Job description

Sage is on a mission to improve care and quality of life for older adults, starting with those residing in senior living facilities. Falls are the leading cause of injury-related death among adults over 65. At Sage, we've built a more modern way of understanding when older adults need help, including methods for residents to alert caregivers when in need of help, and corresponding software for caregivers to triage response.

Our company mission is to create a product that our client counterparts love, and this role is a key part of that objective. Sage is a small, tight team of ambitious, multi-disciplinary entrepreneurs. We are a software-enabled, mission-driven company, and are focused only on the problems that are central to achieving that mission.

About this Role

As a fullstack engineer on Detect, you'll be at the forefront of bringing AI-powered insights to life for caregivers and facility staff. You'll build the critical user experiences in our Care App that transform AI detection events into actionable workflows that save lives - creating intuitive interfaces for reviewing and escalating fall events, building sophisticated alerting and notification systems, and developing tools that help caregivers respond faster and more effectively.

Responsibilities

• Build simple, intuitive status indicators and operational dashboards that give facility managers and caregivers real-time visibility into resident activity and safety events
• Develop sophisticated post-detection workflows in the Care App that enable caregivers to quickly triage AI-detected events, escalate true emergencies, and coordinate team responses
• Create flexible alerting and notification systems that allow communities to configure custom rules for resident behaviors like bed exits, unit departures, or balance concerns
• Enhance video review capabilities to improve how authorized staff access, annotate, and share fall events while maintaining privacy and security
• Implement performant full-stack features using React, TypeScript, and Java/Kotlin, ensuring seamless data flow from backend AI services to user-facing applications
• Collaborate with design and product teams to create interfaces that make complex AI capabilities approachable for non-technical users

Minimum Qualifications

• 5+ years of professional fullstack development experience
• Experience with backend development in Java, Kotlin, or similar languages
• Track record of building responsive, accessible web applications
• Experience with RESTful API design and integration
• Demonstrated ability to work across the full stack and ship complete features

Preferred Qualifications

• Experience translating complex data or AI-generated insights into intuitive, user-friendly interfaces
• Background in building workflow management or escalation systems
• Experience with Dropwizard, Spring Boot, or similar JVM frameworks
• Track record of building mobile-responsive web applications for non-technical users
• Experience working with healthcare, senior care, or other mission-critical applications
• Familiarity with privacy and security best practices for sensitive data

Benefits and Pay

We offer competitive base compensation along with stock options. The expected annual salary range for this role is $190,000-245,000 USD, depending upon the job level, which will depend on your level of expertise, your experience, and your qualifications. We also provide fully-paid health and dental insurance coverage for all of our employees, along with other health benefits including vision insurance, membership to premium primary and urgent care, and online medical health providers.
