As we expand Claude&#39;s capabilities, the reliability, security, and developer experience of this infrastructure becomes increasingly critical. We&#39;re looking for an engineer to join the sandboxing team and help shape both the client-side library/API and the underlying infrastructure.</p>\n<p>In this role, you&#39;ll combine deep infrastructure expertise with an obsession for developer experience. You&#39;ll help maintain and evolve a system that must be correct, performant, and intuitive to use. You&#39;ll work closely with internal teams to understand their needs, burn down errors and edge cases, and build a roadmap that anticipates where the product needs to go.

However, some roles may require more time in our offices.</p>\n<p><strong>Visa sponsorship:</strong> We do sponsor visas! However, we aren&#39;t able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.</p>\n<p><strong>We encourage you to apply even if you do not believe you meet every single qualification.</strong> Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you&#39;re interested in this work. We think AI systems like the ones we&#39;re building can have a huge impact on society, and we want to make sure that the people building them are representative of the people they&#39;ll be serving.</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_4396bfcf-940","directApply":true,"hiringOrganization":{"@type":"Organization","name":"Anthropic","sameAs":"https://job-boards.greenhouse.io","logo":"https://logos.yubhub.co/anthropic.com.png"},"x-apply-url":"https://job-boards.greenhouse.io/anthropic/jobs/5083039008","x-work-arrangement":"hybrid","x-experience-level":"senior","x-job-type":"full-time","x-salary-range":"$300,000 - $405,000USD","x-skills-required":["software engineering","API design","error propagation","documentation","complex distributed systems","reliability","observability","testing","security","sandboxing","isolation technologies","containers","VMs","seccomp","namespaces","Python ecosystem","developer tools","CLIs","platforms","incident response","on-call rotations","reinforcement learning","model training infrastructure"],"x-skills-preferred":["founder","early engineer","infrastructure-focused startup","open-source contributions","developer platform","product-market fit","user feedback","incident response","on-call rotations","reinforcement learning","model training infrastructure"],"datePosted":"2026-03-08T14:03:30.986Z","jobLocation":{"@type":"Place","address":{"@type":"PostalAddress","addressLocality":"San Francisco, CA | New York City, NY"}},"employmentType":"FULL_TIME","occupationalCategory":"Engineering","industry":"Technology","skills":"software engineering, API design, error propagation, documentation, complex distributed systems, reliability, observability, testing, security, sandboxing, isolation technologies, containers, VMs, seccomp, namespaces, Python ecosystem, developer tools, CLIs, platforms, incident response, on-call rotations, reinforcement learning, model training infrastructure, founder, early engineer, infrastructure-focused startup, open-source contributions, developer platform, product-market fit, user feedback, incident response, on-call rotations, reinforcement learning, model training infrastructure","baseSalary":{"@type":"MonetaryAmount","currency":"USD","value":{"@type":"QuantitativeValue","minValue":300000,"maxValue":405000,"unitText":"YEAR"}}},{"@context":"https://schema.org","@type":"JobPosting","identifier":{"@type":"PropertyValue","name":"YubHub","value":"job_41528416-21c"},"title":"Staff+ Software Security Engineer","description":"<p><strong>About Anthropic</strong></p>\n<p>Anthropic&#39;s mission is to create reliable, interpretable, and steerable AI systems.
