Licorne Society a été missionné par une startup en pleine croissance pour les aider à trouver leur CTO hands-on.

🚀 Join a fast-growing B2B SaaS company reinventing how Europe’s largest enterprises negotiate 🚀

📍 Location: Paris, France (mostly in-person)

🖥 Start Date: Q1 2026

✍️ Contract Type: Full-time (CDI)

💰 Compensation: Fixed salary + bonus + equity (BSPCE-equivalent)

🌍 Help reshape how billions are negotiated

Enterprise procurement teams negotiate millions every week — yet the negotiation layer remains fragmented, manual, and poorly tooled.

We are building a cloud-based platform that enables large organizations to run eAuctions and structured eNegotiations with speed, reliability, and strong governance. The platform is already used by multiple tier-1 industrial and retail groups and has processed €100M+ in GMV.

We are now internalizing our core engineering and laying the technical foundations for scale. As our first in-house engineering leader, you will take ownership of the core IP and architect the future of a mission-critical B2B product.

🎯 Your role

You will be the technical owner of the platform.

This is a hands-on leadership role: you will write production code, make key architectural decisions, and progressively build the engineering function.

You will take over from a strong external development team, ensure a smooth knowledge transfer, and set the company up for long-term product velocity and enterprise-grade reliability.

🧭 What you will own

* End-to-end platform architecture (frontend, backend, data, infrastructure)

* Production reliability for real, high-stakes enterprise workflows

* Security, auditability, and data protection for sensitive procurement data

* Engineering standards, delivery cadence, and future hiring roadmap

🏗️ About The Company

We are a Paris-based B2B SaaS startup (team of ~6) combining deep procurement expertise with startup execution speed.

In The Past 12 Months, We Have

* Built and shipped a high-performance SaaS platform

* Secured €1M+ in projected revenue

* Raised €2M+ from top-tier European venture funds

* Signed multiple enterprise customers and are scaling rapidly

The product is live, used daily, and delivering tangible value — customer satisfaction is one of our strongest signals.

🛣️ Product & technical roadmap

We have already built 18 types of eAuctions, giving buyers advanced levers to run better negotiations. What’s next:

* AI-driven Auction Builder

* A system that reads incoming RFPs and recommends the optimal negotiation strategy — then configures it directly in the platform.

* Smarter automation

* Enhanced auction logic, pricing intelligence, and bidder behavior analysis using optimization algorithms and LLMs.

* End-to-end procurement workflow

* Becoming the central sourcing cockpit, with negotiation at the core and a seamless, integrated enterprise experience.

✅ What success looks like

First 30 days

* Full audit of codebase and infrastructure, with a clear risk map and action plan

* Knowledge transfer completed with the external team

* Monitoring, error tracking, and release processes stabilized

Days 30–90

* Measurable improvements in performance and reliability

* Clear architectural direction documented

* First key roadmap features shipped end-to-end

After 3–6 months

* Strong delivery cadence, fewer incidents, faster iteration

* Hiring and onboarding plan defined and first hire(s) made if needed

🛠️ Current tech stack

* Frontend: Nuxt 3, Vue, Vuetify

* Backend: Nuxt 3 (Nitro)

* Database: PostgreSQL (Supabase)

* Hosting: Vercel

The stack can evolve as we scale — with a strong preference for pragmatic decisions that protect delivery speed.

🧩 What we are looking for

✅ Must-haves

* Strong full-stack background with true ownership of production systems

* Solid experience with Vue and Node.js (Nuxt is a big plus)

* Strong PostgreSQL fundamentals (Supabase experience is a plus)

* Experience building and operating a demanding B2B SaaS product

* High bar for reliability, performance, clean architecture, and security

* Comfortable working autonomously and making tradeoffs

✨ Nice-to-haves

* Previous experience leading or mentoring engineers (formally or informally)

* Built workflow-heavy or real-time systems

* Integration mindset (ERP, SAP-like systems, SSO, audit trails, exports)

* Interest in AI-enabled product features and automation

🏢 Work setup

We are looking for someone based in Paris or willing to work mostly in person.

Remote days are flexible, but we strongly believe that early-stage momentum is built through close, live collaboration, mainly from our offices at Station F and Châtelet.
