Human Resources (HR) Manager

Yowei Therapeutics and Yowei Oncology are stealth-stage life-sciences companies working closely with CSBio to advance peptide-based clinical programs. Their work spans longevity and peptide therapeutics, clinical trials, evaluation of a 503A pharmacy model, personalized synthetic neoantigen peptide oncology programs, and supporting microbiology and laboratory capabilities. Together, they are building the clinical, pharmacy, data, laboratory, and operational infrastructure needed to responsibly translate peptide programs into patient-facing studies and services. Both companies expect to remain in stealth through Q1 2027.

CSBio is a peptide contract manufacturing founded in 1993. CSBio initial products were a complete line of automated synthesizers for manufacturing and process development, with a focus on cGMP production. In 1994, CSBio opened a custom peptide facility and began producing high quality compounds for research organizations and pharmaceutical companies worldwide. In 2004, CSBio opened a peptide production facility in Menlo Park, CA and in 2014, CSBio expanded production capability through the addition of a new, state of the art building dedicated to cGMP peptide production. In 2017, CSBio passed a FDA inspection and were recommended to be approved for commercial drug substance manufacturing. In 2023, additional cGMP clinical production capacity was added in Milpitas, CA.

We are seeking qualified individuals to join us as Human Resources Manager. Core duties and responsibilities include the following:

Job Duties:

• Lead the HR function across Yowei Therapeutics, Yowei Oncology, and shared CSBio teams; manage day-to-day HR operations, priorities, and any HR coordinators or outside HR service providers.

• Run full-cycle recruiting for scientific, clinical, pharmacy, quality, laboratory, and operations roles, including workforce planning, job descriptions, sourcing, interview coordination, offers, and background checks.
• Protect the companies' stealth status throughout hiring and HR operations by managing confidential postings, candidate NDAs, controlled communications, and need-to-know access to information.
• Own onboarding and offboarding, ensuring new hires complete required safety, GMP, data-integrity, and role-specific training before starting regulated work.
• Partner with Quality Assurance to maintain training records, curricula vitae, job descriptions, and qualification files that are complete, current, and inspection-ready for FDA, customer, and internal audits.
• Track professional licenses, registrations, and certifications for pharmacists, pharmacy technicians, clinical staff, and other credentialed personnel, including renewals and primary-source verification, as the 503A pharmacy model and clinical programs develop.
• Administer payroll, benefits, leave, and open enrollment across multiple legal entities in coordination with Finance, brokers, and the payroll provider; ensure accurate employee classification and entity assignment.
