Founding Engineer

I’ve co-founded a company that grew to over €15M in annual revenue. I’ve lived the journey -building teams, scaling operations, closing deals.

This time, I’m looking for a sharp, pragmatic technical partner to join as Founding Engineer. I need someone who's been through this before - someone who's taken a meaningful scale and knows what breaks at 10 customers vs. 100 vs. 1,000 vs 10,000.

Core technical challenges/What you would be building:

Document intelligence + data transparency platform.

• Intelligent document processing – Extract structured data from unstructured PDFs at scale
• Embedded widget system – Think Trustpilot's badge, but for real-time verified data. Stripe started with payment buttons, became payments infrastructure. We're doing similar in our vertical.
• Verification pipeline – Automated validation + human-in-the-loop workflows
• Multi-tenant data platform – Thousands of brands uploading documents, millions of customers viewing results
• Two-sided marketplace infrastructure – Connecting two sides of a market.

What I’m looking for:

• You've scaled at companies before.
• Full-stack experience.
• You make architectural decisions. You say "we should build X, not Y" and can defend why. You're not executing someone else's roadmap.
• I'm in sales calls. You and your team is building. We sync daily, ship weekly, review monthly. You work autonomous.

Nice-to-haves:

• Document processing / PDF extraction / parsing / with AI models experience.
• Built embeddable widgets or integrations

Tech Stack:

• Ruby Rails + Vanilla JS + PostgreSQL + Redis

What’s in it for you:

• True founding status - salary & equity.
• A trusted business partner who brings go-to-market experience, investor network, and full-time focus.
• A real shot at building something impactful.
