Sleep is something we all share. It's so fundamental that when we don’t get enough good-quality sleep, we struggle to function in all other aspects of life. That's why we at Sleep Cycle have made sleep improvement our mission, and that’s how you can help improve global health by joining our effort!
We’re now looking for an SDK Engineer to join our Platform team and help shape the future of our SDKs. This is your chance to bring our AI-powered sound technology to life, making it work reliably on millions of phones across the globe.
Interested in building robust SDKs that power our own products and are trusted by tech companies around the world? Do you enjoy designing stable APIs and tools? Excited to join a team where quality, reliability, and developer experience come first?
Your mission:
As an SDK Engineer, you’ll help transform advanced and sometimes highly complex technology, often close to the research frontier, into robust, well-designed, and easy-to-integrate products. You’ll play an important role in shaping how our technology reaches developers and users around the world.
You’ll take on a central role in a small, highly skilled technical team where your decisions truly matter. We work closely together, keep decision paths short, and share a genuine commitment to creating an exceptional SDK experience - both for ourselves and for the teams building on top of our platform.
This is an opportunity to work at the intersection of research and product, where you’ll get to turn advanced technology into something reliable, scalable, and used in the real world.
Your key responsibilities:
We encourage you to apply anyway - we value diverse perspectives and experiences and are committed to finding the right person, not just the perfect resume.
What’s in it for you?
Sleep Cycle is all about creating a supportive and stimulating work environment, surrounded by kind, talented teammates who genuinely enjoy working together. We believe in a healthy balance of focus and fun, where sharing a laugh together is just as important as delivering great work.
You’ll tackle interesting challenges and contribute to meaningful outcomes, all while collaborating in our beautiful office space on the 20th floor of the Kineum skyscraper in Gothenburg.
We look forward to your application!
