Founding Full Stack Engineer

We’re hiring on behalf of a high-growth, YC-backed startup that’s transforming how modern sales teams operate — and they’re looking for a Founding Full Stack Engineer to join at the ground floor.

You’ll be one of the first engineers on the team, working directly with the founders to build and ship customer-facing features powered by generative AI.

This is a rare opportunity to shape product, culture, and architecture at a pivotal stage — with a team already backed by top-tier VCs and scaling toward $1M+ in ARR.

What you’ll do:

Build high-performance, user-facing features in React, TypeScript, Python

Help design and integrate LLM-powered functionality across modalities (text, image, audio, video)

Work cross-functionally with design, product, and backend to deliver end-to-end features

Deeply understand customer needs and rapidly iterate to improve UX

We’re looking for:

5+ years of experience in full-stack development

Expertise in React + TypeScript and backend development in Python

Strong grasp of APIs, databases, and infrastructure (e.g. Terraform, AWS)

Experience with automated testing frameworks

Bonus: interest or experience in generative AI

A collaborative, practical, and customer-obsessed mindset

Perks include: competitive compensation, meaningful equity, and the chance to be part of a team building cutting-edge AI tools from the ground up.

If you're a builder excited by early-stage momentum and ready to make an outsized impact, let’s talk.
