performance across CloudSEK products.\nFollow and help improve frontend engineering standards, coding practices, and quality benchmarks within the team.\nBuild and integrate AI workflows into the product and development process, including LLM-powered features, AI-assisted tooling, and agentic automation.\nContribute to performance optimisation efforts, including rendering strategies, caching, bundling and code-splitting, asset optimisation, and runtime monitoring.\nMake sound technical decisions related to data-fetching patterns, state management, SSR/CSR strategies, routing, and application modularity within your areas of ownership.\nCollaborate with backend teams on API contracts and ensure efficient communication between the client and server layers.\nMentor SDE1 and SDE2 engineers through code reviews, pairing sessions, and design discussions.\nParticipate in engineering initiatives such as refactors, migrations, performance improvements, and reliability enhancements.\nHelp maintain frontend observability, including logging, monitoring, performance profiling, error tracking, and analytics, to improve stability and user experience.\nTroubleshoot and resolve production issues, performance bottlenecks, rendering inconsistencies, and browser-specific problems, contributing to root-cause analysis and durable fixes.\nWrite robust tests, including unit tests, integration tests, and end-to-end automation, to ensure reliability and safe deployments.\nContribute to developer experience improvements through tooling, build pipeline optimisation, automation, and documentation.\nStay current with emerging frontend technologies and AI tooling, and propose relevant improvements to product performance and developer productivity.\n\nRequirements:
