Original job description

Our client is a nine-person AI infrastructure startup building the systems that make autonomous agents reliable in production. Founded in 2024, the company turns agent failures, traces, evaluations, and human feedback into replayable learning environments with regression control inside the optimization loop. It has raised $6.9M and already supports large enterprise customers across financial services, healthcare, and technology.

We are hiring an AI Research Scientist to advance the frontier of reliable agentic AI. You will be a core contributor to original methods for agent simulation, evaluation, optimization, and continuous learning, while remaining hands-on enough to turn research ideas into working systems and production-facing capabilities. Research depth is the priority, with real product impact and close collaboration across a small technical team.

What you'll do

Develop new methods, algorithms, and systems across the lifecycle of reliable AI agents

Create novel approaches for simulation, evaluation, optimization, and regression control in real-world agent settings

Study agent failures, traces, and human feedback to design more reliable learning loops

Turn research ideas into experiments, prototypes, and production-facing capabilities

Partner with product and engineering teams to translate frontier AI work into customer value

Help define the company's technical direction in agent reliability, evaluation, and optimization

Contribute independent ideas and challenge assumptions with rigorous experimental evidence

A PhD in computer science, machine learning, or a closely related field, or equivalent research depth

At least one year of research experience focused on LLM agents or agentic systems

Expertise in evaluations, novel applications of AI agents, or agent frameworks

Strong publication evidence at venues such as NeurIPS, ICLR, ICML, or ACL, or meaningful contributions to widely used open-source projects

Proficiency in Python and the ability to implement research ideas hands-on

Independent research judgment and the ability to clearly explain your personal contributions

Availability to work East Coast hours from the United States or Canada

Bonus points

Experience as a first research hire or member of a small startup research team

Research experience at an AI lab or applied AI company

Experience translating AI research into production systems and enterprise products

Familiarity with reinforcement learning, continuous learning, simulation systems, or agent optimization

A fresh PhD is welcome if the research fit and hands-on ability are strong

Base salary of $130K-$200K

Approximately 1% equity

Direct collaboration with recognized researchers and repeat founders

Visa transfers, STEM OPT, H-1B transfer, or TN support may be available

Fully remote within the United States or Canada

Work on East Coast hours

Full-time position on a small, research-intensive team
