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 and researchers are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

About the Team

You will work on the team responsible for the frontend services that power grok.com and our API. Our team is distributed across London and Palo Alto. We focus on implementing highly performant user interfaces that are delightful to use. We primarily use React with NextJS for rendering.

About the Role

An ideal candidate meets the following requirements:

• Expert knowledge of TypeScript and React,
• Expert knowledge of Tailwind,
• Expert knowledge of best practices regarding performance, accessibility, and frontend security.

Additionally, any of the following qualifications may help a candidate stand out:

Location

We hire engineers in London and Palo Alto. We usually work from the office 5 days a week but allow for work-from-home days when required. Candidates joining the London team must be willing to attend late meetings at least once a week to coordinate with the rest of our team.

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 phone interview during which a team member will ask some basic technical questions. If you clear the initial phone interview, you will proceed to two technical interviews:

• Coding interview in TypeScript: Write a small app in React
• HTML/CSS interview: Given a screenshot of a UI, implement it

All interviews will be conducted via Google Meet.
