Senior Flutter Mobile Engineer (Wearables)

Type: Full-time

Location: Remote

HLTH is one of the fastest growing brands of 2026, reaching the top 3% in growth of all stores in the Shopify ecosystem and we’re just getting started (literally). At HLTH we believe understanding your health should be effortless. Our devices and app turn health monitoring into clear insights anyone can act on. We build for people who care about longevity, balance, and a healthier future because healthcare shouldn't be reactive. It should be proactive, continuous, and deeply personal.

HLTH is an intense environment: we’re demanding and ambitious, which means we ask a lot of ourselves and one another. This means fantastic learning, achievements, and career growth, but it also requires a significant commitment. We move fast, standards are high, and ownership is real. This is not a coast job. If you want to be challenged, stretched, and pushed harder than ever before, we invite you to apply.

We are building the future of continuous health optimization at HLTH. Our biometric wearable lives or dies on the reliability of its data pipeline. We aren't looking for a traditional app developer who just hooks up UI views to REST endpoints. We need a Senior Flutter Mobile Engineer who specializes in Flutter to own it end to end: ensuring our app seamlessly wakes up, reconnects, restores state, and processes critical health data over low-power BLE streams without draining the user's device.
