## Description

ICF's Technology and Products team is seeking a On-call S oftware Engineer, Cloud Data Platform to help build, enhance, and support a cloud-hosted relational database platform for acoustic-telemetry fish-tracking research in California's Sacramento-San Joaquin Delta.

This role will focus on the core engineering work needed to turn post-processed fish detection data into reliable, usable data products, including ingestion pipelines, relational data models, validation logic, reporting views, exports, APIs, and production support.

You will work alongside fish biologists, data scientists, senior engineers, and a state agency client to move the platform from design through go-live and into production support. This is a hands-on engineering role where you will contribute to platform design, implementation, and operations with guidance from senior technical leads.

This is a remote, on-call role that provides flexibility to work from 0 to 40 hours per week.

About On-Call Employment with ICF

Given the seasonal and project-specific nature of this work, ICF often hires professionals as "On-Call" employees. On-Call employees are scheduled for work hours as they become available. ICF usually schedules work hours a few weeks ahead of time, and each on-call employee is free to accept or refuse the hours assigned to them in a given week. On-Call employees may work concurrent projects outside their ICF assignment as long as the outside work does not create a conflict of interest., Platform, data, and operations

 * Translate scientific, regulatory, and analytical needs into clear technical requirements in partnership with biologists, data scientists, agency staff, client stakeholders, and senior technical team members.
 * Contribute to the design, build, and support of a cloud-hosted relational database platform for acoustic-telemetry fish-tracking data.
 * Build and maintain relational data models, ingestion workflows, ETL/ELT pipelines, validation logic, and data quality controls for high-volume telemetry detection data.
 * Develop reporting views, aggregations, exports, APIs, and structured access patterns that support downstream modeling, analysis, and non-SQL users.
 * Support platform performance, security, access controls, monitoring, backups, retention, documentation, and production operations during go-live and ongoing hosting.
 * Help support a natural-language query interface by contributing to schema grounding, result validation, access safeguards, and accuracy guardrails.
