Platform Engineer

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 Platform Engineer to join our Infrastructure team for the next chapter of our journey.

Do you enjoy solving deep technical challenges with real impact? Do you thrive in a role where you can both build and improve large-scale systems? Do you want to enable product teams to move fast by giving them solid, reliable infrastructure to build on?

As a Platform Engineer in our Infrastructure team, you'll develop, build and maintain the internal products, services, and platforms that power Sleep Cycle. You'll ensure our systems stay robust, scalable, and secure. You enable product teams to focus on delivering exceptional user experiences.

You'll work across backend systems, cloud infrastructure, internal tools, and build/release processes, taking on both modernisation work and greenfield initiatives.

Develop and maintain high quality backend systems in Python built for scale and performance.

Develop and support internal web based systems used by teams across the organisation.

Design, deploy, and operate cloud architectures from the ground up including monitoring and observability.

Own data transformation tasks such as migrations, restructuring, and integrations.

Improve and evolve our build and release processes including CI/CD pipelines.

Contribute to major technical initiatives such as system replacements, refactoring, and modernisation of legacy services.

Collaborate closely with other developers to ensure shared systems remain healthy, secure, and reliable.

Write well tested, maintainable, and high quality code.

Bachelor's degree in Computer Science, Software Engineering, or related field, or equivalent practical experience.

3+ years of professional software development experience

Strong experience with Python.

Experience with web development, with React or as a plus.

Experience with native mobile development including Swift for iOS or Kotlin for Android.

Familiarity with data engineering workflows.

Experience supporting and facilitating team development.

Experience with RESTful API's.

You are humble, curious, and highly motivated.
You enjoy variation in your work including backend systems, internal tools, infrastructure, and release processes.
You're self driven, take initiative, and are not afraid of large technical challenges.
You care deeply about software architecture and delivering high quality solutions.
You enjoy collaborating with others and thrive in an environment where improving things is part of everyone's responsibility.

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.

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.
