• Own the testing lifecycle for your features—writing unit tests with Jest and end-to-end tests with Cypress.
• Investigate and resolve production issues, improve observability, and contribute to platform reliability.
• Partner with DevOps and infrastructure teams to ensure smooth deployments, CI/CD workflows, and system performance.
• Stay up-to-date on industry trends and best practices, and proactively introduce improvements to tools, processes, or technologies.
