We are looking for an experienced Python Engineer with strong software engineering fundamentals and a passion for building scalable, reliable, and intelligent applications. The role involves developing production-grade Python services, designing robust application architectures, integrating internal and external systems, and building AI-enabled product experiences. The ideal candidate should be comfortable working across application logic, backend integrations, asynchronous workflows, and production infrastructure. This is a product engineering role that requires strong coding skills, sound system-design judgment, and the ability to investigate and resolve real-world production issues. Requirements Key Responsibilities - Backend Development: Build and maintain production-ready Python services that power real-time applications and AI-enabled product experiences. - Application Architecture: Design modular and maintainable software architectures with clear separation between business logic, workflows, integrations, and infrastructure. - Asynchronous Programming: Implement asynchronous and event-driven workflows that effectively handle concurrency, timeouts, cancellations, retries, and partial failures. - API Development and Integration: Integrate internal and external systems through well-designed APIs, streaming interfaces, message queues, and structured data contracts. - Production Reliability: Ensure application quality and reliability through effective logging, monitoring, metrics, distributed tracing, automated testing, and safe release practices. - Troubleshooting and Debugging: Investigate production issues, analyse runtime evidence, identify root causes, and implement long-term solutions to prevent recurring failures. - Technical Design: Translate product requirements into practical technical designs, balancing scalability, maintainability, and simplicity. - Cross-Functional Collaboration: Work closely with Product, Frontend, Platform, Data, and Customer-facing teams throughout the design, development, and deployment lifecycle. - Code Quality and Engineering Practices: Participate in code reviews, maintain technical documentation, and continuously improve development processes and engineering workflows. Required Skills and Qualifications - 5+ years of professional software development experience with strong hands-on expertise in Python. - Strong understanding of object-oriented programming, functional design principles, and software engineering best practices. - Experience with Python typing, packaging, dependency management, and maintainable code structures. - Practical knowledge of asynchronous programming, concurrency, API design, and distributed system failure scenarios. - Experience developing and managing backend services using relational or document databases, caching mechanisms, and messaging systems. - Strong understanding of testing methodologies, including unit, integration, contract, and regression testing. - Working knowledge of containers, cloud environments, version control systems, CI/CD pipelines, and production observability. - Good system-design capabilities, with the ability to evaluate technical trade-offs and develop simple, scalable solutions. - Strong analytical, debugging, and problem-solving skills. - Excellent written and verbal communication skills, with the ability to explain technical decisions to non-technical stakeholders. Must-Have Skills - Python - Object-Oriented Design - Functional Design Good-to-Have Skills - AI Integration - Machine Learning - Conversational Interfaces Preferred Qualifications - Experience integrating AI or machine-learning capabilities into customer-facing applications. - Exposure to conversational interfaces, streaming systems, real-time media processing, or multilingual applications. - Familiarity with workflow eng
