Position Summary
We are seeking a motivated Senior Principal Scientist with deep expertise in viral and non-viral vector and genetic construct design to drive next-generation gene delivery strategies in a fast-paced, collaborative, and delivery-focused clinical translation research environment. This role will lead the design of lentiviral vectors, transposon-based architectures, and mRNA-based delivery systems, for applications spanning functional genomics, cell engineering, and therapeutic development.
The ideal candidate combines rigorous academic training with a practical engineering mindset, capable of translating biological objectives into high-performance genetic constructs.
Job Responsibilities
  • Lead innovation in the design, construction, and optimization of complex plasmid systems for lentiviral vectors, including transfer, packaging, and envelope components and multi-gene cargos.
  • Lead engineering of novel self-inactivating (SIN) lentiviral backbones, resolving cross-element tradeoffs among LTRs, ψ (psi) packaging signal, RRE, cPPT/CTS, and WPRE.
  • Lead the design and implementation of innovative complex transposon-based systems, including donor vector architecture (ITRs/TIRs), multi-cargo optimization, nuclear localization and genomic integration and transposase delivery strategies.
  • Develop novel site-specific CRISPR/transposon integration designs.
  • Architect complex expression systems and establish design strategies for constitutive, inducible, cell-type-specific, and multiplexed gene expression for ex vivo and in vivo T cell engineering including CRISPR/Cas9 based delivery of mulit-gene payloads
  • Define and resolve platform constraints-including payload size, recombination risk, silencing, and integration profiles-and recommend fit-for-purpose delivery approaches.
  • Lead development and optimization of innovative mRNA delivery constructs, integrating UTRs, codon usage, modified nucleotides, cap structures, and poly(A) tail configurations to maximize stability and translation.
  • Provide cross-functional technical leadership across vector production, cell engineering, and functional validation teams to drive construct-design decisions and iteration.
  • Mentor and provide technical guidance to Scientists, Research Associates, and other laboratory personnel.
  • Integrate sequencing, expression, and functional data to diagnose complex packaging, delivery, or expression failures and direct corrective strategies.
  • Establish and oversee standards for design documentation, sequence maps, construct libraries, and design traceability.
  • Shape strategic direction by assessing emerging delivery modalities and synthetic biology approaches and recommending platform adoption or investment.

Education
  • PhD in Molecular Biology, Virology, Genetic Engineering, Synthetic Biology, or related field.

Experience
  • 10+ years of relevant postdoctoral and/or industry experience in gene delivery systems or advanced molecular cloning.
  • Proven track record of designing and implementing complex genetic constructs.

Required Technical Expertise
  • Deep knowledge of lentiviral vector biology and design, including multi-plasmid systems and safety features.
  • Expertise in plasmid architecture, including promoters (e.g., EF1α, CMV, CAG), enhancers, insulators, and post-transcriptional regulatory elements.
  • Experience designing mRNA constructs for transient expression and delivery optimization.
  • Strong understanding of transposon systems and stable integration strategies.
  • Proficiency with DNA design software and sequence analysis tools (e.g., SnapGene, Benchling, Geneious).
  • Familiarity with gene expression tuning, including codon optimization, RNA stability, and translational efficiency.
  • Ability to interpret NGS and Sanger sequencing data for construct validation.

Preferred Qualifications
  • Experience with CRISPR/Cas systems, including multiplexed guide RNA architectures and delivery strategies.
  • Background in cell therapy, gene therapy, or genome engineering applications.
  • Familiarity with non-viral delivery systems (e.g., LNPs for mRNA).
  • Exposure to scale-up considerations and translational/regulatory frameworks.
  • Experience working in highly collaborative, interdisciplinary environments.

Knowledge, Skills and Abilities
  • Engineering-driven approach to biological problem solving
  • High attention to detail in sequence-level design
  • Ability to balance innovation with practical constraints
  • Strong communication skills across scientific disciplines
  • Self-directed with a bias toward execution in a fast-moving environment

Licenses and Certifications
Working Conditions/Physical Demands
  • Operates at the interface of academia and biotech: hypothesis-driven research combined with milestone-oriented execution
  • Access to cutting-edge genomic technologies and collaborative expertise
  • Emphasis on rapid iteration, data-driven decision making, and translational impact
