We are looking for a Harness/Platform Engineer to build that foundation. You will play a critical role in making the program's work possible, repeatable, and trustworthy. When a researcher runs an experiment, your platform decides whether the result can be reproduced tomorrow. Our current direction builds on NVIDIA NeMo agent tooling, and you will help shape where it goes. You will keep the whole loop visible, from environment to run to result. You will work closely with security research and evaluation engineers, learning their workflows and smoothing their paths. Good platform work here looks like fewer surprises: environments that behave, tooling that stays versioned, and runs that repeat. When something breaks, you will debug it with the people who felt it first. You will treat researcher time as precious and remove friction wherever you find it.
What You'll Be Doing:- Harness development: Design, implement, and maintain the agent harness.
- Evaluation infrastructure: Build the systems we use to run and reproduce experiments.
- Reproducibility: Own environments, tooling, and repeatable runs.
- Collaboration: Partner with security and evaluation engineers on their workflows.
What We Need To See:- Bachelor's degree (or equivalent experience) with 5+ years of software engineering experience.
- Technical core: Strong Python engineering plus comfort with containerized environments and CI/CD.
- Infrastructure familiarity: Experience with agent frameworks, LLM orchestration, ML infrastructure, or evaluation harnesses.
- Reproducibility instincts: Care for versioned tooling and repeatable results.
Ways to Stand Out from the Crowd:- NeMo experience: Hands-on work with NVIDIA NeMo or similar agent frameworks.
- Security context: Exposure to security tooling or vulnerability research.
- Developer experience: Building internal tools other engineers enjoy using.
Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 152,000 USD - 241,500 USD.
You will also be eligible for equity and benefits.
Applications for this job will be accepted at least until July 30, 2026.
