We're hiring a senior iOS Swift engineer to join our team—focused on building our mobile app. I wrote this letter to help you decide if this is the right opportunity for you. In it, I share what you need to be successful, what success looks like, and challenges you're likely to face.

If it turns out this is a fit, I believe that you will be hard-pressed to find something more meaningful and impactful for your life and career.

It will take you time to read through, but if you do, you should learn something new, have a clear sense of what we're working on, and know if you'll thrive in our current environment. You won't find traditional requirements. Mostly because this isn't a traditional role and we're not looking for a traditional person.

For the right person, this could be a once-in-lifetime chance to do something that matters and propels your personal growth.

Thanks in advance for reading and sleep well,

Leon CTO and Co-founder @ Rise Science


What are we working on at Rise Science?

Humanity struggles with feeling good. Last year, 80% of the world spent $100B+ on caffeine alone. And people are turning to digital solutions to feel better. Last year there were 2.6B health and fitness app downloads. The problem is that most solutions are either complex new habits, like meditation or weight loss, or pricey tools designed for elites. This leaves most people without an easy, science backed way to feel better.

Ideally, anyone in the world should be able to pull out their phone and have all the guidance and feedback to feel your best.

Today, we’re the first app that uses sleep science to enhance energy. It has features to help you fall asleep and stay asleep like other sleep only apps, but Rise is the only app that uses data to offer energy feedback. Through our "sleep debt" metric and circadian rhythm analysis, we give actionable insights, based in nearly a century of academic sleep science. Today, we’re among the top 20 health apps globally, helping millions of people per year growing profitably. Apple’s also recognized our work with the Apple Design Award finalist in 2023 and the Editors Choice award.

We're building the first “energy” app built around your sleep.

Sleep is the most potent performance enhancing drug there is. It's the foundation of literally everything we can measure about you. And it's your nights that dictate your days.

You might ask “Does the world need another sleep app?” The answer is, no, it doesn’t. At least not a traditional one...

Through years of user research and product development, we learned that people don’t want to spend more time sleeping.

What people really want is to have more energy.
