Description du poste

Wiremind is a tech company built around a single idea: helping transport and event operators make smarter decisions about their capacity, pricing, distribution, forecasting, optimization.

Since 2014, we’ve built the tools that power revenue management at SNCF, United Airlines, Qatar Airways and PSG. We’ve created our own solutions, from 3D freight optimization algorithms to dynamic pricing engines. We’re profitable, self‑financed, and engineer‑first by design.

Today, we’re bringing that expertise into a new frontier: live sports and entertainment.

You'll join Eventori, our all‑in‑one ticketing platform built for sports clubs and live entertainment venues. It provides access control, front office, CRM, resale, revenue management: a single product, a single stack powered by machine learning and dynamic pricing.

Ticketing is a massive, largely untapped market. Most clubs still rely on static pricing and fragmented tools, leaving serious money on the table. We’re changing that, bringing to sports the same revenue intelligence we’ve spent years perfecting for airlines and rail operators.

Your Missions

Launched in 2022 and now live with Ligue 1 club SCO Angers, Eventori is entering a clear acceleration phase. We’re looking for a Lead Software Engineer who wants to own the technical foundations of a product that will redefine how sports clubs fill and monetize their stadiums.

Reporting directly to Charles, Wiremind’s CTO and Co‑founder, you will be a highly hands‑on technical leader, owning both the architecture and a significant share of the most complex development work. You will spend ~70 % of your time as an Individual Contributor (writing code, leading critical technical challenges, and setting the quality bar) while dedicating ~30 % to coordination, mentoring, and bridging product, engineering, and leadership teams.

You will collaborate closely with our existing Frontend and Backend Leads and Developers, Product Owners, and Sales to ship scalable, quality‑first solutions that meet the specific business needs of the event industry.

Technical Vision & Architecture

• Define and maintain a global architecture vision (frontend + backend).
• Own key technical decisions: refactoring, scalability, trade‑offs between new features and technical debt.
• Improve collaboration across teams by breaking down existing communication silos.

Project & Product Ownership

• Deeply understand the business and product context to make the right implementation choices.
• Collaborate with product owners to identify the most efficient path to delivery and ensure consistent planning.
• Be responsible for ensuring technical quality, performance, and maintainability.

Hands‑On Engineering

• Own and deliver the most complex and critical parts of the codebase (frontend & backend).
• Set and enforce engineering best practices through code reviews, pair programming, and direct contributions.
• Lead by example on architecture, code quality, and performance — your code is your most powerful lever.

Team Leadership & Coordination

• Support and coach the existing developers to grow their skills and autonomy.
• Facilitate technical alignment between frontend and backend teams, breaking down silos.
• Be the main technical interface with Product Owners and leadership, translating business needs into sound technical decisions.

Technical Stack

• Backend: Python 3.7+, SQLAlchemy, Remoulade (in‑house task queue), GraphQL APIs
• Frontend: Next.js (front office), Angular (back office), TypeScript, D3.js
• Data‑store: Postgresql, Elasticsearch, Redis
• Gitlab for continuous delivery
• Kubernetes for infrastructure
• Prometheus/Grafana and Kibana for operations

Your Profile

• You have 7+ years of experience in software engineering, with a strong track record as an Individual Contributor on complex products.
• You are primarily a builder: you love writing code, solving hard technical problems, and raising the quality bar through your own output.
• Strong full‑stack background with a backend‑first mindset (Python), fully comfortable owning frontend work (Next.js or equivalent).
• You have led or mentored engineers before, but your first instinct is still to dive into the code.
• Good communication skills, able to collaborate with Product and align technical decisions with business priorities — without spending most of your time in meetings.
• Bonus: Experience in SaaS, event‑tech, or working on complex interfaces and operations‑heavy B2B2C products.
• You have a native or fluent level in French.

Benefits

• A self‑financed startup with a strong tech identity.
• Beautiful 800 m² offices in the heart of Paris (Bd Poissonnière).
• Attractive remuneration indexed on performance.
• A caring and stimulating team that encourages skills development through initiative and autonomy.
• A learning environment with opportunities for evolution.
• A hybrid policy: 2 days of remote work per week and the possibility to work occasionally from abroad.
• Access to WellPass at a preferential rate to maintain your well‑being.
• A great company culture (monthly after‑works, regular meetings on technology and products, annual off‑site seminars, team‑building).
