English Only OK! Sr Java Developer (Professional dispatch)

求人詳細

Joining as a Senior Engineer, a hands-on leader who delivers through execution. Your primary output is high-quality software: design documents, production code, and reliable deployments.
In addition, you will play a key role in improving overall team quality by bridging the gap between experienced engineers and the broader team. You will connect architectural intent with day-to-day implementation; staying close enough to the system design to guide direction, and close enough to the code to ensure correct execution.

【Responsibilities】
Design & Development
- Lead basic design for new features and PSP integrations, including: Software architecture, Component design, Database schema design
- Establish and maintain clear design guidelines and coding standards
- Develop, test, and deploy production-grade Java applications end-to-end

Review & Quality Improvement
- Review system designs before implementation to identify structural issues early
- Conduct code reviews focusing on correctness, maintainability, and security
- Provide clear, actionable feedback that explains the reasoning (“why”), enabling team learning
- Identify recurring issues and convert them into documented guidelines to prevent repetition

Team Enablement
- Support engineers and team leads by aligning design intent with implementation
- Act as a bridge between leadership and engineers to improve consistency and reduce friction
- Raise the overall engineering standard through hands-on guidance and example
