Senior Frontend Engineer - Autonomous Agents - Starfleet

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.

The Starfleet team builds the systems that power xAI’s next leap—self-driven AI that thinks, acts, and learns. We’re small, cross-functional, and laser-focused on delivering tools that researchers and agents alike can’t live without.

In this role you might:

• Craft slick, high-performance frontends in React/Typescript to control and monitor autonomous agents.
• Design intuitive UIs that make complex data (agent outputs, model insights) a breeze to navigate.
• Collaborate with full-stack and AI teams to ship end-to-end features that accelerate our mission.
• Push the boundaries of real-time, data-rich interfaces powered by unlimited GPU muscle.
• Innovate tools that bring us closer to AI that truly understands the universe.

Exceptional candidates may have:

• Delivered standout UIs in a fast-paced startup - as a tech lead, former founder, etc.
• Wrestled with data-heavy apps or real-time systems and won.
• Dabbled in Python or systems design—enough to talk shop with backend crews.
• Typescript, Python, Rust

The role is based in the Bay Area [San Francisco and Palo Alto]. Candidates are expected to be located near the Bay Area or open to relocation.

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 a 15-minute interview (“phone interview”) 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 technical interviews:

• Coding assessment in a language of your choice.
• Front end technical interview, in React/Typescript
• Systems hands-on:
  Demonstrate practical skills in a live problem-solving session.
• Meet the Team:
  Present your past exceptional work and your vision with xAI to a small audience.

Our goal is to finish the main process within one week. All interviews will be conducted via Google Meet.

Base salary is just one part of our total rewards package at xAI, which also includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, and various other discounts and perks.
