📋 Description

• About us: Syndica supplies the most critical applications in Web3 with enterprise-grade RPC infrastructure and developer tools tailored for the Solana ecosystem. • About you: You're an experienced iOS engineer who thrives in high-impact environments where architecture, performance, and user experience are critical. You’ve built and scaled mobile applications for large user bases and know how to make them fast, reliable, and sleek. • Standout Experience: Led architecture or re-architecture of a high-scale, user-facing mobile app. Worked in fast-paced, product-driven environments like Stripe, Coinbase, or Robinhood. Familiarity with Web3 technologies, Solana wallets, or cryptographic integrations on mobile. • About the role: As a Senior iOS Engineer, you’ll take ownership of designing and delivering performant, scalable, and sleek mobile features for our Web3-powered tools and apps. You’ll work closely with design and backend teams to build a seamless user experience for developers and end users alike. • Key responsibilities: Architect and implement high-quality iOS features with an emphasis on performance and scalability. Own mobile performance, from launch time and memory usage to smooth interactions and responsiveness. Define and maintain patterns and frameworks to keep the codebase scalable and efficient. Integrate with REST/GraphQL APIs and implement robust data handling, including offline support and caching. Collaborate with designers to deliver pixel-perfect, platform-native UI. Contribute to developer tooling, CI/CD pipelines, testing strategies, and documentation. Drive best practices across the engineering team. • What does success in this role look like?: In three months, you’ve led the implementation of core features, contributed to architectural decisions, and driven improvements in performance and code quality. In six months, you’ve led a major performance upgrade or refactor, contributed to product planning, and established iOS best practices. In twelve months, you’ve helped define the long-term vision for our mobile platform, led large-scale architecture initiatives, and ensured the app scales with our growing user base.
