Job summary

Dev Technology seeks an iOS Engineer to develop a real-time on-device translation platform for a production-grade iPhone app. You will own architecture, performance, and releases while integrating on-device ML frameworks and ensuring robust AVAudioEngine pipelines.

The role requires 5+ years shipping iOS apps in Swift, expertise with ML integration frameworks, memory optimization, and secure, scalable networking on constrained devices. A federal-friendly environment is provided.

Qualifications

• 5+ years shipping production iOS apps in Swift.
• Direct experience with AVAudioEngine or AudioUnit at the hardware callback level.
• Track record integrating ML or signal-processing frameworks into iOS apps (Core ML, ONNX, TensorFlow Lite, or similar).
• Proficiency managing memory and performance on constrained devices using Instruments.
• Experience with background URLSession and resilient download/upload systems.
• Comfort with protocol-oriented architecture, multi-module Swift packages, and testable service layers.
• Ability to hold a clearance and work in a federal compliance environment (FISMA experience is a plus, not a requirement).

Responsibilities

• The iOS application: architecture, performance, memory management, and production releases.
• Integration of on-device ML inference frameworks—loading, lifecycle, error recovery—without training models.
• Real-time audio pipeline: AVAudioEngine, voice activity detection, buffer management at hardware-thread priority.
• Swift concurrency across all components to avoid data races, deadlocks, or jetsam kills on 6GB devices.
