(HQ) Sr. Frontend Engineer

The Senior Frontend Engineer designs and builds our SPA platform on a modern monorepo with micro-frontend architecture. Beyond shipping features, this role contributes to architectural decisions, maintains a high-quality bar through reviews and standards, and drives AI-augmented development practices to scale team productivity.

About Our Team:
•    We use Github Enterprise for our version control tool, so we have Pull Request/Tag/Feature Branch in our develop flow.
•    Jira is our issue tracking platform, and we also use confluence for documentation.
•    We use Jenkins Pipeline for CI flow, and Ansible is our CD tool for deployment.
•    Our system architecture is based on AWS, and we use lots of AWS Service in our system flow and platform.
•    We love to share our technical knowledge and domain know-how.
•    Everyone is open mind and you don’t have to be hesitated to ask any question.
