Senior Customer Support Systems Administrator

Mercury · San Francisco, CA, New York, NY, Portland, OR, or Remote within Canada or United States

Mercury, a company in the financial technology space, is seeking a Senior Customer Support Systems Administrator to maintain and evolve its Zendesk‑based support infrastructure. Day‑to‑day responsibilities include administering the Zendesk platform, monitoring performance, applying security patches, and generating usage reports to guide service improvements. The role also involves coordinating with other systems such as WFM, QA, Notion, Guru, Slack and Okta, identifying automation opportunities—particularly AI‑driven workflows—and documenting processes to support upcoming regulatory requirements as the firm pursues a bank charter. Collaboration is key: the administrator will act as the technical expert for ad‑hoc support requests, train agents, partner with engineering and business teams on change control, and contribute to continuous‑improvement initiatives. The position suits candidates with three to five years of hands‑on Zendesk administration experience, solid troubleshooting abilities, familiarity with cloud‑based security and monitoring tools, and an interest in integrating support systems across a broader tech stack.
