iOS Developer (Swift / Mobile Edge Architecture)

At Domesly, we are pioneering real-time, active voice-coaching technology for high-performance cyclists. While legacy tools focus on pre-ride planning (TrainingPeaks, Zwift) or post-ride post-mortems (Strava, Intervals.icu), Domesly acts as an active digital Directeur Sportif while the rider is pedaling.

By pairing live sensor telemetry (Bluetooth power meters, HR monitors, cadence) with real-time edge AI models and open-ear bone conduction audio hardware, we deliver instantaneous voice directives (pacing, W balance threshold protection, interval timing) directly to the rider without taking their eyes off the road or blocking ambient traffic noise.

The Opportunity: iOS Developer

We are seeking a hands-on, high-velocity iOS Developer to build, own, and scale the native iOS mobile experience for Domesly at our Vizag hub.

In this role, you will lead the client-side architecture—focusing on native iOS CoreBluetooth integrations, real-time audio pipeline management, low-latency UI updates, and seamless bridging with our high-performance Rust core telemetry engine. Working side-by-side with our systems engineering team, you will help scale our tech stack from a working prototype to global mass commercialization.

Key Responsibilities

• Native iOS App Architecture: Architect, build, and maintain our high-performance iOS application using modern Swift and SwiftUI/UIKit, ensuring fluid performance, minimal battery draw, and sub-150ms UI response times during live rides.
• Rust Core & FFI Integration: Partner with our Rust team to bridge native C-ABI/UniFFI Rust libraries into the iOS app, enabling real-time telemetry processing, local caching, and offline-first calculations on-device.
• Bluetooth & Peripheral Management: Implement robust, production-grade CoreBluetooth flows to manage multi-sensor connections simultaneously (power meters, heart rate monitors, cadence sensors, and smart trainers) with aggressive auto-reconnection and zero data loss.
• Low-Latency Audio & Background Execution: Build background-safe audio processing pipelines (AVFoundation) to stream context-aware voice directives to bone-conduction headsets, ensuring reliable execution even when the screen is locked or competing with background navigation/music apps.
• Third-Party Ecosystem Integrations: Integrate two-way sync APIs and SDKs for leading sports and training platforms (HealthKit, Strava, Garmin Connect, Wahoo, TrainingPeaks, Intervals.icu, Zwift).
• Engineering Best Practices (Vizag Hub): Establish best-in-class iOS development standards, automated XCTest/XCUITest suites, memory leak monitoring (Instruments), CI/CD pipelines (TestFlight / App Store Connect), and OTA update handling.

What We Are Looking For

• Experience: 3+ years of professional native iOS development experience shipping consumer-facing or hardware-connected App Store products.

Core Tech Stack Proficiency

• Deep expertise in Swift, Combine, and Async/Await concurrency models.
• Advanced mastery of iOS system frameworks: CoreBluetooth, AVFoundation, CoreLocation, HealthKit, and background processing modes.
• Demonstrated experience interfacing native Swift code with low-level C libraries or Rust foreign function interfaces (FFI / UniFFI / CXX).
• Solid understanding of offline storage (CoreData, SwiftData, or SQLite) and REST/GraphQL/WebSocket API consumption.
  

Telemetry & Performance Optimization

• Hands-on experience optimizing iOS battery life, background thread management, and real-time data streaming under resource constraints.
• Experience profiling apps using Xcode Instruments (Memory Leaks, Time Profiler, Energy Impact).

Domain Passion

• High affinity for sports technology, wearables, or endurance sports (cycling, running, triathlon).
• Being a cyclist who understands power meters, FTP, normalized power, and training metrics is a big plus!

Location

• Based in or willing to relocate to Visakhapatnam (Vizag) to work directly with our core R&D team.
