About the Role

We’re looking for a Python Backend Developer to design, develop, and maintain scalable backend systems that power our web and mobile products.

You’ll be responsible for crafting robust APIs, optimizing database operations, and ensuring the security, performance, and reliability of production systems. This role demands a strong understanding of backend architecture, hands-on coding ability, and the discipline to build for the long term.

You’ll collaborate closely with frontend developers, designers, and product managers to align backend functionality with product goals and deliver seamless user experiences.

Key Responsibilities

• Design, build, and maintain scalable, secure, and modular backend systems using Python (Django, FastAPI, or Flask).
• Develop and document RESTful APIs and ensure smooth integration with web and mobile clients.
• Optimize database performance, queries, and schema design for PostgreSQL/MySQL.
• Integrate third-party APIs and external services (payments, notifications, authentication, etc.).
• Implement authentication, authorization, and data security using JWT, OAuth, or session-based methods.
• Handle asynchronous processing with Celery, Redis, or message brokers like Kafka.
• Implement caching, rate limiting, and API performance tuning for large-scale systems.
• Deploy, monitor, and maintain applications on Linux-based servers and cloud environments (AWS preferred).
• Write and maintain unit/integration tests using Pytest or Django Test Framework.
• Collaborate with the frontend and design teams for smooth API integration and version management.
• Participate in code reviews, documentation, and continuous improvement cycles.

Requirements

• 6 months – 3 years of professional experience in backend development using Python.
• Strong experience with Django / FastAPI / Flask, ORM handling, and REST API design.
• Proficient with PostgreSQL / MySQL, migrations, indexing, and query optimization.
• Solid understanding of authentication, authorization, and API security standards.
• Experience with Redis, Celery, and background task orchestration.
• Familiar with Docker, Git, and deployment via Nginx + Gunicorn / Uvicorn.
• Skilled in API testing tools (Postman, Insomnia) and debugging workflows.
• Familiarity with frontend integration concepts (React / HTML / JS).
• Strong Linux command-line and server management skills — SSH, SCP, rsync, bash scripting.
• Understanding of real-time communication (WebSockets, long polling) and async I/O patterns.

Preferred Skills

• Experience setting up CI/CD pipelines (GitHub Actions / GitLab CI).
• Familiarity with AWS, GCP, or Azure deployment environments.
• Experience integrating payment gateways, SMS/email APIs, or healthcare integrations.
• Knowledge of data encryption, MFA, and secure API authentication (Google / Apple Sign-In).
• Experience with transactional email systems (SMTP).
• Understanding of rate limiting, load testing, and backend profiling (Locust, k6, JMeter).
• Exposure to asynchronous frameworks like FastAPI for high-performance APIs.

What You’ll Get

• Work on real, production-grade systems that scale and evolve.
• Collaborate with a highly technical, growth-focused team.
• Build solutions across AI, data systems, and cloud infrastructures.
• Access to learning-driven mentorship and career growth opportunities.
• Competitive compensation aligned with skill and technical impact.
