Spherecast
Spherecast is a Y Combinator-backed supply chain platform whose AI manager, Agnes, plans and executes inventory decisions for consumer brands. The company is hiring a Senior Integration Engineer to own the integration layer that connects its platform to external systems: ERPs such as NetSuite, cloud storage such as S3 and FTP, and data warehouses such as Snowflake, Databricks and BigQuery. This is an on-site role in New York City. Spherecast advertises the role with visa sponsorship in the job title itself, "Senior Integration Engineer (Visa Sponsorship)", which is the employer's own signal that it will sponsor a work visa for the right international hire; the body of the posting does not add a separate sponsorship sentence, so confirm specifics during the process. Salary is not disclosed. Freshness evidence: the posting went live on Spherecast's Ashby board on 2026-09-23 (its sibling Senior Full-Stack Engineer role was published the day before, so the board is not a bulk republish).
