About NewtonX

NewtonX delivers AI-powered B2B insights to the world's most demanding clients-McKinsey, Blackstone, Microsoft, Google, KKR-who use our data to make high-stakes decisions. Our research has been cited by Fortune, Forbes, TechCrunch, Adweek and more. We've builta reputation as the quality standard in the industry. Now we're building AI systems to make that quality infinitely scalable.

NewtonX has raised $47M in funding from VCs like Two Sigma Ventures, Third Prime, XFund and Citi Ventures.
The Role

In this role, you'll own the core LLM infrastructure powering two products redefining B2B research:

Hub - The central cockpit for B2B research. Build self-serve features that compress weeks into days: question → expert insight → follow-up, powered by RAG and adaptive workflows.

Prime - Syndicated intelligence at scale. Architect automated systems that continuously capture expert opinions-creating longitudinal datasets and refreshable dashboards that compound in value.

The technical challenge: fusing structured survey data with unstructured expert knowledge, building semantic search across proprietary corpora, and creating AI pipelines that maintain research-grade quality at scale. If you love building novel data systems that turn raw signals into defensible, high-margin products, this is where you'll do the most important work of your career.
What We're Looking For
Required

• You write exceptional code, fast. 3-4 years of experience shipping production code in a fast-paced environment
• Full-stack expertise: Moderate proficiency in React, TypeScript, and modern frontend frameworks. Backend experience with Python, Node.js, or similar
• AI/ML implementation experience: Hands-on experience integrating LLMs, building with OpenAI/Anthropic APIs, or implementing ML models in production. We care more about a demonstrated eagerness to learn and an understanding of complex systems than specific years.
• Cloud and infrastructure: Experience with AWS, Docker, and modern deployment practices
• Quality mindset: Experience with testing, code reviews, and maintaining high code quality standards
• Customer focus: Ability to translate user needs into technical solutions while maintaining engineering best practices

Nice to Have

• RAG systems, embeddings, semantic search
• Real-time data processing or streaming architectures
• Open-source contributions in AI/ML

What actually matters
We care less about credentials and more about demonstrated ability. If you've built something interesting with LLMs- a side project, an open-source contribution, a blog post that shows how you think- put that at the top of your application.
