Python Developer

Role Overview

Senior Python Backend Engineer focused on shipping AI-powered features in production (not research). This is a contract role, remote (US), building reliable backend services and REST APIs that real users depend on.

Responsibilities

• Design and build Python backend services and REST APIs for production applications
• Integrate LLMs and AI APIs (e.g., OpenAI, Anthropic) into real workflows and existing systems
• Own reliability: error handling, edge cases, and performance
• Write clean, testable code with proper version control, peer reviews, and Agile practices
• Work with SQL databases and optimize queries for production workloads
• Collaborate with engineering and non-technical stakeholders
• Occasionally interface with .NET/C# systems within a broader stack

Requirements

• 5+ years of professional software engineering experience
• Strong hands-on Python backend development (APIs, microservices, production systems)
• Proven experience integrating LLMs/AI APIs into deployed applications
• Solid C# / .NET (including .NET Core)
• Strong SQL skills with relational databases
• Experience with API microservices architecture and object-oriented design
• Testing mindset: unit tests, code reviews, and data-driven validation
• Clear communicator; can work independently and in a small Agile team

Nice to Have

• Cloud experience, ideally Azure
• Familiarity with ML frameworks (TensorFlow, PyTorch, Scikit-learn)
• Background in data/ML engineering

What This Role Is Not

• Not a data science/research role (no model experimentation, analytics dashboards, or Jupyter-notebook-focused work).

Logistics

• Remote (US) with a short onsite onboarding visit in San Francisco (2–3 days)
• C2H (1099) contract structure
• Compensation: competitive with the Canadian market, based on experience
