• Proven experience designing, building, and operating backend services or internal platforms in production environments.
• Strong understanding of API design, service-to-service integration, and backend architecture.
• Experience working in cloud environments, ideally AWS.
• Experience with containers and related tooling, for example Docker.
• Familiarity with CI/CD practices and modern engineering workflows.
• Good communication skills and the ability to work effectively across security and engineering teams.
