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 We are looking for backend / platform software engineers to join our Product Foundations org. We build foundational primitives that help accelerate product development across Anthropic. Some examples of what we own and maintain are our core sampling pipeline, our rate limiting platform, and our RAG platform.
We have multiple teams that are currently hiring. Team placement occurs after the interview process, taking into account your interests and experience alongside organizational needs. This flexible approach allows us to match talented engineers with the platform efforts where they'll have the greatest impact and growth potential:
Billing Platform We build and operate the billing infrastructure that powers all of Anthropic's products — enabling revenue collection across different pricing models, subscriptions, and multi‑entity operations for global compliance. You'll work on distributed systems that need to be both fast and correct: real‑time tracking, revenue reconciliation across payment providers, and ledger systems that ensure accuracy at scale. This is production‑critical infrastructure where data consistency matters, and you'll collaborate closely with finance, product, and accounting teams to build the foundation that scales our business. If you've built billing platforms or payment systems, that will be a big plus.
Product Platform We provide a set of stable, powerful, and easy to use shared product capabilities leveraged by the Claude.ai, API, and other internal product and research teams. You’ll work on our core platform components like rate limiting, LLM sampling and multimodal processing. Our mandate includes developing reusable components, improving system performance, and creating scalable abstractions that accelerate product development across the organization while maintaining high standards for reliability and security.
Accounts Platform We build and maintain the critical infrastructure that powers identity and authentication across Anthropic's product suite. We work closely with product teams, security, support, and trust & safety as customers. We create scalable solutions for user authentication, authorization, role‑based access control, and single sign‑on that form the backbone of our company's identity management operations. We maintain a user‑centric approach, building reliable systems that our users and company can depend on as we tackle complex challenges at the intersection of security, scalability, and user experience.
Responsibilities
Build and scale platform components to handle Anthropic’s rapid growth
Design and architect platform components that are composable and deliver value for a variety of use cases
Collaborate closely with product teams to understand their needs and build platform capabilities that accelerate their feature delivery
Make build vs buy decisions, evaluating and implementing 3rd party solutions when most impactful
Set technical direction and vision for various product and platform features
Partner with research to quickly prototype and launch new capabilities based on research breakthroughs
You might be a good fit if you:
Have 6+ years of practical experience as a backend or platform engineer building scalable distributed systems
Have strong coding skills and experience with service‑oriented architectures
Have worked in early startup or otherwise fast moving, rapidly evolving environments, and have ideally built products from 0 to 1
Take full ownership of your work, navigate ambiguity effectively, and proactively overcome obstacles to deliver results
Are comfortable diving into any part of the system, whether it's infrastructure, services, or product frontends, to deliver effective solutions
Enjoy working with a fast‑paced team tackling cutting‑edge problems in AI safety and conversational AI
Take a product‑focused approach and care about building solutions that are robust, scalable, and easy to use
Enjoy pair programming (we love to pair!)
Have a Bachelor’s degree in Computer Science, Software Engineering or comparable experience
Strong candidates may also:
Have worked with NLP and ML models and understand their capabilities and limitations
Have experience with REST APIs
Have experience with React and Frontend frameworks
The expected base compensation for this position is below. Our total compensation package for full‑time employees includes equity, benefits, and may include incentive compensation.
$320,000 - $405,000 USD
Logistics Education requirements: We require at least a Bachelor's degree in a related field or equivalent experience.
Location‑based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.
Visa sponsorship: We sponsor visas! However, we aren’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.
We encourage you to apply even if you do not believe you meet every single qualification.
Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.
As set forth in Anthropic’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.
