Senior iOS Engineer to build polished, performant, and reliable user-facing features in a fitness app, collaborating with product and design teams remotely.
About the company
- We are Playbook, a leading creator platform for fitness, health, and wellness. Our mission is to help fitness creators build sustainable businesses, while enabling hundreds of thousands of users to live healthier lives.
- We are a fast-growing company in the fitness tech space, operating as a remote-first, product-driven team that values ownership, direct communication, and a strong growth mindset. We believe in “drivers, not passengers” — everyone is encouraged to take responsibility, think proactively, and act like an owner.
Responsibilities
- Design and implement new iOS features with a strong focus on usability, clarity, and delivering value to real users.
- Build and maintain robust, scalable mobile architecture (including networking, data persistence, and state management) that supports fast iteration and long-term maintainability.
- Work closely with Product Managers and Designers to translate requirements into practical, well-scoped technical solutions. Provide input during planning to ensure features are feasible, maintainable, and aligned with user and business goals.
- Ensure high-quality releases through clean, readable, and well-tested code. Participate in code reviews and contribute to shared standards around quality, testing, and maintainability.
- Take ownership of the features you build. Identify issues or gaps, propose improvements, and iterate based on feedback. You’re comfortable working with ambiguity and adapting as requirements evolve.
- Improve app performance and reliability by diagnosing bottlenecks, addressing crashes, and strengthening overall stability and user experience.
Requirements
- 5+ years of professional software development experience, with a strong focus on iOS development. Proven experience shipping production iOS applications end-to-end.
- Strong proficiency in Swift and modern iOS development practices. Ability to build responsive, user-friendly interfaces with attention to detail and performance.
- Experience with modern iOS UI patterns, including handling complex navigation, animations, and edge cases in real-world production apps.
- Active daily use of AI coding assistants (Claude Code, Codex, OpenCode, or similar) for development, debugging, and problem-solving. We expect engineers to leverage these tools to ship faster and work through complex problems.
- Strong understanding of networking on iOS (REST/GraphQL), including authentication flows, caching strategies, error handling, and offline/unstable network scenarios.
- Experience designing maintainable architectures (e.g. MVVM, Redux-style state management, Clean Architecture, or similar) and improving existing codebases over time.
- Solid understanding of iOS performance and debugging tools (e.g. Instruments, crash reporting, profiling) and the ability to diagnose issues effectively.
- Strong communication skills in English. Comfortable working in a remote, cross-timezone team and collaborating asynchronously.
Nice to have
- Experience with other frontend or mobile technologies, such as React Native or React.js, and an interest in cross-platform product development.
- Experience with SwiftUI in production and building scalable design systems.
- Experience integrating and maintaining third-party SDKs (analytics, payments, video, attribution).
- Experience implementing and maintaining subscription flows on iOS
- Familiarity with CI/CD for iOS (Fastlane, GitHub Actions, Bitrise, or similar) and improving developer velocity.
- Experience working in a startup or fast-growing product company .
Conditions
- Your work will directly affect creators and users on the platform. You’ll work on features that ship quickly and matter.
- Competitive B2B salary with equity options.
- 100% remote with flexible working hours and async-friendly culture. Collaboration across Europe and the US East Coast.
- A collaborative team that values ownership, open communication, and autonomy over micromanagement.
- Yearly team retreats focused on connection, alignment, and building strong team relationships.
- Paid Time Off
Other
- We’re looking for a Senior iOS Engineer to join our remote engineering team. You’ll work on meaningful, user-facing product features in our iOS app — building polished, performant, and reliable experiences that our users and creators rely on every day.
- You’ll collaborate closely with Product and Design to deliver solutions aligned with real customer needs. This role is best suited for a senior individual contributor who enjoys hands-on development, product problem-solving, and working in a fast-moving startup environment.
