Job description

About us
The first baby boomers turn 80 this year. Over the next decade, the population most likely to need daily care will grow faster than the buildings, the staff, or the systems available to serve it.
Sage is the care intelligence platform for senior living and skilled nursing. We connect the hardware senior care runs on, including nurse call, fall management, and wander management, with software caregivers actually use. That consistent use is what produces reliable data, and reliable data is what gives operators a true picture of how their communities are running.
Sage is a collaborative team of ambitious, multi-disciplinary entrepreneurs on a mission to reinvent senior care with a modern operating system for caregivers. Millions of people depend on this care getting better, and we move with the urgency that deserves.
About this role
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.
This internship runs Monday, June 7, 2027 to Friday, August 13, 2027.
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.
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

Minimum Qualifications
  • 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

Preferred Qualifications
  • 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

What You'll Get
  • 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

Compensation
Our headquarters are located near New York City's Union Square. We believe in cross team collaboration. We think good ideas can come from anyone, and we've designed our processes to encourage participation from all. While we take our mission seriously, we don't take ourselves too seriously. We like to host offsites, outings, and team meals where we can connect as people, not just as colleagues. We offer office lunch and a fully stocked snack bar. While we are an in-office culture, we allow up to 2 remote days per week.
This role is paid at $50/hour. As an internship position, it is not eligible for our standard employee benefits package (health insurance, stock options, PTO, etc.).
EEO Statement
Sage is an equal opportunity employer that is committed to diversity and inclusion in the workplace. We prohibit discrimination and harassment of any kind based on race, color, sex, religion, sexual orientation, national origin, disability, genetic information, pregnancy, or any other protected characteristic as outlined by federal, state, or local laws.
This policy applies to all employment practices within our organization, including hiring, recruiting, promotion, termination, layoff, recall, leave of absence, compensation, benefits, training, and apprenticeship. Sage makes hiring decisions based solely on qualifications, merit, and business needs at the time.
