Software Engineer III - Mobile

About the role

As a seasoned member of an agile team within Consumer & Community Banking at JPMorgan Chase, you will design and deliver trusted, market-leading iOS technology products in a secure, stable, and scalable way. This role involves carrying out critical technology solutions across multiple technical areas to support the firm's business objectives.

Responsibilities

• Design and deliver 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 decompose complex technical issues through root-cause analysis, instrumentation, and debugging (Xcode, Instruments, crash logs).
• Build secure, production-grade iOS code by writing high-quality, maintainable components and performance-conscious algorithms that integrate with backend services and device capabilities. Leverage modern iOS concurrency patterns (GCD/Combine/async/await) and enforce mobile security best practices (secure storage/Keychain, data protection, least-privilege permissions, input validation).
• Produce iOS architecture and design artifacts for complex mobile applications, documenting end-to-end designs (module boundaries, data flow, navigation, state management, offline/online sync, API contracts). Ensure design constraints (performance, accessibility, security, resilience, battery/network efficiency) are implemented and enforced through reviews, standards, and automated checks.
• Gather, analyze, and synthesize mobile and platform telemetry from large, diverse datasets (crash reports, performance traces, app analytics, network logs, CI/CD signals, feature-flag metrics, customer feedback). Develop clear visualizations and reporting (dashboards, release health summaries, regression trackers) to drive continuous improvement of iOS app quality and system reliability.
• Proactively uncover 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). Use insights to improve coding hygiene (refactoring, modularization, test coverage, linting, documentation) and evolve app/system architecture (better layering, concurrency model, caching strategy, observability).
• Leverage enterprise-authorized AI coding assist tools to improve code quality, delivery speed, and productivity (e.g., code generation/refactoring, unit test creation, documentation). Validate outputs through peer review, automated testing, and secure coding standards, and contribute reusable patterns to improve team effectiveness.
• Apply knowledge of tools within the Software Development Life Cycle toolchain, including AI-assisted development and automation capabilities, to enhance the value realized by automation.

Requirements

• Formal training or certification on software engineering concepts and 3+ years of applied experience.
• Hands-on experience designing iOS/mobile systems end-to-end, including application development in Swift (UIKit/SwiftUI), unit/UI testing (XCTest/XCUITest), and ensuring operational stability through monitoring, crash triage, performance tuning, and production support.
• Proven ability to develop, debug, and maintain code in a large enterprise environment using modern languages (Swift) and data/querying technologies relevant to mobile workflows (e.g., SQL fundamentals, REST/GraphQL usage and troubleshooting, log/metric querying via observability tools).
• Strong working knowledge of the Software Development Life Cycle, with an emphasis on mobile release management (App Store/TestFlight, phased rollouts, feature flags).
• Solid understanding of Agile delivery practices, including CI/CD for iOS (build pipelines, automated tests, code quality gates), application resiliency (graceful degradation, offline support, retries/backoff, crash-free sessions), and mobile security (secure storage/Keychain, encryption in transit/at rest, OWASP MASVS concepts, privacy and permission handling).
• Hands-on experience using enterprise-authorized AI-assisted software development tools (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security.
• Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations. Ability to guide peers on safe and effective usage within team practices.

Preferred Qualifications

• Familiarity with modern front-end technologies and patterns that interface with mobile clients (e.g., component-based UI concepts, TypeScript/React basics, webviews, design systems) and the ability to collaborate effectively with web and design teams.
• Exposure to cloud technologies used by mobile ecosystems, such as API gateways, authentication/identity (OAuth2/OIDC), serverless/event-driven backends, storage/CDNs, and mobile observability/analytics platforms. Comfort diagnosing issues across client–backend boundaries.
• Familiarity with Objective-C.
