- Comfortable with GitHub for version control and deployments
- Exposure to manual and/or automated testing
- Experience with performance tuning, debugging, and production issue resolution
- Prior experience working with remote or cross-border teams
- Comfortable with working on legacy code, boring technology or research on bleeding edge stack
Responsibilities
- Design, build, and maintain end-to-end web and mobile features, from database to UI
- Refactor and improve existing systems to enhance performance and reliability
- Write clean, readable, and maintainable code following best practices
- Ensure cross-browser and cross-device compatibility
- Develop and maintain reusable components and shared libraries
- Identify bottlenecks and implement performance optimisations across the stack
- Collaborate closely with designers, product managers, and other developers
- Take ownership of tasks and proactively suggest improvements to systems and processes
- Contribute to technical discussions and help raise overall code quality
Other Information
- You will be working with a Singaporean team, and also with other colleagues from Indonesia as we scale up our development team.
- Candidates must be comfortable in communicating in English (spoken and written) & able to collaborate effectively with Singapore-based stakeholders and Indonesian-based teammates
