Job description

Role Summary

Teceze is looking for an experienced native iOS Developer (Swift) to build and enhance field services mobile applications used by technicians on the move—often in low-connectivity environments and with high reliability requirements. You will own iOS features end-to-end (design → build → test → release), focusing on offline-first workflows, location services, scheduling/work orders, asset capture, secure data sync, and performance at scale.

Key Outcomes

• Field technicians can complete work orders reliably even with poor/no network (offline-first).
• App supports location-aware workflows (check-in/out, travel tracking, route support, geofencing as needed).
• Fast, stable, battery-efficient app with strong crash-free sessions and predictable performance.
• Secure handling of enterprise data with role-based access, encryption, and compliance-aligned practices.
• Continuous delivery via robust CI/CD, automated tests, and clean release discipline.

Responsibilities

Core iOS Engineering

• Build and maintain native iOS apps using Swift with UIKit and/or SwiftUI.
• Implement field service user flows such as:
• Scheduling & dispatch (daily jobs list, priority handling, SLAs)
• Job notes, checklists, parts/material usage, timesheets
• Barcode/QR scanning (assets/spares), optional NFC/BLE integrations
• Design and implement offline-first data layer:
• Local persistence (Core Data/SQLite/Realm as applicable)
• Background sync + conflict resolution strategies
• Queueing + retry mechanisms for failed uploads
• Integrate iOS app with backend services via REST/GraphQL, handle auth (OAuth2/JWT), secure token storage (Keychain).

Field Service / Mobility Capabilities

• job-site navigation support, arrival detection (where required)
• geotagging assets/photos, optional geofencing
• Support background tasks responsibly (battery/network constraints):
• Background fetch, BackgroundTasks framework, push-triggered refresh
• Optimize UX for real-world field conditions:
• fast loading, large touch targets, low-latency forms
• resilience to interruptions (calls, lock screen, app restarts)

Quality, Security & Delivery

• Write automated tests: XCTest, unit tests + UI tests; use mocking/stubbing for network/data layers.
• Monitor and improve quality using crash/performance tooling (e.g., Crashlytics/Sentry—based on Teceze stack).
• Ensure security best practices:
• Own App Store/Enterprise release readiness:
• Collaborate with Product, QA, Backend, and UX teams in Agile/Scrum delivery.

Required Skills & Experience

• 3–7+ years of native iOS development (Swift).
• Strong experience building field service / FSM / workforce mobility apps (or closely related):
• work orders, technician workflows, asset capture, offline mode, scheduling/dispatch
• Solid knowledge of iOS frameworks:
• Background execution constraints and best practices
• Experience with local data persistence and sync patterns:
• Core Data / SQLite / Realm; data modeling; migrations
• offline queueing and sync conflict resolution
• Strong debugging and performance optimization skills:
• Instruments, memory management, thread/concurrency control
