Senior Software Engineer, NeMo Helix Core Platform

About the role

We are looking for a Senior Software Engineer to help build NeMo Helix, NVIDIA’s product for developing, evaluating, deploying, and operating AI systems at scale. This role is for a senior engineer/architect for our Core team which owns and ships an open source plugin-based AI platform for running and optimizing Agents targeting multiple compute backends (local/docker, Kubernetes, Slurm, etc.).

As AI systems become more autonomous and more deeply integrated into real workflows, teams need robust APIs and orchestration systems for running, monitoring, and optimizing Agents at scale. Increasingly, the users of these systems are themselves autonomous or semi-autonomous Agents. The NeMo Helix group is building a sophisticated agent execution framework to enable agents to automatically run hundreds of experiments in parallel to find the most efficient agent architectures for our customers. This is important product engineering research for making agents more sustainable. AI systems are not yet nearly as efficient as they can be, and systems like NeMo Helix will allow large scale AI consumers to automatically tune their agents to use fewer tokens and rely on more efficient models with better throughput.

What you'll be doing:

- Working in a product research environment where we place big bets on where the future is heading, adapting in real time as we build alongside an industry that is constantly evolving with us. This means fast iteration, high ownership, pragmatic decisions, and performance-minded implementation under production constraints

- Designing an Agentic Execution system that are flexible enough to work in many environments (local, k8s, Slurm, on prem / air-gapped)

- Provide senior technical leadership through design reviews, code reviews, mentoring, and ownership of ambiguous cross-component problems

- Building and maintain our Core Platform APIs for running jobs, storing data, entities, secrets, and RBAC and Auth

- Extending our flexible Plugin Architecture that makes it easy for many teams and external customers to install new capabilities into our system

- Building in the open in our OSS repo, keeping up the high standards that the open source community demands

- Shipping code at the speed of light with an unlimited token budget using best in class agentic coding tools

- Improving reliability, observability, debuggability, and performance across NeMo Helix, SDKs, plugins, jobs, and developer workflows

- Building strong test coverage across unit, integration, E2E, Docker, and Kubernetes workflows

What we need to see:

- BS, MS, or equivalent experience in Computer Science, Computer Engineering, or a related technical field

- 10+ years of professional software engineering experience building production systems

- Comfort working in a very fast and ambiguous environment

- Exceptional communication, both verbal and written. This includes the ability to produce and review high quality architectural RFCs, and to discuss them clearly with the right level of technical detail for the right people (Engineer, Product, Marketing, etc.)
