Job Description
We are looking for a Trino Developer who can own query engine performance, lead migration of existing
pipelines and warehouses, and help establish a scalable, cost-effective lakehouse architecture.
You will work at the intersection of query engineering, data modeling, and platform operations - translating
legacy Snowflake/Spark logic into performant Trino + Iceberg workloads while ensuring correctness, parity, and
reliability.

Roles Responsibilities
Hands-on production experience with Trino (or PrestoSQL/Presto).

- Strong, deep SQL expertise - complex analytical queries, window functions, CTEs, query optimization.

- Hands-on experience with Apache Iceberg (or comparable open table formats - Delta Lake, Hudi)
including schema/partition evolution and table maintenance.

- Practical experience with Snowflake and/or Apache Spark - enough to read, understand, and migrate
existing workloads.

- Understanding of distributed query execution: MPP architecture, join distribution, memory/spill behavior,
partition pruning, and predicate pushdown.

- Experience with cloud object storage and columnar file formats (Parquet, ORC).

- Proficiency in at least one programming language (Python, Java, or Scala) for tooling, UDFs, and




automation.

- Version control (Git) and CI/CD for data pipelines.

Technical Requirement
Experience leading a Snowflake Trino or Spark Trino migration at scale.

- Trino cluster administration and deployment on Kubernetes.

- Workflow orchestration (Airflow, Dagster, or similar) and dbt.

- Experience building data-validation / reconciliation frameworks for migration parity.

- Knowledge of Trino internals or connector development (contributing custom connectors/UDFs).

- Streaming/CDC ingestion into Iceberg (Kafka, Flink, Debezium).

- Data governance, lineage, and cost-optimization tooling.

Additional Responsibility
Strong analytical and problem-solving mindset for debugging correctness and performance issues.

- Clear communication - able to document migration decisions and work with analytics, platform, and
business teams.

- Ownership mentality with attention to data correctness and reliability.
