Senior Software Engineer

Description

We are looking for a Senior Software Engineer to help build NeMo Platform, the company’s product for developing, evaluating, deploying, and operating AI systems at scale. This role will focus on NeMo Evaluator, which helps teams understand whether changes to AI agents are making those agents better. As AI systems become more autonomous and more deeply integrated into real workflows, teams need practical infrastructure for observing behavior, measuring progress, catching regressions, and iterating with confidence.

Our roadmap is increasingly focused on agentic development and automated agent improvement: giving teams the infrastructure they need to compare versions, understand behavior, and make empirically grounded improvements over time.

What you'll be doing:

Design and implement Python-first APIs, SDK workflows, and plugin interfaces for building, measuring, and improving agents across multiple runtimes and product surfaces

Build reusable systems for observing behavior, measuring progress, detecting regressions, and turning runtime evidence into product decisions

Build systems for ingesting, normalizing, validating, and analyzing agent execution data and evaluation datasets

Partner with research, product, platform, and infrastructure teams to integrate agentic capabilities broadly across the company agent runtimes and developer workflows

Help turn emerging agent development and improvement techniques into reliable, reusable product capabilities

Improve reliability, observability, debuggability, and performance across NeMo Platform, SDKs, plugins, jobs, and developer workflows

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

Drive “speed of light” engineering: fast iteration, high ownership, pragmatic decisions, and performance-minded implementation under production constraints

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

What we need to see:

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

5+ years of professional software engineering experience building production systems

Excellent Python engineering skills, including API design, typing, testing, debugging, performance analysis, and maintainable software design

Experience designing SDKs, libraries, plugins, CLIs, or other developer-facing interfaces

Experience with distributed systems, cloud-native services, containers, Kubernetes, or job orchestration

Strong understanding of reliability, scalability, security, and performance tradeoffs in production infrastructure

Experience with structured data modeling and validation systems such as Pydantic, typed schemas, event/trace models, or SDK-generated types

Ability to work independently, define technical scope, break down ambiguous problems, and drive work across team boundaries

Clear communication skills and a track record of collaborating with engineering, product, research, or customer-facing teams

Ways to stand out from the crowd:

Experience building, deploying, and iterating on production agentic AI systems where evaluation was used to measure and improve real product outcomes

Experience designing evaluation workflows for heterogeneous agents, including tool-using agents, RAG agents, workflow agents, coding agents, or long-running autonomous systems

Experience integrating evaluation capabilities across multiple products, runtimes, or internal platforms, especially through Python SDKs, plugins, or shared developer tooling

Strong ability to connect technical evaluation work to business outcomes, product quality, user experience, reliability, or operational efficiency

Experience with enterprise AI systems where measurement, regression testing, observability, governance, and continuous improvement are required for production deployment
