Software Engineer II

Position:  Software Engineer II

Duties:

Design, develop, and maintain full-stack AI-driven web applications and microservices using Python, Java, and React, delivering both high-quality prototype systems and production-ready applications that meet performance and reliability standards.
Build, deploy, and optimize RESTful API backend services using FastAPI and Flask frameworks; implement and consume APIs across distributed application layers to support real-time document processing and large-scale data pipelines.
Develop and maintain frontend user interfaces using React, including researcher dashboards, administrative consoles, and data visualization components, applying user interaction best practices.
Integrate large language model (LLM) APIs and retrieval-augmented generation (RAG) pipelines — including prompt engineering, cost optimization, hallucination heuristics, and output evaluation — into production software systems to enable intelligent document processing, semantic search, and automated generation capabilities.
Design and implement data storage, retrieval, and management solutions using relational databases (PostgreSQL, MySQL) and NoSQL databases (MongoDB); manage document-scale data operations and data integrity across large corporations.
Deploy, manage, and monitor containerized microservice applications on AWS cloud infrastructure using Docker, applying scalability and operational efficiency best practices across development and production environments.
Collaborate with AI researchers, product managers, designers, and cross-functional engineering teams to design and implement human-AI workflow tools and applied AI research products, owning end-to-end development of key platform components. 

Requirements:

This position requires a Bachelor’s degree or equivalent in Computer Science, Computer Engineering, Information Technology, or a closely related field and 3 years of experience in using full-stack AI software development, including AI frameworks, backend API development and frontend development using modern web frameworks.

Demonstrated experience implementing search and information retrieval solutions using Elasticsearch.
2 years of demonstrated experience integrating LLM APIs and RAG pipeline frameworks, including Langchain, into production AI applications.
Demonstrated experience working with NLP techniques including named entity recognition (NER), text classification, and topic modeling, using libraries such as NLTK, SpaCy, or Scikit-Learn.
2 years of demonstrated experience working and collaborating with AI researchers to develop and deploy AI models into production systems.
Demonstrated experience containerizing and deploying applications using Docker on AWS cloud infrastructure, including AWS S3.
Employer will accept experience gained concurrently.
