Not by following industry playbooks, but by building our own, from 3D freight optimization algorithms to dynamic pricing engines. We're profitable, self-financed, and engineer-first by design.\nToday, we're bringing that same expertise into a new frontier: live sports and entertainment.\nYou'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.\nTicketing 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.\nYour missions\nLaunched 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.\nReporting 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.\nYou 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.\nTechnical vision & architecture\nDefine and maintain a global architecture vision (frontend + backend).\n\nOwn key technical decisions: refactoring, scalability, trade-offs between new features and technical debt.\n\nImprove collaboration across teams by breaking down existing communication silos.\n\nProject & product ownership\nDeeply understand the business and product context to make the right implementation choices.\n\nCollaborate with product owners to identify the most efficient path to delivery and ensure consistent planning.\n\nBe responsible for ensuring technical quality, performance, and maintainability.\n\nHands-on engineering\nOwn and deliver the most complex and critical parts of the codebase (frontend & backend).\n\nSet and enforce engineering best practices through code reviews, pair programming, and direct contributions.\n\nLead by example on architecture, code quality, and performance - your code is your most powerful lever.\n\nTeam leadership & coordination\nSupport and coach the existing developers to grow their skills and autonomy.\n\nFacilitate technical alignment between frontend and backend teams, breaking down silos.\n\nBe the main technical interface with Product Owners and leadership, translating business needs into sound technical decisions.\n\nTechnical stack:\nBackend: Python 3.7+, SQLAlchemy, Remoulade (in-house task queue), GraphQL APIs\n\nFrontend: Next.js (front office), Angular (back office), TypeScript, D3.js\n\nData-store: Postgresql, Elasticsearch, Redis\n\nGitlab for continuous delivery\n\nKubernetes for infrastructure\n\nPrometheus/Grafana and Kibana for operations\n\nYour profile\nYou have 7+ years of experience in software engineering, with a strong track record as an Individual Contributor on complex products.\n\nYou are primarily a builder: you love writing code, solving hard technical problems, and raising the quality bar through your own output.\n\nStrong fullstack background with a backend-first mindset (Python), fully comfortable owning frontend work (Next.js or equivalent).\n\nYou have led or mentored engineers before, but your first instinct is still to dive into the code.\n\nGood communication skills, able to collaborate with Product and align technical decisions with business priorities - without spending most of your time in meetings.\n\nBonus: Experience in SaaS, event-tech, or working on complex interfaces and operations-heavy B2B2C products.\n\nYou have a native or fluent level in French\n\nOur benefits\nBy joining us, you will integrate:\nA self-financed startup with a strong tech identity!\n\nBeautiful 800 m² offices in the heart of Paris (Bd Poissonnière)\n\nAttractive remuneration indexed on performance\n\nA caring and stimulating team that encourages skills development through initiative and autonomy\n\nA learning environment with opportunities for evolution\n\nYou will also benefit from:\nA hybrid policy: 2 days of remote work per week and the possibility to work occasionally from abroad\n\nAccess to WellPass at a preferential rate to maintain your well-being\n\nA great company culture (monthly afterworks, regular meetings on technology and products, annual off-site seminars, team-building…)\n\nOur Recruitment Process\nA screening interview with Anne-Laure our Lead Talent Acquisition Manager\n\nA screening interview with Charles our CTO and Co-founder\n\nA Use case to be prepared\n\nA technical interview with Charles and a team member\n\nFounder interview with our CEO\n\nWiremind is committed to equality of opportunity, diversity, and fairness.
