The opportunity

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.

What you'll do

  • 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 appliance as a black box.

  • Drive customer-centered product decisions: Work with customers, Product, Support, and Solutions Engineering to understand customer requirements and turn them into pragmatic technical direction. Bring clear opinions, and revise them when customer feedback or production evidence points to a better answer.

What they're looking for

  • Own production outcomes: Prototype quickly, ship in safe increments, and own rollout, monitoring, incident follow-up, and long-term maintainability.
  • Lead across teams: Set architectural direction for major initiatives, write clear technical proposals, conduct rigorous reviews, and mentor other engineers. Build executable plans with Cloudflare WAN, Gateway, DEX, the Cloudflare One Client, and platform and security teams.
