* Build reliable job queues for long-running tasks such as AI processing, video processing, notifications, and other automated workflows.

* Integrate third-party APIs, webhooks, payment gateways, and external services.

* Develop backend infrastructure for multi-user SaaS applications.

* Work with large file and video-processing workflows where required.

* Build APIs and services that communicate with AI/ML and video-processing workers.

* Write clean, maintainable, modular, and well-documented code.

* Write unit and integration tests using **Pytest**.

* Participate in code reviews and maintain development standards using Git.

* Work closely with **AI/ML engineers, frontend developers, Flutter developers, DevOps engineers, and QA engineers**.

* Troubleshoot and resolve production issues.

* Help design the technical architecture as the products scale.

## Preferred Candidate Profile

* 3+ years of professional backend development experience.

* Strong knowledge of **Python**.

* Strong experience with **FastAPI**, Django, or similar backend frameworks.

* Strong understanding of REST APIs and backend architecture.

* Good knowledge of **PostgreSQL and SQL**.

* Experience with **Redis** and asynchronous processing.

* Experience with **Celery, RabbitMQ, Kafka, or similar queue systems**.

* Good understanding of authentication, authorization, JWT, OAuth, and API security.

* Experience with Docker and Linux.

* Strong Git/GitHub or GitLab experience.

* Experience building and integrating third-party APIs and webhooks.

* Understanding of database optimization, indexing, transactions, and query optimization.

* Experience writing automated tests with Pytest or similar frameworks.

* Understanding of cloud platforms such as AWS, Azure, or Google Cloud.

* Ability to design modular and scalable backend systems.

* Strong debugging and problem-solving abilities.

* Good communication and teamwork skills.

## Perks & Benefits

* **Competitive salary** based on skills and experience.

* **6-day working week**.

* **Paid overtime** for additional working hours.

* Clear compensation for extra work beyond regular working hours.

* Healthy and professional **work-life balance**.

* Friendly, respectful, and collaborative working environment.

* Opportunity to work on **real-world AI, SaaS, automation, and marketplace products**.

* Opportunity to work with modern technologies including **Python, FastAPI, PostgreSQL, Redis, Docker, AI/ML, cloud infrastructure, and video-processing systems**.

* Opportunity to take ownership of major technical components of the products.

* Career growth opportunities as the company and engineering team expand.
