Senior​/Software Engineer - Edge

About Us

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. And yet, fall prevention and emergency response systems for older adults are archaic and ineffective. 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. At Sage, we work hard and fast but also know that to build a truly important company, we need to treat our work as a marathon, and not a sprint. The journey matters.

As a Senior/Staff Backend IoT Engineer, you will be a technical leader responsible for bridging physical systems at senior living communities with the cloud computing infrastructure that powers the Sage platform. You will define the architectural direction for our edge computing systems and drive technical decisions that impact the entire organization. You will work closely with Engineering, Product, and Implementation teams to help create the next generation of software/hardware solutions that revolutionize care in senior living.

Beyond individual contribution, you will mentor engineers across the team, establish engineering best practices, and serve as a key technical voice in company-wide strategic decisions.

You will have the opportunity to own multiple projects (e.g., fall detection, location tracking technology, integration with third‑party hardware). Your contributions to the edge and backend technology stacks will directly impact the ability to scale the adoption of Sage's offerings and improve the senior living industry.
