Founding Engineer

Department: Engineering

Location: London

Employment Type: FullTime

We’re building the AI layer that autonomously runs small 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 Founding 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 businesses before (UK’s largest bootstrapped exit of $300m). Now we’re hands-on building again.

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