• Implement and manage complex business logic and service orchestration using advanced Python libraries like NumPy, SciPy and frameworks like  FastAPI.
• Build and integrate high-throughput data processing and automation scripts, leveraging expertise in Lua scripting for specific low-latency or embedded tasks (e.g., within game engines, databases, or web servers like Nginx/OpenResty).
• Ensure seamless data persistence and retrieval by designing and optimizing interactions with both relational (PostgreSQL, MySQL) and NoSQL MongoDB databases.
• Apply system-level performance optimization techniques, focusing on efficient memory management, concurrency models, and minimizing I/O bottlenecks in both Python and Lua environments.
• Implement robust security practices, including data encryption, secure API endpoints, and appropriate authentication/authorization protocols.

• Collaborate in Agile/Scrum teams, participating in sprint planning, code reviews, and daily stand-ups.
• Manage source code using Git-based workflows (branching, merging, pull requests) with GitLab and Bitbucket CI/CD pipelines.
•  Write and maintain comprehensive unit tests and integration tests using standard Python frameworks like Pytest, unittest, and Mock to ensure code quality.

What you’ll need

• 6+ years of proven experience in backend development, system architecture, and high-performance programming using libraries SciPy & NumPy.

• Hands-on expertise in Python and its core ecosystem, including frameworks like Django, Flask, or FastAPI.
• Understanding of Lua scripting for specialized tasks such as performance-critical logic, embedded systems, or extending server capabilities (e.g., Nginx/OpenResty).
• Experience with RESTful API design and implementation, as well as working with real-time data using protocols like WebSockets.
• Practical knowledge of Git-based version control workflows and continuous integration/continuous deployment (CI/CD pipelines).
• Strong debugging and performance optimization skills for both Python services and database queries.
• Experience in writing and maintaining comprehensive unit tests and integration tests using Pytest, unit test, and Mock.
• Solid understanding of Agile methodologies and experience contributing to microservices architecture.

Added Advantage (Good to Have)

• Exposure to Lua scripting language.
• Familiarity with containerization technologies like Docker and orchestration tools like Kubernetes
