Job summary

TekRek in Toronto is hiring a mobile-focused engineer to own the native iOS and Android experience end to end, from feature development through release. This is a hands-on build role for someone who wants direct ownership of a live consumer product, is comfortable shipping fast, and doesn't mind stepping into backend, DevOps, or data work when a feature calls for it.

Strong candidates are equally comfortable in Swift or Kotlin and can operate independently across the release pipeline.

Qualifications

Proven experience shipping native mobile apps, with deep expertise in either Swift/SwiftUI or Kotlin/Compose.
Strong grasp of mobile architecture, state management, and performance profiling.
Working knowledge of relational databases, schema design, and migrations.
Some backend exposure; comfort picking up a modern server-side language is valued.

Responsibilities

Build and ship new features across native iOS and Android apps used by a large, fast-growing audience.
Own the mobile release process from testing through app store submission and rollout.
Deliver polished UI with real-time data and animation, tuned for performance.
Partner with backend engineers on API design and real-time data streams when mobile features need it.
Work across CI/CD, analytics instrumentation, and production monitoring to keep the app fast and stable.
