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, HARDWARE TEST AUTOMATION (STARLINK)

As a Software Engineer on the Starlink Team, you will design software and build systems that test flight components and entire satellites for maximum performance and reliability in extreme environments, with mission success being imperative. Your focus will be on developing the automation and software solutions for the components and platforms that bring the Starlink Satellite to life. Our software engineers are responsible for the tools that enable rapid development and accurate testing of all Starlink hardware systems, with a continual focus on design, reliability, and innovation, from test hardware system designs to our software infrastructure. Our engineers serve as the experts for the flight control devices and mechanisms that drive the critical capabilities on our satellites - from inertial control devices to space lasers and more.

Aerospace experience is not required to be successful here – engineers on this team are curious, and collaborative, love to learn new things, and work effectively in a dynamic environment to deliver high-impact technology on a massive scale.

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 software that allows for test execution across multiple environments: hardware-in-the-loop (HITL, HIL) and virtualized hardware simulations

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

Invent tools that enable more frequent and reliable software deployment, test execution, and data analysis as part of a continuous integration and release system

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 Python and/or C, C++
