Mobile Software Engineer, Architecture & Core Platform

The Washington Post•Washington, DC

1d•$98,800 - $164,600•Onsite

About The Position

The Washington Post is seeking an experienced Mobile Software Engineer to drive the technical evolution of our flagship mobile applications. In this role, you will focus on core mobile architecture, application performance, modularity, and cross-cutting platform systems. Our native apps drive the majority of our digital reach and serve millions of daily readers, making app reliability, fluid responsiveness, and maintainable software design central to our engineering mission. You will be responsible for defining structural patterns, eliminating technical debt, optimizing foundation-level workflows (networking, caching, state orchestration), and safely integrating high-impact domain modules - ranging from reader experiences and personalization to native monetization frameworks.

Requirements

Design, implement, and maintain core mobile architecture patterns, shared foundational frameworks, and modular dependency graphs across the application.
Establish robust abstraction layers, adapter patterns, and dependency injection strategies to isolate high-risk third-party SDKs, revenue systems, and analytics vendors.
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.
Bachelorʼs 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.

Responsibilities

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.
