Role Overview

We are looking for a Junior Python Developer to join the backend development team for Enso One, our next-generation business application platform.

This role is suitable for candidates with 0-3 years of experience who have strong fundamentals in Python, backend API development, relational databases, data processing, and Git-based development.

The selected candidate will work on FastAPI-based backend services, PostgreSQL-backed business logic, data/file processing workflows using pandas, integrations, and internal automation utilities.

Key Responsibilities

• Develop and maintain backend APIs using Python and FastAPI.
• Write clean, readable, modular, and maintainable Python code.
• Work with PostgreSQL databases, including queries, joins, indexes, constraints, and schema changes under guidance.
• Build and maintain data processing scripts using pandas for CSV, Excel, and structured data workflows.
• Debug API, database, and data transformation issues using logs and structured troubleshooting.
• Use Git for branching, commits, pull requests, and team collaboration.
• Participate in code reviews and improve based on feedback from senior developers.
• Write basic unit tests and validate edge cases for APIs and data-processing logic.
• Support integrations with internal and external systems through REST APIs.
• Document technical assumptions, API behavior, and implementation notes clearly.

Mandatory Skills

• Python fundamentals: functions, classes, exceptions, data structures, file handling, comprehensions, and virtual environments.
• FastAPI basics: route creation, request/response models, validation, dependency usage, status codes, and error handling.
• PostgreSQL basics: SQL queries, joins, filtering, grouping, transactions, constraints, and basic performance awareness.
• pandas basics: reading/writing CSV and Excel files, cleaning data, filtering, grouping, merging, handling nulls, and exporting processed outputs.
• Git basics: clone, branch, commit, pull, push, merge conflict resolution, and pull request discipline.

Preferred Practical Exposure

• Basic Linux usage, command line navigation, logs, environment variables, and application troubleshooting.
• Understanding of API testing using tools such as Postman, curl, or similar tools.
• Awareness of authentication basics such as sessions, tokens, JWT, password hashing, and access control concepts.
• Understanding of clean coding practices, naming discipline, and basic code organization.
• Basic awareness of deployment flow, configuration files, and server-side debugging.

Required Candidate Profile

• 0-3 years of hands-on experience or strong project/internship experience in Python development.
• Strong problem-solving ability and willingness to learn business workflows in depth.
• Comfortable working in a structured engineering environment with code reviews and task tracking.
• Able to ask clear questions, document assumptions, and communicate blockers early.
• Detail-oriented approach to data correctness, API behavior, and database consistency.
• Willing to work full-time from the Bangalore office.

What the Candidate Will Work On

• Backend APIs for Enso One modules and internal workflows.
• Database-driven business logic using PostgreSQL.
• Data import, validation, transformation, and reporting utilities.
• File processing for structured formats such as Excel and CSV.
• Internal automation scripts to reduce manual operational work.
• Integration support for internal tools and third-party systems.

Good to Have

• Exposure to SQLAlchemy, Alembic, Pydantic, pytest, Docker, or similar tools.
• Experience building small personal or academic projects using Python APIs and databases.
• Understanding of background jobs, scheduled scripts, queues, or async processing concepts.
• Interest in building reliable business applications with strong data accuracy requirements.

Selection Process

• Initial resume screening.
• 45-minute Google Form technical assessment.
• Technical interview focused on Python, PostgreSQL, FastAPI, pandas, Git, debugging, and practical problem solving.
• Final discussion on role fit, work discipline, and learning ability.

Success Expectations

• Within 30 days: understand the codebase, setup flow, Git workflow, and basic Enso One backend modules.
• Within 60 days: independently complete small API, SQL, and data-processing tasks with review support.
• Within 90 days: handle moderate backend tasks, debug issues methodically, and contribute reliably to sprint delivery.
