Software Development Manager, SageMaker Training

Interested in building the distributed systems that let customers customize foundation models at scale The SageMaker Training and Model Customization team builds the services customers use to fine-tune and post-train models against their own accuracy reliability and cost targets. We are looking for a Software Development Manager to lead the team that owns those capabilities.

Model customization is the fastest-moving layer of the machine learning stack. Post-training has gone from supervised fine-tuning to reinforcement learning against verifiable rewards and from single-turn tasks to agentic training where a model learns by acting in an environment over long trajectories. Each shift changes the shape of the workload: reinforcement learning puts an inference engine inside the training loop and agentic training adds environments and tool calls that move the bottleneck from run to run. Your team turns each new technique into a capability customers can use without rebuilding the platform every time the research moves. Underneath it stays a hard distributed systems problem across large accelerator fleets where a single node failure can halt progression.

As the manager you own the team and its charter. You will hire and grow engineers set technical direction with your senior engineers and product managers and decide what the team does and does not build. You own the roadmap and defend its tradeoffs with leadership. You own the service in production including on-call health operational metrics and the customer requests that come with a service in the critical path of customer training workloads.
