Job description

iOS Mobile Developer, #1084

 

iOS Engineer — On-Device Translation Platform | DHS/ICE Mission Environment

What You'll Build

A 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)

 

The estimated salary range for this position is $100,000 - $160,000. This salary range is not a guarantee of compensation. The offered salary will be based on factors including relevant experience, geographic location, internal equity, and applicable contractual requirements. *Compensation may fall outside this range when appropriate.
