Software Engineering Intern (Full Stack) – Summer 2027

Sage is a mission-driven software-enabled company focused on improving care and quality of life for older adults in senior living facilities. The Software Engineering Intern will join the product engineering team to ship production software, build frontend and backend features, write tests, participate in code reviews, and collaborate with product managers, designers, and engineers.

What you'll do:

• 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

What they're looking for:

• Strong programming fundamentals in at least one language, such as TypeScript, JavaScript, Java, or Python, with excitement to learn across the stack
• Evidence that you enjoy building things, through coursework, personal projects, open source, internships, bootcamps, or self-directed work
• Familiarity with web fundamentals, including APIs, HTTP, and databases
• Curiosity, initiative, and a willingness to learn quickly by asking thoughtful questions and acting on feedback
• Strong communication skills and enthusiasm for collaborating in an environment where ideas are shared and code is reviewed
• A genuine interest in building technology that serves people who are often overlooked by traditional software
• Experience with React, Node.js, or a JVM language
• Exposure to SQL or other databases
• Experience using AI development tools such as Cursor, Claude, GitHub Copilot, or similar, along with the judgment to review and understand the code they generate
• A project you're excited to demo, regardless of its level of polish
• Interest in healthcare, aging, or mission-driven technology

Benefits:

• Meaningful ownership of production software from day one
• A dedicated engineering mentor and regular, structured feedback
• A behind-the-scenes look at how a hardware-and-software company builds, ships, and supports products at scale
• The opportunity to present your work to the engineering organization and leave with real projects you can point to long after your internship ends
• Offsites, outings, and team meals
• Office lunch
• A fully stocked snack bar
• Up to 2 remote days per week
