Role
"The idea that you now have a real virtual teammate, that you can assign work to, that you can make them do increasingly advanced things - and issue many requests in parallel - this is true task delegation."
Most agents today are for coding, but 99% of the world aren’t engineers. At SellScale, we’re building AI Agents for non‑technical people, starting with the sales org. Our initial version of Selix includes three agents:
Selix Worker
(to complete outbound campaigns),
Selix Supervisor
(to help manage the worker), and
Selix Secretary
(to update CRM, set meetings, and more).
As we grow, we’re looking for a
Full Stack Engineer who is back‑end leaning . This position will help lay the backend/infrastructure/integrations for scaling Selix. You’ll be hopping between classic SaaS integration problems, user‑facing requests, and AI agent infrastructure.
This position is targeting a minimum 1% equity minimum grant.
Requirements
2‑5 years work experience
– you’re familiar in a production capacity and have worked on infrastructure ready to scale.
Production experience in our tech stack
– able to ship across the stack, not just backend:
Front‑end: React/Typescript
Back‑end:
Python
(e.g., Flask, FastAPI, or Django)
Database: SQL experience (e.g., Postgres)
Early stage ready
– interest to join a startup as one of the first N employees as a founding engineer.
Why someone may be interested
Instead of being stuck on SaaS 1.0 apps, you’ll be working on Agentic AI
You’ll be redefining the future of work in a $bn industry (enterprise sales spend)
Fast – instead of being stuck at a slow company, you’ll be working with a small, highly technical team
Skills
Know prompting
Know SQL/Python well
Have a basic understanding of Frontend, good English, and interest in AI
Application process Given this is a founding role, there will be a comprehensive process spanning ~7‑10 fastest.
Intro call
– get to know Selix & the SellScale team.
Take home
– Build a full stack agentic app
Technical
– Pair‑program on your deliverable, back‑end leaning questions
Product & pace
– Walk through the non‑tech side of SellScale – filled with prototyping, WOZing, prompting, and more.
About SellScale SellScale is building the first agentic sales org.
Background:
At a business, you’re either
building
the product or
selling
it. Sales is the most expensive department – more than engineering, HR, marketing, and more, in large companies. (We wrote an article about it here!)
Problem:
As businesses grow larger, their sales spend grows disproportionately. Why? Sales—especially outbound—is still human‑driven: it’s subjective, hard to measure, and doesn’t scale like code. This is exactly the kind of problem agents are built to solve.
Opportunity:
With the advent of recent tech like agentic AI, large language models, vector DBs, and more – future sales is human x machine. Our agent, Selix, has already seen a lot of success.
Timing:
Right now, we are in the dot‑com boom of AI Agents. The agents we build help solve a businesses’s #1 problem: how to grow revenue. We use chained LLM thinking and start‑of‑the‑art GTM tools to help companies grow.
