Role
Who you are

- Strong generalist who can fluidly move between UI/UX implementation, API design, data modeling, and systems architecture
- Proficient in modern web technologies (e.g., TypeScript/React/Next.js on the frontend; Python/FastAPI or similar on the backend)
- Solid experience with relational databases and designing schemas for complex domains
- Good eye for UX design and strong attention to detail
- Familiarity with large-scale user-facing applications or domain-specific platforms is a strong plus

- Build and maintain fullstack features, including user dashboards, personalized experiences, content delivery, interactive tools, assessments, and real-time analytics
- Develop backend services, APIs, and data models to support high-volume, multi-user environments
- Integrate AI capabilities (tutoring, content generation, personalization) deeply into the platform
- Design and implement database schemas and queries for tracking progress, engagement, and reporting
- Collaborate on integrations with external systems and data sources to enable comprehensive workflows
- Ensure the platform is performant, secure, reliable, and scalable for broad deployment
- Work closely with product, design, AI, and domain experts to iterate rapidly based on user feedback and outcome data
- Tech Stack:
- Primarily JavaScript/TypeScript and Python
- Frontend: React, Next.js
- Backend: FastAPI or Django
- Database: SQL, Redis
- Infrastructure: AWS/GCP, Docker, Kubernetes
- Other: REST/GraphQL APIs, real-time features (WebSockets), analytics pipelines
Application 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 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 2 technical interviews and 1 project deep-dive interview:
- Practical coding assessment in a language of your choice
- Systems design hands-on: Demonstrate practical skills in a live problem-solving session
- Project deep-dive: Present and answer questions about exceptional work that you’ve done
- Meet and greet with the wider team
- Our goal is to finish the main process within one week. Final interviews will be conducted in person
Our take
xAI is Elon Musk's venture into the world of artificial intelligence, and like all things Musk, it's going big. Its setting out to build AI that helps humanity understand the universe and its starting with Grok, its conversational AI chatbot already integrated into X (formerly Twitter). With access to real-time data and a powerful ecosystem of Musk-led companies, xAI is certainly pushing towards artificial general intelligence at serious scale.
Like all bold ventures, xAI has faced its share of controversy, from questions about regulation to the overlap across Musk's businesses. But fans are still seeing the bigger picture: an interconnected tech ecosystem where AI, social media, and space exploration feed into one another.
Recently, the company made headlines with its massive "Colossus" supercomputer project, powered by tens of thousands of Nvidia GPUs. While the data center's temporary power setup has faced environmental scrutiny, the scale of ambition is certainly undeniable. From launching tap-to-pay features on X to building one of the most powerful AI training systems on Earth, xAI is moving fast.
