DESCRIPTION
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.
Key job responsibilities
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.
About the team
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.

What Employers Look For
The qualifications that appear most often in core network engineer jobs.
- Deep hands-on experience with BGP, OSPF, or IS-IS in large-scale production environments
- Proficiency with Cisco IOS/IOS-XR or Juniper Junos on carrier or enterprise core platforms
- Strong understanding of MPLS, traffic engineering, and VPN architectures
- Bachelor's degree in computer science, electrical engineering, or a related field
- CCIE, JNCIE, or equivalent vendor certification strongly preferred or required
- Experience with network automation tools such as Ansible, Python scripting, or NETCONF/YANG
Tips for Your Core Network Engineer Job Search
Tailor your resume to vendor ecosystems
Hiring managers in core networking scan for Cisco, Juniper, or Nokia experience before reading anything else. List your vendor platforms, specific IOS or Junos versions, and the scale of networks you've operated, not just generic routing protocol names.
Lead with protocol depth, not breadth
Listing every protocol you've touched dilutes your resume. Pick the two or three where you have real production depth, such as BGP policy design or MPLS-TE, and frame them around the problems you solved and the network scale involved.
Apply early to roles that fit
Migrate Mate lists core network engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Filter openings by infrastructure type
Carrier-grade and enterprise core networking use different toolchains and interview styles. When searching, look for signals like 'service provider,' 'backbone,' or 'WAN architecture' in job descriptions so you're targeting roles where your specific experience is directly relevant.
Prepare a whiteboard-ready network design
Most core network engineer interviews include a live design exercise. Practice walking through a redundant backbone topology out loud, explaining your choices for convergence, failure isolation, and traffic engineering before you're in the room.
Negotiate on-call scope before accepting
Core network roles often carry 24/7 escalation responsibilities that vary dramatically by team. Clarify during offer discussions which tier of incidents you own, how often you're primary on-call, and whether there's a rotation, so there are no surprises after you start.
Core Network Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most core network engineers?
The most active employers for core network engineers right now are Amazon, Feuji, and OpenAI, and the most openings are in Washington, Texas, and Virginia, based on current listings on Migrate Mate as of November 2026. Telecommunications carriers, cloud infrastructure providers, and large defense contractors tend to post the highest volumes consistently.
How many core network engineer jobs are remote?
About 50% of core network engineer openings are fully remote or hybrid as of November 2026, though fully on-site roles remain common for positions involving physical hardware, lab work, or classified environments. Network automation, planning, and architecture sub-roles tend to have the highest remote availability within the discipline.
How do you become a core network engineer?
Start with a foundation in networking fundamentals and earn an associate-level vendor certification such as CCNA or JNCIA. Build hands-on experience with routing protocols and switching in a lab or entry-level network operations role. Progress to production support on backbone or WAN infrastructure, then pursue a professional or expert-level certification like CCNP or CCIE to qualify for senior core network positions.
How do you get hired as a core network engineer with little experience?
Focus on roles titled network operations engineer or NOC engineer that expose you to production routing environments. Build a home lab running BGP and OSPF across virtual routers to demonstrate protocol knowledge. Earning a CCNA or equivalent certification signals seriousness to hiring managers who would otherwise filter out candidates without direct core networking experience on their resume.
What does the core network engineer interview process look like?
Most processes start with a recruiter screen, followed by a technical phone interview covering routing protocols, failure scenarios, and troubleshooting methodology. A live or take-home network design exercise is standard for mid-level and senior roles, often involving MPLS or BGP topology design. Final rounds typically include a panel of senior engineers and may involve a lab practical at larger carriers.
Where can I find and apply to core network engineer jobs?
You can find and apply to core network engineer jobs on Migrate Mate, which lists current openings from employers across the United States. Search for roles that match your vendor experience, protocol focus, and seniority level, then apply directly to each listing that fits.
