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.
