Own the operational health of the new platform. Implement the right alerting and monitoring to ensure you always have a pulse on performance. Define SLA/SLO definitions with business and team, and work to create transparency and observability on those metrics.
Build content ingestion and management systems to help automate content updates & dissemination while building tools for a feedback loop on content accuracy.
Work closely with stakeholders (e.g. product and design teams) to define system requirements, weighing engineering and product tradeoffs to recommend technical options that are extensible, scalable, robust, secure, and maintainable.
Lead design and implementation of complex technical systems, estimating scope of work, organizing and prioritizing work, communicating timelines, managing expectations, and providing timely status updates.
Be responsible for the quality of code you ship, troubleshooting complex issues and driving them to resolution. Own and be accountable for the business-critical systems you deliver.
Mentor junior engineers and promote the success of the team by participating in design reviews, providing critical code review feedback, assisting and unblocking team members, contributing to and supporting team values and processes.
