Requirements
  • Bachelor’s degree in Chemical Engineering, Biochemical Engineering, Bioprocess Engineering, or closely related life sciences field required.
  • Minimum 6–8+ years of progressive experience in bioprocess development, MSAT, or GMP manufacturing within the biopharmaceutical or cell and gene therapy industry, commensurate with degree level.
  • Demonstrated expertise in advanced technology transfer, including hands-on leadership of complex tech transfer programs from process development through GMP manufacturing; CDMO or CMO experience highly preferred.
  • Experience in cell therapy (CAR-T, TIL, NK, or similar), gene therapy (AAV, lentiviral, or other viral vectors), or adjacent CGT modalities is highly preferred.
  • Experience supporting IND, IMPD, or BLA filings with the ability to author and critically review CMC sections of regulatory submissions, working knowledge of ICH Q8, Q9, Q10, Q11, and Q12 guidelines.
  • Deep understanding of GMP regulations (21 CFR Parts 210/211/600/610, EU GMP Annex 1/15) as applied to advanced therapy manufacturing; strong command of GMP documentation practices including SOP authorship, batch record design, deviation management, and CAPA.
  • Working knowledge of process characterization, design of experiments (DoE), and data-driven process optimization methodologies; familiarity with analytical methods used to characterize cell and gene therapy products (i dentity, potency, purity, safety testing).
  • Demonstrated ability to operate with a high degree of independence, define scope, manage competing priorities, and deliver results in a fast-paced, dynamic environment.
  • Strong technical writing capability with experience authoring SOPs, batch records, validation protocols, deviation reports, and regulatory submission content; excellent cross-functional communication and collaboration skills.
Responsibilities
  • Lead the GMP implementation of internal platform processes for cell and gene therapy modalities, including upstream and downstream unit operations.
  • Collaborate closely with Process Development to evaluate platform candidates, align on scalable manufacturing approaches, and ensure all platforms are structured to support CMC regulatory expectations for regulatory filings.
  • Serve as a technical lead for technology transfer, validation, and lifecycle management initiatives.
  • Contribute to CMC regulatory submissions by authoring and reviewing CMC module 3 sections, development summaries, and supporting data packages for applicable regulatory filings.
  • Apply deep CMC knowledge to ensure internal platform processes align with current regulatory guidance (FDA, EMA, ICH Q8/Q9/Q10/Q11/Q12) and support the development of CMC content strategies.
  • Serve as an MSAT lead for advanced technology transfer activities, including transfers from external clients and inbound transfers from internal process development groups.
  • Develop and execute comprehensive tech transfer plans including process descriptions, batch records, comparability strategies, and acceptance criteria.
  • Lead the identification, evaluation, procurement, and implementation of GMP manufacturing equipment required to enable platform capabilities and enhance existing capabilities.
  • Author, review, and approve SOPs, work instructions, master batch records, and other GMP-controlled documents for processes and associated equipment.
  • Provide technical oversight during engineering and GMP manufacturing runs to evaluate process reproducibility, identify performance gaps, and drive data-driven continuous improvement initiatives.
  • Function as the MSAT subject matter expert (SME) across cross-functional teams spanning Process Development, Quality, Regulatory and Manufacturing.
  • Provide technical mentorship and guidance to junior MSAT engineers and manufacturing specialists; develop and deliver training materials for platform processes, equipment, necessary systems.
  • Own, drive, and support quality management records, including but not limited to deviations, CAPAs, change controls, SCARs and effectiveness checks.
Desired Qualifications
  • Advanced degree (Master of Science or Doctor of Philosophy) in Chemical Engineering, Biochemical Engineering, Bioprocess Engineering, or closely related life sciences field is strongly preferred.
  • 6–8+ years of progressive experience in bioprocess development, MSAT, or GMP manufacturing within the biopharmaceutical or cell and gene therapy industry, commensurate with degree level.
  • Demonstrated expertise in advanced technology transfer, including hands-on leadership of complex tech transfer programs from process development through GMP manufacturing; CDMO or CMO experience highly preferred.
  • Experience in cell therapy (CAR-T, TIL, NK, or similar), gene therapy (AAV, lentiviral, or other viral vectors), or adjacent CGT modalities highly preferred.

  • Deep understanding of GMP regulations (21 CFR Parts 210/211/600/610, EU GMP Annex 1/15) as applied to advanced therapy manufacturing; strong command of GMP documentation practices including SOP authorship, batch record design, deviation management, and CAPA.
  • Working knowledge of process characterization, design of experiments (DoE), and data-driven process optimization methodologies; familiarity with analytical methods used to characterize cell and gene therapy products (identity, potency, purity, safety testing).
  • Demonstrated ability to operate with a high degree of independence, define scope, manage competing priorities, and deliver results in a fast-paced, dynamic environment.
  • Strong technical writing capability with experience authoring SOPs, batch records, validation protocols, deviation reports, and regulatory submission content; excellent cross-functional communication and collaboration skills.

GeneFab is a contract development and manufacturing organization for cell and gene therapies, running cGMP facilities in Alameda, California that support programs from genetic design through commercial supply. The company manufactures ex vivo cell therapies such as CAR-T, TCR-T, CAR-NK, Treg, and iPSC products, plus in vivo lentiviral vector gene therapies at suspension scales up to 200 liters, backed by synthetic biology, process development, analytics, and cell banking. What sets GeneFab apart is its co-development approach, pairing partners with staff who worked on the innovator side and integrating every function under one roof with real-time transparency. The goal is to remove the obstacles between promising science and the patients who need it.

Simplify's Take

What believers are saying

  • RegCell partnership expands U.S. clinical manufacturing for autoimmune Treg therapies.
  • GeneFab's May 2026 facility launch adds capacity for new customers immediately.
  • Cell-specific control products create higher-margin attach opportunities across future gene therapy programs.

What critics are saying

  • Bigger CDMOs like Thermo Fisher and Lonza pressure margins and win late-stage programs.
  • RegCell dependence exposes GeneFab if autoimmune Treg timelines slip beyond 2025.
  • If Alameda expansion and product adoption lag, GeneFab burns cash and stalls operations.

What makes GeneFab unique

  • GeneFab combines synbio design, CRDMO services, and GMP manufacturing in Alameda.
  • On May 4, 2026, GeneFab launched pre-validated promoters and drug-induced switches.
  • Its Alameda site offers seven GMP clean rooms and parallel manufacturing wings.
