- Use Claude or GitHub Copilot as a development accelerator, generating code scaffolding, writing and reviewing tests, creating documentation, and prototyping solutions;
- Own the engineering lifecycle for your features: architecture, implementation, testing, CI/CD, and production monitoring;
- Write clean, well-tested TypeScript code and maintain high standards through code review and documentation;
- Optimize application performance for speed, responsiveness, memory, and offline capability;
- Debug, troubleshoot, and resolve software defects and production issues;
- Participate in Agile or product-centric delivery practices including sprint planning and retrospectives;
- Learn and apply new technologies, tools, and patterns to improve system quality and team effectiveness.

MUST HAVES
- 4+ years of professional software engineering experience;
- Experience delivering production software;
- Experience working in Agile or team-based development environments;
- Experience developing software with JavaScript, Node.js, ReactJS, and React Native;
- Familiarity with REST APIs and service-based architectures;
- Experience working with databases and data persistence concepts;
- Ability to follow established architecture and development standards;
- Strong problem-solving and troubleshooting skills;
- Ability to collaborate effectively within an engineering team;
- Good communication skills and willingness to learn;
- Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience;
- Upper-intermediate English level.
