C++

PREFERRED SKILLS AND EXPERIENCE:


  • Experience with embedded systems (e.g. STM32, Arduino, or similar microcontrollers) and low level firmware development

  • Strong knowledge of linux internals including core platform and user-space application development/debugging

  • Experience designing fault tolerant, distributed, or real-time systems

  • Cross-context test design skills, ranging from simple unit tests through to integrated hardware-in-the-loop regression and exploratory tests

  • Knowledge of computer architecture and networks

  • Knowledge of physics, math, and electronics

  • Experience in debugging, performance optimization, and performance testing

  • Ability to work effectively in a dynamic environment with changing needs and requirements

  • Ability to work independently or in a team, take initiative, and communicate effectively in a solution-oriented manner

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

  • Must be willing to work extended hours and weekends 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 and will be eligible for 10 or more paid holidays per year.
