About the role
SpaceXSI is building Super Intelligence to help humanity understand the universe. As a Sr. Software Engineer, Network (C++), you will design, implement, and operate Colossus networking software at scale, optimizing performance, reliability, and latency across vast GPU clusters. You will own the full lifecycle of software—from design through deployment, monitoring, and iteration based on real-world performance.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
