This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.
The role
Instead of selling SaaS to legacy industries or orchestrating traditional private equity roll-ups, this company rebuilds entire legacy enterprises from scratch as AI-native businesses run by a single operator. Backed by leading European venture funds, they scaled past eight figures in annualized revenue in under a year while sustaining over one million dollars in revenue per employee. As a Founding Engineer, you are building the central platform that runs these companies. This is not a ticket‑taking feature‑factory role, nor is it an academic prompt‑engineering sandbox. You will own the core systems architecture end to end, deploying autonomous agents and automated workflows that directly power tens of millions in live commercial revenue.
The work
- Architect and scale the central software engine used to launch and run full‑scale AI‑native enterprises from scratch.
- Design, deploy, and maintain autonomous agents and LLM‑driven workflows that replace entire operational layers of legacy businesses.
- Own system performance, reliability, and business outcomes end to end across systems processing tens of millions in real revenue.
- Collaborate directly with business operators to translate manual operational playbooks into autonomous, resilient software infrastructure.
What You Bring
- Track record of designing, building, and running complex production software systems end to end.
- Hands‑on experience architecting AI‑native systems, autonomous agents, or complex LLM‑driven operational workflows.
- An owner mindset focused on commercial outcomes and system architecture rather than a narrow slice of a codebase.
- Commitment to a high‑intensity, fully in‑person culture five days a week in London.
