US Patent Attorney, Sr. Patent Counsel, Program Strategy

This role will drive IP strategy and value creation for innovations that can improve the lives of patients with severe autoimmune diseases, while helping shape how a modern intellectual property (IP) team works. We are seeking an experienced US patent attorney who combines strong legal judgment, scientific curiosity and commercial insight with a genuine appetite to challenge established ways of working.

You will build and execute global patent strategies, advise colleagues across research, development, clinical, regulatory, manufacturing, commercial and business development, and support transactions and disputes. You will also help shape an evolving agentic IP team: a team in which attorneys and IP professionals work alongside artificial intelligence (AI) agents that carry out defined, multi-step workflows under appropriate human direction and review.

Help Build an Agentic IP Team

This is a role for someone who wants to help build the next way of working, not simply use the tools already available. You will bring curiosity, practical experimentation and the judgment to distinguish where artificial intelligence agents add value from where attorney-led work remains essential.

Start with bounded use cases and improve them through feedback.Maintain Accountable Legal Oversight: Define tasks, authoritative inputs, review checkpoints and escalation rules. Verify outputs and references, protect confidential and privileged information, respect data-use restrictions, and retain attorney accountability for legal advice and consequential decisions.Build Team Capability: Partner with IP operations, technology and other colleagues to turn useful pilots into repeatable practices. Share learning, coach colleagues and assess improvements in quality, responsiveness and capacity, not simply tool usage.
