Software Development Engineer, Hydro

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 novel 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.

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 novel 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.
