Original 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.

PRINCIPAL SOFTWARE ENGINEER (APPLICATION SOFTWARE)

The application software team is the central nervous system of SpaceX – we create mission critical applications that are used throughout SpaceX to accelerate launch vehicle production and flight as well as systems that allow Starlink to grow into a worldwide fast, reliable Internet service. We are looking for engineers who treat fellow teammates with fairness, respect, and support.

Our team is currently creating and evolving systems to enable rapid build and reuse of Starship as well as designing the next generation manufacturing software that will be used in high throughput factories for Starlink. Other applications range from platforms that support concurrent streams of data from many always-on assets to manage the world’s largest satellite constellation to public facing systems where customers can join our Starlink network globally. We work closely with engineers throughout the company to create and update our systems with respect to crewed launches, Starship flights, changes to the Starlink network and much more.

Aerospace experience is not required to be successful here - rather we look for smart, motivated, respectful, collaborative engineers who love solving problems and want to make an impact on a super inspiring mission. You will have full ownership of challenging problems, working with a team of enthusiastic engineers with diverse perspectives to design and produce solutions that enable SpaceX to move towards our goals at a rapid pace.

Experience working with in-stream data processing using Apache Kafka, RabbitMQ, ActiveMQ, or similar technologies
Production experience with Docker and Kubernetes
Front-end experience in Angular, React, or similar JavaScript framework
Database experience with PostgreSQL, SQL Server, or similar database technologies

ADDITIONAL REQUIREMENTS:

You may be asked to work extended hours/weekends dependent on launch cadence
This role requires you to be onsite. Remote and/or hybrid work will not be considered

COMPENSATION AND BENEFITS:

Pay Range:

Level 3: $210,000.00 - $340,000.00

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.
