- Full-time
- On-site
CSBio is a peptide contract manufacturing founded in 1993. Our initial products were a complete line of automated synthesizers for manufacturing and process development, with a focus on cGMP production. In 1994, we opened our custom peptide facility and began producing high quality compounds for research organizations and pharmaceutical companies worldwide. In 2004, we opened our peptide production facility in Menlo Park, CA and in 2014, we expanded our production capability through the addition of a new, state of the art building dedicated to cGMP peptide production. In 2017, we passed a FDA inspection and were recommended to be approved for commercial drug substance manufacturing. In 2023, we added additional cGMP clinical production capacity in Milpitas, CA.
Position Summary
As Director of Quality Control, you will lead our QC laboratory operations and analytical chemistry function during a critical growth phase. You will be responsible for establishing and scaling world-class analytical testing, method validation, and release testing protocols for our cGMP peptide manufacturing facility. This is a hands-on technical and leadership role reporting to the VP of Operations, with direct authority over QC operations, analytical method development, laboratory staff, and testing strategy.
You will oversee in-process controls, final product release testing, stability studies, and analytical chemistry excellence that ensure product quality and regulatory compliance. This role bridges chemistry expertise with manufacturing operations, directly impacting batch release, CDMO customer confidence, and manufacturing efficiency.
Key Responsibilities
Site Operations
• Lead and mentor QC laboratory team of 5-8 analysts and chemists; establish performance metrics, career development, technical training programs, and ensure high-throughput testing operations
• Develop, validate, and implement analytical methods for peptide characterization including HPLC, LC-MS/MS, mass spectrometry, amino acid analysis, and peptide sequencing
• Manage in-process controls (IPC) strategy; establish sampling plans, acceptance criteria, and real-time testing to support manufacturing decisions
• Oversee final product release testing; manage batch record reviews, generate release reports, and ensure timely product disposition (release, reject, rework)
• Design and execute stability studies (ICH Q1A/Q1B); manage sample collection, analytical testing schedules, and data integrity for regulatory submissions
• Ensure analytical method validation per ICH Q2(R2); conduct validation studies, manage validation protocols, statistical analysis, and prepare validation reports
• Manage lab equipment (HPLC, LC-MS, mass spec, thermal analysis); oversee instrument qualification, preventive maintenance, and vendor relationships
• Develop and maintain analytical specifications; establish justified specification ranges based on process capability, ICH guidance, and historical data
• Lead investigation of out-of-specification results and failed batches; conduct root cause analysis and implement corrective actions
• Support process characterization and scale-up activities; develop analytical strategies for new products and manufacturing processes
• Prepare testing data packages for regulatory submissions (IND, CMC dossiers); ensure data integrity compliance (21 CFR Part 11, ALCOA+)
• Manage laboratory information management systems (LIMS) and electronic batch records; drive digitalization of QC operations
• Support CDMO customers with testing, method transfer, and analytical troubleshooting; maintain customer confidence through responsive QC support
System Optimization
· Support the design, implementation, and continuous improvement of core quality systems.
· Ensure systems are compliant, practical, efficient, and usable for front-line teams; identify opportunities to simplify workflows, reduce inefficiencies, and improve adoption.
Audit/Inspection Lead
· Lead and independently host regulatory and client audits/inspections, serving as the primary quality representative and front-room lead for assigned audits and inspections.
· Develop sufficient operational subject matter expertise across key areas beyond Quality, including Manufacturing, Facilities, Validation, and related support functions, so that within approximately 6 months the individual can confidently represent and defend these operations in front of FDA, EU, clients, and other auditors without over-reliance on others.
· Lead audit and inspection follow-up, including drafting and driving effective responses, CAPAs, commitments, and remediation plans, and ensuring actions are completed on time and are operationally practical and sustainable.
Hands-On Leadership
· Model CSBio's expectation that leaders understand operations at a task level; to observe workflows, understand bottlenecks, and identify where quality or execution is breaking down.
· Demonstrate willingness to roll up sleeves, dive into operational details, and help solve problems directly when needed; use firsthand operational knowledge to recommend practical solutions and realistic milestones.
Team Development
· Foster a culture of initiative, urgency, accountability, and continuous improvement within the QA and QC teams; ensure issues are surfaced early, discussed openly, and resolved with practical, sustainable solutions.
· Provide coaching and support to team members and emerging leaders to strengthen operational understanding, problem solving, and execution.
Growth Path
This role is intended for someone who can operate as a strong quality operations leader now and grow into broader Director of Quality responsibilities over time. Progression will depend on demonstrated ability to lead QA and QC operations with increasing independence, translate operational knowledge into practical quality goals and milestones, shape and improve systems that fit CSBio's business model, support and eventually lead audits and inspections with confidence, and develop team capability across functions.
