Senior Developer

Job Description: Senior AI/NLP Engineer (Medical Text Analytics)

We are Hiring Senior Developer.

• Experience: 2-3 years of software engineering experience with a strong focus on Python and Data/Machine Learning pipelines.
• Immediate joiner/ 15 days notice accepted

About the Role

We are seeking a Senior AI/NLP Engineer to optimize and enhance our automated clinical coding pipeline. Our system processes medical documents (PDFs/Text) to extract structured clinical entities and leverages semantic search and Large Language Models (LLMs) to accurately predict CPT and ICD-10 codes.

You will be responsible for refactoring the existing codebase, eliminating technical debt, optimizing vector search performance, and fine-tuning prompt engineering for local LLM deployments.

Required Qualifications

• NLP & Deep Learning: Proven experience working with NLP libraries (spaCy, NLTK) and Transformer models (Hugging Face, Pipeline API).
• Vector Search: Hands-on experience building and optimizing semantic search engines using FAISS and SentenceTransformers.
• Local LLMs: Familiarity with deploying, running, and prompting open-source LLMs locally (e.g., using Ollama, vLLM).
• Data Processing: Strong proficiency with pandas, complex RegEx, and text manipulation. Experience extracting data from PDFs (e.g., fitz/PyMuPDF) is highly desirable.
• Database Skills: Solid understanding of SQL and hands-on experience integrating Python with MS SQL Server.
• Windows Ecosystem: Experience deploying Python scripts using Windows Task Scheduler or as Windows Services.
• Software Craftsmanship: Strong advocate for clean code, configuration management, version control (Git), and CI/CD practices.

Key Responsibilities

• Pipeline Optimization: Optimize and enhance the existing Python-based extraction and analysis pipelines. Refactor code to improve modularity, remove redundant legacy components, and manage configuration centrally.
• NLP & Semantic Search: Maintain and optimize FAISS-powered nearest-neighbor search systems using SentenceTransformers (all-MiniLM-L6-v2).
• LLM Integration: Manage and optimize local LLM deployments (e.g., Mistral via Ollama), focusing on prompt engineering to accurately extract clinical entities and reason about medical codes.
• Text Extraction: Support and improve robust text extraction processes from medical PDFs using PyMuPDF and spaCy for sentence segmentation and header detection.
• Technical Debt Reduction: Identify and resolve hardcoded paths, duplicated logic, and inactive code paths across all pipeline modules.
• Database Integration: Optimize interactions with MS SQL Server databases using pyodbc for fetching chart/patient metadata and logging pipeline results.
• Deployment: Package and deploy Python scripts as scheduled tasks on Windows Server environments.

Preferred Qualifications

• Experience working with medical data, unstructured clinical notes, or medical coding standards (ICD-10, CPT, HL7).

Experience with extremely fast text processing libraries like FlashText and RapidFuzz
