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 making life multiplanetary and expanding consciousness to the stars.SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

ABOUT THE ROLE: As part of the Network Software and Services for AI (nssAI) team at SpaceXSI, you'll build cutting-edge software, services, and frameworks to empower our Network Development Engineers. Working hands-on, you’ll tackle all facets of network management—metric collection, configuration, zero-touch provisioning, monitoring, and auto-remediation—driving automation-first solutions for SpaceXSI's production and ancillary networks. Expect to develop extensible tools, streamline complex processes, and ensure rock-solid reliability to support SpaceXSI's mission of accelerating human scientific discovery through AI.

RESPONSIBILITIES:

• Building software and tools with extensive metrics coverage for some of the world’s largest GPU supercomputing network fabrics used for AI training and serving customer inference queries.
• Implement IaC best practices, enhancing deployment pipelines, and ensuring robust, secure service delivery across our production environments.

BASIC QUALIFICATIONS:

• Deep experience collaborating with network engineers daily using extensive knowledge of network topologies, physical and logical, and network protocols.
• Expert knowledge and proven history with designing scalable and reliable software from the ground up that can build and orchestrate tens of thousands of network devices at lightning speeds.
• Ability to thrive in ambiguity, creating metrics that will help prioritize the focus of the team and your own.

COMPENSATION AND BENEFITS:

• €80,000 - 150,000 EUR Base salary is just one part of our total rewards package at SpaceXSI, which also includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, and various other discounts and perks.

SpaceXSI is an equal opportunity employer.
