We are seeking a dynamic and accomplished Python Developer to join our talented Engineering Enablement team. The ideal candidate will possess a unique blend of technical expertise in modern Python development and a passion for working with cutting-edge AI technology. As a key player in our organization, you should have a proven track record of delivering high-quality software, building scalable systems, and continuously learning new technologies.

At nShift, we're developing a cutting-edge system that streamlines carrier integrations through intelligent automation. This role offers the chance to work on a dynamic platform that combines traditional software development with AI-powered coding assistance to accelerate integration workflows.
We're seeking a pragmatic, hands-on developer who will design and build integration solutions that connect seamlessly with external and internal systems. You'll write production code while also developing AI coding agents that enhance and expedite the integration process, making it faster and more efficient for our team and clients.
No prior AI/LLM experience required - we're looking for strong software engineers who are excited to learn and work with cutting-edge AI technology. If you have solid engineering fundamentals and curiosity about AI, we'll help you develop the AI-specific skills.
