The summary above was generated by AI

We're building an AI Front Office that autonomously runs businesses. Working alongside technical founder Kai Feller (previous company was UK’s largest bootstrapped exit of $300m), we're assembling an elite founding team that moves fast and gets things done.

As a Software Engineer, you’ll ship step-changing features fast, shaping architecture, and integrating cutting-edge AI directly into the product. You’ll design & build the scalable backend systems and intelligence layers that enables the autonomous running of thousands of businesses. This is an engineering role at its best - building what’s never existed before hands-on within a small & exceptionally talented group, that operates with a sense of urgency and passion for building innovative products.

What you’ll do

  • Build new step-changing product features end-to-end, shipping fast and often.

  • Integrate cutting-edge AI directly into the product - voice, reasoning, context management, data extraction - turning static workflows into living intelligence.

  • Design, build & own APIs that scale internally & externally to connect products, integrations, and intelligence systems together.

  • Architect robust data flows & pipelines that fuel agent context & decision making.

  • Develop backend infrastructure and intelligent automation for knowledge crawling, extraction and enrichment.

  • Help shape and contribute towards our DevOps practices (CI/CD, cloud infrastructure, observability).

Requirements

  • Deep full-stack Javascript expertise or deep backend Python expertise (we have an open role for both).

  • High-agency - you own projects end-to-end and make decisions with imperfect information.

  • Strong sense of ownership - you care deeply about your work and what we deliver to customers.

  • Track record shipping - you know what it takes to rapidly ship production ready features.

  • AI fluency - you know how to use AI tools to make yourself ridiculously efficient.

  • Excellence everywhere - everything you apply yourself to is done to the highest of quality with top results. We are building a team of winners.

Why join

  • Share options - Everyone gets equity. But unlike most, our share options translate into real value as we’ve paid them out before.

  • High pay & stability - We pay top salaries and offer tangible equity. You don’t have to trade security for upside.

  • Tools for the job - Whatever helps you be more productive, you get it. The best hardware, software, and setup. We love technology.

  • Proven winning team - We’ve built, scaled, and sold large successful businesses before. Now we’re hands-on building again.

  • Warchest available - We have our own significant funds available if required. No external shareholders, no external distractions.
