Sr Mobile Engineer; IOS and Android - westminster

What You’ll Do:

• Design, build, and ship mobile features for device pairing, BLE connectivity, telemetry, health monitoring, and command/control — using AI (Claude Code) as a first‑class collaborator in your daily development workflow.
• Use agentic workflows to dramatically increase delivery velocity without sacrificing quality: from generating feature scaffolding, to writing and validating test coverage, to triage and root cause analysis during incidents.
• Collaborate with firmware, cloud, design, and product teams to define APIs, contracts, and end‑to‑end workflows — whether the feature is hardware‑driven or lives entirely in the app. – Build resilient experiences that handle messy real‑world conditions: flaky BLE, back grounding, battery constraints, intermittent connectivity, OS‑level lifecycle quirks, and the everyday performance bar of a high‑traffic consumer app.
• Own feature quality on your platform — iOS (Swift, Swift
  
  UI / RIBs, SPM) or Android (Kotlin, Jetpack Compose, Dagger, kokolib) or both Instrument features for observability, crash‑free sessions, and quality compliance; partner with the release team on Crashlytics triage.
• Write clean, testable, performant code; contribute to CI/CD automation and improve team‑wide engineering standards.

• 5+ years of experience shipping production iOS or Android applications at scale or both iOS: deep Swift, Combine/async‑await, Swift
  
  UI and/or UIKit, SPM, instrumentation; comfort with Core Bluetooth and background modes.
• Android: deep Kotlin, coroutines/Flow, Jetpack Compose, Dagger/Hilt, Gradle; comfort with Bluetooth/BLE APIs, foreground services, and Doze/standby behavior.
• Hands‑on experience prompting, evaluating, and building with LLMs — not just autocomplete, but as a genuine development partner.
• Deep experience with agentic workflows, prompt engineering, context window management, and MCP/function calling.
• A track record of using AI tooling to multiply your own output — faster specs, better test coverage, cleaner code, faster debugging.
• Strong experience with mobile architecture patterns, modularization, and dependency management at scale.
• Experience integrating with REST/gRPC backends, streaming/eventing, push notifications, and persistent local storage.
• Ability to collaborate across teams (firmware, cloud, design, product) and articulate technical tradeoffs clearly.

• Experience with BLE, IoT, telematics, wearables, or other hardware‑adjacent mobile work. Familiarity with high‑frequency event ingest, telemetry batching, or time‑series data on mobile.
• Background with mobile observability tooling (Firebase Crashlytics, Data Dog, Databricks, Amplitude).
• Experience with automated mobile testing frameworks (XCUITest, Espresso, Maestro, snapshot testing).
