Job description

Factor is building a growth platform where acquisition, creative, and software run as one system. You build it end to end, from the interfaces operators use every day to the services, databases, and algorithms underneath. Machine learning is becoming a larger part of how the platform decides what to run, so experience with models is a real plus.

In this role, you will

• Design, build, and ship features across the frontend and backend.
• Model data and own the databases and pipelines the platform runs on.
• Write the algorithms behind targeting, testing, and optimization.
• Build and deploy models, from regression to fine-tuned LLMs, where they beat simple rules.
• Own your systems in production: performance, reliability, and monitoring.

You might thrive in this role if you have

• Strong engineering fundamentals: data structures, algorithms, and system design.
• Production experience across the stack, such as TypeScript, React, Node.js, and Python.
• Solid database skills: schema design, SQL, and query performance.
• A track record of shipping software that is live and in use.
• Daily use of AI coding tools, with judgment about their output.

Nice to have

• Machine learning experience, such as training regression and classification models.
• Experience fine-tuning or evaluating language models.
• Background in ad tech, marketing technology, or experimentation platforms.

About Factor

Factor is an AI-native growth studio. We hire people who want to own a system that acquires and converts, and prove it in production. The team is small and remote-first, and the work is judged on live results.
