Company mission
To build AI systems that can help humanity understand the world better.
Role
Who you are
- Has strong software engineering skills,
- Has a background in post-training or evaluating frontier AI systems
- Is a team player and willing to pick up new skills to get the job done
What the job involves
- XAI is seeking talented researchers and engineers to improve the safety of our AI systems and ensure that they are maximally beneficial for society
- In this role, you will work toward measuring and architecting the behavior of our frontier AI systems across a wide variety of safety-relevant areas such as truth-seeking and deception.
- You will work across all stages of the model development pipeline, from collaborating with legal and product teams to iterate on policy guidelines, building new benchmarks to quantify novel behaviors, running human data collection projects, experimenting with novel post-training and reasoning training recipes, and shipping product updates to millions of users around the world
- Candidates for this role may focus on one or more of the following:
- Ensure truth-seeking behavior by Grok even in adverse situations
- Measuring and steering Grok’s propensities for deception, sycophancy, and power-seeking
- Developing and enforcing clear, consistent policy guidelines across models and products
- Building ecologically valid benchmarks to assess agentic propensities and capabilities
- We hire engineers in Palo Alto. Our team usually works from the office 5 days a week but allow work-from-home days when required. Candidates are expected to be located near Palo Alto or open to relocation
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 four technical interviews:
- Coding assessment in a language of your choice
- Technical sessions (2): These sessions will be testing your ability to formulate, design and solve concrete problems in real world with LLM
- 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
Our take
SpaceXAI, formerly XAI, is Elon Musk's venture into the world of artificial intelligence, and like all things Musk, it's going big. It's setting out to build AI that helps humanity understand the universe, and it's 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, SpaceXAI is certainly pushing towards artificial general intelligence at serious scale.
Like all bold ventures, SpaceXAI has faced its share of controversy, from questions about regulation to the overlap across Musk's businesses (most recently, XAI became a subsidiary of the Musk-owned SpaceX). But fans are still seeing the bigger picture: an interconnected tech ecosystem where AI, social media, and space exploration feed into one another.
The company made headlines in 2024 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.
