Job description

Job Title: GCP Gemini AI Developer (3-5 Years Experience)

Location: Remote / Hybrid - Chicago preferred

Employment Type: Contract / Full-Time

Reports To: GCP Technical Lead / AI Program Manager

Purpose

The GCP Gemini AI Developer will design, build, and deploy intelligent applications leveraging Google Cloud’s Gemini models and Vertex AI platform. This role exists to operationalize advanced GenAI capabilities — including natural language understanding, multimodal reasoning, and generative automation — within scalable, secure, and production-ready cloud environments. The developer will work hands-on across data engineering, AI model orchestration, and API integration to create AI-driven business solutions that reduce manual effort, enhance decision-making, and unlock measurable value from enterprise data.

Key Performance Outcomes (6–12 Months)

1. Gemini-Powered Solutions Deployed Design, develop, and deploy at least two Gemini-based AI solutions (e.g., document summarization, chat agent, or data extraction automation) using Vertex AI + Gemini APIs. Delivered to production with >90% accuracy and <2s response time.

2. Scalable Cloud Architecture Build a modular AI microservices framework using Cloud Run / Cloud Functions with integrated authentication, logging, and monitoring. Reusable components adopted in at least 3 future use cases.

3. RAG / Context-Aware Workflows Implement Retrieval-Augmented Generation (RAG) pipelines combining Gemini + BigQuery or vector databases for knowledge grounding. Demonstrated 25% reduction in hallucination or response variance.

4. Cross-Team Enablement Partner with Data, Automation, and AppDev teams to integrate Gemini AI into existing business workflows (e.g., UiPath, Power Platform, or ServiceNow). Minimum of 2 successful integrations with documented ROI.

5. Continuous Optimization Monitor, retrain, and improve AI models via Vertex AI pipelines and Model Monitoring. Demonstrated 15% performance gain over baseline models.

Core Responsibilities

• Design and deploy Gemini 1.5 Pro/Flash integrations via Vertex AI and Generative AI Studio.
• Build serverless APIs and backend services for AI workflows using Cloud Run, Functions, or App Engine.
• Develop data ingestion and preprocessing pipelines using BigQuery, Dataform, and Pub/Sub.
• Apply prompt engineering and parameter tuning to improve generative model accuracy.
• Implement RAG pipelines leveraging Vertex Matching Engine or Pinecone.
• Collaborate with automation and data teams to embed AI into existing business processes.
• Maintain compliance with security, privacy, and model governance standards.

Technical Environment

Core Google Cloud Services

• Vertex AI, Generative AI Studio, Gemini API
• BigQuery, BigQuery ML, Dataform
