Employer and industry usageUsed in tech, e-commerce, finance, and SaaS companies for backend servicesCommon across all industries requiring software solutions, including enterprise and consulting firms

Contract Backend Python Developers specialize in Python-based backend systems, focusing on API and server-side development. Contract Software Engineers have a broader scope, working with multiple programming languages and software components. While both roles require strong coding skills, Contract Backend Python Developers are more specialized in Python frameworks and backend architecture, making them ideal for projects centered on Python-based backend solutions.

What are the key skills and qualifications needed to thrive as a Contract Backend Python Developer, and why are they important?

To thrive as a Contract Backend Python Developer, you need strong proficiency in Python, experience designing and building APIs, and a solid understanding of databases and server-side architecture. Familiarity with frameworks like Django or Flask, version control systems like Git, and experience working with cloud platforms (such as AWS or Azure) are typically required. Excellent problem-solving skills, effective communication, and the ability to work independently are essential soft skills. These competencies ensure you can deliver robust, scalable backend solutions efficiently and collaborate seamlessly with cross-functional teams in a contract-based, deadline-driven environment.

What are some common challenges contract backend Python developers face when joining new projects?

Contract backend Python developers often encounter challenges such as quickly ramping up on unfamiliar codebases, adapting to varying development workflows, and integrating with existing teams remotely. Since contract roles are typically project-based and time-limited, developers must efficiently understand project requirements and existing infrastructure to contribute effectively from day one. Clear communication and proactive collaboration with team members, especially regarding code standards and deployment practices, are key to overcoming these challenges and ensuring smooth project delivery.

What is a Contract Backend Python Developer?

A Contract Backend Python Developer is a software engineer who specializes in building and maintaining the server-side logic of web applications using the Python programming language, typically on a temporary or project-based contract. They focus on developing APIs, databases, and other backend components that support the frontend of web or mobile applications. Unlike full-time employees, contract developers are usually hired for specific projects or timeframes, offering flexibility to both the developer and the employer.

Job description

We are only considering candidates based in Chicago. First interview will be on site in the Chicago office with a technical assessment. Please do not apply if this first phase is not possible.

We are looking for an AI Engineer to design, develop, and deploy an intelligent, multilingual chatbot that helps users track their parcels seamlessly. The chatbot will integrate with Snowflake for data retrieval, leverage APIs or web scraping to fetch tracking updates from external systems and run as a containerized solution on Azure. We are seeking to hire an engineer who is passionate about building scalable, AI-powered applications. You’ll work at the intersection of backend development and AI integration, leveraging modern tools like LLMs, MongoDB, Docker, and best coding practices. You’ll be responsible for writing clean, efficient, and maintainable code while working closely product teams to deploy intelligent systems. We need a proactive, self-motivated leader who thrives in a dynamic environment.

Key Responsibilities

  • Design, develop, and maintain an AI-powered chatbot capable of handling multi-lingual conversations.
  • Implement Retrieval-Augmented Generation (RAG) workflows to improve response accuracy and reduce unnecessary LLM calls
  • Integrate AI and LLM tools (e.g., OpenAI, LangChain, Hugging Face) into real-world applications
  • Integrate chatbot with Snowflake to fetch tracking data using tracking IDs.
  • Develop web scraping and API connectors to external parcel tracking systems
  • Deploy and manage chatbot services on Azure using Docker containers.
  • Implement vector databases (e.g., Pinecone, FAISS, Chroma) for efficient context management and response caching.
  • Ensure code quality through best practices: clean code, testing, and code reviews.

Must-Have Skills

  • Programming: Strong proficiency in Python and relevant libraries (e.g., LangChain, FastAPI, BeautifulSoup, Requests
  • AI Tools & Frameworks: Experience with OpenAI, Hugging Face, or similar AI API''''''''''''''''s
  • RAG Implementation: Hands-on experience integrating LLMs with vector databases and retrieval pipelines
  • NLP: Strong understanding of prompt design, token usage, embeddings, and language model
  • Data Integration: Experience connecting with Snowflake or similar dataware houses.
  • Deployment: Knowledge of Docker and Azure container deployments.
  • Web Scraping & APIs: Experience building scrapers or integrating with third-party APIs
  • Version Control: Familiarity with Git and CI/CD pipelines
  • Strong communication skills — able to explain complex AI concepts in simple terms
  • Collaborative attitude and openness to feedback

Nice-to-Have Skills

  • Familiarity with LLM orchestration frameworks (LangChain, LlamaIndex)
  • Exposure to multi-lingual NLP models or translation APIs
