Job Description

We're hiring a

Senior Mobile Engineer

to build production ready mobile apps and services that integrate with

Meta's Glasses SDK for Ray-Ban Meta smart glasses

. This role is at the cutting edge of mobile, real-time audio/video, Bluetooth/Wi-Fi transport, and multimodal AI designing

hands-free, voice-first, vision enabled experiences

spanning the glasses, a companion mobile app, and cloud AI.

What You'll Do

Own end-to-end development of a companion mobile app that interfaces with Ray-Ban Meta smart glasses via Meta's Glasses SDK. Implement reliable

camera and audio streaming pipelines

with strict attention to latency, battery efficiency, and privacy (camera LED, permissions). Build

voice-first UX flows

: wakeword detection, push-to-talk, VAD/ASR/TTS, earcons, and low-latency audio playback on open-ear speakers. Integrate

on-device ML (Core ML, MediaPipe, ONNX Runtime, NNAPI)

with cloud based multimodal AI (e.g.,

Llama 3 vision/voice

) via streaming APIs. Manage

transport/connectivity

: Bluetooth LE control channels, Wi-Fi/Wi-Fi Direct media streaming, reconnect logic, pairing flows, and session lifecycle state machines. Design resilient pipelines with

observability, retries, offline fallback, and graceful degradation

under thermal, bandwidth, or permissions constraints. Collaborate with product/design to invent new

voice-first interaction patterns

; run user tests; track metrics (latency, accuracy, task completion). Establish

mobile CI/CD pipelines

, automated testing (unit/integration/device-in-the-loop), crash/error analytics, and release processes. Champion

privacy-by-design

and ensure compliance with platform and bystander safety policies.

Minimum Qualifications

5+ years

professional mobile engineering experience, shipping

native apps at scale

on iOS or Android (both strongly preferred)

. Deep proficiency in:

iOS:

Swift, SwiftUI/UIKit, AVFoundation, CoreBluetooth, CoreMotion, background modes, concurrency (GCD/Async/Await), audio units.

Android:

Kotlin, Jetpack Compose/Views, Bluetooth/BLE, Camera/Media, Foreground Services, Coroutines/Flow.

Strong experience with

real-time media pipelines

(audio/video capture/playback, echo cancellation, noise suppression, lip-sync, latency budgeting). Networking and systems skills:

state machines, threading, buffering, backpressure, power/thermal profiling

, and debugging on constrained devices. Experience integrating

cloud AI services

(LLM/ASR/TTS) and handling streaming inference results in the mobile UI. Product sense for

voice-first UX

and accessibility in eyes-up, hands-free contexts. Strong communication skills; comfortable with

early SDKs

and evolving requirements.

Preferred Qualifications

Experience with

Meta's Glasses SDK (Ray-Ban Meta)

or similar wearables (Apple Watch/visionOS audio, Snap Spectacles, Bose Frames). On-device ML expertise: Core ML, Metal, Accelerate (iOS), MediaPipe, TFLite, NNAPI, GPU delegates (Android), ONNX Runtime Mobile. Multimodal AI integration: Llama-family models, Whisper/Seamless/ASR, TTS providers, streaming inference UX.

BLE expertise

: GATT design, throughput tuning, Wi-Fi coexistence, provisioning, firmware update flows.

WebRTC

for low-latency A/V: adaptive bitrate, jitter buffers, AEC/VAD tuning. Backend familiarity (Python/Node.js): inference gateways (FastAPI/Express), WebSocket servers, token streaming. Deploying model servers (Triton, vLLM), vector/RAG stacks (FAISS/Pinecone), observability (OpenTelemetry), autoscaling (AWS/GCP/Azure). Security & privacy: keychain/keystore, secure BLE pairing, PII handling, consent UX, regional data controls. Hardware-in-the-loop QA: automated tests for glasses events (connect, capture, LED state, battery, IMU), performance tests for end-to-end latency.
