Job description

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, COMPONENTS TEST (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 Test team develops test and manufacture processes for the most advanced spacecraft components in the world. Our engineers serve as software and hardware experts for the flight control devices and mechanisms that drive the critical capabilities on our satellites - from inertial control devices, to network hardware and more. We design software and build the systems that test the flight components for maximum performance and reliability in extreme environments, with mission success being imperative.
Testing is a fundamental quality check and last line of defense before our products are installed for flight. As a Software Engineer, you will have the unique opportunity to design and develop test software infrastructure that will validate the performance of these components in a cross-disciplinary environment. You will be expected to create new test systems and infrastructure from the ground up including hardware, software, and the interface between the two.
We are looking for people who excel at solving complex problems, maintain a high sense of urgency in their work, and contribute as a team player to build new capabilities and innovate in our testing approach.
RESPONSIBILITIES:
  • Develop modular, reusable test and automation software in Python and similar languages for manufacturing and engineering design verification
  • Write automation software to interact with flight hardware, test equipment, instrumentation, and production documentation systems
  • Develop custom automation solutions to engineering and manufacturing challenges using a combination of embedded electronics and innovative hardware
  • Develop algorithms to analyze complex test data to determine if components have met acceptance criteria
  • Maintain and troubleshoot existing automation infrastructure and work with partner teams to determine and correct root cause of failures
  • Define and implement project plans, manage milestones and hold reviews to assure reliable test systems are delivered to production

BASIC QUALIFICATIONS:
  • Bachelor's degree in computer science, engineering, math, or STEM discipline; OR 2+ years of professional experience in software development in lieu of a degree
  • Development experience in C, C++, or Python; or full stack software development experience

PREFERRED SKILLS AND EXPERIENCE:
  • Extensive knowledge of Linux and Windows operating systems
  • Experience with configuration management and version control software
  • Experience with continuous integration and agile development
  • Experience automating processes and testing to improve manufacturing yields and reduce production time
  • Experience developing application, test, or automation software in an interdisciplinary environment
  • Experience with control feedback loop design and implementation
  • Experience with numerical analysis techniques and signal processing in multiple domains
  • Extensive knowledge with a range of digital and analog interfaces including GPIB, USB, VISA, TCP/IP, VLAN, CAN bus, SPI, I2C, Modbus, analog-to-digital conversion
  • Experience troubleshooting interactions between software and hardware such as network devices and lab instrumentation
  • Experience with spacecraft fluid systems
  • Experience with high power electrical systems
  • Experience with electro-mechanical systems
  • Experience with embedded hardware product development

ADDITIONAL REQUIREMENTS:
  • Willing to work extended hours and weekends as needed
  • 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

COMPENSATION AND BENEFITS:
Pay Range:
Level 1: $125,000.00 - $150,000.00
Level 2: $145,000.00 - $175,000.00
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 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.
