• Good logical and problem solving skills
• Clear communication skills
• Never give up attitude
• Passionate to learn and acquire new skills

Our current technology stack includes Android, Python, Flask, MongoDB, RabbitMQ, ElasticSearch and AWS. While it is a bonus to have worked on the same set of above listed technologies, it is not a must until you have hands-on experience with similar technologies.

To give you an idea about what you will be working on after joining us, you will be

• Dockerizing different services and automating our AWS infrastructure provisioning steps
• Optimising our backend services to scale for a few hundreds of concurrent users
• Managing our backed service and adding new features to it
• Working on refactoring our current android codebase to a cleaner design
• Mentoring junior developers
