Senior AI Search & Agentic Systems Engineer

TechDigital Group; Santa Clara (CA); On-site; USD 140,000 - 210,000; Full time

Job summary

TechDigital Group in Santa Clara, CA is seeking a Senior Software Engineer to design and build intelligent search and agentic automation systems. You will work across the stack—from backend services and data pipelines to AI-driven retrieval and agent orchestration—to deliver production-grade solutions.

You will implement RAG pipelines, Claude-based agents, and scalable data models with PostgreSQL, while ensuring code quality, security, and CI/CD across services.

Qualifications

• Strong proficiency in Python and Java (Spring Boot or equivalent frameworks).
• Hands-on experience with React.js for front-end development.
• Deep expertise in Elasticsearch — index design, aggregations, query DSL, performance tuning.
• Experience with Azure AI Search (formerly Cognitive Search) — semantic search, vector indexing, hybrid search.
• Practical experience building RAG (Retrieval-Augmented Generation) systems, including embedding generation, vector stores, and LLM integration.
• Experience building or integrating Claude agents and Claude Skills (or similar LLM agent frameworks) for task automation.
• Solid experience with PostgreSQL — schema design, optimization, and query writing.
• Understanding of API design (REST/GraphQL) and microservices architecture.
• Familiarity with cloud platforms (Azure preferred; AWS/GCP a plus).
• Experience with Kubernetes and containerized deployments are a plus.

Responsibilities

• Design, develop, and maintain backend services using Java (Spring Boot) and Python, ensuring scalability, reliability, and performance.
• Build and enhance React.js front-end applications with clean, responsive, and intuitive user interfaces.
• Architect and optimize search solutions using Elasticsearch and Azure AI Search, including index design, query performance tuning, and relevance optimization.
• Implement Retrieval-Augmented Generation (RAG) pipelines to power intelligent search and Q&A experiences, integrating vector search with LLM-based generation.
• Design and deploy Claude-based agents and Claude Skills to automate workflows, orchestrate multi-step tasks, and integrate with internal/external systems.
• Develop and manage data models and queries using PostgreSQL, ensuring efficient schema design and query performance.
• Collaborate with cross-functional teams (product, data, DevOps) to translate business requirements into technical solutions.
• Ensure best practices in code quality, testing, security, and CI/CD across all systems.
• Monitor, troubleshoot, and optimize system performance in production environments.
