Due to the high demand for Snowflake developers (doing Cloud data warehousing), they are getting good hourly rates. A capable Snowflake developer can cost you anywhere between $70-150 per hour. Like any niche experience, circumstances affect pricing (experience, location, and project scope).
Higher fees can be expected for consultants with more experience designing, implementing, and maintaining Snowflake data warehouses in a large-scale environment. If your project needs an expert in certain Snowflake technologies, like data integration security, or performance optimization, prepare to pay a higher price.
