Gothenburg, Västra Götaland, Sweden Sleep Cycle Full time 60,000 - 120,000 per year

Make a real difference in improving global health at a highly product-driven company with a true start-up mentality. Join Sleep Cycle as a Mobile Developer and build state-of-the-art, AI-powered features for the world's No.1 Sleep App.

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 how you can help improve global health by joining our effort

We're now looking for a Mobile Developer to join our team for the next chapter of our journey.

Do you enjoy building products that make a meaningful impact on people's lives? Are you a curious problem-solver who thrives in collaborative teams? Do you get excited by the idea of creating and shipping features that help people sleep better?

Your mission:

As a Mobile Developer at Sleep Cycle, you'll work in a cross-functional team that practices continuous discovery and owns outcomes, not just output. You'll help shape hypotheses, run experiments, and frequently deliver user value through small, impactful feature improvements.

Your key responsibilities:

  • Design, build, test, and maintain high-quality code for our mobile app.
  • Collaborate closely with your team to define and implement user-facing features.
  • Contribute across the stack where it's appropriate, with support to grow beyond your primary focus area.
  • Participate in code reviews, technical design discussions, and contribute to continuous improvement.
  • Write well-tested, secure, and scalable software.
  • Monitor performance and troubleshoot production issues in a shared ownership model.
  • Work with ML Engineers and Research Scientists to understand model behavior and how it integrates into the app experience.

What we are looking for:

  • Bachelor's degree in Computer Science, Software Engineering, or related field, or equivalent practical experience.
  • 3+ years of professional software development experience, with solid experience in at least one native mobile platform (iOS or Android).
  • Comfortable working with at least one part of our stack: Swift, SwiftUI, Kotlin, Jetpack Compose (plus some legacy Objective-C/Java)
  • Familiarity with modern Git-based workflows, CI/CD, and testing.
  • Fluency in English.

Nice to have:

  • Backend experience with Python, FastAPI, and Google Cloud (e.g., Datastore, Cloud Storage, BigQuery).
  • Willingness to learn and contribute across the stack.
  • Interest in product thinking and delivering customer value.
  • Experience collaborating in product-driven teams or interest in learning how.
  • Demonstrated adaptability, accountability, and initiative in dynamic or evolving product environments.
  • Experience supporting and facilitating team development.

Not sure if you meet every requirement?

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
