Job description

The Opportunity
We are seeking a creative and highly motivated Principal Scientist, Medicinal Chemist to join our R&D team. This is a primarily lab-based, technical leadership position within the Peptide Therapeutics department. In this lab-based leadership role, you will combine hands-on synthetic expertise with strategic oversight, driving the discovery and optimization of peptide therapeutics across the full development lifecycle.
Key Responsibilities
1. Synthetic Execution & Lab Leadership
  • Primary Bench Driver: Execute the multi-step synthesis of peptides, peptidomimetics, and novel, non-commercial building blocks or scaffolds.
  • Synthetic Mastery: Utilize expert-level skills in solid-phase peptide synthesis, solution-phase organic chemistry, and specialized macrocyclization or ligation strategies.
  • Analytical Rigor: Personally oversee high-resolution analysis (HPLC, Mass Spec, NMR) to confirm compound identity and ensure the delivery of high-purity materials.

2. Strategic Design & Technology Innovation
  • Apply conformational analysis, structure-based design, and computational modeling (e.g., MD simulations) to optimize potency, stability, and pharmacokinetics. Drive polycyclization strategies to improve drug-like properties.
  • Lead Optimization: Implement strategic SAR plans and Multi-Parameter Optimization to advance candidates from early hits through to IND-enabling studies.

3. Collaborative Leadership
  • Lead multidisciplinary project teams, serving as the technical bridge between Peptide Therapeutics, Research Biology, Drug Discovery, and Therapeutic Areas.
  • Supervise and mentor junior scientists directly at the bench, fostering a culture of technical excellence and scientific innovation.

Who You Are
  • Education: Ph.D. in Organic or Medicinal Chemistry (or related field) with 3+ years of relevant postdoctoral or industry experience.
  • Synthetic Expert: Proven mastery of both SPPS (manual and automated) and complex solution-phase organic synthesis.
  • Design Savvy: Deep knowledge of macrocyclic peptides, various routes of administration (IV, SC, PO), and library-based screening (e.g., mRNA display, AS/MS, OBOC).
  • Computationally Proficient: Experienced in using software (Schrödinger, MOE, Maestro) for molecular dynamics, conformational sampling, and AI/ML-driven sequence optimization.
  • Effective Communicator: Ability to present complex technical data and strategic roadmaps to global cross-functional stakeholders.

Relocation benefits are available for this posting.
The expected salary range for this position based on the primary location of California is $143,200 to $265,900. Actual pay will be determined based on experience, qualifications, geographic location, and other job-related factors permitted by law. A discretionary annual bonus may be available based on individual and Company performance. This position also qualifies for the benefits detailed at the link provided below.
