Technical Lead / Senior Developer

Wiz-Team is the solution provider for Event and Games management software. From our head offices in Lausanne (Switzerland) and with registered subsidiaries in Italy, Belgium, Ukraine, and the USA and a global presence with our partners, we empower event managers with software, consultancy, and delivery services for world class events for the sport, corporate, and IGOs/NGOs industries. With over 15 years of experience in event management platforms and managing event-related projects, we pride ourselves into delivering real world solutions for your projects.

Reporting to Head of Operations and to the CTO, the Technical Lead will work with a distributed engineering organization across our European offices.

This role will own the technical evolution of one of our key products — a multi-tenant, multi-client platform serving major sporting clients during their most critical operational phases. The product is being prepared for broader sales readiness and migrated onto our next-generation Evo Platform (PHP/TypeScript microservices on Kubernetes). You will be the technical anchor of the pod, accountable for the codebase, the architecture, and the team's engineering practices.

This is a hands-on leadership role: you will write code, review code, and set technical direction while coaching engineers and improving how the team operates.
