Founding Engineer – Full-Stack (Vue / Nuxt) – CDI

About

👩‍🚀 Help us reshape how billions are negotiated

Procurement is how large companies source and negotiate with suppliers — and it’s one of the last major business functions still running on spreadsheets, emails, and outdated tools.

At CROWN, we’re reinventing this through real-time electronic auctions (eAuctions) that drive speed, transparency, and +6% incremental savings.

Our platform, CROWN MACHINE, lets buyers from top European companies run multi-million-euro auctions every week. We’re already working with leaders like Bonduelle, Kiabi, and Innovie, and we’ve processed tens of millions of euros in auction volume.

Now, we’re scaling fast — and we’re hiring our first in-house engineer to help lead the charge.

Job Description

👑 About Us

CROWN was founded by Mykyta Voytenko, a procurement expert with 15+ years at Nestlé, Sanofi, and Engie. We’re a team of 10 based in Paris, combining deep industry knowledge with startup speed.

In just 12 months, we’ve:

  • Built and shipped a high-performance SaaS platform

  • Secured €1M+ in projected revenue

  • Raised 2M+ funding from top-tier investors: Kima Ventures, Heartfelt, Backbone

  • Signed multiple enterprise clients and are growing rapidly

It’s working — and that’s our biggest pride. Clients love what we do, and we’re building something that’s delivering real impact.


🎯 Your Mission: Founding Engineer

You’ll be the technical owner of our product — the core person behind the architecture, performance, and evolution of our full-stack platform. It’s a hands-on role, where your code and decisions will directly shape the future of B2B negotiation tech.

We’re looking for someone to take over from our excellent external dev team (phasing out in 6 month), work closely with the founder and ops team, and build the next generation of features — fast, cleanly, and smartly.

This is an individual contributor role at first — but with the potential to evolve into CTO and build your own team as we grow.


🛣️ What’s Next: Our Roadmap

We’ve already developed 18 types of eAuctions, giving buyers powerful levers to run better negotiations. Next up:

  • AI-driven Auction Builder: Our vision is a feature that reads incoming RFPs (Requests for Proposals) and recommends the best negotiation strategy — then configures it directly in the platform.

  • Smarter Automation: Enriching auction logic, pricing intelligence, and bidder behavior with optimization algorithms and LLMs.

  • End-to-End Procurement Workflow: Eventually, we aim to become the central cockpit for sourcing — keeping negotiation at the heart, but offering clients an integrated, seamless experience.

It’s an ambitious roadmap — and your role is to bring it to life.
