Cloudflare's Billing Engineering team builds and maintains all the internal/external billing services related to customer onboarding, subscription management, payments, provisioning, usage processing/analytics and back office integrations with financial systems.

You will work on a range of transactional microservices written in Go. You will be involved in helping to maintain our operational excellence by triaging, solving various inbound tickets related to issues across services billing maintains. As you grow within the team you will be given opportunities to own bigger initiatives and lead projects from start to finish solo or as part of a smaller team.
