## Job description

Eigen is looking for outlier AI Platform Engineers to help build the future of human connection. You must have experience designing large yet maintainable AI systems, and be excited to do so about 3 times faster than most people think is possible.

We are well-capitalized and backed by Peter Fenton (Benchmark), David Singleton (ex CTO, Stripe), Gustav Söderström (CEO, Spotify), and only hire the best. Expect talented, thoughtful colleagues and a work environment that’ll expect you to do your best work every day.

## What you'll do

## About Eigen

## Company Overview
- **One-liner**: Eigen is building an AI-powered platform that creates a shared “mutual friend” to help people connect, belong, and grow together through synchronous experiences.
- **Entity Type**: Private (Seed stage – raised $15M)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2025
- **Founders**: Paul Scherer (Chief Inventor, CEO)

## Core Business
- **Primary industry**: Artificial Intelligence / Social AI Platform
- **Target customers**: B2C (individuals seeking meaningful human connection); also B2B potential for community building
- **Mission / purpose**: To invent the internet’s shared friend and transform how people relate to technology and each other, combating social isolation.

## Products & Services
- **Eigen AI Platform**: An AI-powered “mutual friend” that facilitates real-time, shared experiences among multiple users, rather than hyper-personalized one-on-one AI companions. The platform is designed to foster genuine human connections and reduce loneliness.

## Market Standing
- **Valuation / Market Cap**: Not disclosed
- **Key Metric**: Total Funding $15M (Seed round, April 2026)
- **Notable Investors / Partners**: Lead investor: Benchmark. Angel investors include Ben Silbermann (Pinterest co-founder), Gustav Söderström (Spotify CTO), and David Singleton (Stripe CTO).
- **Growth Signals**: Early-stage startup with 4 employees and rapid LinkedIn follower growth (31.5% monthly). Founder Paul Scherer is a self-taught coder who previously scaled a Paris-based startup. The company is targeting a massive market: half of U.S. adults report feeling isolated.

## Competitive Advantages
- **Contrarian approach**: Focuses on shared, synchronous experiences rather than individual AI companions (differentiating from Replika and Character.ai).
- **Founder-driven vision**: Paul Scherer’s unique background (rural German village, self-taught) and emphasis on collective belonging.
- **Strong investor backing**: Benchmark’s involvement signals confidence in the team and market thesis.

## Strategic Focus
- **Current priorities**: Hiring a Member of Technical Staff for AI Product and AI Platform roles; building the core product and scaling the engineering team.
- **Growth direction**: Expanding from a small, focused team into a larger organization that can deliver on the “mutual friend” vision and capture the growing AI companion market.

## Why Work Here
- **Culture highlights**: Early-stage startup with a mission to reduce social isolation – a deeply human-centric purpose. The team is small (4 people) and values technical excellence.
- **Remote / hybrid policy**: Hybrid workspace. Employees are expected to work on-site in San Francisco (typically in-office, but some remote flexibility is implied).
- **Notable perks**: Opportunity to work directly with the founder and shape the product from day one. High-impact role in a well-funded seed-stage company with top-tier investors.
