Role
Who you are
- 5+ years of professional fullstack development experience
- Strong proficiency in modern JavaScript/TypeScript and React
- 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
Desirable
- Experience translating complex data or AI-generated insights into intuitive, user-friendly interfaces

- Track record of building mobile-responsive web applications for non-technical users

What the job involves
- 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
- This is an opportunity to shape how thousands of caregivers interact with cutting-edge AI technology, making it accessible, understandable, and actionable
- You'll work across the full stack, from crafting responsive React interfaces to building robust backend services, bridging the gap between our AI capabilities and the caregivers who depend on them every day
- 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
Our take
In the event of an accident or fall, elder care facilities largely rely on outdated nurse call systems, which can mean residents wait longer than necessary to receive care or attention. Sage solves this problem by providing carers and institutions with a modern operating system.
Sage's caregiver app allows carers to identify patients in need of help, as well as providing tools for triage and the reviewing of care information. As one of the first companies to bring a data-driven approach to elder care in this way, Sage has received strong attention and raised an impressive $35 million in funding in 2024.
The age-tech market is growing steadily, and becoming more competitive, which means Sage will need to invest heavily in scaling its outreach in order to consolidate its progress. That said, it has established an early foothold which gives it a place to work from as it develops into the future.
