About the role

Hiring Principal Engineers and Senior Principal Engineers to join AWS Network Services. Work at the intersection of distributed systems, protocols, hardware, security, and production-grade infrastructure that powers global workloads. Lead technical direction, own architectural decisions, and shape products that underpin AWS connectivity and related services.

Responsibilities

  • You will work at the intersection of distributed systems, protocols, hardware, and security, and every system we ship goes straight into production, powering the world’s most demanding workloads.
  • You won't be tuning knobs on an existing system. You'll be deciding what the system is. As a Principal or Senior Principal Engineer, you'll set the technical direction for the systems that make AWS possible where microseconds matter and billions of dollars of customer workloads depend on your decisions.
  • Here, great products start with Engineering. Principal Engineers work in close partnership with Product Management. You’ll propose new products born from deep technical insight and help shape and sharpen ideas. The roadmap grows with its Principal Engineers, so the systems you invent become the products customers rely on.
  • Among the areas we’re hiring for today: - Compute Connectivity: Deliver scale, security, and simplicity. - Real-Time Media: Build infrastructure for sub-second, bidirectional video/audio at global scale. - Security & Threat Defense: Innovate across traffic classification, adversarial defense, and application protection. - Moving the Bytes that Move the World: AWS connectivity solutions powering large customers and governments. - VPC Core — Cross-Plane Networking Architecture: Turn customer and AWS-service intent into working network state across planes and ensure scalable, reliable evolution.

Qualifications

  • 15+ years of professional software development experience
  • Experience owning technical architecture, end-to-end delivery, and partnering with senior leadership
  • Track record of leading multiple concurrent technical initiatives and driving decisions across organizational boundaries
  • Experience influencing VP/SVP-level technical and business strategy
  • Deep expertise in at least one domain: real-time transport protocols (WebRTC, QUIC), DNS, distributed systems, network architecture, web security, game backend systems, large-scale packet processing, or cloud virtual networking and data-plane systems (e.g. VPC-style resource/distribution control, SmartNIC/DPU or Nitro-class pipelines)
  • Strong programming skills in C/C++, Rust, Go, or Java
