About The Position

Want to help advance the state of the art in open source distributed
programming, AI agents and scalable systems? We’re looking for engineers to join
the leaders of the open source Hydro framework for Rust, solving novel problems
at the intersection of distributed systems and AI. Much like Rust originally
guaranteed memory safety, Hydro provides distributed safety: compile-time checks
that prevent a wide class of distributed bugs. The Hydro team is working with
cutting-edge compiler, AI and distributed systems technologies—including deep
integrations with the Rust type system, formal verification techniques, agentic
code generation and distributed system optimizations. As a member of this team,
you will work on developing novel features for Hydro driven by our customers, in
collaboration with the open source community and research partners. Challenges
remain in compiler design, distributed-aware AI agent design and distributed
systems engineering—all while meeting AWS's exacting standards for scale,
reliability, and security.

Your impact will be immediate and visible in both open source and coding agents.
You'll ship features that directly improve how developers work. You can expect
to engage with AWS-internal customers from critical cloud services, and external
customers as well. From day one, you'll have opportunities to lead—whether
that's owning projects, defining technical direction, or shaping how the team
operates.

This is your chance to work with the next generation of technologies for
intelligent, cloud-scale software engineering.

Requirements

• 5+ years of non-internship professional software development experience
• 5+ years of programming with at least one software programming language experience
• Experience as a mentor, tech lead or leading an engineering team
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 3+ years working on concurrent, parallel or distributed systems OR 3+ years working on compilers (LLVM, GraalVM, etc.) or modern build tools (Nix, Bazel, etc.)

Nice To Haves

• 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Bachelor's degree in computer science or equivalent
• Fluency in Rust
• Experience building complex software systems that have been successfully delivered to customers
• ֵExperience leveraging AI based development tools to build production software

Responsibilities

• You'll work on the open source Hydro framework and its integration with Amazon's Kiro family of coding agents.
• Working directly with customers running some of the world's biggest distributed systems, you'll uncover real-world development challenges and translate them into product capabilities—staying true to Amazon's customer-obsessed approach.
• You'll build and deploy cutting-edge software engineering technology, advancing the safety, reliability and simplicity of building the cloud-scale software our customers demand.
• Your responsibilities span the full lifecycle: from compiler technologies to agent training and steering to scalable deployment.
• You'll balance innovation with operational excellence, making technical choices that enable Hydro open source and Kiro agents to work smoothly for a wide class of developers while meeting AWS's standards for scale and security.
