 Headquartered in Boston, Massachusetts, Centessa was recognized as a Great Place to Work® in 2026.

Description of Role

Centessa is currently seeking a Senior Advisor, Regulatory Starting Material. The individual in this Associate Director level role will lead the strategy, justification, and regulatory positioning of Regulatory Starting Materials for drug substance manufacturing processes supporting late-stage clinical and commercial programs. Reporting to the Vice President, CMC, this role will serve as the internal and external subject matter expert on RSM selection in accordance with ICH Q11 and applicable regional guidance, ensuring synthetic routes, GMP starting points, and supply strategies are scientifically sound, regulatorily defensible, and aligned with commercial manufacturing readiness. This individual will partner closely with Process Chemistry, Analytical Development, Regulatory Affairs, Quality, and external manufacturing partners to build and defend RSM strategy through health authority interactions and regulatory submissions.

What you need

  • Advanced degree in chemistry, chemical engineering, or a related field; PhD strongly preferred.
  • 8-10 years of relevant experience in CMC, process chemistry or drug substance/API development and manufacturing, including demonstrated leadership of starting material or CMC regulatory strategy programs.
  • Demonstrated experience supporting late-stage clinical and/or commercial drug substance programs.
  • Deep working knowledge of ICH Q11 and applicable regional guidance/expectations governing the selection and justification of Regulatory Starting Materials.
  • Demonstrated experience authoring and defending CMC regulatory submission content, including direct experience in health authority interactions related to starting material or drug substance manufacturing strategy.
  • Strong background in synthetic/process chemistry, with the ability to critically evaluate route scouting, impurity control strategy, and structural relevance arguments for candidate starting materials.
  • Experience managing relationships with drug substance/API CMOs and raw material suppliers, including batch record reviews and overarching manufacturing oversight.
  • Working knowledge of cGMP requirements as they apply to drug substance manufacturing and the GMP/non-GMP boundary.
  • Experience supporting technology transfer of drug substance processes from clinical to commercial scale preferred.
  • Strong leadership, cross-functional collaboration, and scientific writing/communication skills; exercises judgment within broadly defined practices and policies in determining solutions and actions.
  • Demonstrated ability to identify and address starting material-related risks that could jeopardize regulatory timelines, supply, or overall program success.

What you'll do

  1. Lead the identification, justification, and regulatory strategy for Regulatory Starting Materials across drug substance synthetic routes, in accordance with ICH Q11 and relevant regional guidance/reflection papers.
  2. Actively manage the starting material resupply campaigns and scale-up efforts, including on-going inventory, production forecast, manufacturing timing, production suite slot reservations, and contracting.
  3. Author and review CMC regulatory submission content related to RSM selection and justification (e.g., Module 3 sections, briefing documents, agency responses) in support of INDs/NDAs /MAAs.
  4. Prepare and lead health authority interactions (e.g., Type C meetings, scientific advice procedures) related to starting material strategy; develop briefing packages and represent the company in agency discussions.
  5. Partner with Process Chemistry and Analytical Development to evaluate synthetic routes, assess structural relevance of candidate starting materials, and support impurity fate-and-purge and risk assessments that inform RSM designation.
  6. Define and document the boundary between non-GMP and GMP manufacturing steps for drug substance processes, ensuring alignment with CMOs and internal quality standards.
  7. Lead technology transfer and process changes affecting RSM designation as programs advance from late-stage clinical development toward commercial manufacturing.
  8. Manage relationships with drug substance/API CMOs and RSM suppliers, including technical oversight, site visits, and support for supplier qualification and dual-sourcing strategies.
  9. Monitor evolving global regulatory guidance and agency precedent on starting material selection; translate changes into updated internal strategy, templates, and risk assessments.
  10. Collaborate cross-functionally with Regulatory Affairs, Quality, Supply Chain, and Manufacturing to ensure RSM strategy supports program timelines, submission readiness, and commercial supply continuity.
  11. Support due diligence activities (e.g., licensing, partnering) requiring assessment of drug substance manufacturing routes and starting material risk.
  12. Provide subject matter expertise during regulatory inspections and audits related to drug substance manufacturing and starting material justification.
  13. Build, lead, and mentor a team supporting RSM and drug substance CMC strategy activities (scope dependent on level).
  14. Domestic and international travel required (approximately 10–20%).
