Cloudflare - Technical Support Engineer Intern (July to December 2026)
Requirements
• Systems Leadership: 5+ years of experience managing engineering teams, ideally in low-level systems, kernel development, or large-scale infrastructure environments. • Systems Leadership: • Low-Level Expertise: A deep understanding of Linux Kernel internals, x86/ARM architecture, and OS design fundamentals. You should be comfortable discussing memory management, schedulers, and network stacks. • Low-Level Expertise: • Automation Mindset: Experience building or managing CI/CD pipelines for foundational software. You believe that "toil" is a bug and automation is the feature. • Automation Mindset: • Open Source Pedigree: A proven track record of engaging with the open-source community. You understand the nuances of upstreaming and how to navigate community dynamics effectively. • Open Source Pedigree: • Operational Empathy: An understanding of the unique challenges of a global "reboot-limited" production environment. You prioritize stability and have experience with pre-production QA and synthetic workload evaluation. • Operational Empathy: • Strategic Communication: The ability to translate complex kernel-level obstacles into actionable business insights for stakeholders across the company. • Strategic Communication: • Resilience: You aren't intimidated by the "impossible." Whether it's a non-reproducible race condition or an unwelcoming upstream thread, you lead your team through the challenge with a pragmatic, solution-oriented mindset. • Resilience: • What Makes Cloudflare Special? • We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet. • Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost. • Project Galileo • Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states. • Athenian Project • 1.1.1.1 • Sound like something you’d like to be a part of? We’d love to hear from you! • This position may require access to information protected under U.S. export control laws, including the U.S. Export Administration Regulations. Please note that any offer of employment may be conditioned on your authorization to receive software or technology controlled under these U.S. export laws without sponsorship for an export license.
Responsibilities
• Lead and Mentor: Manage a high-performing team of kernel and systems engineers, fostering a culture of "collaboration-first" and continuous knowledge sharing both internally and with the global open-source community. • Lead and Mentor: • Own the OS Lifecycle: Oversee the end-to-end delivery of the Linux Kernel and core OS components. Your goal is a fully automated continuous delivery pipeline that moves from merge to 100% production in less than 30 days. • Own the OS Lifecycle: • Drive Technical Vision: Steer the Cloudflare kernel development roadmap. You will balance the need for cutting-edge features with the absolute requirements of production stability, security, and performance. • Drive Technical Vision: • Upstream Advocacy: Promote a "minimal patch" philosophy by ensuring your team is a top contributor to the Linux Kernel. You will support engineers in becoming upstream maintainers for critical subsystems. • Upstream Advocacy: • Cross-Functional Collaboration: Act as a consultant to hardware and service teams, helping them onboard new hardware and optimize workloads for our OS. You’ll lead a "virtual team" environment where any engineer at Cloudflare can contribute to the kernel. • Cross-Functional Collaboration: • Innovate Debugging: Tackle the "impossible" challenges of kernel-level debugging. You will lead the development of automated systems that collect critical telemetry when a system crashes, even when traditional debuggers cannot run. • Innovate Debugging: • Measure Success: Use DORA metrics and team-specific capabilities - such as the "time to fix a kernel issue" and upstream commit volume - to track and improve team impact. • Measure Success:
