We are seeking a highly motivated Director of Analytical Development to lead and execute analytical strategies supporting our development pipeline. Reporting to the VP of CMC, this individual will play a critical role in advancing programs from the earliest stages of development into the clinic. The ideal candidate combines strong hands-on laboratory expertise with the ability to effectively develop junior analysts and manage external partners, in a fast-paced environment.


Key Responsibilities


Analytical Strategy & Execution


  • Drive analytical strategy to support drug substance and drug product development across multiple programs, with phase-appropriate rigor.
  • Accountable for all aspects of method design, method development, method qualification/validation, impurity identification and qualification, degradation pathway identification, shelf-life strategy, specification setting, and the overall control strategy.
  • Oversee and perform hands-on analytical work at Osanni’s development lab, including troubleshooting and method optimization.
  • Lead and manage CDMO analytical activities, including but not limited to method development, release testing, stability program design and testing, reference standard management, product characterization, and investigations (e.g., OOT/OOS, etc.).
  • Authoring and ownership of Module 3 analytical sections, as well as the ability to provide technical input across all CMC-related sections.


Leadership & Development


  • Manage and mentor at least one direct report, fostering growth and development. Scale analytical capabilities, footprint, and/or the organization as may be needed over time.
  • Operate as a deeply cross-functional leader across the development organization, driving alignment, resolving tradeoffs, and providing clear technical direction across programs.


Required Skills and Background:

  • MS in Analytical Chemistry or related field required, PhD strongly preferred, with 10 years of industry experience in small molecule analytical development
  • Demonstrated ability to work in a fast-paced startup or small biotech environment. Multi-modality experience is strongly preferred.

  • Proven experience managing CMOs/CROs and driving outsourced analytical activities.
  • Experience supporting IND-enabling activities and regulatory submissions.


What Sets the Right Candidate Apart

  • A highly autonomous leader with a builder mindset who sets standards in ambiguous environments and leads with judgment rather than relying on existing playbooks.
  • The ability to build and sustain strong, trust-based relationships with their employees, internal teams, and external partners.


The anticipated base pay range for this role is $210,000- $240,000 plus bonus and comprehensive benefits. Total compensation, including base salary to be offered, is determined by job-related skills, experience, and relevant education or training.
