• Develop RESTful APIs and real-time streaming endpoints using frameworks like Fiber or Chi
• Implement type-safe database operations using SQLC, GORM, or raw SQL with PostgreSQL
• Build and optimize analytical query engines using DuckDB and MotherDuck for OLAP workloads

AI/ML Integration

• Integrate and orchestrate multiple LLM providers (OpenAI, Anthropic, Google Gemini) with pluggable adapter patterns
• Build NL2SQL pipelines that convert natural language queries to validated SQL
• Implement vector search and embedding pipelines for semantic search capabilities
• Design streaming response architectures for real-time AI interactions

Data & Infrastructure

• Design multi-tenant data architectures with proper isolation and access control
• Implement authentication/authorization using OAuth 2.0/OIDC and fine-grained access control
• Build cloud storage integrations for file management
• Write database migrations and maintain schema evolution strategies

Quality & Leadership

• Write comprehensive unit and integration tests with high coverage
• Conduct code reviews and enforce coding standards
• Mentor junior developers and contribute to architectural decisions
• Document APIs using OpenAPI/Swagger specifications

• Hands-on experience with PostgreSQL including query optimization, indexing, and migrations
• Experience building and consuming RESTful APIs with proper error handling
• Proficiency with Docker and container orchestration basics
• Experience with Git workflows and CI/CD pipelines
• Strong understanding of authentication/authorization patterns (OAuth 2.0, JWT)
• Excellent problem-solving skills and attention to code quality

Preferred Qualifications

• Experience with analytical databases (DuckDB, ClickHouse, or similar OLAP systems)
• Familiarity with LLM/AI integrations (OpenAI API, LangChain)
• Experience with message queues (NATS, RabbitMQ, Kafka)
• Knowledge of Kubernetes and cloud platforms (GCP, AWS)
• Contributions to open-source projects

Nice to Have
