The NeoSigma Research Fellowship is a 10-14 week, in-person, paid program for exceptional researchers and builders to work on open, real-world AI challenges.

Fellows collaborate closely with our research team on problems at the frontier of self-improving AI systems. Projects are intentionally open-ended—we work with each fellow to define a direction that aligns with their strengths, interests, and long-term goals.

We strongly encourage fellows to contribute to the broader research community—through publications, technical blogs, and open research artifacts—helping share learnings and advance the field.

What you'll do:

• Work on open-ended problems in self-improving AI: agentic systems, auto-evals, verifier research, and benchmarks
• Be embedded in the core research team from day one
• Define your own research direction based on your strengths and interests
• Run experiments, iterate fast, and push ideas from hypothesis to working system
• Publish findings: papers, technical blogs, and open research artifacts
• Collaborate daily with the research team through mentorship and brainstorming sessions

What we look for:

• Currently pursuing or holding a Master's or PhD degree in Computer Science, Machine Learning, or a related field
• Hands-on experience building LLM-powered or agentic systems in production
• Strong research taste in evals, post-training, or agent architecture
• Own problems end-to-end, from first idea to shipped artifact
• Comfortable working directly with a small, fast-moving team
• High attention to detail across research rigor, code quality, and writing

Our Core Values:

• Customer Obsession - We start with the customer and work backwards. We aim to earn trust through consistent delivery, thoughtful listening, and by obsessing over customers.
• Intellectual Honesty - We operate with high trust and low ego. Ideas matter more than titles, and we communicate openly and directly while assuming good intent, even in strong disagreement.
• Bias for Action - We set high standards and move quickly to meet them. We prefer building and learning with customers over debating in the abstract, and we iterate based on real feedback.
• Extreme Ownership - We take responsibility for outcomes, not just tasks. Ownership means seeing problems through to completion and ensuring solutions truly work in practice.

Benefits and perks

• Competitive salary plus meaningful equity package
• Comprehensive medical benefits and generous PTO
• Flexible work arrangements
• Direct impact on company direction and technical decisions
• High ownership and the opportunity to make a career-defining impact
• Visa sponsorship

About Us

NeoSigma is a product-driven research lab building the intelligence layer that helps close the feedback loop between your customers, products, and AI systems.

We are a small, intensely technical team of researchers and engineers who have trained frontier-scale models and widely used AI products and agents at MIT, Parallel Web, Essential AI, Apple, and Amazon.
