- Follow and help improve frontend engineering standards, coding practices, and quality benchmarks within the team.

- Build and integrate AI workflows into the product and development process, including LLM-powered features, AI-assisted tooling, and agentic automation.

- Contribute to performance optimisation efforts, including rendering strategies, caching, bundling and code-splitting, asset optimisation, and runtime monitoring.

- Make sound technical decisions related to data-fetching patterns, state management, SSR/CSR strategies, routing, and application modularity within your areas of ownership.

- Collaborate with backend teams on API contracts and ensure efficient communication between the client and server layers.

- Mentor SDE1 and SDE2 engineers through code reviews, pairing sessions, and design discussions.

- Participate in engineering initiatives such as refactors, migrations, performance improvements, and reliability enhancements.

- Help maintain frontend observability, including logging, monitoring, performance profiling, error tracking, and analytics, to improve stability and user experience.

- Troubleshoot and resolve production issues, performance bottlenecks, rendering inconsistencies, and browser-specific problems, contributing to root-cause analysis and durable fixes.

- Write robust tests, including unit tests, integration tests, and end-to-end automation, to ensure reliability and safe deployments.

- Contribute to developer experience improvements through tooling, build pipeline optimisation, automation, and documentation.

- Stay current with emerging frontend technologies and AI tooling, and propose relevant improvements to product performance and developer productivity.
