Senior Python Developer

We are building a next-generation Collaborative Intelligence Platform for the chemical supply chain. Our goal is to move beyond traditional static dashboards (“The Bloomberg Terminal”) and create an agentic, workspace-based platform (“The Notion for Procurement”), powered by a proprietary thermodynamic model.
The platform combines advanced data pipelines, AI-driven agents, real-time collaboration tools, and deep domain analytics to help global chemical companies make faster and more accurate procurement decisions.

Responsibilities:‍

• Write clean, efficient, scalable, and well-documented code with a strong focus on performance and robustness.
• Design, develop, and maintain backend services, APIs, and internal tools using Python.
• Develop microservices and distributed systems aligned with modern architectural principles.
• Implement and maintain REST and GraphQL APIs for internal and external consumption.
• Work with relational and NoSQL databases (primarily PostgreSQL), optimizing queries and data models for high-load scenarios.
• Integrate FastAPI, LangGraph, LangSmith, and RAG-based components into the product ecosystem.
• Collaborate with AI/ML teams to integrate intelligent agents and complex computational logic (including thermodynamic modelling).
• Implement asynchronous tasks using Celery, Django Channels, or other async frameworks.
• Ensure platform security: encryption, access control, secure data flows, and compliance with audit and logging requirements.
• Participate in architectural decision-making, code reviews, and system design sessions.
• Develop and maintain CI/CD pipelines for automated testing and deployment.
• Build and maintain integrations with external APIs, analytical systems, and payment providers.
• Monitor system health and performance using modern observability tools (logging, monitoring, tracing).
• Work closely with product, DevOps, and frontend teams in an agile environment.
• Provide mentorship to mid-level and junior developers when needed.

Required qualification:

• 4+ years of commercial experience as a Python Developer.
• Strong proficiency with Django and experience with FastAPI.
• Experience with LangGraph, LangSmith etc.
• Deep understanding of microservices, distributed architecture, and high-load systems.
• Strong experience with PostgreSQL and understanding of relational and NoSQL data modelling.
• Experience building and consuming REST and GraphQL APIs.
• Practical knowledge of asynchronous frameworks, such as Celery, Django Channels, asyncio.
• Experience working with encryption, secure data storage, and best security practices.
• Experience developing and supporting systems with audit, logging, monitoring, and incident response requirements
• Experience with Docker, Kubernetes, and containerized environments.
• Confidence in CI/CD workflows and tools (GitHub Actions, GitLab CI, Jenkins, etc.).
• Experience with external API integrations (analytics, payments, enterprise tools).
• Excellent debugging, profiling, optimization, and system design skills.
• English level B2+, enabling effective technical communication.

‍Nice to have:
‍

• Experience implementing RAG (Retrieval Augmented Generation) pipelines.
• Familiarity with data pipelines and ETL/ELT architecture.
• Experience in enterprise products for supply chain, logistics, procurement, or scientific/engineering tools.
• Security certifications or hands-on experience with compliance frameworks (SOC 2, ISO, etc.).
