Rust Library Jobs in Seattle, WA (NOW HIRING)

Are you a systems builder who loves solving complex distributed systems challenges. Do you want to revolutionize how the world's largest cloud infrastructure is managed. Are you passionate about building developer-friendly APIs and infrastructure that empowers thousands of engineers.

Join us and help design the future of network infrastructure management!
Our team is part of AWS Networking Services and owns the administrative and management capabilities for Amazon's global network infrastructure. We're building next-generation management APIs and infrastructure that replace legacy protocols with modern, secure alternatives across AWS's massive device fleet. Our mission is simple but ambitious: enable engineering teams to build scalable, secure, and reliable network management solutions that serve as the foundation for all AWS networking services.
Your focus will be on developing state of the art device management infrastructure

You'll work on SDK development in Rust, Python, and Java; build secure inter-process communication systems; implement certificate management and device identity frameworks; and create the observability infrastructure that gives network engineers visibility into Amazon's global network fleet. This isn't just API development - it's building the critical infrastructure that keeps AWS running at unprecedented scale.
AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we're the people who keep the cloud running

We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain - and we're looking for talented people who want to help.
You'll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You'll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers

And you'll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.
Key job responsibilities
You will architect and implement highly scalable, distributed systems that manage network infrastructure across AWS's global footprint. You'll solve complex and ambiguous problems efficiently and with high quality. You'll play a pivotal role in shaping the definition, vision, design, roadmap, development, and operationalization of customer-facing services

You'll be given an outcome and the freedom to set the direction based on data-driven decisions.
This role requires deep technical expertise in distributed systems, strong collaboration skills, and a customer-obsessed mindset. Our most important customers are our own developers - you'll work directly with component teams, infrastructure engineers, and network operators to deliver solutions that improve developer experience while maintaining the highest standards of security and reliability. You'll contribute to critical and highly-visible infrastructure within the AWS business

Key responsibilities include:
* Design and implement core management API infrastructure including on-device gateways, SDK libraries in Rust/Python/Java, secure IPC mechanisms, and device connectivity frameworks
* Build model-driven APIs that enable seamless integration for component teams, with automatic forward and backward compatibility
* Develop asynchronous execution infrastructure supporting long-running operations, callbacks, streaming, and pub/sub mechanisms for rich programmability
* Create certificate management and device identity systems supporting secure authentication across all AWS regions and partitions
* Implement observability infrastructure including on-device agents for structured logging, distributed tracing, and metrics collection
* Partner with security teams to implement robust authentication, authorization, encryption, and auditing for device access
* Optimize system performance to support high-volume operations at AWS scale
* Drive architectural decisions that will scale systems from experimental to production-ready infrastructure serving the global fleet
* Write high-quality, well-tested code and participate in code reviews to maintain engineering excellence
* Mentor junior engineers and contribute to technical design reviews across the team
A day in the life
You must ensure our solutions meet the needs of our most important customers - our own developers. You will be a hands-on technical contributor working on problems that directly impact AWS' ability to scale and serve millions of customers globally. You'll design APIs and SDKs that thousands of engineers will use daily, making complex infrastructure management operations simple, safe, and reliable.
Your technical decisions will influence how Amazon manages network infrastructure for years to come

You'll work on replacing legacy systems with modern, secure alternatives while ensuring backward compatibility and seamless migration paths. You'll tackle challenges spanning the full stack: from embedded systems and kernel interfaces to RESTful APIs, RPC services, and modern web applications. You'll use your strong technical and communication skills to gather requirements, generate designs, and carry projects through all software lifecycle stages.
You'll have access to senior leadership and engineering staff

You'll find this role technically challenging and engaging, full of opportunities to learn and grow, with large impact on AWS and the cloud computing industry.
About the team
We're a focused team working on transformational infrastructure that will fundamentally change how network infrastructure is managed at Amazon. We serve many internal customers and play a critical role with multiplying effect across AWS Networking.
We work with Rust for performance-critical systems, Go and Python for services and tooling, modern RPC frameworks for secure communication, and contemporary web frameworks for user interfaces. We run very lean and scale with the business, without repeated technical or operational burden

We use builder tools principles: we make the right things common, common things easy, and ensure uncommon things are possible. Our systems span from embedded device interfaces and kernel integration to cloud-scale distributed services and developer-facing APIs.
We pride ourselves on building developer-friendly infrastructure that makes complex operations simple and safe. The team operates with high autonomy, direct customer engagement, and significant impact on AWS networking future

We're breaking free from legacy constraints and building independent infrastructure that will enable rapid innovation. Our roadmap includes revolutionary approaches to infrastructure management: on-device gateways, asynchronous APIs, SDK development across multiple languages, and comprehensive observability platforms. You'll join us at an inflection point where your contributions will directly shape the next generation of infrastructure management at AWS.
