The Opportunity

8x Social is building the infrastructure for performance-driven creator marketing. We connect brands with 100k+ creators across 30+ countries, and we're automating the entire pipeline with AI - from creator discovery to campaign evaluation to payout.

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
  • Campaign automation pipelines. replacing manual ops with intelligent workflows
  • Internal tools and dashboards. that make our team 10x more efficient every quarter
  • Whatever needs building. - at this stage, the best idea wins regardless of who proposed it
III.

Who You Are

You are the type of person who shipped side projects, competed in olympiads, or built things that make people stop and ask how you did them. You have strong CS fundamentals from a top program, competitive programming, or independent proof of raw ability, and you are dangerous with code.

  • 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

  • Performance bonuses. meaningful upside tied to shipping and business outcomes
  • Direct access. - sit next to Theo (CTO, Imperial College) in SF and build together daily
  • Massive scope. - own entire product areas from week one
  • Trial structure. 2-month paid internship to make sure the fit is right on both sides, then full-time 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.
