内容总结：

近期，全球科技巨头间高管流动频繁，人工智能与数据领域的人才竞争尤为激烈。前亚马逊AI战略核心人物卡西克·拉马克里希南已正式加入谷歌云，担任数据云部门副总裁。拉马克里希南在亚马逊任职14年间，曾主导Alexa智能助手的推出及Nova基础模型的研发，其职业轨迹贯穿“从对话式AI到多模态通用人工智能的完整演进”。他在领英上表示，将专注于助力谷歌云团队“构建未来的自主数据平台”，迎接“智能体时代”的到来。

与此同时，亚马逊人工智能业务高层持续调整。上月，原AI项目负责人罗希特·普拉萨德已离职。亚马逊CEO安迪·贾西于12月17日宣布，由司龄27年的云基础设施高管彼得·德桑蒂斯统领新整合的团队，统筹Nova模型研发、定制芯片及量子计算业务。在近期re:Invent大会上，亚马逊发布了Nova 2模型，正加速追赶OpenAI、谷歌等AI领域竞争者。

另一则重要人事变动来自微软：原公司副总裁、首席法律高管C.J.马奥尼已转投Meta，出任首席法律官。马奥尼在微软任职五年，曾主管国际贸易、Azure及产品市场化的法务工作，更早前曾任美国副贸易代表。其职位空缺由微软资深高管乔纳森·帕尔默接替，而Meta原首席法律官詹妮弗·纽斯特德则已赴苹果任职。

这一系列高层变动折射出全球科技行业在人工智能、云计算及法律合规等关键领域的战略布局与资源重组已进入白热化阶段。

上月，曾领导亚马逊人工智能战略并监督自研Nova AI模型开发的高管罗希特·普拉萨德已离职。亚马逊首席执行官安迪·贾西在12月17日的内部备忘录中宣布，由在公司任职27年的云基础设施资深高管彼得·德桑蒂斯统领新成立的机构，该机构将整合Nova模型研发团队、定制芯片及量子计算业务。在11月举办的年度re:Invent大会上，亚马逊发布了Nova 2模型系列。该公司正试图在开发高性能人工智能系统的竞赛中缩小与OpenAI、谷歌等竞争对手的差距。

— 微软公司副总裁兼首席法务官C·J·马奥尼已转投Meta担任首席法务官。该消息由Axios率先报道。过去五年间，马奥尼先后担任微软负责国际贸易与Azure业务的副首席法务官，以及主管产品、服务与市场推广法务的公司副总裁兼总法律顾问。2018至2020年特朗普首届总统任期内，他曾担任美国副贸易代表。马奥尼接替了转投苹果担任总法律顾问的珍妮弗·纽斯特德。今年9月，在原首席法务官侯赛因·诺巴尔（现任ServiceNow总裁兼首席法务官）离职后，微软提拔资深高管乔纳森·帕尔默接任该职务。

— Karthik Ramakrishnan, who spent the past 14 years at Amazon where he helped develop the company’s AI strategy, has taken a VP role within the Data Cloud organization at Google Cloud.
“We are entering the ‘Agentic Era,’ and my focus is helping this world-class team build the autonomous data platform of the future,” Ramakrishnan wrote on LinkedIn. “I can’t wait to dive back into the ‘hard things’ and see what we can build together next.”
Ramakrishnan helped launch Amazon Alexa and develop the Amazon Nova foundation models. “My work at Amazon spanned the full evolution from conversational AI to multi-modal AGI,” he notes on his LinkedIn profile. Before joining Amazon in 2012, Ramakrishnan spent three years at Microsoft following the company’s acquisition of Tellme Networks, where he was a senior platform engineer. He started at Google in September.
Last month, Rohit Prasad, the executive who led Amazon’s AI initiatives and overseen the creation of its homegrown Nova AI models, left the Seattle-based company.
In a memo sent Dec. 17, Amazon CEO Andy Jassy named Peter DeSantis, a 27-year company veteran and top cloud infrastructure executive, to lead a new organization that combines its Nova and model research teams with custom silicon and quantum computing.
Amazon last month unveiled its Nova 2 models at its annual re:Invent conference. The company is attempting to close the gap with AI rivals including OpenAI and Google in the race to develop increasingly capable AI systems.
— C.J. Mahoney, a corporate vice president and top legal executive at Microsoft, joined Meta as its new chief legal officer. Axios first reported the move.
Mahoney spent the past five years at Microsoft, first as a deputy general counsel focused on international trade and Azure, then later as a corporate vice president and general counsel for product, services, and go-to-market legal. He previously was a deputy U.S. trade representative from 2018 to 2020 during President Trump’s first term.
Mahoney replaces Jennifer Newstead, who departed for the general counsel role at Apple.
Microsoft promoted longtime exec Jonathan Palmer to chief legal officer in September, following the departure of Hossein Nowbar, who is at ServiceNow as president and chief legal officer.
