Python/GenAI Developer

CAI is seeking a Python/GenAI Developer for a contract, remote role focused on building enterprise AI applications.

Responsibilities

• Design, develop, and maintain Python-based backend services and APIs for AI-enabled applications, emphasizing clean, modular, production-ready code
• Build and integrate Generative AI workflows using LLMs, RAG pipelines, prompt orchestration, and structured-output processing
• Develop FastAPI-based REST endpoints for file processing, pipeline execution, asynchronous workflows, and integrations with external enterprise applications
• Implement retrieval workflows using GCP services including Vertex AI, Vertex AI Search, Cloud Storage, BigQuery, Pub/Sub, Secret Manager, and Cloud Run
• Create data-processing logic for structured and unstructured inputs such as document parsing, metadata generation, validation, transformation, and downstream persistence
• Support integration testing, debugging, deployment, logging, monitoring, and troubleshooting across development and QA environments
• Collaborate with solution architects, cloud infrastructure teams, product owners, and business stakeholders to translate requirements into scalable AI features and backend components
• Improve reliability of AI pipeline responses through prompt engineering, output validation, error handling, retry logic, and guardrails
• Maintain technical documentation, API contracts, configuration files, deployment artifacts, and reusable engineering components

Requirements

• 4-7 years of software development experience, including strong hands-on Python backend development (OOP, modular coding, exception handling, testing, package management)
• 1-2 years practical experience with Generative AI and LLM-based applications (prompt engineering, structured outputs, model invocation, response validation, token usage, basic evaluation concepts)
• 1-2 years practical experience with RAG solutions (document ingestion, chunking, embeddings, vector retrieval, metadata filtering, reranking, grounding)
• Experience building REST APIs using FastAPI, Flask, or similar Python frameworks (endpoint development, request/response models, authentication, async processing, status handling, API integration)
• Hands-on experience with Google Cloud Platform, especially Cloud Run, Cloud Storage, Vertex AI, BigQuery, Pub/Sub, IAM, and Secret Manager
• Experience integrating AI/ML services into enterprise applications using APIs, authentication, asynchronous processing, and cloud-native services
• Experience with cloud-native development including Docker, service accounts, environment variables, secrets, CI/CD, deployment, and runtime troubleshooting
• Experience processing structured and unstructured data formats including JSON, JSONL, Excel, CSV, PDF, Word documents, and text
• Experience with source control, CI/CD, containerization, and deployment workflows using Git, Docker, GitLab/GitHub, and cloud deployment pipelines
• Exposure to debugging distributed or cloud-hosted applications using logs, monitoring, request tracing, and error analysis
• Experience working in Agile teams and collaborating with cross-functional stakeholders

Technology Stack

• Python, FastAPI, Flask
• LLMs, RAG
• Vertex AI, Vertex AI Search
• Cloud Storage, BigQuery, Pub/Sub, Secret Manager, Cloud Run
• Docker, Git, GitLab, GitHub
• Google Cloud Platform, IAM
• JSON, JSONL, Excel, CSV, PDF, Word

Preferred

• Experience with Agentic AI frameworks or multi-step AI orchestration
• Familiarity with Vertex AI Vector Search, Graph RAG, or knowledge graph concepts
• Experience with Pub/Sub-based asynchronous processing and event-driven architectures
• Understanding of OAuth, service-to-service authentication, IAM, signed URLs, and secure API integration
• Exposure to React or frontend integration (useful but not mandatory)
• Familiarity with AI evaluation metrics such as groundedness, relevance, completeness, coherence, and confidence scoring
• Healthcare-domain exposure, particularly for enterprise workflow, requirements, or document intelligence

Compensation

• USD 65 - 70 per hour

Benefits

• Medical, dental, and vision insurance
• 401k retirement account access
• Paid sick leave and/or other paid time off as provided by applicable law
