Principal Software Engineer, Back-End .NET

Description

Location: Remote, USA

Enterprise AI Workflow Integration | Regulatory / Compliance-Driven Products

About the Role

We are seeking a Principal .NET Software Engineer to help lead the evolution of our enterprise platform in a highly regulated, compliance-driven industry. This role is ideal for a senior technical leader who has deep expertise in building scalable back-end systems with the Microsoft technology stack and AWS, with hands-on experience integrating AI-enabled workflows into real-world enterprise workstreams.

As a Principal Engineer, you will operate at the intersection of architecture, product delivery, engineering excellence, and applied AI. You will be expected to design and deliver resilient back-end services, guide technical strategy, mentor senior engineers, and help establish practical patterns for safely incorporating AI capabilities into production systems where accuracy, auditability, security, and compliance are critical.

This is not a purely research-focused AI role. We are looking for someone who understands how to apply AI pragmatically inside enterprise software: automating workflows, enhancing decision support, improving data extraction, enabling intelligent recommendations, streamlining compliance operations, and embedding human-in-the-loop controls where needed.

Key Responsibilities
