AI Engineer

About Fractional AI

Fractional AI builds bespoke gen AI software to transform businesses.

Every C-suite in the country is trying to bridge the gap between AI in theory and AI in practice. We close this gap with exceptional engineering talent and custom end-to-end AI builds.

By joining Fractional AI, you're stepping onto a San Francisco, NYC, and Dubai-based team working on gen AI projects for top companies from the comfort of an engineering-first startup.

About the Role

Joining Fractional AI as an AI Engineer, you'll play a leading role in building and shipping AI applications for our customers - from understanding customer needs to deploying solutions in their environments - all while shaping our engineering and broader Fractional culture for the next 100+ engineers.

By the time you've completed your second project, you'll have shipped LLM applications across more companies and use cases than the vast majority of AI engineers in the world.

What You Bring to the Table

• You write exceptional code + deeply care about the craft of coding (4+ years of experience): you build elegant, production-ready code; you have strong proficiency across multiple programming languages
• You have a track record building with Large Language Models: you have experience building scalable applications with LLMs, using frameworks such as LangChain, LlamaIndex, etc.
• You love solving hard, new problems: you are comfortable self-teaching, asking "why?," and experimenting to solve problems you haven't seen before
• You are 'start-up ready': you jump in without instruction
• You are comfortable talking with customers: you deeply care about the customer
• You are a great teammate

What You'll Do

• Design and develop custom AI solutions tailored to the unique needs of our customers, ensuring seamless integration and scalability
• Partner with a high-caliber team across the full project lifecycle, from requirements gathering, to prototyping, system design, coding, testing, deployment, and support
• Actively shape our engineering and broader company culture

Work Arrangement: 4 days in-person, Fridays remote (San Francisco, CA and New York, NY)

Our Tech Stack

• We're generally tech stack agnostic - we work in our customers' environments and code bases. A lot, but definitely not all, of our work is in python.
• After working at Fractional AI for a few years, you'll be an expert at using the various foundational models, building with tools like Langchain/Langsmith, and various other AI tooling. Also works with LlamaIndex, OpenPipe, Pinecone, and ChromaDB.
