About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role: When you see what modern language models are capable of, do you wonder, "How do these things work? How can we trust them?" The Interpretability team at Anthropic is working to reverse-engineer how trained models work because we believe that a mechanistic understanding is the most robust way to make advanced systems safe. Think of us as doing "neuroscience" of neural networks using "microscopes" we build - or reverse-engineering neural networks like binary programs. More resources to learn about our work: Our research blog - covering advances including Monosemantic Features and Circuits An Introduction to Interpretability from our research lead, Chris Olah The Urgency of Interpretability from CEO Dario Amodei Engineering Challenges Scaling Interpretability - directly relevant to this role 60 Minutes segment - Around 8:07, see a demo of tooling our team built New Yorker article - what it's like to work on one of AI's hardest open problems Even if you haven’t worked on interpretability before, the infrastructure expertise is similar to what's needed across the lifecycle of a production language model: Pretraining: Training dictionary learning models looks a lot like model pretraining - creating stable, performant training jobs for massively parameterized models across thousands of chips Inference: Interp runs a customized inference stack. Day-to-day analysis requires services that allow editing a model's internal activations mid-forward-pass - for example, adding a "steering vector" Performance: Like all LLM work, we push up against the limits of hardware and software. Rather than squeezing the last 0.1%, we are foc

About Vercel: Vercel is the agentic infrastructure company, freeing people and agents to ship what's next. For more than a decade we've helped builders move from idea to production with speed, security, and exceptional developer experience. Now we're scaling our products for both agents and people to ship and run software, built in the open and trusted by OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwide. About the Role: You’ll lead the team responsible for Vercel’s CDN, proxy, and edge caching systems—the core infrastructure that powers performance, reliability, and cost efficiency for every customer request at Vercel. Your mandate is twofold: Operate critical systems exceptionally (latency, reliability, COGS), and align the team to product and business goals, translating strategy into a clear roadmap You will set direction, grow people, and create the conditions for high trust, high autonomy, and high output—balancing technical depth with strong people leadership. This is a manager role, not a principal IC role. You’ll code when it’s the highest leverage (e.g., prototypes/unblocking), but your default is delegation, coaching, and alignment. About You: 8+ years building and operating large-scale distributed systems 3+ years managing engineers (managing managers is a plus) Demonstrated success leading CDN/proxy/caching/edge or similar high-throughput, low-latency infrastructure Proven ability to translate business goals into technical strategy and drive cross-org alignment Track record establishing trust, psychological safety, and clear expectations; skilled at timely, candid feedback Strong facilitator in technical conflict—you listen, synthesize, decide, and bring the team with you Competence across HTTP, TLS, caching strategies, load shedding, capacity planning, observability, and cost optimization Bonus If You: Have experience with Go, Lua, or Node at the edge; running high-signal hiring pipelines Collaborating with product/PMM on cus
