Full Stack AI Engineer (Founding)

About SellScale

SellScale is an Agentic AI company. In 10 years, we believe the most efficient orgs will rely on a collaborative, agentic AI to grow their businesses.

Right now, we are in a massive AI gold rush. The agents we’re building leverage PhD-level thinking paired with state-of-the-art GTM tools (prospecting, web intent, sequencing, etc) - to fundamentally change how companies approach their growth.

Role

We’re growing - and we’re expanding the eng firepower here. We are looking for a Founding Full Stack AI Engineer. Extensive previous AI experience is not required - but it is a bonus. Interest in AI, solid CS fundamentals, and full-stack capabilities are a must.

You are a good fit if…

1. You attend hackathons and love building.
2. You want to play with all the new releases - from OpenAI O3 to Agentic Infrastructure.
3. You build apps in your free time - Product Hunt launches to playing with the newest LLM release.
4. You are ready to go all-in on an Agentic AI startup and be an owner, in the heart of SF, as part of a founding team.

Reasons to not apply…

1. You are looking for “senior leadership” guidance - the buck stops at you to solve problems!
2. You don't enjoy in-office culture - we work 5 days a week.
3. You’re looking for larger companies - this is a founding team!

Positives

1. You will make decisions that will take you 10 years at Google to do.
2. There are few other places where you will learn more about building in an agentic / AI than here.
3. You will have a driver’s seat in building a unique product with a growing customer base.

Application process

1. Intro call - get to know Selix & the SellScale team.
2. Technical - Build a full stack app, then pair-program on it live.
3. Product & pace - Walk through the non-tech side of SellScale - filled with prototyping, WOZing, prompting, and more.
