About the Team

Kardigan's Biometrics organization is the analytical backbone of our development portfolio. Working closely with Clinical Development, Medical, Regulatory Affairs, Clinical Operations, and Data Management, the team shapes how our studies are designed, how evidence is generated, and how results are interpreted and communicated to health authorities. Biostatistics is a scientific partner in program strategy, not a downstream delivery function.

We are building a team that pairs methodological depth with practical judgment and a strong sense of ownership. Team members have the opportunity to influence trial design and development decisions early, apply innovative analytical approaches in a regulatory context, and help establish the standards and ways of working that will carry Kardigan through multiple registration-directed programs. Our work helps Kardigan move with urgency while safeguarding scientific and analytical integrity, ultimately supporting our mission to bring potentially transformative treatments to people living with cardiovascular disease.

Job Overview

Kardigan is seeking a Senior Director, Biostatistics to serve as the lead statistician for one or more of our late- stage cardiovascular development programs. Reporting to the Executive Director, Head of Biostatistics, this individual owns the statistical strategy and analytical deliverables for their assigned programs, from study design through analysis, reporting, and submission support.

This is a hands-on scientific leadership role. The Senior Director is expected to bring methodological rigor and sound judgment to program design questions, to represent Biostatistics credibly on cross-functional program teams, and to serve as a statistical contributor in health authority interactions in partnership with the Head of Biostatistics. The role carries people leadership responsibility for the statisticians supporting assigned programs, along with oversight of the CRO and vendor statistical work those programs depend on.

The ideal candidate has meaningful late-phase experience - study design through analysis and submission deliverables - and is comfortable operating with a high degree of independence in a small, fast-moving company while escalating and aligning on significant methodological and regulatory positions with the Head of Biostatistics.

Main Responsibilities

• Serve as the lead statistician for one or more late-stage cardiovascular development programs, owning the statistical strategy and analytical deliverables for those programs under the direction of the Head of Biostatistics.
• Contribute to clinical development strategy by informing study design, endpoint selection, estimand frameworks, sample size and power considerations, and evidence-generation plans from protocol concept through submission.
• Author, review, and own core statistical documents for assigned programs, including statistical sections of protocols, statistical analysis plans, randomization specifications, and the statistical content of clinical study reports.
• Prepare statistical content supporting interactions with the FDA and other health authorities - including briefing package sections, meeting preparation materials, and responses to agency queries - and participate in those interactions alongside the Head of Biostatistics.
• Apply late-phase statistical methodology relevant to Kardigan's programs, including responder and subgroup analyses, adaptive design elements, Bayesian approaches, multiplicity control, and missing data strategies, and recommend approaches that are both scientifically sound and regulatorily credible.
• Serve as the statistical partner to Clinical Development, Medical, Regulatory Affairs, Clinical Operations, and Data Management, providing data-driven input on trial feasibility, statistical risk, and program-level decisions.
• Manage, mentor, and develop the biostatisticians supporting assigned programs, providing technical review, coaching, and career development.
• Oversee statistical work performed by CROs and external partners for assigned programs, maintaining scientific ownership and accountability for the quality, timeliness, and integrity of all deliverables.
• Support data monitoring committee activities, interim analyses, and unblinding procedures for assigned programs in accordance with applicable SOPs and regulatory guidelines.
• Contribute to the development and adoption of statistical standards, governance, quality systems, and submission-ready processes established across the Biostatistics function, and support inspection readiness.
• Provide statistical input to evidence-generation, publication, and business development or due diligence activities as needed.
