X Engineer YacineMTB Announces Termination, Citing Uncertainty Over Reasons

San Francisco, CA – YacineMTB, known on social media as "kache" and formerly a staff engineer at X (formerly Twitter), announced his termination from the company on June 21, 2025. In a tweet that quickly gained traction, YacineMTB stated, > "I got fired today. I'm not sure why, I personally don't think there is a reason, or that it's important." This public declaration has sparked discussions regarding employee relations and transparency within the social media giant.

YacineMTB, whose real name is Yacine Abdi, previously held a staff engineer position at X. His social media presence often included technical insights and, at times, controversial commentary. Prior to his tenure at X, he was associated with Stripe, where he gained experience in scaling organizations and software systems.

The engineer's departure follows a period of notable personnel changes and shifts in company culture at X since its acquisition by Elon Musk. While the specific reasons for YacineMTB's termination remain undisclosed by the company, his tweet indicates a lack of clear explanation provided to him directly. His past online interactions, including a December 2024 incident where Elon Musk defended him against accusations of racism, have occasionally drawn public attention to his employment.

YacineMTB's statement reflects a sentiment of uncertainty, contrasting with the initial appeal he found in the company's engineering environment. He noted upon joining, "When I joined twitter, I joined because of the engineers I met in SF. They seemed happy. They were having fun. Engineers at play. Engineers that were enabled. It was good!" This recent development underscores the ongoing evolution of X's internal dynamics and its impact on its workforce.
