Deputy Chief of Staff Job Description

A Deputy Chief of Staff is the operating officer of an executive's inner office. The principal might be a mayor, a county executive, a governor, a member of Congress or the head of a federal department. The chief of staff decides what the principal sees and who gets time on the calendar; the deputy makes sure the rest of the office actually delivers on those decisions, every day, across every team.

City classification specs describe the job in concrete terms. Chattanooga's specification, revised in October 2023, says incumbents carry "oversight responsibility for specific portfolio areas as assigned by the Chief of Staff," including supervision of communications and public relations staff. The same document has the deputy serve on the chief of staff's top management planning and decision team, coordinate the portfolio's operating and capital budgets, and represent the city before state and federal agencies. That mix of internal management and outside representation is the core of the role.

At the federal level, agency front offices belong to the world catalogued in the Plum Book, the congressional list of leadership and support positions published after each presidential election. The 2024 edition, with data as of July 16, 2024, covers over 7,000 positions that may be filled by noncompetitive appointment, including "aides who report to these officials," and its foreword notes that incumbents usually have a close and confidential working relationship with the agency head or other key officials. Trust, rather than a civil service ranking, is what puts a person in the chair.

A typical day bounces between three kinds of work. First, traffic control: reading the overnight email, sorting what needs the chief or the principal, and pushing everything else back to the right director with a deadline. Second, product review: editing a decision memo from the policy shop, tightening remarks for a ribbon cutting, checking that the numbers in a budget briefing match what the finance office sent. Third, people: settling a turf fight between communications and scheduling, coaching a new legislative aide, or sitting in on an interview for a constituent services hire.

The portfolio defines the job. Some deputies own operations and administration, which means budgets, personnel, facilities and records. Others own policy, intergovernmental affairs or external relations, and spend their time with legislators, agency heads, unions, business groups and neighborhood associations. In a congressional office, the deputy may run the Washington office while a district director handles casework back home. In a governor's office, separate deputies may cover policy, operations and political affairs at once.

What stays constant is the vantage point. The deputy sees almost everything that flows to the principal, knows which commitments have been made and to whom, and is often the person who has to say no on the chief's behalf. Done well, the position is invisible: meetings start prepared, deadlines are met, and nothing reaches the press that the office did not intend.

There is no professional license for this job. Governments hire deputy chiefs of staff on judgment, trust and a record of getting things done for a principal. Where a deputy post is exempt from civil service rules, hiring is at the discretion of the elected official or agency head.

Where a written standard exists, it tends to be broad. Chattanooga's classification asks for 14 years of any combination of relevant education, training or experience, names a bachelor's degree in public or business administration, political science or a related field as an example of relevant education, and lists a master's degree as preferred. It also asks for progressively responsible leadership and management experience directing administrative, technical and professional staff, and requires employees to maintain Tennessee residency from the date of hire.

Education. As a rough guide, a bachelor's degree is the usual starting point, often in political science, public policy, public administration, economics, communications or history. A master of public administration or public policy helps in agency and city management roles, and a law degree can help deputies who own legal, regulatory or legislative portfolios. None of these is a substitute for time spent inside a government office.

Experience. As a rough guide, expect five to ten years in government, campaigns, advocacy or public affairs before a deputy chief of staff offer, with at least one job that involved managing other staff. Typical prior titles include legislative director, policy director, communications director, deputy campaign manager and senior adviser to an agency head. Local government deputies sometimes arrive from city management, budget or neighborhood services work.

Skills that matter on day one:

• Clean, fast writing: decision memos, briefing notes, talking points and letters that a principal can read in two minutes.
• Budget literacy: reading an operating and capital budget, spotting where a portfolio is overspent, and explaining it to an elected official.
• Process knowledge: how a bill moves, how a council agenda is set, how rulemaking or procurement works in that jurisdiction.
• Discretion: personnel files, legal advice and political strategy cross the desk daily.
• People management under pressure: keeping a young, overworked staff productive through session deadlines and crises.

Credentials. None are required. The ICMA Credentialed Manager designation from the International City/County Management Association is a voluntary credential for professional local government managers; ICMA limits eligibility to local government chief administrative officers and assistant chief administrative officers, so it applies only to deputies in those roles. Federal deputies who come from career service bring their agency training; political appointees learn the ethics and records rules in onboarding.

BLS publishes no employment count or projection for deputy chiefs of staff. The job is folded into broader management occupations, and openings follow elections, appointments, resignations and reorganizations. A new mayor, a new governor or a new cabinet secretary can rebuild the senior staff soon after taking office.

Congressional offices have their own pay data for the title. In its July 2025 report on House member offices, the Congressional Research Service put the 2024 median for a deputy chief of staff at $138,717, in constant 2025 dollars, up 3.32% from 2023. Its companion report on Senators' offices put the FY2024 median at $183,264, down 3.58% from the year before.

Federal personnel rules shifted in 2025. Executive Order 14317, signed July 17, 2025, created Schedule G in the excepted service, and OPM's July 29, 2025 guidance to agencies says no excepted service schedule had existed specifically for noncareer positions of a policy-making or policy-advocating character. For deputies in agency front offices, that adds a second noncareer hiring route alongside Schedule C, and it is worth knowing which schedule an offer letter names before accepting.

Technology is the other change landing on the desk. In April 22, 2026 testimony to the Senate appropriations subcommittee on the legislative branch, the Sergeant at Arms and Doorkeeper of the Senate said her office had issued an AI policy for the Senate at the start of the fiscal year and set up an AI Governance Board for oversight and risk management. The same testimony asked for an increase of $2,800,000 to fund AI licenses for Senate users beyond FY 2026; at the time, that was a budget request, not an appropriation. For a deputy chief of staff, sanctioned tools mean a new set of office rules to write: what may be pasted into a chatbot, how drafts are reviewed, and how AI-assisted documents fit records and disclosure requirements.

The judgment calls stay with people. Deciding which issue reaches the principal today, which ally needs a call before an announcement, and which staffer is ready for more responsibility depends on relationships and judgment that a drafting tool does not have.

Exit paths are wide. Former deputies can move up to chief of staff, take agency leadership posts, run campaigns, join lobbying and government relations firms, lead trade associations and nonprofits, or run for office. The main risk is dependence on a single principal: a lost election, a scandal or a resignation can end the job overnight. A deputy who keeps relationships across offices and parties, and who leaves a record of well-run operations, keeps the next move open.

Dear Chief of Staff Alvarez,

Please consider me for the Office of the Mayor's opening for a Deputy Chief of Staff. For the past four years I have served as policy director to Councilmember Dana Whitfield, and before that I spent three years as a legislative aide in the state senate. I am ready to run the operational side of a larger office and to take work off your desk, not add to it.

In my current role I manage a team of five covering housing, transportation and public safety. I set the weekly priorities, edit every memo before it reaches the councilmember, and keep a running tracker of the commitments she has made to residents, unions and business groups. When the council took up the transit levy last spring, I coordinated our office's work with the budget office, two community coalitions and the mayor's intergovernmental team, and I briefed the councilmember daily during the final two weeks of negotiations.

I also handle the unglamorous work that keeps an office credible: records requests, ethics filings, onboarding for new staff, and the first read on anything with legal exposure. Last year I wrote our office's guidelines for using drafting software with constituent data, which the council clerk later shared with other offices.

What I would bring to the mayor's office is steady management of people and deadlines, fluency in the city's budget process, and the judgment to know which decisions belong with you and the mayor and which I should simply handle. I would welcome the chance to talk about the portfolio you have in mind for this role.

Sincerely,

Jordan Reyes
