Early life and career Mosqueda was born in Olympia, Washington, and is of third-generation Mexican descent on her father's side and Polish/Swedish/Norwegian on her mother's.

Seattle City Council Elections In 2017, Mosqueda ran for the open at-large District 8 position on the Seattle city council after incumbent Tim Burgess announced he would not seek reelection, later becoming interim mayor of Seattle.
In the November general election, Mosqueda defeated Grant, 60% to 40%.
In 2021, Mosqueda announced that she would seek reelection and not run in the Mayor election. She faced ten challengers in the primary election, significantly outraising all of them and received more endorsements from elected leaders and labor unions. In the August primary election, Mosqueda came in first with 59% of the vote, and structural engineer Kenneth Wilson also advancing to the general with 16% of the vote. Mosqueda focused her campaign on addressing economic inequalities in Seattle, while Wilson focused on fixing major infrastructure like bridges.

Tenure In her first year on council, Mosqueda passed legislation to protect domestic workers and voted no on repealing the controversial Seattle head tax, which was meant to build affordable housing and pay for homelessness services. During her first term she also led the push legislation that would give parents access to paid family leave care benefits after the death of a child and if a partner dies during childbirth. Mosqueda was the prime sponsor of the JumpStart tax, which is a payroll tax on large businesses and funds affordable housing and Green New Deal policies.
During the 2020 George Floyd protests, Mosqueda, as budget chair, called for a "full, thorough, simultaneous deep dive" into the Seattle Police budget. She also called for 50% cuts into the police budget and reinvest the money into the community.
Mosqueda remained budget chair in her second term during the 2023-24 budget process, with a $141 million deficit and an $82 million revenue shortfall.
