The Position The City of Oakland is an equal opportunity employer that values workforce diversity, inclusion, and equity. Oakland has a long history of activism around issues of justice and equity. Both oppression and this resistance to oppression have shaped the city's historical roots and the lives of its residents to this day.

As public servants in one of the most diverse cities in the nation, we strive to develop employees who understand the harm and impacts of systemic inequity to create lasting, meaningful outcomes for everyone. Oakland strives to establish an environment that embraces the richness of culture, community, and individualism of employees. Why join the City of Oakland.

The City of Oakland is currently recruiting to fill multiple Assistant Engineer II (Office) vacancies in the Department of Transportation (OakDOT). This classification is also used in Oakland Public Works (OPW) and the Planning and Building Department (PBD), but there are currently no vacancies in these departments. Candidates may be referred to an interview with one or more teams or departments that have a vacancy as part of the continuous eligibility list.

The following section describes the various departments/teams and their functions within the City.
