About the role

About Us

At TechBiz Global, we are providing recruitment service to our TOP clients from our portfolio. We are currently looking for a Business Development Executive to join one of our clients' team. If you're looking for an exciting opportunity to grow in a innovative environment, this could be the perfect fit for you.

The Role

We are looking for a Senior iOS Developer to build a companion app from the ground up. This product is an AI-powered, privacy-first workspace that integrates with enterprise tools through a unified intelligent layer.

The iOS app will bring this experience to iPhone and iPad, offering users an always-on assistant that prioritizes data security and sovereignty.

Responsibilities

  • Take full ownership of the iOS stack — including architecture, UI/UX, networking, on-device ML inference, and App Store delivery.
  • Define the technical direction and set the standards the team will follow long-term.

Requirements

  • 5+ years building production iOS apps in Swift; strong SwiftUI and UIKit fluency
  • Shipped at least one app with on-device ML (Core ML, ONNX runtime, or equivalent)
  • Deep familiarity with iOS security APIs (Keychain, Data Protection, Secure Enclave, App Attest)
  • Experience building offline-first apps with robust sync and conflict resolution
  • Comfortable with CI/CD for mobile (Fastlane / Xcode Cloud), TestFlight distribution, and App Store review processes
  • Strong product design sense - experience in app design, with a keen eye for craft, motion, and the details that make an app feel native

Nice to Have

  • Experience with RAG pipelines, vector databases, or AI-agent architectures
  • Published open-source Swift packages or technical writing on iOS architecture
  • WatchOS or visionOS prototyping experience

What You'll Build

  • Native SwiftUI interface for Fluso’s conversational AI, task management, and knowledge-graph views
  • On-device inference pipeline for privacy-sensitive operations (local embeddings, summarization, PII redaction)
  • Deep integrations with system frameworks - WidgetKit, Siri Shortcuts, Spotlight indexing, push notifications, App Intents
  • Real-time sync engine with the Fluso backend (WebSocket + incremental REST), handling offline-first conflict resolution
  • Secure credential storage and end-to-end encrypted channel for connected accounts (Gmail, Calendar, Slack, Drive)
  • Multi-window iPad experience with stage manager support and keyboard-first workflows
