Job summary

Amazon.com Services LLC in Bellevue, WA is seeking a Software Development Engineer to design, build, and operate the core distributed systems that power Model Factory. You will own end-to-end components—from design through deployment and on-call support—working closely with ML scientists and platform teams.

You will contribute to orchestrations, SDKs, and scaffolding that enable scalable training, evaluation, and deployment at scale, with emphasis on reliability, performance, and customer impact.

Qualifications

• 3+ years of non-internship professional software development experience.
• 2+ years of design or architecture experience for distributed systems.
• 1+ years of software development engineer or related experience.
• 1+ years of designing and developing large-scale distributed software using C#, C++, Java, or Perl.

Responsibilities

• Design, build, test, and operate services that orchestrate foundation-model data prep, training, evaluation, and deployment as contract-validated workflows.
• Own delivery of components end-to-end from design to deployment and on-call operations.
• Build/extend compute-backend integrations and job launchers across SageMaker, EMR, AWS Batch, Kubernetes/EKS.
• Improve resiliency and operability for long-running distributed jobs (checkpoint/resume, fault detection, retries, observability).
• Contribute to SDK, workflow orchestration, and schema/contract layer; help deploy with CDK infrastructure.
• Integrate containerized training/evaluation frameworks (e.g., PyTorch/FSDP, verl, NeMo/Megatron).
• Contribute to design discussions, write technical designs, uphold best practices (code reviews, testing, ops).
• Collaborate with ML scientists to translate training requirements into reliable, self-service platform capabilities; mentor interns/new engineers.

Job description

Description
At AWS SageMaker AI, we're making it easy to build state-of-the-art foundation models on the cloud. Model Factory is our platform for building, training, customizing, and evaluating foundation models at scale. Instead of hand‑chaining data prep, distributed training, evaluation, and deployment across thousands of GPU and AWS Trainium devices, Model Factory lets teams express the whole lifecycle as a single, contract‑validated workflow — orchestrated, reproducible, and fully managed. As LLMs and Generative AI scale, Model Factory is the platform that turns frontier training research into a reliable, repeatable pipeline for our internal teams and customers.Description
At AWS SageMaker AI, we're making it easy to build state-of-the‑art foundation models on the cloud.

Instead of hand‑chaining data prep, distributed training, evaluation, and deployment across thousands of GPU and AWS Trainium devices, Model Factory lets teams express the whole lifecycle as a single, contract‑validated workflow — orchestrated, reproducible, and fully managed. As LLMs and Generative AI scale, Model Factory is the platform that turns frontier training research into a reliable, repeatable pipeline for our internal teams and customers.
We're looking for a Software Development Engineer to help design, build, and operate the distributed systems at the core of this platform — the orchestration engine, compute integrations, SDK and contract layer, and the infrastructure that runs large‑scale training and customization jobs. You'll own components end‑to‑end, from design through delivery and on‑call operations, and work closely with the ML scientists and platform teams who depend on Model Factory every day. You'll turn requirements into robust, scalable, supportable services that fit cleanly into the overall architecture, uphold a high engineering bar, and grow your scope and technical leadership as you go.
A successful candidate has a strong software‑engineering foundation, writes high‑quality distributed‑systems and services code, communicates clearly, and is motivated to deliver results in a fast‑paced, ambiguous environment.
Key job responsibilities
As a Software Development Engineer on the SageMaker AI team, you will:

• Design, build, test, and operate services that orchestrate foundation‑model data preparation, training, evaluation, and deployment as reliable, contract‑validated workflows.
• Own delivery of individual components end‑to‑end — from design and implementation through deployment, monitoring, and on‑call operations.
• Build and extend compute‑backend integrations and job launchers — submitting, monitoring, and recovering large‑scale training jobs across SageMaker (Training/Processing/HyperPod), EMR, AWS Batch, and Kubernetes/EKS.
• Improve the platform's resiliency and operability for long‑running distributed jobs — checkpoint/resume, fault detection and recovery, retries, and observability (metrics, logging, experiment tracking).
• Contribute to the SDK, workflow orchestration, and schema/contract layer that teams use to declare and run jobs, and to the CDK infrastructure that deploys the platform.
• Integrate containerized training and evaluation frameworks (e.g., PyTorch/FSDP, verl, NeMo/Megatron) into the platform's task and recipe model.
• Contribute to design and architecture discussions, write clear technical designs, and uphold engineering best practices (code review, testing, operational readiness).
• Collaborate with ML scientists and internal customers to translate training requirements into reliable, self‑service platform capabilities, and help onboard and mentor interns and new engineers as you grow.

Basic Qualifications

• 3+ years of non‑internship professional software development experience
• 2+ years of non‑internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 1+ years of software development engineer or related occupational experience
• 1+ years of designing and developing large‑scale, multi‑tiered, multi‑threaded, embedded or distributed software applications, tools, systems, and services using: C#, C++, Java, or Perl experience
• 1+ years of Object Oriented Design experience
• Bachelor's degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related field
• Experience programming with at least one software programming language

Preferred Qualifications

• 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Bachelor's degree in computer science or equivalent
• - Experience with workflow/pipeline orchestration (Airflow, Step Functions, or similar) and event‑driven or service‑oriented architectures.
• - Experience with container and cluster compute (Kubernetes/EKS, Ray, Slurm, AWS Batch) and cloud infrastructure‑as‑code (AWS CDK/CloudFormation).
• - Experience building and operating fully‑managed cloud services at scale, including resiliency, checkpointing, and fault tolerance for long‑running jobs.
• - Familiarity with machine‑learning / deep‑learning training workflows, GPU/accelerator compute (SageMaker HyperPod, AWS Trainium, P5‑class GPUs), or distributed‑training frameworks (PyTorch FSDP, Megatron‑LM, DeepSpeed, verl).
