About the Company

Autoscience Institute is building AI systems that autonomously conduct AI research.

The company is developing autonomous research agents capable of discovering evaluating and improving AI systems with minimal human intervention. Autoscience has already demonstrated autonomous AI research capabilities including an AI agent that autonomously created peer-reviewed literature at the ICLR 2025 Workshops.

The companys commercial product Mira is an autonomous research agent already deployed at top-three global quantitative trading firms and has delivered 20% model performance improvements.

Backed by General Catalyst Perplexity Fund S32 MaC Ventures and Toyota Ventures Autoscience has raised $14M and is currently progressing toward a Series A. The company operates with a tiny highly technical team of approximately 10 people.

As a Senior / Staff Software Engineer youll join one of the companys earliest senior engineering hires and work directly on the systems powering autonomous AI research.

This is a high-leverage individual contributor opportunity where youll write production Python build recursive self-improvement systems improve agentic discovery infrastructure and translate research ideas into reliable production software.

The team operates with exceptional autonomy and iteration speed. Engineers are expected to own complex projects end-to-end make architectural decisions independently and operate without significant handholding.
