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?

Your mission:

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.

Your key responsibilities:

• 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.

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

• Strong experience with Python.

• Experience building backend systems capable of handling high load, ideally with FastAPI

• Practical experience designing, setting up, and deploying cloud architectures from scratch including monitoring and alerting, preferably in Google Cloud.

• Hands-on experience setting up CI/CD workflows, preferably GitHub Actions.

• Comfortable executing large scale refactoring and system modernisation.

• Solid testing skills and experience with automated testing practices.

• Fluency in English.

Nice to have:

• Experience with infrastructure as code, preferably Terraform.

• Experience with NoSQL databases, ideally Google Datastore.

• Experience with web development, with React or Next.js 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.
