Staff+ Software Engineer, Platform Intelligence

San Francisco, CA | New York City, NY

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

Platform Intelligence turns each new Claude model's abilities into API features that developers can build on. Our goal is to make the full intelligence of each model available through the API. We own the capabilities that shape what Claude can do for developers: tool use, built-in tools such as web search and code execution, thinking controls, structured outputs, and the memory, files, and skills APIs.

We also run the API side of every Claude model launch, including its safety features and controls. That means getting the API ready for each new model, coordinating with research, safeguards, product, and cloud partners, and making sure the model, its features, the SDKs, and the docs all ship together on launch day.

The work sits where research meets product. We work with new models before they are public. When a model gains a new ability, we work out what it should look like as an API, build it, and ship it to developers on our own platform and on cloud platforms. Those decisions shape how developers first use each model. We also own API versioning and the evals that tell us a capability works in production.

What you'll do

You'll lead the design, build, and operation of API capabilities used by developers around the world. You'll work with research to understand what a new model can do and turn that into an interface that is simple, durable, and hard to misuse.

You'll lead the API side of new model launches. You'll plan the work, track readiness across teams, resolve the issues that come up late, and see the launch through on the day. Between launches, you'll make the next one faster and safer.

You'll set technical direction for work that spans several teams, write clear design proposals, review API designs from other teams, and mentor engineers on the team.

Representative projects

  • Lead API readiness for a Claude model launch, so that every feature works on day one across our API, SDKs, docs, and cloud partners
  • Take a new model ability from research prototype to public API feature, from interface design to production rollout
  • Build and operate tools such as web search and code execution under real traffic
  • Automate the manual parts of a model launch
  • Build the evals that catch a capability regression before a launch

You might be a good fit if you:

  • Have led technical projects that spanned several teams, from design through launch and operation
  • Have designed and operated production distributed systems where correctness, latency, and availability all matter
  • Have strong product sense and care about API design and developer experience
  • Make sound technical decisions with incomplete information, as models and priorities change close to a launch
  • Explain tradeoffs clearly to research, product, and go-to-market partners, including non-engineers
  • Make the engineers around you better through design review and mentoring
  • Use AI tools as a regular part of how you design, build, and review software
  • Care about the societal impacts of your work and Anthropic's mission to build safe, beneficial AI

Strong candidates may also have:

  • Building public APIs, SDKs, or developer platforms
  • Working with large language models, including tool use, agents, or evals
  • Running launches or migrations with fixed deadlines and many dependent teams
  • Building tools for agents, such as search or code execution
  • Storage, memory, or context systems at scale
  • Integrating with cloud platforms such as AWS, Google Cloud, and Azure

Deadline to apply: None. Applications will be reviewed on a rolling basis. 

Location Preference: Preference will be given to candidates based in NY, 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. To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses. In some cases, we may partner with vetted recruiting agencies who will identify themselves as working on behalf of Anthropic. Be cautious of emails from other domains. Legitimate Anthropic recruiters will never ask for money, fees, or banking information before your first day. If you're ever unsure about a communication, don't click any links—visit anthropic.com/careers directly for confirmed position openings.

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.

Agreement to Arbitrate

I understand and agree that both Anthropic and I waive our respective rights to trial by jury in connection with any claims covered by this agreement to arbitrate. Instead, any disputes arising out of or related to my application for employment with Anthropic shall be settled by final and binding arbitration pursuant to the Federal Arbitration Act. I understand and agree that Anthropic’s employees/agents, Anthropic’s clients, and their employees/agents are third-party beneficiaries to this agreement.

The arbitration shall be conducted in accordance with the Employment Arbitration Rules & Procedures of Judicial Arbitration and Mediation Services, Inc. (“JAMS Rules”), available via the internet at https://www.jamsadr.com/rules-employment-arbitration or by searching for “JAMS Employment Arbitration Rules” in an online search service such as www.google.com. To the extent the JAMS Rules are inconsistent with the terms of this Agreement, this Agreement shall govern to the extent permitted by law. The parties will select one neutral arbitrator, who will have the authority to award all relief in law or equity that is requested by the parties and supported by credible, relevant, and admissible evidence. The arbitrator shall allow adequate discovery and issue a written, signed, and reasoned award. Judgement may be entered on the arbitrator’s award in any court having jurisdiction, and the award shall be subject to correction, confirmation, or vacation as provided by the applicable law concerning judicial review of arbitration awards. Anthropic will bear the costs that are particular to the arbitration, such as the arbitrator fees. The arbitrator will apply the substantive law of the state in which I sought employment with Anthropic. The arbitrator will determine the arbitration venue, based on fairness and convenience to the parties and witnesses, unless otherwise mutually agreed upon by the parties. The Party initiating a claim under this Agreement must make a written demand for arbitration to the other Party. The demand for arbitration shall identify the claims asserted, the facts upon which such claims are based, and any relief or remedy sought. Written demand for arbitration to Anthropic must be sent to Anthropic PBC at arbdemands@anthropic.com. Anthropic’s demand for arbitration shall be sent to the most recent mailing address and/or email address that Anthropic has on file for you. 

This agreement to arbitrate does not apply to claims for workers’ compensation, unemployment compensation benefits, claims or charges before any administrative agency having jurisdiction over such claims, or any other claim that is not subject to arbitration under federal law. If any claims are deemed non-arbitrable, then those claims will be stayed until resolution of any arbitrable claims.

I understand and agree that, except where prohibited by federal law, all claims subject to this agreement to arbitrate must be pursued on an individual basis, and that both I and Anthropic waive any right to bring or be a party to any class or collective action. I agree that any issues pertaining to the enforceability, application or validity of this agreement to arbitrate shall be decided only by a court of competent jurisdiction and not by an arbitrator. This agreement to arbitrate applies only in the United States.
