Description:
We are seeking a talented Python Developer with specialized experience in the SMPP (Short Message Peer-to-Peer) protocol to join our dynamic team. The ideal candidate should possess a strong background in SMS messaging, extensive experience with the python-smpp library, and familiarity with JSMPP (Java SMPP). You will be responsible for developing and maintaining the backend of our messaging platform, ensuring high performance, scalability, and reliability.
Responsibilities:
- Craft and implement the architecture for the backend of our messaging platform, focusing on modularity, scalability, and maintainability.
- Integrate and manage SMS gateways using SMPP and JSMPP.
- Write clean, efficient, and well-documented Python code to develop backend services and utilize the python-smpp library to handle SMPP protocol operations, ensuring robust message handling.
- Develop unit tests and perform thorough testing of the backend components to ensure reliability and performance and debug and resolve any issues that arise during development and testing phases.
- Establish and manage SMPP connections to various SMS gateways.
- Implement logic for sending and receiving SMS messages through SMPP connections and ensure that messages are correctly formatted, encoded, and decoded according to SMPP specifications.
- Develop robust error handling mechanisms to manage issues such as message delivery failures, connection timeouts, and protocol errors. Implement retry logic and fallback strategies to ensure high message delivery success rates.
- Design and implement solutions to scale the messaging platform to handle increasing volumes of SMS traffic.
- Conduct load testing and performance benchmarking to identify bottlenecks and optimize system performance and use tools and techniques to simulate high traffic scenarios and ensure the platform can handle peak loads.
- Monitor and manage system resources, such as CPU, memory, and network bandwidth, to ensure efficient utilization and prevent resource exhaustion.
- Investigate and diagnose issues related to SMPP connections, message delivery, and backend performance and use logging, monitoring, and debugging tools to identify root causes and implement fixes.
- Respond to incidents and outages promptly, working to restore service and minimize downtime and conduct post-incident analysis to identify improvements and prevent recurrence.
- Proactively identify areas for improvement in the backend systems and SMPP integrations. Implement enhancements and optimizations to improve reliability, performance, and maintainability.
Requirements:
- Proficiency in Python programming.
- Strong understanding of the SMPP protocol and experience with SMPP client and server implementations.
- Utilize JSMPP (Java SMPP) for additional integration and functionality.
- Expertise in HTML, CSS, JavaScript
- Experience with RESTful APIs and web services.
- Proficiency in JSMPP (Java SMPP) and its applications in SMS messaging.
- Spring Framework (Spring Boot, Spring MVC, Spring Security, Spring Data)
- Familiarity with message queuing systems and databases (e.g., RabbitMQ, Redis, MySQL).
- Excellent problem-solving skills and the ability to troubleshoot complex issues related to messaging systems.
- Hands on experience with Object-Oriented Programming (OOP) concepts
- Proficiency with Data Types, Variables, and Operators
- Strong verbal and written communication skills, with the ability to explain technical concepts to non-technical stakeholders.
- Ability to work effectively in a collaborative team environment.
- In-depth knowledge of SMS messaging protocols and standards.
- Experience with cloud platforms (e.g., AWS, Google Cloud) and containerization (e.g., Docker, Kubernetes).
- Understanding of security best practices in messaging systems.
- Experience working in an Agile development environment.
- Must have strong knowledge in python smpp library and twisted framework.
Qualification:
A bachelor's degree in computer science, Software Engineering or a related field.
Experience:
Minimum of 2 years of professional experience in SMS messaging with Python, specifically using the python-smpp library.
