Mobile Software Engineer, Architecture & Core Platform

• You are passionate about clean system design, modular codebases, and establishing design standards that make multi-team feature development faster and safer.
• You care deeply about fundamental app metrics-cold start times, smooth 60/120 fps rendering, battery efficiency, and low memory footprints.
• You enjoy solving systemic, cross-cutting engineering problems that impact the entire application stack, not just isolated user interfaces.
• You appreciate that third-party systems and revenue mechanisms are integral to running a premier media operation, and you relish the challenge of isolating external dependencies behind strict, testable abstractions.
• You are eager to work with modern native patterns (Swift, Kotlin, declarative UI) and explore shared architecture paradigms to streamline cross-platform capabilities.

How You’ll Support the Mission

• Design, implement, and maintain core mobile architecture patterns, shared foundational frameworks, and modular dependency graphs across the application.
• Drive app-wide technical initiatives: optimize cold/warm startup times, reduce memory and binary footprint, and eliminate main-thread bottlenecks using profiling tools.
• Establish robust abstraction layers, adapter patterns, and dependency injection strategies to isolate high-risk third-party SDKs, revenue systems, and analytics vendors.
• Partner with product, backend, and feature teams to establish standardized API contracts, networking patterns, data persistence schemes, and caching strategies.
• Lead architectural design discussions, author RFCs, define code quality benchmarks, and conduct thorough peer code reviews.
• Support high-impact vertical integrations (such as native monetization, audio/video playback, and content feeds) by designing clean hook points and lifecycle management pipelines.
• Ensure app compliance with platform privacy policies, sandbox requirements, and operating system updates across Apple and Google ecosystems.
• Champion automated testing standards, CI/CD pipeline reliability, and contract testing across client-server boundaries., * Design, implement, and maintain core mobile architecture patterns, shared foundational frameworks, and modular dependency graphs across the application.

• Lead architectural design discussions, author RFCs, define code quality benchmarks, and conduct thorough peer code reviews.
• Champion automated testing standards, CI/CD pipeline reliability, and contract testing across client-server boundaries.

• Bachelor’s degree in Computer Science, engineering, a related technical field, or equivalent practical experience.
• 3+ years of professional mobile engineering experience shipping large-scale, production-grade applications.
• Strong proficiency in modern native mobile development (Swift/iOS; familiarity with Android or Kotlin Multiplatform is a strong asset).
• Deep understanding of architectural paradigms (MVVM, Clean Architecture, Unidirectional Data Flow / MVI, modularization) and design patterns.
• Proven track record diagnosing and resolving system-level performance issues (concurrency, memory leaks, frame drops, network overhead).
• Experience architecting SDK integration layers, wrapper libraries, or plugin systems that protect host app stability and crash-free rates.
• Solid grasp of client-server API design, schema definition (REST, Protocol Buffers/gRPC, or GraphQL), and offline-first data synchronization.
• Demonstrated commitment to code hygiene, automated testing (unit, integration, snapshot/UI), and continuous integration workflows.

Collaboration makes us stronger. That’s why our offices are designed with open layouts, modern technology, and easy access to transportation. With certain exceptions for newsgathering and business travel, we work on-site five days a week.
