About xAI
xAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands‑on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important.

Deployment Engineers will own all aspects of planning and building of green and brownfield network deployments. Operations Engineers will own timely mitigation of network impairments for all layers of our network and the return to service of Network HW and capacity. You will be expected to participate in a team on‑call rota and to contribute to scaling and maintenance efforts.

Interview Process
After submitting your application, the team reviews your CV and statement of exceptional work. If your application passes this stage, you will be invited to an initial interview (45 minutes – 1 hour) during which a member of our team will ask some basic questions. If you clear the initial phone interview, you will enter the main process, which consists of four interviews:
* Coding Interview
* Network Engineering technologies.
* Meet and greet with the team with a presentation of a large scale solution or problem you owned, start to finish.
Our goal is to finish the main process within one week. We don’t rely on recruiters for assessments. Every application is reviewed by a member of our technical team. All interviews will be conducted via Google Meet or in person.
