We're building a new kind of infrastructure that supports orchestrating complex agents, running evals, and putting safety rails around probabilistic systems. This is fundamentally different from traditional software development, where the biggest skills gap isn't in model training or infrastructure but in AI Engineering: taking foundation models as a new addition to our toolkit, and using them to build reliable, real-world product. We're hiring AI Engineers who can apply this knowledge to ship world-class products that leverage probabilistic systems, user experience, product craft, and customer impact. Our team has already made significant internal shifts and built a world-class internal platform to support the use of AI, and we're actively building an agent that will investigate incidents, find out what's wrong and why it's wrong, and offer to fix them on behalf of responders.
