Role

SellScale is building Selix.ai, an virtual teammate that will handle your entire team’s outbound end to end.

We are looking for our next Remote  Full Stack Software Engineer. This position will be shipping across the stack - backend, frontend, and database. You will quickly get involved with shipping AI/agentic features.

Requirements

1. AI interest - including with agentic apps. Production AI experience not required. But, this should not be your first time making an agentic app or calling LLM APIs. Hackathons and extensive side projects are OKAY 👍.

2. Remote / Bangalore - you will specifically be working during daytime India (overnight from PT) to help shipping velocity - join our expanding Bangalore team!

3. Solid CS fundamentals - an undergrad degree in CS, and able to ship across the stack:

   • Front-end: React/Typescript

   • Back-end: Python (e.g., Flask, FastAPI, or Django)

   • Database: SQL experience (e.g., Postgres)

4. Early stage only - interest to join a startup as one of the first N employees

Reasons to think twice about applying…

🙅 You are looking for “senior leadership” guidance - be ready to solve your own problems!

🙅 You don’t want to code - this role is only about shipping!

🙅 You’re looking for larger companies - this is an early, tight, technical team!

Positives

💡 You will make decisions that will take you 10 years at Google to do

💡 There are few other places where you will learn more about building in an agentic / AI than here

💡 You will have a driver’s seat in an Agentic AI startup in the heart of SF, with a mult $bn TAM - enterprise sales spend

Skills

• Fearlessly works across the entire stack (backend / frontend / design / infra / tooling )

• Strong Python, JavaScript, React, React Native, Flask, PSQL, and LLM-prompting skills.

• Great prompting and knowledge of agentic systems (including building your own from scratch)

• Strong communication skills for our non-technical userbase, and very technical team

• Strong English as sales, prompting, and LLMs, all deal with language and what to say

Application process

A well-rounded application to test across the stack and against team culture.

1. Application process - submit this application

2. Live call - interview with our CTO

3. Work trial - take a few tickets from our backlog and knock them out

The stack

✅ Front-end: React/Typescript

✅ Back-end: Python (Flask)

✅ Database: PostgresSQL

About SellScale

SellScale is building the first agentic revenue org.

Background: At a business, you’re either building the product or selling it. Enterprise sales spend is a multi-$bn market.

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 like agentic AI, large language models, vector databases, 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.
