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 experienced software engineers to join our Platform organization. We build the foundational primitives that accelerate product development across Anthropic, and own infrastructure and systems that teams depend on to ship reliably and at scale - either internally or by hundreds of thousands of external global users and companies at all stages. You'll independently scope complex, multi-month projects, drive cross-org alignment through ambiguous problem spaces, and make architectural decisions that shape how Anthropic builds and scales its products. You'll partner directly with research to productize cutting-edge capabilities, and will have lasting impact on the platform that hundreds of thousands of companies and internal/external engineers depend on every day.
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 backend product efforts where they'll have the greatest impact and growth potential.
Platform Acceleration: We work on maximizing the developer productivity of product engineers at Anthropic. You'll architect and optimize the critical development infrastructure that powers our AI product development, including dev environments, observability, and CI/CD pipelines. You’ll partner closely with product teams to understand their development workflow and eliminate friction points. Your work will have an extraordinary multiplier effect, enhancing productivity across our entire product organization and accelerating our mission.
Service Infra: we build and maintain the core infrastructure that powers Anthropic's engineering organization, from service mesh and observability systems to deployment pipelines and shared libraries. Our work enables product teams to build and operate reliable services at scale, making us a critical force multiplier across the entire company.
Multicloud: We build and maintain the infrastructure that enables Anthropic to operate across multiple cloud providers. We focus on cloud-agnostic tooling, cross-cloud networking, and multi-region deployments.
Auth & Identity: 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.
Connectivity: Our mission is to make Claude the most connected AI. We own the MCP proxy that routes every tool call and the OAuth and token management that keeps connections authenticated. We're also the core contributors to the MCP spec — now an open standard under the Linux Foundation — and maintain the official Python and TypeScript SDKs. You'll work on problems where reliability and enterprise trust are the bar: token refresh at scale, admin controls that let IT govern what agents can do, proxy infrastructure that stays up when partner servers don't. We ship for claude.ai, Claude Code, Cowork, and the API. Relevant experience includes OAuth, API gateways, multi-tenant platforms, building for enterprise, and MCP.
API Distributability: The Claude API today is a rapidly growing platform serving developers and enterprises at scale—but reaching the next tier of enterprise customers requires transforming how and where we deploy it. The Distributability team owns that transformation: making the Claude API a cloud-native, managed product that runs wherever our customers need it, cross-cloud and on Anthropic's own infrastructure, with the enterprise-grade security, compliance, and operational capabilities to support it.
Platform Intelligence: We build the training systems that adapt Claude to specific customer workloads. The core problem is task-specific adaptation: getting the right intelligence, cost, and latency profile for a particular use case, and building toward systems where that adaptation can deepen as the customer's usage grows. We work closely with research on training methods and with agent platform teams on data paths. Relevant experience: ML training infra, production ML pipelines, backend engineering. Finetuning experience is a plus.
You Might Be a Good Fit If You
- Have 8-10+ years of practical full-stack engineering experience, ideally with 2+ years operating at a Staff or equivalent technical leadership level
- Have led the design and delivery of complex, consumer or B2B user-facing products across the full stack
- Are a technical expert in modern frontend and backend development, with demonstrated depth in key languages and frameworks (ie. React, Typescript)
- Take a product-focused approach to building solutions that are robust, scalable, and easy to use
- Have worked in early start-up or otherwise fast moving, rapidly evolving environments, and have ideally built products from 0 to 1
- Care deeply in investing in the mentorship and growth of your peers
- Have successfully driven cross-team/cross-org organizational alignment to get impactful work shipped, and work with influence over authority
- Have experience establishing engineering standards, component architectures, and development best practices
- Thrive in fast-paced environments and can navigate ambiguity to deliver high-quality products
Strong Candidates May Also
- Served as a technical lead or architect for a foundational platform system, owning both the technical vision and execution end-to-end
- Experience designing or scaling billing, payments, or financial infrastructure at high transaction volumes
- Deep familiarity with containerization, secure execution environments, or infrastructure where security and capability need to coexist
- Built identity and access management systems (authentication, authorization, SSO, RBAC) at enterprise scale
- Experience with ML/AI systems, LLM inference, model serving pipelines, or the infrastructure that supports them
- Experience with multi-cloud deployments, cross-region architectures, or cloud-agnostic tooling
- Experience designing and reviewing APIs with a focus on developer experience, consistency, and reliability
Deadline to apply: None. Applications will be reviewed on a rolling basis.
Location Preference: Preference will be given to candidates based in NY, NJ, SEA, SF or the Bay Area given the current location of team.
The annual compensation range for this role is listed below. For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role.
Annual Salary
$405,000—$485,000 USD
Logistics
Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience
Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience
Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position
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 do 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. 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're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.
Your safety matters to us.

How We're Different
We believe that the highest-impact AI research will be big science. 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 to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
Come work with us!
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.

Get Access To All JobsTips for Finding Staff Software Developer Jobs at Anthropic Jobs
Frame your systems experience around safety-critical work
Anthropic evaluates Staff engineers on their ability to build reliable infrastructure for high-stakes AI systems. When preparing your resume and portfolio, emphasize prior work on distributed systems, model serving, or reliability engineering where failure had real consequences.
Target roles that align with your visa classification
Anthropic sponsors H-1B, H-1B1, and E-3 visas for this role. If you hold Australian citizenship, the E-3 path avoids the H-1B lottery entirely. Confirm your eligibility before applying so your recruiter conversation starts with sponsorship already scoped.
Prepare for a specialty occupation documentation request
USCIS requires that H-1B petitions demonstrate the role qualifies as a specialty occupation. For Staff Software Developer positions at Anthropic, gather degree transcripts and any publications or technical writing that connect your academic background directly to AI infrastructure or research engineering.
Ask about LCA timing before accepting an offer
Your employer must file a Labor Condition Application with DOL before USCIS can process your H-1B petition. Ask Anthropic's recruiting team which immigration counsel they use and what the typical turnaround is from offer acceptance to LCA certification, so you can plan your start date accurately.
Use Migrate Mate to find open Staff Software Developer roles at Anthropic
Anthropic's sponsorship-eligible engineering positions aren't always flagged on general job boards. Use Migrate Mate to filter for Staff Software Developer openings at Anthropic by visa type, so you're applying to roles where sponsorship is already confirmed for your classification.
Treat the technical interview as a research collaboration signal
Anthropic's Staff-level interviews often test how you reason through novel technical constraints, not just how well you execute known patterns. Review publicly available writing from Anthropic's engineering and research teams to calibrate the level of rigor and first-principles thinking they expect.

Find Staff Software Developer at Anthropic JobsFrequently Asked Questions
Does Anthropic sponsor H-1B visas for Staff Software Developers?
Yes, Anthropic sponsors H-1B visas for Staff Software Developer roles. The company also sponsors H-1B1 and E-3 visas, giving Australian and Singapore nationals additional pathways that bypass the H-1B lottery. Sponsorship is handled through Anthropic's in-house immigration process and external counsel, and the expectation of sponsorship should be confirmed with your recruiter early in the process.
Which visa types are commonly used for Staff Software Developer roles at Anthropic?
The H-1B is the most common path for Staff Software Developer roles at Anthropic, but the company also sponsors H-1B1 visas for Singapore citizens and E-3 visas for Australian citizens. Both the H-1B1 and E-3 avoid the annual H-1B lottery, which can meaningfully shorten your path to starting work. All three classifications require a qualifying specialty occupation and an employer-filed Labor Condition Application with DOL.
What qualifications and experience does Anthropic expect for Staff Software Developer roles?
Anthropic's Staff Software Developer roles typically require deep experience in distributed systems, large-scale infrastructure, or ML platform engineering. Staff-level candidates are expected to drive technical direction, not just execute on it. Relevant backgrounds include model training infrastructure, high-throughput serving systems, and reliability engineering at scale. Research experience or familiarity with AI safety considerations is a distinguishing factor at this level.
How do I apply for Staff Software Developer jobs at Anthropic?
You can browse and apply for Staff Software Developer openings at Anthropic through their careers page or through Migrate Mate, which filters roles by visa sponsorship type so you can confirm eligibility before applying. Applications typically involve a resume review, an initial recruiter screen, and a multi-stage technical interview covering systems design and engineering judgment. Flagging your visa needs early in the recruiter conversation avoids delays later.
How do I plan my timeline when switching to an Anthropic-sponsored H-1B?
If you're already in the U.S. on a valid status, a cap-exempt transfer or change of status can sometimes be filed concurrently with your I-129 petition. For cap-subject H-1B filings, USCIS typically opens registration in March for an October 1 start date, so plan backwards from that window. If you're between jobs and inside a 60-day grace period, timeline pressure is real and you should notify Anthropic's recruiting team immediately so filing can be expedited.
