Global Regulatory Affairs Director — Hybrid​/Remote

The Senior Director, Global Regulatory Affairs will provide strategic regulatory leadership across Janux’s clinical-stage oncology pipeline, supporting programs from early development through registration. This individual will lead global regulatory strategy for one or more programs while influencing and partnering closely with cross-functional stakeholders to shape development plans and ensuring alignment across functions in a dynamic, fast-paced environment.

This role requires a hands-on regulatory leader with deep experience in early clinical development (Phase 1/2), coordinating multiple parallel regulatory initiatives, strong health authority interaction experience, the ability to exercise judgment with decisions that have long-term impact on regulatory function success, and guide teams through ambiguity and evolving data.

Essential Functions And Responsibilities

• Lead the development and execution of global regulatory strategies across early- and late-stage programs, ensuring alignment with overall portfolio objectives.
• Translate strategic plans into functional and operational regulatory execution across cross-functional teams including Clinical, CMC, Biometrics, and Translational Sciences.
• Serve as the regulatory lead on cross-functional program teams, driving alignment and enabling timely, high-quality decision-making.
• Influence key program decisions, including trial design, dose escalation strategies, endpoints, and development pathways based on regulatory considerations.
• Lead regulatory strategy for early clinical development (Phase 1/2), including IND/CTA planning, protocol input, and health authority engagement.
• Provide regulatory leadership for global clinical trial strategy, including EU Clinical Trial Regulation (CTR) and CTA submissions.
• Serve as the primary regulatory contact with global health authorities (e.g., FDA, EMA, Health Canada, MHRA), leading critical interactions including meeting strategy, briefing documents, negotiations, and follow-up activities.
• 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.

• 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.
• Strong leadership skills, including experience mentoring, developing, and influencing teams.
• Ability to lead through influence across functions without direct authority.
