Software Engineer III - Mobile

We have an exciting and rewarding opportunity for you to take your software engineering career to the next level.

As a Software Engineer III at JPMorgan Chase within the Consumer & Community Banking, you serve as a seasoned member of an agile team to design and deliver trusted market-leading technology products in a secure, stable, and scalable way.

You are responsible for carrying out critical technology solutions across multiple technical areas within various business functions in support of the firm's business objectives.

Job responsibilities


* Designs and delivers iOS software solutions by translating product requirements into scalable mobile architectures (e.g., MVC/MVVM/Clean), implementing features in Swift (UIKit/SwiftUI), and applying non-routine thinking to build elegant solutions and rapidly decompose complex technical issues through root-cause analysis, instrumentation, and debugging (Xcode, Instruments, crash logs).


* Builds secure, production-grade iOS code by writing high-quality, maintainable components and performance-conscious algorithms that integrate reliably with backend services and device capabilities, leveraging modern iOS concurrency patterns (GCD/Combine/async/await) to coordinate synchronous/asynchronous workflows, and enforcing mobile security best practices (secure storage/Keychain, data protection, least-privilege permissions, input validation).


* Produces iOS architecture and design artifacts for complex mobile applications by documenting end-to-end designs (module boundaries, data flow, navigation, state management, offline/online sync, API contracts) and maintaining accountability that design constraints (performance, accessibility, security, resilience, battery/network efficiency) are implemented and enforced in Swift code through reviews, standards, and automated checks.


* Gathers, analyzes, and synthesizes mobile and platform telemetry from large, diverse datasets (crash reports, performance traces, app analytics, network logs, CI/CD signals, feature-flag metrics, customer feedback) and develops clear visualizations/reporting (dashboards, release health summaries, regression trackers) to drive continuous improvement of iOS app quality and system reliability.


* Proactively uncovers hidden issues and patterns in iOS codebases and operational data (recurring crash signatures, memory leaks, ANRs/hangs, excessive network chatter, slow renders, flaky tests, dependency risk) and uses these insights to improve coding hygiene (refactoring, modularization, test coverage, linting, documentation) and evolve the app/system architecture (better layering, concurrency model, caching strategy, observability).


* Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, ...
