The role
We're looking for a Technical Lead to drive the bot's technical development, guide open-source community contributors, and ensure the project's quality, security, and stability.

- Mentor contributors with constructive, actionable feedback
Active development
- Implement critical features and fix priority bugs
- Maintain and improve order flows, disputes, and community modules
- Ensure code complies with linting, tests, and documentation
Project management
- Daily issue triage: categorize, reproduce bugs, maintain a clear roadmap
- Manage releases: changelogs, versioning, build verification
- Keep dependencies updated (Telegraf, mongoose, lightning, etc.)
Security and operations
- Audit hold-invoice logic, Mongo queries, admin commands
- Monitor background jobs, respond to incidents, document lessons learned
- Coordinate with admins/solvers in dispute or abuse cases
