About the Role This is a hands-on software engineering role on the Cloudflare One Appliance team. You will shape and build the Linux-based edge runtime and distributed control plane that connect customer sites to Cloudflare. As a Senior Systems Engineer, you will work across low-level systems, distributed services, and API design while providing technical leadership for major initiatives. Our architecture follows a “light branch, heavy cloud” philosophy: policy and intelligence belong in Cloudflare’s network unless locality is required for correctness, survivability, performance, or user experience. You will use strong technical judgment to decide what belongs to the appliance and what belongs in the Cloudflare's network, building systems that are secure, observable, resilient to partial failures, and safe to operate across a large fleet carrying customer-critical traffic. Responsibilities • Build systems end to end: Design and implement capabilities spanning the cloud control plane, Linux appliance runtime, telemetry pipeline, and physical, virtual, and cloud deployment environments. • Build a Linux-based networking platform: Develop and harden the appliance dataplane. Build secure, reliable networking capabilities using technologies such as IPsec, MASQUE, eBPF, and Linux kernel networking primitives while keeping the system small, predictable, and secure. • Engineer reliable fleet control: Build distributed control-plane and state-management systems that safely deliver configuration and commands, tolerate intermittent connectivity and partial failures, converge to known-good state, and support zero-touch operation across large device fleets. • Secure the device lifecycle: Improve hardware-backed identity, attestation, secure boot, immutable operating-system images, credential rotation, and staged over-the-air upgrades with safe rollback and recovery. • Make operability a product feature: Design telemetry, diagnostics, synthetic tests, support bundles, and remote operations that help customers and support teams understand the system without treating the
