Senior Network Development Engineer


Dublin, Ireland


The AWS Networking organization is hiring, and we’re looking for great Network Development Engineers (NDE) to join our team. Within Networking, we’re confronting and solving complex and high-stakes challenges. Our teams support all aspects of connectivity to/from Amazon and the outside world, as well as the connectivity between Amazon’s data centers and services. As a member of one our network engineering teams, you will play a part in designing and architecting networks that simply cannot fail, must scale infinitely, and can never constrain growth or innovation.

For this role, we are seeking Network Development Engineers to work in our Internet Services organization. This team is responsible for designing the networks that directly connect Amazon to the outside world (including the Internet, peers, and external customers), evolving the global backbone that interconnects our Regions as well as partnering with our internal customers. Engineers in this organization define routing policy, design and implement Traffic Engineering solutions, as well as architect the hardware platforms and network design to support internal and external connectivity. We move terabits of traffic in and out of our networks each day. The Internet Services team is responsible for the ingress point of all traffic arriving to Amazon, the egress point for traffic leaving as well as the entirety of both our internal and customer traffic that rides our global backbone.

The ideal candidate for this team would have a background in designing and implementing routing protocols such as BGP, MPLS, ISIS and OSPF. Particularly attractive candidates would be from ISP, peering and exchange, and large (IP) carrier network backgrounds. We’re interested in engineers with experience having designed, operated, and implemented networks of very large scale, and those well versed in the operation of the Internet routing hierarchy. Candidates should understand the theory behind and have deep operational knowledge of routing protocols with particular emphasis on their impact to hardware platforms. We’re looking for those who have pushed platforms to their limits, understand how to work within the limitations imposed by third-party software and how to avoid them through your designs.

Experience managing large projects to completion is a must, either as project manager or lead. NDEs are expected to self-manage several projects at a time, providing regular status updates and identifying and pushing through obstacles. It's important to be cross-disciplinary and accustomed to "reaching across the aisle", as you will be working with many hardware, software and customer organizations across Amazon translating customer and business requirements into actual technical solutions.

As a Network Development Engineer at Amazon, your core job responsibility is to design network topologies, architectures, and services that solve for many requirements. Together, you and your leadership team will decide on the projects that best support your team’s mission. This takes the form of creating and defending High Level Design (HLD) documents, working with vendors or internal stakeholders to influence technology roadmaps, constructing and testing your solutions, and providing support to the teams that will deploy and operate these designs.

Amazon is an Equal Opportunity-Affirmative Action Employer – Minority / Female / Disability / Veteran / Gender Identity / Sexual Orientation.


· A Bachelor's Degree in Computer Science or equivalent experience is mandatory.
· In-depth knowledge of and experience with major internet routing protocols; specifically BGP (confederations and complex route reflector topologies), OSPF, MPLS, RSVP and ISIS
· Understanding and experience with Internet peering ecosystems and Internet scale traffic engineering is a must
· In-depth knowledge of and experience with major router platforms; specifically with Juniper MX, EX, and T-series platforms including all compatible processors and line cards for these platforms.
· Excellent network analysis fundamentals and robust troubleshooting skills.
· Troubleshooting traffic engineering using BGP and large scale network design and maintenance is critical.


· Candidates should have a minimum of 5 years industry experience in a similar environment.
· Background in high availability, global backbone design and architecture is highly preferred
· Understanding of Hardware Load Balancers in a large data center environment
· Expert-level certifications (e.g. CCIE, JNCIE) a huge plus.
· Strong Unix skills and the ability to script in Perl, shell, C or C++ is desirable.
