SeniorSoftwareDevelopmentEngineer,EBS

If solving complex distributed systems problems at massive scale excites you, EBS Placement is the place to do it. Our team builds and operates the systems that decide where every EBS volume lives across AWS's storage fleet — infrastructure that serves exabytes of data and trillions of I/Os every day. Every EBS customer, from startups to the world's largest enterprises, depends on the decisions our systems make. We're looking for a Senior Software Development Engineer to drive the technical direction of placement systems — from real-time decision engines that place customer volumes in milliseconds to background fleet optimizers that continuously rebalance heat and respond to shifting fleet topology and customer workload patterns. You'll lead the design of solutions to complex problems involving multi-dimensional optimization — balancing performance, availability, durability, density, and cost — at a scale and complexity few systems operate at. Placement sits in the critical path for EBS. We shape how EBS evolves to support new volume types, new server capabilities, and new customer workload patterns. We regularly partner with principal engineers, scientists, and teams across EC2 and EBS to deliver integrations that make the broader AWS fleet more efficient. If you want your technical leadership to have real impact at AWS scale, and you're excited by multi-year investments in systems that power one of AWS's largest businesses, we'd love to talk to you. Key job responsibilities As a Senior SDE on the EBS Placement team, you will: - Drive technical design and architecture for placement systems that make real-time decisions at AWS scale, balancing performance, availability, durability, density, and cost - Translate ambiguous requirements — new volume types, new storage hardware, shifting workload patterns — into durable, extensible solutions that keep placement fast as the fleet grows - Lead features end-to-end — from design through implementation, deployment, and launc
