Medicheck is a Belgian platform that helps companies tackle absenteeism through medical checks for employees on sick leave (~3,500 checks a month). There the role goes beyond code: working as a product engineer, taking part in architecture and product decisions, and owning the maintenance and evolution of the infrastructure (GCP, Azure, GitHub Actions) and codebase (Next.js, .NET): bug fixes, upkeep, new features, security, performance and audits.
