AI Engineer

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 (see some of our case studies to learn more).

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:

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 tools and frameworks (e.g., OpenPipe, Pinecone, ChromaDB).

A day in the life:

You have a weekly standup with the customer (the CTO at the client) to chat through tradeoffs, progress, and timeline. • You join team lunch (which doubles as the Fractional AI cross-project standup) to hear about different projects we’re working on … the lunch will turn into a lively debate about Weights and Biases v.

Braintrust capabilities. • You’ll have some solo heads down time to continuing jamming on the high priority pieces for that print.

Who you'll work with:

Why you should (and shouldn’t) join us We’re big believers in transparency and know joining a company is a big decision.

We’re not the best fit for everyone and try to be clear on what we are and what we’re not so you make the choice that’s right for you.

Why join Fractional? • Build on the forefront of applied AI: You’ll have a front row seat to how the world’s leading companies are actually deploying AI solutions.

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. • Solve big, real problems: Companies come to us when they can’t solve some of their biggest problems themselves.

For you, that means learning everyday, never getting bored, and working across a range of industries, customers, and products. • Learn with and from the best in person: We're a team of senior engineers (some former founders, some former engineering leaders) who only want to work on high-impact projects.

Working elbow to elbow in our San Francisco, NYC, or Dubai offices means things like team lunches, quick brainstorming, and the right amount of banter.

Why shouldn't you join Fractional? • Preference for just speed or quality: We love hacking things together for a proof of concept but ultimately our code will be put into production in our customers’ environments - you need to enjoy balancing elegance and expediency.

You’ll frequently interact with engineers from the customer’s team to ask questions and problem solve.

A deep understanding and appreciation of the customer is crucial.

Our Values Overdeliver.

Overuse AI.

Over "engineer" the culture.
