Collaborate closely with Product, QA, DevOps, and other engineering teams in a matrix environment while executing independently.
Improve engineering standards and code quality through reviews, mentoring, and technical guidance, especially around frontend testing and maintainability.
Troubleshoot complex production issues, perform root-cause analysis, and deliver long-term, robust fixes.
Participate in estimations, planning, and technical decision-making, and influence the product roadmap through engineering insights.
