Take ownership of the entire lifecycle of your services, including automated testing, deployment, monitoring, and operational support. Proactively identify and resolve root causes of issues to ensure service reliability and performance. • Risk & Control Management: Adhere to Citi's technology standards and risk management frameworks. Identify, assess, and mitigate risks in your designs and code, ensuring all solutions are compliant with security policies and data regulations. • CI/CD & Automation: Implement and maintain CI/CD pipelines to automate the build, test, and deployment processes, enabling rapid and efficient delivery of new features and fixes. • Collaboration & Code Quality: Actively participate in code reviews and adhere to the Developer Manifesto principles, including owning your code, writing meaningful commit messages, and maintaining a clean and tidy repository. Collaborate across teams to promote reuse and reduce duplication.
