About Wellth
Wellth is a pioneering digital health company that seeks to motivate and incentivize healthy habits through individualized care plans. Our approach draws on a unique combination of behavioral economics, habit science, and cutting-edge technology to drive positive behavior and habit change among some of the most underserved and high-needs patient populations in the US. Our work has produced demonstrable results, with several large health insurers reporting significant reductions in hospitalization rates, in some cases by up to 44%. Our ambition is to be more than just another digital health startup; we aspire to be a category leader in the $88B health outcomes market, singularly focused on improving the lives and medical outcomes of historically hard-to-engage populations. Our work has an immediate impact on people's lives every day, we have served over 30,000 patients, prevented an estimated 9,000 days in the hospital and 320 lives.

Role Description

As a Senior Mobile Engineer, you build important features in our React Native mobile application (Android and iOS) to motivate our members to achieve better health and earn their rewards. You operate with autonomy, taking user stories from our product team and turning them into well-tested mobile (and sometimes backend) TypeScript code that flows into our weekly staging releases and out to our internal dogfooding testers. When you find bugs or architecture inefficiencies, you create tasks to track them and work with our product and engineering leadership to prioritize those tasks against the rest of our backlog.

You thrive on the freedom and responsibility that comes with working at a growing startup. You take ownership of features from start to finish, and you collaborate well with our three other senior mobile engineers to build a high-quality and maintainable application.

You’ll report to our Director of Engineering, and you’ll work closely with our Product Managers, QA Analyst, and other engineers. We use an agile scrumban process, with 2-week sprints and daily standups.

Your work enables us to delight our tens of thousands of paid daily active users, to keep our 4.8+ star rating in the Apple App Store and 4.9+ star rating in the Google Play Store, and to help our health plan customers deliver millions of dollars of rewards to underserved populations and drive better health outcomes for the neediest patients in the healthcare system.

Our perfect hire has used gamification or behavioral economics techniques to build B2B2C healthcare mobile apps with React Native (and the APIs that serve them) used by hundreds of thousands of users or more in high-sensitivity environments. Don’t have all of that? That’s ok! We’ve been at this for many years now and can bring you up to speed quickly on any missing elements. Our team values openness and learning, with a focus on being excellent together for the sake of the health plan members that we serve.

This role is fully remote, with typically a few days of travel per quarter to meet with the team in-person in Los Angeles. Are you in LA and you want to spend more time in an office? We’ve got one in Playa Vista, and you can use it as much as you’d like! Our team has strong remote-first practices and tools and will continue that focus for the team while making a great gathering space available for our LA-local folks.
