The role involves modernizing and evolving the existing mobile ecosystem, establishing scalable architectural patterns, and ensuring the platform can support continued product and business growth.\n\nExperience with e-commerce platforms, product catalogs, or other high-traffic consumer-facing applications will be highly valuable.\n\nKey Responsibilities\n\nDefine, evolve, and own the overall mobile platform architecture.\n\nLead large-scale mobile modernization, re-architecture, and platform evolution initiatives.\n\nEstablish and scale standards for mobile application architecture, engineering practices, testing, and release management.\n\nContribute directly to production mobile code and develop proofs of concept for new architectural approaches.\n\nDrive architecture reviews and technical decision-making across multiple engineering teams.\n\nEstablish mobile platform governance, architectural standards, and reusable engineering patterns.\n\nIdentify and address performance, scalability, reliability, and maintainability challenges across mobile applications.\n\nPartner with Product, Backend, Platform, Data, Security, and Infrastructure teams to ensure architectural alignment.\n\nMentor senior engineers and raise engineering quality through architecture reviews, code reviews, and technical guidance.\n\nDocument and scale architectural decisions, best practices, and organizational learnings.\n\nTechnical Requirements\n\n12+ years of software engineering experience, including significant experience at Staff, Principal, Architect, or equivalent level.\n\nExperience with cross-platform technology: React Native.\n\nExpertise in Swift/iOS and Kotlin/Android development will be a plus.\n\nDeep understanding of modern mobile architecture patterns, modular application design, and platform architecture.\n\nProven experience leading mobile modernization or re-architecture initiatives.\n\nStrong knowledge of mobile performance optimization and application scalability.\n\nExperience designing offline-first mobile applications and data synchronization strategies.\n\nStrong knowledge of mobile CI/CD, testing practices, release engineering, and automation.\n\nStrong engineering fundamentals across code quality, automated testing, observability, reliability, and continuous delivery.\n\nExperience designing and evolving large-scale distributed systems, including APIs, event-driven architectures, data pipelines, and high-scale platforms.\n\nExperience with e-commerce platforms, product catalogs, or high-traffic consumer applications.\n\nTechnical Leadership\n\nProven ability to drive cross-team and cross-organizational technical decisions and platform initiatives.\n\nExperience aligning multiple engineering teams around architecture, standards, and technical direction.\n\nAbility to evaluate architectural trade-offs and drive decisions through implementation.\n\nStrong experience conducting architecture and code reviews and mentoring senior engineers.\n\nAbility to influence technical and business stakeholders without formal authority.\n\nStrong communication skills and experience working across Product, Data, Security, Infrastructure, and Engineering organizations.\n\nExperience collaborating with globally distributed teams, including teams across the US, LATAM, and Asia.\n\nAI-Assisted Engineering\n\nHands-on experience using modern AI-assisted development tools, such as GitHub Copilot, Claude Code, Cursor, or similar tools, in production engineering workflows.\n\nExperience defining or implementing AI-driven SDLC practices, including engineering standards, automation patterns, and appropriate guardrails.\n\nAbility to demonstrate how AI-assisted development has improved engineering workflows while maintaining code quality, security, and reliability.\n\nWhat We’re Looking For\n\nThe ideal candidate is not only an architect but also a hands-on Principal-level engineer who is comfortable moving between strategic architecture decisions and production code.\n\nYou should be able to define the technical direction of a mobile platform, align multiple engineering teams around it, and help turn architectural decisions into scalable, production-ready solutions.\n\nAvailability to collaborate during Pacific Time Zone (PT) working hours is required.","description_format":"text","description_chars":5076,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
