As a Network Development Engineer II in Seattle, you'll work on several Senior Leadership initiatives at once.
MONA builds and operates the management plane, out-of-band (OOB) network, and automation systems that keep AWS's global network running. We run one of the largest fleets in Networking, growing from about 545K to 985K devices by the end of 2027, and we are redesigning the control layer underneath it. That means building the next generation of management networks for AWS, designed for Resilient Network Graphs (RNG), Machine Learning, and Intent-Driven Controls. We use software and AI, not manual process, to solve problems that people, runbooks, and tickets have solved until now.
As a Network Development Engineer II in Seattle, you'll work on several Senior Leadership initiatives at once. They include One Management Network, the next generation of how we build management connectivity across the fleet; faster on-site server builds; Initial Access, our new satellite-based product that supports multiple organizations in parallel and cuts the time to bring a new data center online; and support for new EC2 and security requirements. You'll join a team of network and software engineers working side by side, and you'll build and own pieces of this work from design through to launch. We want engineers who see a recurring network problem and build a product to solve it, not just a fix.
Network Development Engineers in MONA build and operate the software and network systems that manage AWS's global network. You will design, deploy, scale, and sustain management plane, out-of-band, and automation platforms. You will use AI to troubleshoot and automate network operations, and you will write the documentation that lets others run what you build.
Design, build, and operate production automation and controller software that detects, diagnoses, and remediates network faults without manual intervention.
Use AI to automate repetitive operational work. Identify recurring network problems and turn them into reusable products, tools, and agentic workflows instead of one-off fixes, runbooks, or tickets.
Own projects from design through to operation in areas such as device management, out-of-band connectivity, Initial Access, network deployment and scaling, technology refresh, and sustaining engineering.
Make and implement changes on the network safely, using tooling, testing, and staged rollouts.
Work closely with software engineering and automation teams to define the tools and controllers that let us scale to a much larger fleet with a smaller team.
Use AI to troubleshoot network issues faster. Diagnose, mitigate, and resolve large-scale network events that affect significant AWS customers, using AI to triage, correlate alarms, and find root causes. Work with the highest-tier escalation engineers and resolvers, and drive root cause analysis and corrective actions through to completion.
Troubleshoot routing, interconnectivity, platform, performance, and configuration issues from Top of Rack to the network border. This includes low-level application behaviour, Unix systems, and modern network software tooling.
Partner with network engineering, hardware, and infrastructure teams on designs, configuration standards, and tooling. Make sure new designs and products roll out quickly and smoothly.
Maintain standards across the network toolset, and ensure our systems comply with those standards and policies.
Use operational data to find the largest sources of manual work and device downtime, and prioritise engineering effort against them, including out-of-service targets.
Deliver simple, sustainable, and repeatable solutions and processes. Convert standard operating procedures and runbooks into automated, AI-driven workflows, with guardrails, validation, and human review where the risk calls for it.
Take part in on-call, and reduce its load by cutting alarm noise and using AI and automation to handle common responses.
Write and review design documents, operational procedures, runbooks, and knowledge transfer material. Use AI to draft and update this material, and check it for accuracy before it is used.
A day in the life
Your day might start with a design review for a new controller, or a sync with the team on a workflow you're building. Mid-morning you could be debugging a stuck device in the out-of-band network, using AI to triage alarms and find the cause. Afternoons go to building: turning a recurring ticket into an automated workflow, testing it, and rolling it out in stages. You'll work with software engineers, hardware teams, and escalation resolvers, and write up what you learn so others can reuse it. Some days include on-call.
MONA sits inside AWS Network Fabric Engineering (NFE) and owns the management plane, out-of-band networks, and automation that keep AWS's global network running. You'll join a Seattle team that is part of a global group with hubs in San Jose, Sydney, and Dublin. Network and software engineers work side by side on the same problems, and you will learn from both. The fleet is growing from 545K to 985K devices by the end of 2027. Our work is moving from keeping that growth operable to redesigning the control layer beneath it, using software and AI to replace manual process.
