Senior Full Stack Engineer - TalkingYak

Talking Yak is an Android-based English teaching system made specifically for native Hindi and Tamil speakers.

Our program includes over 400 intelligently-structured videos, thousands of exercises, over 10,000 vocabulary words and phrases, and a system that adapts itself to each learner. In a matter of months, we can elevate most learners to a 100% functional English capability.

We are one team at TalkingYak consisting of honest, moral & ethical individuals who are heard and valued! We hold ourselves accountable- delivering on expectations & celebrating each other for the great work we do!

We’re looking for a senior developer who has a lot of passion towards solving real world problems using technology. 

Below are some of the developer qualities we like a lot,

• Good team player
• Ability to write clean readable code
• 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

While we feel a developer with 4 to 8 years of hands-on experience will be more suitable for this role, it shouldn't be a hard constraint if you have the required skills.

We would love to get in touch immediately and have a conversation, if you feel our interests align.
