Tech Lead Manager - React Native

Sage • New York, NY

6h • $190,000 - $245,000 • Hybrid

About The Position

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.
About this Role
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.

Requirements

• 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 + CapacitorJS, 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 code review at an architectural level.
• Experience partnering closely with Product and Design leaders to shape product strategy and user-centered solutions.
• Track record of building experimentation-driven development processes and rapid MVP iteration cycles.

Nice To Haves

• Comfortable working across the full stack; able to collaborate with backend engineers on notification infrastructure and device management APIs without needing hand-holding on the contracts.
• Experience managing native application deployment pipelines end-to-end: versioning strategies, build automation, code signing, app store submission, and over-the-air update delivery.
• Experience building or operating a high-reliability push notification pipeline — device token lifecycle, delivery guarantees, and handling of silent vs. visible notifications.
• Experience with Bluetooth Low Energy — scanning, pairing, service/characteristic discovery, connection state management — in a production application on real hardware.
• Experience deploying and managing native applications through a mobile device management (MDM) platform, including app provisioning, configuration policy enforcement, and managing OS and app updates on enrolled device fleets.
• Experience with programmatic audio control on mobile: routing audio output, managing platform audio sessions, and handling system-level interruptions.
• Prior experience in a startup, incubation, or 0-to-1 environment where architectural decisions had long-lasting consequences.

Responsibilities

• 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.

Benefits

• Our benefits package for employees includes competitive base compensation along with stock options.
• 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.
• We also have a take as you need time off policy, in addition to 7 paid holidays and a company wide winter break during the holidays.
