Resumo da oferta

PT. Trimegah Sekuritas Indonesia, Tbk is seeking an experienced Android developer to own the architecture, quality, and performance of our Android app.

You will build core flows such as order entry, portfolio, watchlist, and onboarding while handling real-time market data with WebSocket lifecycle management. The role emphasizes client‑side order integrity, security features like certificate pinning and biometric authentication, and strong observability.

Qualificações

• 5+ years of Android development experience with senior-level responsibility.
• Proficient in Kotlin and Jetpack Compose.
• Strong understanding of modern concurrency with Kotlin Coroutines.
• Experience with MVVM / Clean Architecture and modularization.
• Ability to justify technical decisions to non‑technical stakeholders.

Responsabilidades

• Own the architecture, quality, and performance of the Android app end to end.
• Build and maintain core flows: order entry, portfolio, watchlist, transaction history, onboarding.
• Handle real-time market data on the client — WebSocket lifecycle, reconnect strategy, snapshot + delta.
• Protect order integrity client-side: client order IDs, deduplication, idempotency, and state handling when network drops.
• Demonstrate security: certificate pinning, biometric authentication, jailbreak detection, sensitive-screen protection.
• Improve observability: crash‑free rate, latency metrics, and response actions.
• Advance the Android CI/CD pipeline: automated builds, signing, TestFlight, faster release cycles.
• Apply release discipline: feature flags, staged rollout, reliable rollbacks, and non‑exchange hour releases.
• Review code, mentor engineers, and set mobile engineering standards.
• Collaborate with compliance, risk, and security from the design stage.

Descrição da oferta de emprego

• Own the architecture, quality, and performance of the Android app end to end
• Build and maintain core flows: order entry, portfolio, watchlist, transaction history, onboarding
• Handle real-time market data on the client — WebSocket lifecycle, reconnect strategy, snapshot + delta, conflation for slow connections, and keeping the UI smooth while thousands of instruments tick
• Protect order integrity client-side: client order IDs, deduplication, idempotency, and correct order state machine handling when the network drops mid-submit
• Financial-grade app security: certificate pinning, Keychain storage, biometric authentication, jailbreak detection, sensitive-screen protection
• Honest mobile observability: crash‑free rate, hang rate, cold start, per‑endpoint latency — and acting on the numbers
• Mature the Android CI/CD pipeline: automated builds, signing, TestFlight, shortening commit‑to‑release time
• Release discipline: feature flags, staged rollout, genuinely tested rollback, and releasing outside exchange hours
• Review code, mentor engineers, and set the mobile team's engineering standards
• Work with compliance, risk, and security from the design stage rather than as a rubber stamp at the end

Minimum Qualifications

• 5+ years of Android development, including at least 2 years carrying senior‑level technical responsibility
• Deep Kotlin; comfortable in Jetpack Compose
• Modern concurrency: Kotlin Coroutines, Combine or equivalent
• Architecture at scale: MVVM / Clean Architecture, modularization, dependency injection — and the reasoning behind the choice
• Networking: URLSession, WebSockets, caching, graceful behaviour on poor connections
• Testing: unit, snapshot, and UI tests, with a clear point of view on what is worth testing
• Performance and memory profiling with Instruments
• Android CI/CD: Bitrise, or GitHub Actions
• Able to explain technical decisions to non‑technical stakeholders — in this industry you will do it often
