iOS Mobile Developer, #1084iOS Engineer - On-Device Translation Platform | DHS/ICE Mission Environment
What You'll BuildA real-time speech translation app that runs entirely on-device: audio capture speech recognition translation text-to-speech, coordinated across multiple services on hardware-constrained iPhones. You'll integrate vendor-provided ML models, manage background OTA model delivery from AWS, build peer-to-peer device communication, and ship to production through a federal accreditation pipeline.
What You'll Own- The iOS application: architecture, performance, memory management, and production releases
- Integration of on-device ML inference frameworks (Core ML, ONNX Runtime, WhisperKit) - loading, lifecycle, error recovery - not training the models
- Real-time audio pipeline: AVAudioEngine, voice activity detection, buffer management at hardware-thread priority
- Background model delivery: resumable multi-file downloads over URLSession, state persistence, network transition handling
- Peer-to-peer transcript sharing between devices via MultipeerConnectivity
- Swift concurrency across all of the above without data races, deadlocks, or jetsam kills on 6GB devices
What You Bring- 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 - you'll have security and compliance teammates)
