At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact , advancing our long-term goals of steerable, trustworthy AI , rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We’re an extremely collaborative group, and we host frequent research discussions</p>\n<p style=\"margin-top:24px;font-size:13px;color:#666;\">XML job scraping automation by <a href=\"https://yubhub.co\">YubHub</a></p>","url":"https://yubhub.co/jobs/job_d08d38d2-b72","directApply":true,"hiringOrganization":{"@type":"Organization","name":"Anthropic","sameAs":"https://www.anthropic.com/","logo":"https://logos.yubhub.co/anthropic.com.png"},"x-apply-url":"https://job-boards.greenhouse.io/anthropic/jobs/5159608008","x-work-arrangement":"hybrid","x-experience-level":"senior","x-job-type":"full-time","x-salary-range":"$320,000-$405,000 USD","x-skills-required":["software engineering","team management","platform ownership","service-to-other-teams","launch-driven operational rhythm","system design","pipeline architecture","product mindset","recruiting and closing senior ICs"],"x-skills-preferred":["LLM evals","ML experimentation platforms","model quality work","A/B testing infrastructure","feature flagging","gradual rollout systems","devtools","CI/CD platforms","testing infrastructure at scale"],"datePosted":"2026-04-18T15:54:35.018Z","jobLocation":{"@type":"Place","address":{"@type":"PostalAddress","addressLocality":"San Francisco, CA | New York City, NY"}},"employmentType":"FULL_TIME","occupationalCategory":"Engineering","industry":"Technology","skills":"software engineering, team management, platform ownership, service-to-other-teams, launch-driven operational rhythm, system design, pipeline architecture, product mindset, recruiting and closing senior ICs, LLM evals, ML experimentation platforms, model quality work, A/B testing infrastructure, feature flagging, gradual rollout systems, devtools, CI/CD platforms, testing infrastructure at scale","baseSalary":{"@type":"MonetaryAmount","currency":"USD","value":{"@type":"QuantitativeValue","minValue":320000,"maxValue":405000,"unitText":"YEAR"}}},{"@context":"https://schema.org","@type":"JobPosting","identifier":{"@type":"PropertyValue","name":"YubHub","value":"job_0806749e-694"},"title":"Engineering Manager, Agent Prompts & Evals","description":"<p><strong>About the Role</strong></p>\n<p>Anthropic is looking for an Engineering Manager to lead the Agent Prompts &amp; Evals team.

You don&#39;t need to hand off to engineering every time a prospect has a hard question — you can answer it yourself or build the proof on the spot.</p>\n<p><strong>An empathetic communicator who bridges worlds.</strong> You translate complex technical ideas into clear value for engineers and non-technical stakeholders alike. You know when to go deep on architecture and when to zoom out to business impact.</p>\n<p><strong>A problem solver, not a slide reader.</strong> You dig into customer workflows, understand blockers, and craft creative technical solutions. Your demos feel like conversations, not presentations.</p>\n<p><strong>Startup-ready and comfortable in ambiguity.</strong> You don&#39;t need a playbook or a solutions catalog. You thrive when the answer is &quot;figure it out,&quot; and you move fast enough that customers feel momentum.</p>\n<p><strong>Cross-functional glue.</strong> You work naturally across Sales, Product, and Engineering. You&#39;re the connective tissue between what customers need and what gets built.</p>\n<p><strong>Backgrounds that often do well:</strong> Sales engineers or solutions architects at devtools or API companies. Engineers who discovered they love the customer-facing side. Technical founders who&#39;ve sold their own product.</p>\n<p><strong>What We&#39;re NOT Looking For</strong></p>\n<p><strong>Demo jockeys who can&#39;t go off-script.</strong> If your comfort zone is a rehearsed slide deck and a scripted walkthrough, this isn&#39;t the role. Prospects will ask hard questions and you need to answer them live.</p>\n<p><strong>Non-technical &quot;relationship builders.&quot;</strong> Rapport matters, but you need to earn trust through technical depth. If you can&#39;t read code or debug an API call, you&#39;ll struggle here.</p>\n<p><strong>People who wait for the AE to set the agenda.</strong> You own the technical narrative in every deal. If you need someone else to tell you what to demo or when to follow up, this won&#39;t be a fit.</p>\n<p><strong>A Note On Pace</strong></p>\n<p>We operate at an absurd level of urgency because the window for what we&#39;re building won&#39;t stay open forever. If that excites you, keep reading.
