Magerman spent two decades working for James Simons’s New York-based investment management company Renaissance Technologies, where he developed trading algorithms.{{cite news |last=Fiorello |first=Victor |date=8 May 2017 |title=David Magerman Sues Breitbart Billionaire and Donald Trump Pal Bob Mercer|url=https://www.phillymag.com/news/2017/05/08/robert-mercer-lawsuit-breitbart-david-magerman/#EEE3dHLXwKRXumst.99 |work=Philly Magazine |location=Philadelphia, PA |access-date=8 May 2017 }} In 2017, Magerman publicly opposed the views of his boss, Robert Mercer, concerning politics and race issues in America. Mercer, the co-CEO of Renaissance Technology, suspended Magerman without pay and later made the suspension permanent. That same year Magerman filed a federal lawsuit against Mercer, seeking an excess of $150,000 in damages over alleged racist comments and unlawful termination.{{cite news|url=https://www.bloomberg.com/news/articles/2017-05-08/trump-backer-mercer-sued-by-employee-fired-after-speaking-out|title=Mercer Sued by Hedge Fund Worker Fired After Blasting Trump|newspaper=Bloomberg.com|date=8 May 2017|publisher=|via=www.bloomberg.com}}

In order to maintain the Jewish community in his neighborhood, Magerman has worked on several business ventures. His first of these was Citron and Rose, an upscale kosher certified meat restaurant, with Michael Solomonov as the head chef. After seeing little to no benefit of an upscale dining experience, Magerman re-branded the establishment as C&R Kitchen, and split with head chef Solomonov.{{cite web|url=http://www.phillymag.com/property/2013/04/29/citron-rose-owner-split-with-michael-solomonov/|title=Citron & Rose Owner Explains Split from Michael Solomonov|date=29 April 2013|publisher=}} During this time, he opened a casual dairy restaurant across the street. To better serve the community, C&R Kitchen was closed and replaced with a more fast casual place, The Dairy Express, known for its high capacity pizza oven. However, both of these restaurants have closed, and Citron & Rose became, C&R the Tavern. Zagafen, a restaurant that was attempted to mimic the non-kosher, ZaVino, was also opened.{{cite web|url=http://www.philly.com/philly/blogs/the-insider/The-New-Tavern-in-Bala-Cynwyd-closes-Main-Line.html|title=The New Tavern, a Main Line landmark, is closed; will become kosher restaurant and market|publisher=}}

Since founding The Kohelet Foundation in 2009, Magerman has donated tens of millions of dollars to local causes.{{Cite web|title=Meet David Magerman|url=https://www.ou.org/philanthropy/stories/meet-david-magerman/|website=philanthropy|language=en|access-date=2020-04-30}} Some of these include Kohelet Yeshiva High School (renamed from Stern Hebrew High School in the gift's honor), Yeshiva University and the Yeshiva Lab School.

In 2020, Magerman became a financial and vocal supporter of First Generation Investors, a 501(c)3 nonprofit organization that teaches high school students in underserved communities the power of investing and provides the students with real money to invest. He guest spoke to its students during a [https://www.linkedin.com/feed/update/urn:li:activity:6689691704448172032 virtual webinar in July 2020].{{Cite web|title=First Generation Investors posted on LinkedIn|url=https://www.linkedin.com/posts/firstgenerationinvestors_fgi-firstgenerationinvestors-investing-activity-6689691704448172032-iXza|access-date=2020-08-28|website=www.linkedin.com|language=en}}

In 2023, Magerman changed the name of The Kohelet Foundation to The Tzemach David Foundation. He did this because he did not want to be mistaken with an NGO with the same name that backed the Israel government’s judicial reform effort.{{Cite web|title=American donor giving $5m to Israeli colleges after spurning Penn|url=https://worldisraelnews.com/american-donor-giving-5m-to-israeli-colleges-after-spurning-penn/|first=Etgar|last=Lefkovits|date=June 27, 2024|access-date=July 4, 2024|website=WIN World Israel News}}

In 2024, Magerman pledged five million dollars to higher education institutions in Israel. He decided to stop supporting his alma mater, the University of Pennsylvania, over the administration’s handling of antisemitism on campus after the October 7, 2023 Hamas massacre in Israel.

Magerman provided the initial funds for the campaign group "Freedom from Facebook", donating $425,000 as of late 2018.{{cite web |last1=McCabe |first1=David |title=Scoop: The millionaire funding the campaign to break up Facebook |url=https://www.axios.com/david-magerman-campaign-break-up-facebook-82ba9228-34d9-4905-ab8d-2e44e30822a6.html |website=Axios |date=15 November 2018 |accessdate=16 November 2018 |language=en}}
