• Contact Python Engineer (0–2 Yrs) Role Overview Efficienza is looking for a Python Engineer to join a fast-moving team building backend services, APIs, and data-driven applications. This role is ideal for candidates with strong Python fundamentals and an interest in backend development, whether gained through internships, academic projects, or self-driven learning. You will contribute to backend systems and data workflows that support both internal and client-facing products. We value engineers who take initiative, learn independently, ask thoughtful questions, and enjoy solving real-world technical problems.

You Will Excel If You

• Write clean, readable Python code and maintain code standards as systems grow
• Understand how APIs, databases, and services work together before implementation phase.
• Use documentation, logs, and available resources to investigate problems and learn independently
• Take ownership of assigned work, communicate blockers early, and follow through reliably
• Stay curious about backend systems, APIs, data flows, and how real-world applications are built and scaled Key Responsibilities Python Development and Code Quality
• Write clean, well-structured Python code following agreed conventions across functions, modules, and packages
• Break down assigned features into logical components with clear input, output, and error handling before implementation
• Use object-oriented programming concepts such as classes, inheritance, composition, and abstraction to build scalable backend applications
• Apply Python fundamentals correctly: data structures, comprehensions, generators, context managers, and exception handling
• Write code that is modular, reusable, and easy to extend as requirements evolve
• Write basic unit tests for functions and modules using pytest to validate behaviour and catch regressions early Backend Services and API Development
• Build and maintain RESTful API endpoints using FastAPI or Flask, following consistent naming and response conventions
• Implement request validation, error handling, and structured response formatting across all endpoints
• Work with relational databases: write queries, manage schema changes, and validate data integrity
• Integrate with internal and third-party APIs, handling authentication, request validation, error responses, and service interactions
• Work with external services and APIs, understand how they communicate, and troubleshoot integration issues when they arise Database and Storage
• Write and optimize SQL queries for PostgreSQL across read, write, and aggregation use cases
• Understand database schema design at a basic level: normalization, foreign keys, indexes, and the tradeoffs involved
• Validate that data flows correctly between APIs, business logic, and storage layers
• Work on caching and session storage by understanding basic data structures
• Assist in maintaining database migrations and understand their impact on existing data and services Initiative and Independent Work
• Take ownership of assigned tasks from implementation through testing and review
• Raise ambiguities, dependencies, and blockers early instead of waiting until deadlines
• Propose implementation approaches and seek feedback when requirements are unclear Collaboration and Communication
• Collaborate with engineers during sprint activities and communicate progress, blockers, and dependencies clearly
• Learn from code reviews and architectural guidance, applying established engineering standards consistently
• Contribute to documentation and seek feedback early to ensure implementations align with team practices and expectations Required Technical Knowledge Area Details
