Back End Developer

Are you passionate about building leading-edge products with clean, well-tested, secure code? The Resilient Group is looking for a Senior Developer with expertise in Java. Reporting to the VP of Technology, you will have the opportunity to own key business components and build them from scratch in an agile development environment. You will also play an integral role within a team by providing high quality technical deliverables. We would like you to work closely with designers, product managers, and other stakeholders to define and execute on our vision and strategies. This is a great opportunity to work with a forward-thinking company on exciting new projects.

About the Project

We’re building an open-source, non-custodial platform for communication and storage that puts control back in the hands of users. Instead of relying on centralized services that own, monetize, or restrict access to data, our platform is designed so individuals retain full ownership of their identity, messages, and files by default.

What you will be doing

• Design and implement scalable, distributed proxy and relay servers
• Develop backend message dispatching and storage services
• Build APIs and backend services consumed by iOS and Android applications
• Implement storage integration with Ceph and / or AWS S3
• Design and implement a central monitoring server where all nodes report :
• Health status
• Metrics
• Server activity and events
• Develop REST APIs and a web-based admin interface for monitoring and management
• Ensure systems are secure, fault-tolerant, and highly available
• Collaborate on system architecture, performance tuning, and scalability planning
• Participate in code reviews and maintain clean, well-documented code
