About this Software Engineer - Platform Security role at xAI

xAI · Onsite · Palo Alto, CA

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:

We are seeking a talented and driven Software Engineer to join Platform Security team, where you will build cutting-edge security solutions to protect our Kubernetes-based infrastructure and advance secure AI-driven systems. In this role, you will design and implement AI-powered security tools, proactively address vulnerabilities, and champion secure engineering practices across the organization. Ideal candidates are passionate about impactful innovation, excel at writing clean, efficient code, and thrive in fast-paced environments to support SpaceXSI's mission of creating a trusted and secure global digital platform.

RESPONSIBILITIES:

  • Design and build AI-driven security tooling and agents using Grok to identify, analyze, and mitigate vulnerabilities in the platform infrastructure and customer facing application(s)
  • Proactively identify security problems to solve and own the design and implementation end-to-end
  • Collaborate and be a security champion while driving technical decisions across the organization

BASIC QUALIFICATIONS:

  • 3+ years of experience in fast-paced, high-impact environments, ideally at startups or tech-driven companies.
  • Expertise in Python, Rust, or Go, with strong problem-solving skills and a focus on clean, efficient code.
  • Certifications like CISA, CRISC, CGEIT, Security+, CASP+, or similar preferred.
  • Proven experience building tools or systems from scratch, with a focus on scalable solutions.
  • Proficiency in designing scalable backend architectures to support secure systems.
  • Familiarity with security testing frameworks (e.g., Burp Suite, OWASP ZAP, SAST/DAST).
  • Experience with Docker and Kubernetes for deploying and securing containerized applications.
  • Knowledge of software supply chain tools, including SBOM management and dependency scanning.

PREFERRED SKILLS AND EXPERIENCE:

  • Experience developing AI-driven security tools or integrating AI into security workflows.
  • Familiarity with Kubernetes-based environments and securing cloud-native infrastructure.
  • Proven ability to drive technical decisions and influence security practices across teams.
  • A passion for challenging the status quo and building transformative security solutions.
  • Strong collaboration skills, with experience working in dynamic, cross-functional teams.
  • A sense of humor and adaptability to thrive in a fast-paced, mission-driven environment.

COMPENSATION AND BENEFITS:

$100,000 - $258,000 USD

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.
