Tech Lead Manager - React Native

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.

We are looking for a hands‑on Tech Lead Manager to lead the engineering efforts for building cross‑platform experiences as we realize the vision of a fully connected care platform. You will partner closely with Product, Design, Hardware, and business leaders to iterate and deliver on context‑rich workflows that improve the caregiver experience so they can focus on providing quality care to their residents.

As an engineering leader on the Product Engineering team, you will set the foundation of our native strategy and collaborate with other engineers to build hardware + software solutions. Success in this role requires close attention to details, creative problem‑solving, and a strong bias toward action and experimentation.

• Define the native application strategy, evaluating candidate hybrid architectures through hands‑on proof‑of‑concept work and delivering a clear, written recommendation with tradeoffs the team can act on.
• Develop the first iteration of our mobile native app, both prototyping and building a production‑ready version of our core platform.
• Establish the integration boundary between our existing web application and the native layer, ensuring web engineers can continue to ship features without being blocked by native build complexity.
• Own the end‑to‑end native build, release, and over‑the‑air update pipeline, from local development through app store submission and production delivery.
• Drive the implementation of native device capabilities — including device identification, configurable push notifications, and Bluetooth Low Energy interactions with IoT hardware — that are out of reach from the browser today.
• Partner with Platform Engineering to ensure the backend infrastructure supports reliable, at‑scale delivery of push notifications to Sage‑managed devices.
• Build and grow a small, high‑performing native engineering team, including hiring, mentoring, and developing engineers while defining the practices and tooling that keep the team moving quickly.
• Collaborate closely with Product, Design, Hardware, and business leaders to translate user and hardware needs into a coherent native product experience.
• Contribute hands‑on to architecture decisions and early‑stage implementation, setting technical standards and serving as the go‑to resource when the team hits hard native platform problems.

• 8+ years of software engineering experience, with at least 3 years leading engineering teams or projects.
• Experience shipping a production native Android application to Google Play — you have personally navigated the full release pipeline, not just the code.
• Hands‑on experience with at least one hybrid native framework (React Native, Ionic + Capacitor
  
  JS, Flutter + Dart, etc.) and a clear point of view on when hybrid is the right call versus full native.
• Experience integrating device APIs from a hybrid runtime — such as device identity, push notification delivery, or Bluetooth Low Energy peripheral interaction — not just reading documentation about them.
• Experience managing or mentoring engineers, including setting technical direction and conducting…
