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.

3. Team Building & Engineering Management
● Hire and grow a team of 5–8 engineers initially (scaling to 15–20).
● Establish engineering culture, values, and best practices.
● Build career frameworks, performance systems, and growth plans.
● Conduct 1:1s, mentor engineers, and drive continuous improvement.
● Set up processes for agile execution, deployments, and incident response.
4. Product & Cross-Functional Collaboration
● Work with the founder and product team on roadmap, feasibility, and prioritization.
● Translate product requirements into technical execution plans.
● Collaborate with design for UX quality and technical alignment.
● Support sales and customer success with integrations and technical discussions.
● Contribute technical inputs to product strategy and customer-facing initiatives.
5. Engineering Operations & Infrastructure
● Own CI/CD, testing frameworks, deployments, and automation.
● Create monitoring, logging, and alerting setups for reliability.
● Manage AWS infrastructure with a focus on cost and performance.
● Build internal tools, documentation, and developer workflows.
● Ensure enterprise-grade security, compliance, and reliability.
