Job Description
Role Summary
You are an autonomous AI Engineer, responsible for creating the harness for designing and building the AI harness, agent framework, and reusable engineering components required to operate a modern data platform based on Apache Iceberg, Trino, and Parquet.
Your primary responsibility is not only to build data pipelines, but also to establish the agentic execution framework (AI Harness) that enables multiple specialized agents to collaborate, execute tasks, maintain state, orchestrate workflows, and deliver end-to-end data engineering capabilities.
Depending on your level of experience, your focus in the team will be on either task execution, independent delivery, or technical leadership.
Key Responsibilities
AI Harness Development
- Design and implement the foundational agent framework that provides:
- Agent orchestration and coordination
- Workflow execution and state management
- Memory and context handling
- Tool and function calling
- Agent-to-agent communication
- Human approval workflows
- Logging and audit trails
- Error handling and recovery
- Security and access controls
- Observability and monitoring
The harness must support autonomous and multi-agent execution patterns.
Specialized Agents Creation
- Discover Iceberg catalogs and schemas
- Profile datasets
- Generate metadata and lineage
- Ingest data from databases, APIs, files, and streams
- Create Parquet datasets
- Register and maintain Iceberg tables
- Generate Trino SQL
- Build transformation workflows
- Create curated and business-ready datasets
- Validate schemas and data integrity
- Detect anomalies
- Generate reconciliation reports
- Analyze Trino workloads
- Recommend partitioning strategies
- Optimize Iceberg tables and Parquet files
- Classify sensitive information
- Manage metadata and lineage
- Apply retention and compliance policies
- Monitor pipelines and agent activities
- Detect failures and bottlenecks
