Job Description

We are building an AI-powered design-to-pricing platform for one of the leading textile manufacturers. The AI platform integrates material inventory, market intelligence, AI-generated collections, dynamic pricing, ESG tracking, and automated proposal generation into a single end-to-end workflow. As a Python Developer on this project, you will architect and build the backend services, data pipelines, and AI integration layers that power the platform.

Experience: 35 Years

Location: Kolkata

Key Responsibilities

Design, develop, and maintain backend services and REST APIs using FastAPI for the platform, covering modules such as material inventory indexing, research engines, pricing engines, and proposal generation.
Build and optimize data ingestion pipelines for SAP ERP exports, Excel/Google Sheets feeds, and third-party integrations (WGSN trend data, Nitva export data, pricing intelligence sources).
Develop the AI/ML integration layer connecting image generation APIs (for mood boards, styling, and collection creation), NLP services, and recommendation engines into the platform workflow.
Implement the cost master and dynamic pricing engine, handling complex calculations for knitting, dyeing, print, embroidery, and making costs with margin targets and brand-specific rules.
Build the data layer for the ESG impact matrix, capacity planning views, order book analytics, and delivery scheduling modules.
Design and maintain PostgreSQL database schemas, ensuring efficient querying for search and discovery, analytics dashboards, and reporting features.
Integrate with Elasticsearch for material search and discovery across yarn, fabric, colour, and garment data.
Collaborate with front-end developers (Next.js) on API contracts, and with the AI/ML engineer on model serving and inference pipelines.
Write automated tests (unit, integration, contract tests) and participate in cross-team integration testing with the client's data systems.
Contribute to CI/CD pipeline setup, deployment automation, and production monitoring on AWS/GCP infrastructure.
