After school, Tuckman's first job was six years as an assistant professor of finance for New York University's Stern School of Business (NYU Stern).
Tuckman began his career on Wall Street in 1994 as a senior researcher focused on fixed income arbitrage trading for Salomon Brothers before becoming head of U.S. fixed income derivatives research and a managing director.
In 1999, Tuckman joined Credit Suisse First Boston where he focused on a variety of endeavors including fixed income proprietary trading, credit characteristics of mortgages and relative value modeling of a wide variety of markets. 
Tuckman's next stop on Wall Street was eight years with Lehman Brothers (later Barclays Capital) as a managing director heading up rates and foreign exchange modeling. While at Lehman he created FEDISCOPE, a tool which derived implied probabilities for Federal Reserve rate decisions, and also the Futures Calculator, an analytical tool for scenario analysis for fixed income futures. Later, he was responsible for a wide swath of risk management duties, and developed an award-winning portfolio margining tool.
Next, Tuckman went to the Center for Financial Stability (CFS) as director of financial markets research in 2010. After two years with the CFS, Tuckman returned to NYU Stern as a full professor. He taught three classes at NYU, "Debt Instruments and Markets" and two new programs, "Trading in Cash and Derivative Securities" and "Liquidity Risk Management."
In a Washington Post article from 2013, Tuckman is referenced as saying the financial system is so complicated that "a whole control room of indicators wouldn’t suffice to understand it."
Tuckman graduated from Harvard with an Bachelor of Arts degree in statistics in 1984. He then went to the Massachusetts Institute of Technology where he graduated with a Ph.D. in economics in 1987.
