Software Engineer III

 Software Engineer - III 

About the Role 

GHX is building a next-generation Intelligent Process Automation (IPA) platform powered by LLMs and AI-native document understanding. We extract structured data from complex healthcare procurement documents — Purchase Orders, invoices, contracts — at scale across cloud environments. As a member of the IPA engineering team, you will bridge strong software engineering with applied AI. You will design and ship Python services, integrate LLM APIs, build AI agents, create skills and validate the output of LLMs to build document extraction pipelines, and own evaluation infrastructure that ensures production quality. This is not a research role — it is a hands-on engineering role where AI fluency amplifies solid software craft. 

Core Responsibilities 

Python Development & Automation 

• Build and maintain Python-based automation services and IPA workflows 

• Develop platform-agnostic solutions supporting future migration across automation tooling 

• Build reusable libraries, frameworks, and components for automation projects 

• Integrate automation solutions with REST APIs and enterprise applications 

• Deploy and monitor automation bots on AWS (Lambda, ECS, SQS, S3) 
  
  

  AI & LLM Integration 

  • Integrate LLM APIs (like Anthropic Claude, OpenAI, Azure AI) into production pipelines 
  • Design classification and extraction prompts for diverse document types (POs, invoices, contracts) 
  • Write prompts that function as formal specifications — unambiguous, edge-case-aware 
  • Build and iterate few-shot, chain-of-thought, and structured output templates 
  • Own prompt library versioning, rollback strategy, and prompt lifecycle management

    Document Processing & IDP 

    • Implement OCR/IDP workflows to extract and validate structured and unstructured data 
    • Build confidence scoring frameworks for extracted fields with multi-factor validation 
    • Design and curate ground truth datasets for classification and extraction tasks 
    • Build automated evaluation pipelines tracking precision, recall, and field-level accuracy 
    • Validate model outputs against intent — catch what is technically correct but conceptually wrong 

    Software Engineering 

    • Design and build production-grade APIs and services around LLM capabilities 
    • Apply Clean Architecture or equivalent — design for testability and maintainability 
    • Contribute to CI/CD pipelines, observability tooling, and deployment processes 
    • Conduct code reviews, establish coding standards, and mentor junior engineers 
    • Troubleshoot and optimize existing automation workflows and Python services
