100k+ Creators in network

30+ Countries

We're at $3M+ run rate and we're just getting started. The product is working. The market is pulling. Now we need a software engineer who wants to build the future of this industry, not maintain someone else's legacy systems.

What You'll Build

This is not a ticket-taker role. You'll own entire systems from architecture to deployment.

• AI-powered evaluation systems. that score creator content and predict campaign performance
• Creator matching infrastructure. connecting the right creators with the right brands at scale

• Internal tools and dashboards. that make our team 10x more efficient every quarter

Who You Are

• Builder mentality. - you ship fast, learn faster, and care deeply about craft
• Strong CS fundamentals. - top school, competitive programming, or equivalent proof of raw ability
• Full-stack capability. - comfortable across the entire stack from database to deployment
• AI-native thinking. - you already use AI tools daily and think in terms of what's now possible
• Startup conviction. - you want early-stage impact, not big-company comfort

We're looking for brilliant engineers before they get scooped by Google or Jane Street. If you want to build something that matters with a small, exceptional team - this is your moment.

What You'll Get

• Part-time: $1,500-$3,000/month. base for a 25-hour weekly commitment
• Full-time. competitive salary depending on experience, plus stock options on conversion

Our founders: Jaka Bavdek (CEO, London Business School) and Theo Bui (CTO, Imperial College). We came out of Entrepreneur First and built the fastest-growing company in the program's history. We're small, focused, and moving very fast.
