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 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, CORE SERVICES

As a Software Engineer on the Core Services team at SpaceXSI, you'll own the critical shared services that sit between our product surfaces and the infrastructure layer: auth, webhooks, and the backend systems that power agent workflows. SpaceXSI is redefining how developers write code, and your work is what makes that possible at scale. You'll build the systems that every product team depends on, ensuring they are reliable, well-abstracted, and ready for whatever comes next.

RESPONSIBILITIES:

Own authentication: designing and implementing a scalable auth architecture that secures one of the most widely-used developer tools in the world
Powering the agent backend: owning the infrastructure behind Cursor's agent workflows, optimizing for end-to-end performance and reliability as agents become central to the developer experience
Build a robust webhook server: handling high-throughput event delivery with proper retry semantics, dead-letter queues, and observability so external integrations just work
Harden SCM integrations: building resilient abstractions over source control providers so Cursor stays rock-solid regardless of third-party conditions
Drive end-to-end agent reliability: partnering with the client and inference teams to improve the full path from user action to agent response, closing the loop on one of the hardest problems in AI-powered development

BASIC QUALIFICATIONS:

Experience building and operating backend services in production. Experience working with APIs and third-party integrations.

PREFERRED SKILLS AND EXPERIENCE:

Experience with auth systems, API gateways, or webhook infrastructure
Experience working on agentic products or infrastructure and strong opinions on reliability and performance of complex multi-step systems
Care deeply about clean abstractions, well-defined service contracts, and making it easy for other engineers to build on top of your work
Strong software engineering fundamentals and enjoying owning the full lifecycle of production services
Experience with authentication/authorization frameworks (OAuth, JWTs, RBAC), event-driven architectures, or building developer-facing platform services is a plus

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.
