Research Engineer

About us

Our first product, Sculptor, gives engineers the power to run and coordinate multiple coding agents in parallel, helping them move faster, and stay in flow. At its core, Sculptor is about giving developers more power to make software creation faster, safer, and more reliable.

More broadly, our mission is to make "open" AI agents win over closed agents. To do that, we’re starting with coding agents, since they both make it easier to construct future agents, and we can use them ourselves. The insights we gain from these agents will help us improve both the capabilities of the underlying models and the interaction design for agents. Ultimately, we aim to rekindle the dream of the *personal* computer, where computers become truly intelligent tools that empower us, giving us freedom, dignity, and agency to pursue the things we love.

Summary

In this role, you’ll build the AI systems that power Sculptor and ensure that coding agents work “for you”. You’ll directly shape the intelligence behind the product you use every day, and will have real influence on the problems we tackle and the approaches we take. We're looking for scientists who combine research excellence with pragmatic engineering; someone who can push the boundaries of what's possible while shipping real solutions that delight our users.

What you'll do

• Build verification systems that make coding agents more reliable, including test generation and LLM-as-judge approaches

• Turn ambiguous problems into quantifiable ones, through a mixture of annotation, synthetic data generation, and product logging

• Create agent improvement loops via self critique and evolutionary algorithms

• Build experiences and tooling that help developers easily audit and manage coding agents

• Partner with the product team to translate cutting-edge applied research into features users actually want

You are

• Driven by making AI agents that actually work in the real world

• Excited to see your research ship to thousands of developers

• Independent and self-motivated

• Comfortable with Python, LLMs, and agentic approaches

Compensation and Benefits

• Support for self-improvement: coaching, courses, conferences, etc

• Company offsites—past locations include NYC, Santa Cruz, Hawai’i, and Tokyo!

• Company paid medical, dental, and vision for you and your dependents

• Lunch provided daily for onsite employees

• $250 lifestyle stipend per month

• Flexible PTO

• Frequent team events, dinners, and fun activities

• Compensation packages are highly variable based on a variety of factors. If your salary requirements fall outside of the stated range, we still encourage you to apply. The salary range for this role is $170,000–$400,000.

How to apply

All submissions are reviewed by a person, so we encourage you to include notes on why you're interested in working with us. If you have any other work that you can showcase (open source code, side projects, etc.), certainly include it! We know that talent comes from many backgrounds, and we aim to build a team with diverse skillsets that spike strongly in different areas.

We try to reply either way within a week or two at most (usually much sooner).
