Senior Research Engineer — Large-Agent Scaling

United States Digital Space LLC; San Francisco (CA); Hybrid; USD 500,000 - 850,000; Full time

Job summary

United States Digital Space LLC is seeking a generalist researcher-engineer to design and run large experiments on agent teams and to build scalable systems the teams rely on. You'll work at the research-engineering boundary, turning vague questions into runnable experiments, and collaborating with researchers to uncover what the data reveals about performance, efficiency, and scale.

You'll lead end-to-end experiments, develop experimental infrastructure, and communicate findings clearly to

Qualifications

• Significant software engineering, ML or research engineering experience.
• Ownership of substantial end-to-end projects (large system, evaluation, benchmark, agent product, or research project).
• Genuine enjoyment of both research and engineering work.
• Ability to think quantitatively about complex systems and question numbers.
• Capacity to work from vague questions rather than a strict spec.
• Results-oriented mindset with flexibility and impact.
• Clear written and verbal communication.
• Concern for societal impacts of your work.

Responsibilities

• Design, run and interpret large-scale experiments on agent teams, reasoning rigorously about what the data does and doesn't show.
• Investigate how performance and efficiency change as team size, compute and task horizon grow, and find the bottlenecks that limit them.
• Build and scale the systems that run very large agent teams reliably, and debug the failures that only appear at scale.
• Design evaluations for long-horizon problems, and keep their results trustworthy.
• Build the tooling and metrics that let researchers see what a large agent team is doing and why.
• Partner with research teams across the company so they can run their own experiments on the platform, and communicate findings clearly
