We're looking for a skilled and passionate
Senior iOS Developer
to join our team and build mobile applications. This role will serve as the subject matter expert on iOS development at Wavelynx. You'll be responsible for the full app development lifecycle, from concept and design to testing and deployment. A successful candidate will have a keen eye for detail, a passion for clean code, experience with Bluetooth protocols (CoreBluetooth/GATT), some backend experience (Python, PostgreSQL, FastAPI) & a dedication to creating high-quality, user-friendly applications with strong observability and reliability. Bonus points if you're familiar with the Google Cloud Platform (e.g., Cloud Run, Pub/Sub, Secret Manager). A strong passion for UI/UX and design systems is a
huge
plus.
Responsibilities
Design, build, and maintain high-performance, reusable, and reliable iOS applications using Swift, Xcode, Swift Concurrency, and Swift Package Manager. Collaborate with cross-functional teams, including product managers and other engineers, to define, design, and ship new features on existing applications and SDKs; occasionally implement and maintain related backend services in Python/Flask with Postgres. Ensure the performance, quality, security, and responsiveness of applications and services; instrument apps with logging/metrics/crash reporting. Identify and remediate bottlenecks and defects; drive continuous performance tuning for app startup, BLE I/O, networking, and rendering. Integrate with and maintain backend services & first-party APIs using REST, handle auth flows, and secure storage (Keychain/CryptoKit). Help maintain code quality, organization, and automation via code review, and CI/CD (Fastlane/TestFlight/App Store Connect). Stay up-to-date with new iOS technologies, trends, and best practices (SwiftUI/Combine) and advocate for accessibility and privacy-by-design. Assist with release management, code signing, and App Store deployment; maintain internal and public SDK packages. Partner closely with design on UI/UX flows, accessibility, and adherence to Apple's HIG; contribute to design system components where appropriate. Qualifications
Proven experience as an iOS Developer with a portfolio of shipped apps (App Store or enterprise/TestFlight) and/or SDKs. Excellent problem-solving, analytical, and communication skills; ownership mindset and collaborative approach. Proficiency in Swift; familiarity with Objective-C interop and Python/Flask for service endpoints is a plus. Deep understanding of iOS SDKs and Apple's design/interface guidelines; experience with UIKit and working knowledge of SwiftUI/Combine. Hands-on experience with CoreBluetooth (central/peripheral, GATT services/characteristics) and robust BLE error handling; CoreNFC experience is a plus. Experience with data persistence (Core Data or alternatives), background tasks, and offline-first patterns. Solid grasp of mobile app architecture (MVC/MVVM/MVU) and modularization using Swift packages. Proficiency with Git and modern CI/CD tooling (e.g., Fastlane, Xcode Cloud, or GitLab/GitHub Actions). Comfort with RESTful API integration, JSON encoding/decoding, and networking stacks (URLSession); understanding of auth, Keychain, and CryptoKit. Experience with testing (XCTest, unit/UI tests, mocks) and debugging with Instruments (time profiler, allocations, energy). Demonstrated UI/UX sensibility and accessibility awareness; experience collaborating with designers and contributing to design systems is a plus. GCP familiarity (App Engine, Cloud Run, Pub/Sub, Secret Manager, Cloud Storage) is a plus. Bachelor's degree in Computer Science, Software Engineering, or related field, or equivalent practical experience Salary and Benefits
The salary range for this position is offered at $130-150k Along with our salary, we offer great rates on company-sponsored medical, dental, and vision insurance with HSA-eligible plans available, generous retirement with up to a 6% 401(k) match, as well as holidays, vacation, and sick leave.
