We may receive/collect the following categories of Personal Data in the US: identity data, contact data, employment related data, marketing and communications data, technical data, such as IP addresses.

The way in which we collect and process identity data (such as first name, last name, username or similar) will depend on how you interact with us through our website e.g., via contact us link, careers site. This is information you will provide via the website or other channels, and this also includes any contact data you provide, such as email address. We will use this information to respond to an enquiry you may have made or a job application you have submitted.

Employment related data captured via our careers site is required to make a decision on the job application submitted.

Additional personal data is collected and processed on appointment. The processing of employment data is necessary for compliance with employment legal obligations.

We will use your data to send you marketing information if you have requested to receive this from Tetra Tech.

Technical data captured and processed through automated technologies (such as IP address and browser type) is processed in line with our cookie policy available on our website.

Tetra Tech will only process Personal Data in ways that are compatible with the purpose that Tetra Tech collected it for, or for purposes the individual later authorizes. Before we use your Personal Data for a purpose that is materially different than the purpose we collected it for, or that you later authorized, we will provide you with the opportunity to opt out. Tetra Tech maintains reasonable procedures to help ensure that Personal Data is reliable for its intended use, accurate, complete and current.

When we collect sensitive Personal Data, we will obtain your opt-in consent where the Data Privacy Framework requires, including if we disclose your sensitive Personal Data to third parties, or before we use your sensitive Personal Data for a different purpose than we collected it for, or than you later authorized.

Data transfers to Third Parties

Third-Party Agents or Service Providers

We may transfer Personal Data to our third-party agents or service providers who perform functions on our behalf. Where required by the Data Privacy Framework, we enter into written agreements with those third-party agents and service providers requiring them to provide the same level of protection the Data Privacy Framework requires and limiting their use of the data to the specified services provided on our behalf.

We take reasonable and appropriate steps to ensure that third-party agents and service providers process Personal Data in accordance with our Data Privacy Framework obligations and to stop and remediate any unauthorized processing. Under certain circumstances, we may remain liable for the acts of our third-party agents or service providers who perform services on our behalf for their handling of Personal Data that we transfer to them.

In some cases, we may transfer Personal Data to unaffiliated third-party data controllers. These third parties do not act as agents or service providers and are not performing functions on our behalf. We may transfer your Personal Data to third-party data controllers for the purposes described in our Website Privacy Policy.

We will only provide your Personal Data to third-party data controllers where you have not opted-out of such disclosures, or in the case of sensitive Personal Data, where you have opted-in if the Data Privacy Framework requires consent. We enter into written contracts with any unaffiliated third-party data controllers requiring them to provide the same level of protection for Personal Data the Data Privacy Framework requires. We also limit their use of your Personal Data so that it is consistent with any consent you have provided and with the notices you have received.
