Job description
Are you ready to build the systems that power one of the largest cloud platforms in the world? Developers everywhere rely on Amazon Web Services for storage, compute, and virtualized services, and our success depends on world-class network and server infrastructure operating at massive scale with rapid integration of emerging technologies. We're looking for a Senior System Development Engineer to develop automated test systems for the networking products that form the building blocks of Amazon's cloud infrastructure.
AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure — in other words, we keep the cloud running. We support every AWS data center and
all of the servers, storage, networking, power, and cooling equipment that give our customers continual access to the innovation they rely on. We work on the hardest problems, with thousands of variables impacting the supply chain, and we're looking for talented people who want to help solve them.
You'll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, and operations managers. You'll collaborate with people across AWS to deliver the highest standards of safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers — all within an inclusive culture that welcomes bold ideas and empowers you to own them to completion.
As a Senior System Development Engineer in Networking, you'll have a unique opportunity to shape the development of our network — a fundamental contributor to the success of AWS that lets us scale existing services and launch new ones. The Release Engineering and System Test organization owns end-to-end, system-level qualification of platforms and OS, the final gate before software is released to production. In this role, you'll build autonomous test systems that qualify new platforms and releases at scale.
This is a hands-on builder role at the intersection of software engineering, test infrastructure, and network systems. You'll develop production-quality automated test systems, integrate them with lab and orchestration services, and drive the reliability, efficiency, and operability of the qualification pipeline that every release depends on. You'll relentlessly improve the stability of the existing network by developing test automation for new hardware and software platforms, working closely with our Network Engineering teams to understand features and technical implementation and to build test suites that emulate real-world environments.
The ideal candidate has spent time in a similar role. Experience with industry-leading automation and CI/CD tools and with IXIA traffic generators (or similar) is a distinct advantage. You strive for simplicity and demonstrate significant creativity and high judgment. Your expertise is both deep and broad — you're hands-on, producing detailed technical work as well as high-level systems architecture.
Key job responsibilities
- Design, build, and maintain automated test systems that scale across platforms and network roles and operationalize qualification suites in CI and nightly regression pipelines
- Integrate test systems with lab infrastructure and orchestration services for device lifecycle management
- Own the reliability and maintainability of your components — eliminate flakiness, drive down qualification runtimes, and continuously improve the reliability of the test systems
- Show creativity and initiative to improve product test coverage and effectiveness
- Debug complex, cross-layer failures spanning test infrastructure, software, hardware and and drive root-cause analysis
- Partner with software, hardware and networking teams release engineering teams to simulate complex real world network designs
- Raise the engineering bar through design reviews, code reviews, and mentoring of junior engineers.
