Seaman has worked in the Israeli civil service for 31 years (1983-2014). Between 2000-2010, he served as the director of the Israeli Government Press Office (GPO), part of the Prime Minister's Office in Jerusalem responsible for the foreign media contingent in Israel. His last position was Deputy Director General for Information at the Israeli Ministry of Public Diplomacy and Diaspora Affairs. In August 2013, Seaman was suspended from his government position as Director of Interactive Media because of comments he made in a private Facebook posting about Japanese commemorating the bombing of Hiroshima and Nagasaki and Palestinians commemorating the Nakba. In January 2014 Seaman retired from his position.
Seaman was the bureau chief of Voice of Israel, a private Israeli English-language news and talk internet radio station that was created in 2014 and closed due to a lack of funding in 2015. Seaman hosted In The Lions' Den with Daniel Seaman and Daniela Traub interviewing such guests as Dr. Einat Wilf, Zvi Yehezkeli, Ehud Gol, Col. Richard Kemp, Dr. Joy Browne, Bassem Eid and other political and media figures.
Seaman was born on a US Air Force base in Germany, the son of an American father and a mother born in Israel. His family moved from the United States to Israel in 1971 and settled in the port city of Ashkelon.
Seaman was directly responsible for coordinating the press coverage of several heads of states visits to Israel including US President Bill Clinton, British prime minister Tony Blair, Canadian prime minister Jean Chrétien, Australian prime minister John Howard, Jordan's King Hussein and Chinese president Jiang Zemin. He was a member of the Israeli press delegation to the Aqaba peace talks (see Road map for peace, Red Sea Summit in Aqaba, Jordan, June 4, 2003). Seaman received the Israel Outstanding Civil Service Award in 2000 for coordinating the international press coverage of Pope John Paul II's visit to the Holy Land in March 2000.
Seaman was appointed as acting director of the Government Press Office (GPO) in December 2000 and worked with thousands of foreign journalists who covered news events in Israel and the Palestinian territories until 2010. He had worked for the GPO for several years and was the first civil servant promoted to directorship of the GPO after a period of 30 years. During his tenure as GPO director he implemented several measures that improved working conditions for foreign journalists in Israel. This notwithstanding, there were numerous complaints about his treatment of journalists unsympathetic to Israeli policies (see Controversies below).
Seaman lectures on Israeli and Middle-Eastern affairs and appeared on dozens of international news media outlets.
Seaman on coverage of the Israel-Palestinian conflict
Seaman is said to have observed the a dramatic intensification of public diplomacy in coverage of the Israeli-Palestinian conflict, what interviewers have called "cognitive warfare" waged in a "battlefront of perceptions", in which Israel must handle a "global media battle". Israel is, he adds, suffering "strategic damage" from this area. In this, he sees the media as "agenda-driven" concerning the Palestinian narrative and Palestinian society highly mobilized, and these two elements cause Israel's image to suffer in international reportage. The problem is, he argues, that the Arab world fails to maintain journalistic standards accepted in the West, and in waging their media war insult the free press tradition which, he affirms, Israel upholds. Critics claim that his demand for stricter standards is damaging media relations. 
Regarding journalists involved in covering the conflict he has stated:
I don't work with journalists directly anymore and it's a huge relief. They disregard the laws of the country, they don't respect boundaries in Israel in ways they wouldn't dare in other countries. . They're insulted when they have to go through regular security checks like everyone else .. and sometimes the journalists knowingly assist enemies of the state..'
Journalists must prove their credentials. Activists, he says, should not be described as something they are not, journalists. Israelis when hurt return to a normal life quickly, whereas Palestinians exploit their tragedies as weapons in a media battle. The effect is to impress world opinion with the idea that Palestinians suffer more than do Israelis. The Israeli media also have problems, with, he calculates, 90% of media reflecting what is only 5% of Israeli public opinion. He is critical of the vocal exposure of the multiplicity of voices in Israel in lieu of a "centralization across all sectors" that would permit Israel to deploy a formidable "unified force of opinion".
In Operation Cast Lead, Israel blocked foreign journalists from entering the Gaza Strip to report on the war. This raised an outcry of protest, with UNWRA claiming that failure of access by journalists hindered a truthful representation of what was occurring. The reason given by the Israeli government for its ban was that international correspondents would be endangered there, and that to protect them, Israel would have to divert resources towards their protection better spent on fighting Hamas. Seaman was quoted on CNN as saying that Israel had learnt a lesson from its war with Hezbollah in Lebanon earlier in 2006:'There was too much exposure, it had an effect on our ability to achieve strategic goals’, a declaration taken to indicate the real rationale behind the government's ban. Seaman was also quoted by the New York Times's Ethan Bronner as arguing: 'Any journalist who enters Gaza becomes a fig leaf and front for the Hamas terror organization, and I see no reason we should help that.' The Goldstone Report on the war added that Seaman also expressed the view that foreign correspondents lacked professionalism and took "questionable reports at face value without checking".
Conflicts with journalists
As the director of the GPO, Seaman came under criticism for not issuing journalists with Israeli press cards. Additionally, he was accused by one journalist of becoming aggressive, abusive and using foul language against journalists he considered hostile and unfair towards Israel. Such journalists included Israeli mainstream media employees such as Atta Awisat, a veteran staff photographer at Yedioth Ahronoth, then the largest newspaper in Israel, allegedly due to clearance issues with the security agencies.
Seaman did not deny using this type of policy towards blatantly anti-Israeli media outlets:
"I can make journalists’ lives more difficult. There are certain guidelines that allow me to do that. Such as with the case of [Swedish newspaper] Aftonbladet, and their despicable anti-Semitic [...] report on the IDF [purportedly] abducting Palestinians and using their body organs. We didn’t prevent Aftonbladet from working here. We just took our time. To this day, the correspondents from Aftonbladet do not get a press card immediately. We can take up to 90 days and we can take longer..."
Another journalist who became the target of Seaman's contempt was Jörg Bremer, a 15-year veteran of the press corps in Jerusalem, who worked as the correspondent of the right-liberal German Frankfurter Allgemeine Zeitung newspaper. In his case, he was denied not the renewal of his press card, but the extension of his residence visa. For calling this measure a political way of keeping unwanted journalist at bay and for asking for the German government's support, Bremer was described by Seaman in a newspaper interview as "an idiot," "a piece of shit" and "a miserable liar." Bremer said in response that "Seaman wants journalists to lick his feet. He gets enjoyment from the situation, and uses his power instead of helping. It is harmful to Israel."
On 11 March 2007, Haaretz reported that the Israeli Civil Service Commission was investigating foreign journalists' accusations that Government Press Office director Daniel Seaman has treated them improperly and enforced the procedures for receiving a press pass in an inequitable manner.
In August 2013, Haaretz accused him of having "gained a reputation for his confrontations with foreign correspondents and for the complaints they lodged against him" and called him "an abusive racist." The article, included selected quotes from Seaman’s personal Facebook page. Seaman was admonished by the government, which distanced itself from his views and then suspended him from his position as Director of Interactive Media because of offensive, racist comments.
Comments against Japanese nuclear victim commemorations
— "I am sick of the Japanese, 'Human Rights' and 'Peace' groups the world over holding their annual self-righteous commemorations for the Hiroshima and Nagasaki victims. Hiroshima and Nagasaki were the consequence of Japanese aggression. You reap what you sow. Instead, they should be commemorating the estimated 50 million Chinese, Korean, Filipino, Malay, Vietnamese, Cambodian, Indonesian, Burmese and other victims of Japanese imperial aggression and genocide." The statement, posted on Seaman's personal Facebook page, lead to a rebuke from the Japanese government and an official Israeli apology. Editorials in Tablet and Israel National News called Seaman's supension over the incident "misguided."
