About Us

Sunnyside is the #1 platform for mindful drinking. Nearly one in three US adults are categorized as excessive drinkers, yet fewer than 1% get help to improve their drinking habits. We know why. There's a huge gap in the alcohol health market for the millions of consumers who enjoy drinking and have no desire to quit entirely, yet could nonetheless benefit from building a healthier relationship with alcohol. Sunnyside fills this gap with a digital therapeutic proven to help anyone who regularly drinks improve their overall health and wellness by changing their relationship with alcohol. We take a differentiated approach by focusing on moderation and mindfulness rather than complete sobriety, providing a much-needed alternative for the millions of adults looking to cut back.

We've got a rapidly growing base of highly engaged paying customers, a vibrant member community, best-in-class engagement and strong retention. And we're just getting started. Just as Calm built a billion dollar business by opening a new popular wellness category around proactive mental health, we'll do the same for alcohol-related wellness. We're well funded by top investors including Uncork Capital, Adjacent VC, Nir Eyal, Mike Lee (founder of MyFitnessPal), and James Park (founder of Fitbit) We're perfectly positioned to establish ourselves as the category leader in the growing mindful drinking space. Help us make it happen.

About the role

We're looking for a generalist full-stack software engineer to help us take our product experience to the next level, and to support our growing base of members. You'll build new features end-to-end, and be an owner of key business logic and systems spanning from database and backend app logic, to web and iOS. After the first few months, you will also be expected to share Pagerduty rotation and be on-call. This a unique opportunity to get involved in the early stages with a fast-growing company, while having a positive impact on a huge group of people. It’s going to be a fun ride.

About our stack

We are a Typescript shop. We use react-native for iOS, NextJS+MaterialUI+React for web frontend, and NestJS for all backend, using typeorm on mysql, redis, and mongodb. We host everything on AWS ElasticBeanstalk and EC2, RDS for DB, Elasticache for redis, and SQS for our job queue.

About you

You are scrappy and entrepreneurial, with a get sh** done attitude. You thrive in ambiguity and love pushing the boundaries of what's technically possible, without losing sight of the practical need to move quickly and ship quality code. You're excited to work heads-down to do whatever it takes to get new features out the door, with an ownership mindset. You should want to tell us what we should build next, vs. expecting someone to simply dictate tasks to you.

Startup experience is not required, but an understanding of what may be required, especially during the early days, is necessary. This is going to be a fast-paced, exciting, fulfilling role which could grow into something huge.

We're a mission-driven company with a passion for this space, and are looking to build a team that can build deep empathy for our users and is genuinely excited about the problem we're solving.


These are some of the potential projects you will build and own:

  • Member community, multiplayer features, social graph, social sharing
  • User insights dashboard, charts and 3rd party data integrations
  • Messaging and notifications logic
  • User administration, authentication, payments
  • Recommendation algorithms
  • AI coaching layer
