Tax Principal, Business Advisory

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.

We're seeking an experienced Tax Principal to serve as a trusted business advisor and deep technical resource across our tax function. In this role, you'll partner directly with business, product, and go-to-market teams to advise on the tax implications of strategic initiatives, new products, commercial arrangements, and market expansion — translating sophisticated technical analysis into clear, decision-ready guidance that helps the business move quickly and confidently. You'll also assist with audit defense and dispute management efforts and conduct technical research and documentation for complex tax issues across the tax team.

You'll navigate the evolving digital economy tax landscape, including digital services taxes (DSTs), Pillar 2, and emerging AI-specific tax regulations, while ensuring compliance across multiple jurisdictions. You'll be a go-to expert who can tackle sophisticated tax questions, prepare audit-quality memoranda, and translate technical concepts for business stakeholders. This role is critical to ensuring we have bulletproof tax positions, robust risk management processes, and comprehensive documentation as we face heightened scrutiny from auditors, tax authorities, and stakeholders in the rapidly evolving AI industry.

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.

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.

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.
