Environmental Engineer/Scientist (Stormwater)

Portland, Oregon

Terraphase Engineering is seeking a Project Environmental Engineer / Scientist with an emphasis on industrial stormwater in one of our Northwest offices (Portland or Tacoma).

The Project Environmental Engineer / Scientist will perform complex consulting assignments and support the management and execution of technical projects focused on day-to-day environmental regulatory compliance. This role serves industrial, municipal, and construction clients across a range of compliance programs, with a strong emphasis on stormwater.

Key subject areas include industrial, municipal, and construction stormwater; hazardous waste and materials; solid waste; wastewater; and water quality.

Responsibilities include delivering multimedia compliance services such as stormwater program development and implementation, hazardous waste and materials management, wastewater compliance, and on-site compliance inspections and audits. The Project Environmental Engineer / Scientist will routinely review and interpret regulations, permits, and agency guidance to support project needs and ensure accurate, up-to-date application of regulatory requirements.

This position requires the ability to evaluate technical and regulatory issues and clearly communicate findings and recommendations to internal teams, clients, and regulatory agencies. Fundamental project management skills are essential, including the ability to coordinate tasks, manage multiple assignments simultaneously, meet deadlines, and effectively prioritize work across concurrent projects. The role requires a willingness to perform both field-based (on-site) work and office-based work, depending on project needs. Project management responsibilities—including task coordination, client communication, and strong self-management—are integral to the role.
