Principal Engineer

Job Summary

Key Responsibilities Architecture & System Design Define mobile architecture, coding standards, performance benchmarks, and best practices. Lead design of modular, clean, scalable architectures (MVVM, MVI, Clean Architecture, Redux, etc.). Own decisions around app structure, offline-first capabilities, caching, state management, and API integration. Work closely with backend and product teams to define system-level contracts (APIs, schemas, payloads). Mobile Engineering & Feature Ownership Lead development of complex, high-impact features end-to-end. Ensure smooth, fast, crash-free app performance across devices and OS versions. Optimize rendering, memory usage, storage, battery consumption, and network calls. Drive innovation around mobile UX, animations, interactions, and micro-frontends (if applicable). Scalability, Security & Reliability Implement advanced app security (secure storage, encryption, anti-tamper, SSL pinning). Build scalable architectures supporting millions of users with low latency. Define strategies for A/B testing, feature flags, rollout plans, and observability. Own release pipelines, CI/CD for mobile, and automated build & deployment tooling. Testing & Quality Establish mobile testing framework (unit, UI, snapshot, integration). Ensure automation coverage with tools like XCTest, Espresso, Appium, Detox, etc. Maintain high code quality with static analysis, linting, and automated checks. Tech Leadership & Mentoring Mentor senior engineers; provide technical direction across mobile teams. Conduct deep technical reviews for design documents, critical features, and releases. Drive engineering excellence—coding standards, performance budgets, documentation. Represent mobile engineering in cross-functional architectural discussions. Collaboration & Stakeholder Management Work closely with product, design, backend, QA, and DevOps teams. Influence roadmap decisions through strong technical judgment and data-driven insights.
