The posting

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.

SOFTWARE ENGINEER, INFRASTRUCTURE

As a Software Engineer on the Infrastructure team at SpaceXSI, you'll own the foundational cloud and networking layer that every service runs on: network foundations, container orchestration, edge and security infrastructure, and the compute runtimes that power production. SpaceXSI is one of the fastest-growing developer tools in the world, and you'll drive the cost management, regional deployment strategy, and infrastructure unification that make that growth possible. When your systems work well, every team is more productive, every product surface is more reliable, and Cursor can expand to serve developers everywhere.

RESPONSIBILITIES:

- Own Kubernetes and cluster foundations: building and operating production clusters with proper service mesh, scaling, and ingress that teams can confidently deploy to

- Design the geo-deployment architecture: building a replicable, robust process for deploying geo-replicated services across cloud regions and providers

- Build edge and security infrastructure: designing the networking and security layer at the edge to protect against abuse, manage rate limiting, and optimize traffic routing

- Own cost management and optimization: building attribution systems, identifying waste, and ensuring we're making smart tradeoffs between cost and reliability across all cloud spend

- Unify the compute platform: defining a single, opinionated container orchestration strategy so every team gets consistent, reliable deployments out of the box

BASIC QUALIFICATIONS:

Experience building and operating infrastructure on AWS, GCP, or similar cloud platforms.

PREFERRED SKILLS AND EXPERIENCE:

- Kubernetes experience at scale, including service mesh, autoscaling, and multi-region deployments

- Experience building and operating production Kubernetes clusters at scale, including service mesh, autoscaling, and multi-region deployments

- Understand edge networking, CDN/WAF architectures, and traffic management at the infrastructure level

- Care about infrastructure-as-code, reproducibility, and making it easy for other teams to self-serve reliable infrastructure

- Experience with cost optimization at scale or infrastructure migration/unification is a plus

- Strong software engineering fundamentals and enjoying building the platform that makes every other team faster

ADDITIONAL REQUIREMENTS:

- If there appears to be a fit, we'll reach out to schedule 2-3 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team

COMPENSATION AND BENEFITS:

The annual compensation range for this role is listed below.

Annual Salary:

$140,000 - $225,000 USD

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 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
