Head of Software Engineering Hands-on (M/F) - CDI - Paris

Empty seats on trains. Unsold stadium tickets. Every day, the transport and events industries lose immense value due to outdated systems, blind forecasting, and rigid pricing.

Founded in 2014, Wiremind is a fast-growing SaaS company specializing in inventory, ticketing and revenue management. Combining deep industry expertise with AI, data science and a modern UX, we help our clients sell their capacity across every channel and by setting the right price.

We partner with leading rail operators, airlines and event organizers to transform their commercial performance via machine-learning-powered demand forecasting and agentic automation, decision-ready visualizations, and intuitive interfaces for end users, driving customer loyalty and engagement. Our applications have become the tool of choice for more than 50 clients across more than 10 countries worldwide, from passenger transport operators such as SNCF, Transavia, VIA Rail Canada and Eurostar to sports clubs such as PSG, Angers SCO and Élan Chalon, to manage their inventory, sell tickets across every channel, and optimize their pricing on a daily basis.

Today, Wiremind has 170 employees and has been profitable and 100% bootstrapped since day one. We are a team of experts driven by engineering excellence and product impact.

You'll join Eventori our all-in-one ticketing platform built for sports clubs and live entertainment venues. Access control, front office, CRM, resale, revenue management: one product, one 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, Eventori is entering a clear acceleration phase. We're looking for a Head of Software Engineering who wants to own the technical foundations of a product that will redefine how sports clubs fill and monetize their stadiums.

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.
