Senior Software Development Engineer - Quantum Runtime Systems, Amazon Braket

Amazon Braket is evolving to support fault-tolerant quantum computing. We need a Senior SDE who can build high-performance systems infrastructure for quantum workloads - the kind of engineer who thinks about latency budgets, resource lifecycle, and how to make hardware accessible through clean software abstractions. If you have a background in device drivers, OS kernels, embedded systems, or low-latency distributed infrastructure, and you want to apply that expertise to a fundamentally new kind of computing device, this role is for you. Key job responsibilities - Design and implement interfaces that connect Braket's infrastructure to quantum hardware with minimal overhead - Build session management, memory management, and execution control systems for quantum device interactions - Optimize the critical path between customer workloads and quantum processors for minimal latency and maximum throughput - Collaborate with the existing Workload Execution team on shared runtime infrastructure (brokers, scheduling, resource management) - Work within Braket's established code review and operational readiness processes when contributing to shared production systems - Work with quantum hardware providers to define and evolve integration specifications - Contribute to the architectural evolution of Braket's execution stack for fault-tolerant workloads
