• Evaluate and advise on regulatory pathways, including expedited programs (e.g., Fast Track, Breakthrough Therapy, Orphan Drug) and regional strategies.
• Assess emerging clinical and nonclinical data and translate insights into adaptive regulatory strategies, adjusting development plans as needed.
• Identify regulatory risks and lead mitigation strategies in the context of incomplete or evolving data.
• Operate effectively in complex environments, working with abstract concepts and cross-functional inputs to shape regulatory direction.
• Drive alignment across functions in situations with ambiguity, competing priorities, or limited precedent.
• Exercise a high degree of judgment; decisions carry long-term impact on regulatory function success and program advancement.
• Negotiate critical regulatory and strategic matters with senior and executive-level stakeholders internally and externally.
• Contribute to the development and continuous improvement of regulatory processes, systems, and best practices to support organizational growth.
• Collaborate with internal teams and external partners to ensure high-quality and timely execution of regulatory deliverables.

• BS in life sciences or related field required; advanced degree (PhD, PharmD, MD, or equivalent) preferred.
• Minimum of 12–15+ years of regulatory affairs experience in biotechnology or pharmaceutical industry.
• Experience spanning early clinical development (Phase 1/2) through later-stage development global regulatory strategy for oncology or related therapeutic areas.
• Direct experience with IND and global CTA submissions, including EU CTR.
• Proven track record of leading health authority interactions (FDA and ex-US) and influencing development strategy.
• Ability to operate effectively in environments with uncertainty, shifting priorities, and incomplete data.
• Demonstrated ability to work with complex and abstract problems across multiple functional areas.
