What the job involves

• As a Software Engineering Intern at Sage, you'll join a product engineering team as a full member from day one. You'll attend the same standups, contribute to the same roadmap, review the same pull requests, and ship to the same production codebase as the rest of your team
• The software you build supports caregivers responding to real residents in real moments of need. Every feature, bug fix, and improvement has the potential to make someone's day easier, and someone's care better
• Throughout the internship, you'll work closely with an experienced engineer who will mentor you, help you grow, and give you meaningful feedback. By the end of the summer, you'll have shipped production software and shared what you built with the broader engineering organization
• Ship production code as part of a product engineering team, from your first pull request through deployment
• Build user-facing experiences in React and TypeScript used every day by caregivers and senior living communities
• Develop backend services in Java that power care workflows, notifications, and integrations with the systems our customers rely on
• Write tests, participate in code reviews, and iterate on feedback as part of our engineering process
• Partner with product managers, designers, and engineers to scope, build, and deliver meaningful features
• Learn what it takes to build and operate reliable software that people depend on every day
