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 ML Engineers and Research Engineers to help detect and mitigate misuse of our AI systems. As a member of the Safeguards ML team, you will build systems that identify harmful use—from individual policy violations to sophisticated, coordinated attacks—and develop defenses that keep our products safe as capabilities advance. You will also work on systems that protect user wellbeing and ensure our models behave appropriately across a wide range of contexts. This work feeds directly into Anthropic's Responsible Scaling Policy commitments.
Responsibilities
- Develop classifiers to detect misuse and anomalous behavior at scale. This includes developing synthetic data pipelines for training classifiers and methods to automatically source representative evaluations to iterate on
- Build systems to monitor for harms that span multiple exchanges, such as coordinated cyber attacks and influence operations, and develop new methods for aggregating and analyzing signals across contexts
- Evaluate and improve the safety of agentic products—developing both threat models and environments to test for agentic risks, and developing and deploying mitigations for prompt injection attacks
- Conduct research on automated red-teaming, adversarial robustness, and other research that helps test for or find misuse
You may be a good fit if you
- Have 4+ years of experience in ML engineering, research engineering, or applied research, in academia or industry
- Have proficiency in Python and experience building ML systems
- Are comfortable working across the research-to-deployment pipeline, from exploratory experiments to production systems
- Are worried about misuse risks of AI systems, and want to work to mitigate them
- Have strong communication skills and ability to explain complex technical concepts to non-technical stakeholders
Strong Candidates May Also Have Experience With
- Language modeling and transformers
- Building classifiers, anomaly detection systems, or behavioral ML
- Adversarial machine learning or red-teaming
- Interpretability or probes
- Reinforcement learning
- High-performance, large-scale ML systems
Annual Salary
$350,000—$500,000 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 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.

Align your credentials with safety research
Anthropic's ML roles sit at the intersection of engineering and research. Framing your experience around model training, alignment techniques, or interpretability work strengthens your application well before you submit anything to USCIS.
Target roles by research area not job title
Anthropic posts ML Software Engineer roles across distinct teams: pretraining, RLHF, and inference. Applying to the team whose published research matches your background signals genuine fit, which matters when an employer is weighing visa sponsorship costs.
Track open roles using Migrate Mate
Anthropic's ML Software Engineer openings move quickly. Use Migrate Mate to filter for Anthropic roles by visa type so you're applying when positions are live, not after a requisition closes.
Clarify your visa status early in interviews
Anthropic sponsors H-1B, H-1B1 visa, and E-3 visas. Confirming which category applies to you before the offer stage prevents delays, since each visa type has different DOL Labor Condition Application requirements your employer must file before you can start.
Prepare for a research-weighted technical process
Anthropic's ML interview loop includes systems design and ML theory rounds alongside coding. Having published work, open-source contributions, or documented experiments makes the sponsorship conversation easier because the technical bar is already cleared.
Account for LCA and I-129 timing in your start date
Your employer must file a certified Labor Condition Application with DOL before USCIS can process your H-1B petition. Build at least six to eight weeks into your expected start date to account for LCA certification and petition processing after you receive an offer.
Frequently Asked Questions
Does Anthropic sponsor H-1B visas for ML Software Engineers?
Yes, Anthropic sponsors H-1B visas for ML Software Engineers. The company also sponsors H-1B1 visas for eligible nationals from Chile and Singapore, and E-3 visas for Australian citizens. Sponsorship is handled through standard USCIS petition processes, and Anthropic has an established track record of filing across these categories for technical and research roles.
Which visa types are commonly used for ML Software Engineer roles at Anthropic?
ML Software Engineers at Anthropic most commonly work on H-1B visas, which require a specialty occupation and a bachelor's degree or higher in a related field. Australian citizens can pursue the E-3, which has no annual lottery and allows two-year renewable periods. Nationals from Chile and Singapore may qualify for the H-1B1 visa. All three require a certified Labor Condition Application filed with DOL before USCIS processing begins.
What qualifications or experience does Anthropic expect for ML Software Engineer roles?
Anthropic typically looks for strong foundations in machine learning, deep learning systems, and large-scale model training. Research experience, whether through publications, graduate work, or significant open-source contributions, is weighted heavily. Proficiency in Python and experience with distributed training frameworks are standard expectations. Roles on alignment or interpretability teams often require familiarity with RLHF or mechanistic interpretability research.
How do I apply for ML Software Engineer jobs at Anthropic?
You can find and filter current ML Software Engineer openings at Anthropic by visa type on Migrate Mate, which lets you confirm sponsorship eligibility before you apply. Applications go through Anthropic's careers portal. The process typically includes a recruiter screen, a technical phone interview, and a multi-round loop covering ML systems, coding, and research discussions. Communicating your visa status early prevents delays at the offer stage.
How long does the visa sponsorship process take after receiving an offer from Anthropic?
After an offer, your employer must obtain a certified Labor Condition Application from DOL, which typically takes one to two weeks under standard processing. USCIS then processes the I-129 petition, which can take two to six months under regular processing or as little as two to three weeks with premium processing. For H-1B cap-subject cases, timing also depends on the annual lottery cycle, with petitions eligible for an October 1 start date each fiscal year.
