Job summary

Weekday seeks an experienced Python Engineer to join a client project in NCR (Gurugram), Haryana, India. You will build production-grade Python services, design scalable architectures, and integrate internal and external systems, including AI-enabled product experiences.

The role covers backend development, asynchronous workflows, API design, and production observability. 5+ years of experience and strong coding skills are required to succeed in this product engineering environment.

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.

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.
