The Connectivity Software Team builds the critical link between WHOOP hardware, the iOS app, and the cloud. As an iOS Software Engineer on this team, you’ll design and implement the software that enables WHOOP’s wearable sensors to communicate seamlessly with the mobile platform. You’ll develop and optimize connectivity experiences that are robust, efficient, and invisible to the member — ensuring reliable data flow across our entire ecosystem.
RESPONSIBILITIES:
Architect, design, implement, and maintain iOS application components that interface directly with WHOOP hardware over Bluetooth Low Energy (BLE), Wi-Fi, or other communication protocols.
Define and evolve the iOS software architecture and communication protocols, maintain comprehensive documentation, and drive consistency across iOS and Android implementations.
Drive continuous improvement of performance, power efficiency, and reliability in the WHOOP connectivity software layer including background and system-level iOS services to enable reliable device connectivity, synchronization, and data transfer.
Champion strong software architectural principles for testable, scalable, maintainable software on your own team and across the organization.
Own and maintain a clear, prioritized backlog focused on code health, technical debt reduction, and testability improvements.
Raise the bar and champion higher engineering standards through prompt code review, increased test coverage, and improved design practices. Hold teammates accountable.
Represent the Connectivity iOS team in cross-functional settings such as bug triage, product syncs, firmware coordination, and guild representation.
Participate in the release process including getting the app built, managing build variants, signing, sending and testing through Firebase, and submitting to the App store
QUALIFICATIONS:
BS or MS in Computer Science, Electrical Engineering, or a related technical field, or equivalent experience.
5+ years of professional iOS software engineering experience with a solid foundation in Swift, iOS system APIs, concurrency, and memory management.
Hands-on experience with Combine and background task processing for non-UI iOS features.
Demonstrated examples influencing other engineers in the application of architectural and platform-based software design principals to build scalable, modular, testable software.
Experience debugging and diagnosing issues across complex or distributed systems (for example: firmware, mobile, backend) is a strong plus.
Excellent collaboration and communication skills, driving cross-functional problem solving, tradeoff definition, and optimization.
Strong commitment to embracing and leveraging AI tools in day-to-day tasks, ensuring AI-assisted work aligns with the same high-quality standards as personal contributions.
