Senior Software Development Engineer, EBS Placement

Key job responsibilities

• 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 launch — and own operational excellence for the systems you build
• Identify and drive cross-team technical initiatives that improve placement capabilities and strengthen EBS platform architecture
• Collaborate with and influence engineers across EBS, EC2, and partner AWS teams to deliver cross-service integrations and platform improvements
• Lead design reviews, raise the engineering bar through code reviews, and establish technical best practices for the team
• Mentor engineers across levels and contribute to a team culture of technical excellence and operational rigor
