About Us At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company. At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in. Available Locations: Austin, TX About the role Reporting to the Director of Vulnerability Management, the Lead Vulnerability Management Engineer will serve as the technical authority for the program, focusing on the architecture, systems design, and long-term technology strategy for Cloudflare's vulnerability management capabilities. You will lead the evaluation and integration of advanced security technologies and systems across global infr

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: Join the High Power Engineering team supporting SpaceXSI to design, build, operate, and maintain electrical infrastructure for AI training campuses. As a Lead Engineer for Transmission & Distribution, you will work with a small on-site team to scale high-capacity power systems on a schedule set by compute demand. The position is based in Memphis, TN, with potential travel to other sites. RESPONSIBILITIES: Own everything from generation terminals and the point of interconnection down to the medium-voltage bus: high-voltage switchyards, collector transmission, main power transformers, and the utility relationship that determines whether the campus energizes on schedule. Own high-voltage switchyard architecture: bus configuration, GIS versus AIS tradeoffs, bus sectionalizing, and fault-current management. Lead the interconnection process with the local distributor and balancing authority, including application, system impact and facilities studies, protection philosophy alignment, telemetry and metering, and technical exhibits to the service agreement. Own campus protection philosophy and the settings management database served to Data Center and Battery Storage

The position is based in Memphis, TN, with potential travel to other sites. RESPONSIBILITIES: Own the electrical architecture from the medium-voltage bus to the GPU rack — topology, redundancy, and standards — for halls scaling with AI compute load. Set and defend the redundancy basis; prove split-feed and cross-feed schemes against bus-fault, transformer-loss, and switchgear-loss contingencies. Establish the campus electrical design standard: equipment tagging, drawing conventions, approved vendor list, insulation coordination, grounding, and arc-flash boundaries. Own the interface with the compute organization on rack density, step-load behavior, power-capping strategy, and actual-versus-nameplate utilization. Own the interface with mechanical and cooling engineering on CDU, sidecar, and pump electrical loads and their contribution to hall demand. Lead desi

The position is based in Memphis, TN, with potential travel to other sites. RESPONSIBILITIES: Own the storage fleet as a power plant, not as an accessory: architecture, sizing, controls, safety case, and grid-forming behavior that lets the campus ride through compute step loads and generation contingencies. Own BESS architecture: pack-to-MV-transformer grouping, string composition, medium-voltage collection topology, string-level protection, and physical block layout including spacing per NFPA 855. Own sizing; translate compute duty cycles — step loads, training-job ramps, actual-versus-nameplate utilization — into power and energy requirements. Own inverter control strategy: grid-forming versus grid-following, droop and virtual inertia, fault-current contribution, ride-through, and coordination with generation governors and excitation. Own the plant controller and
