Exceptional Software Engineer (London)
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. All engineers are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.
About the team
You may work across the entire xAI tech stack ranging from model development to production infrastructure. This position is based in London, UK, and we will match you to a specific team at the offer stage.
About the role
Not every candidate fits neatly into our typical job postings. For instance, you might have built embedded systems for spacecraft rather than large-scale distributed infrastructure—but we’ve seen time and again that engineers who excel deeply in one hard domain tend to excel in others.
At xAI, our core work is training frontier AI models and shipping products built on them. Even if you have zero background in machine learning or consumer/infrastructure software, we strongly encourage you to apply if you’re confident you can have outsized impact here. Your previous industry or tech stack is irrelevant; what matters is a clear, demonstrated history of exceptional achievement—whether that’s debugging a mission-critical issue under impossible deadlines, turning around a failing project or company, or accomplishing something widely considered unfeasible.
The “statement of exceptional work” section below is the most important part of your application. Please invest extra effort: be concise, specific, and concrete.
