Responsibilities

• Design, build, and validate novel lentiviral vectors for in vivo cell therapy applications.
• Perform hands-on construct designs, viral genome optimization, viral envelope pseudotype engineering and vector assembly.
• Design, plan and execute in vitro and in vivo experiments to assess transduction efficiency, specificity, expression durability, and safety profile of novel in vivo LVVs.
• Develop and run assays for titer, potency, biodistribution, integration site analysis, and immunogenicity in collaboration with analytics partners.
• Apply literature mining, public datasets, and personal expertise to generate innovative, testable hypotheses and prioritize vector concepts.
• Implement rigorous experimental design, statistical analysis, and documentation to ensure reproducibility, traceability, and data integrity.
• Collaborate extensively with discovery teams across AZ including payload biology, bioinformatics, and nonclinical to align vector designs with product requirements.
• Contribute to platform development by creating screening workflows, model systems, and standardized protocols for vector performance.
• Present findings, risks, and recommendations in working groups and project meetings and drive decisions through clear data storytelling.
• Support IP generation by contributing to invention disclosures and sharing FTO considerations with the IP team.

Essential Skills/Experience

• PhD in molecular biology, virology, bioengineering, or related field with 4+ years of postdoctoral experience in academia or industry.
• Demonstrated expertise in viral vectors and virology with a strong track record in viral vector design, engineering, and characterization for gene therapy.
• Proficiency in molecular biology techniques for vector construction, promoter and regulatory element engineering, and payload optimization.
• Experience in protein and antibody (scFV and VHH) engineering or envelope/pseudotype modification to tune tropism, entry, and transduction profiles.
• Hands-on familiarity with in vitro cell culture assays and in vivo models for vector evaluation including transduction assays, dose–response, durability studies, and safety readouts.
• Strong hands-on competence with quantitative analytics such as flow cytometry and qPCR/ddPCR.
• Ability to design rigorous experiments, apply statistics, and interpret complex datasets to drive go/no-go decisions.
• Strong collaboration and communication skills to operate as a backbone member of cross-functional working groups and align discovery efforts with product goals.
• Evidence of innovation through publications, presentations, or open-source contributions and comfort leveraging literature and public data to ideate and de-risk.
• Organized, proactive, and product-focused mindset with the ability to manage multiple experiments, meet timelines, and maintain high-quality documentation.
• Commitment to being fully hands-on at the bench while mentoring peers and contributing to platform and program deliverables.

Desirable Skills/Experience

• Strong preference for lentiviral vectors.
• Practical understanding of safety risks and mitigations for LVV including insertional mutagenesis, off-target transduction, immunogenicity, and RCL testing.

When we put unexpected teams in the same room, we fuel bold thinking with the power to inspire life-changing medicines. In-person working gives us the platform we need to connect, work at pace and challenge perceptions. That's why we work, on average, a minimum of three days per week from the office. But that doesn't mean we're not flexible. We balance the expectation of being in the office while respecting individual flexibility. Join us in our unique and daring world.

The annual base pay for this position ranges from $113,902 – $170,854 USD Annual. Hourly and salaried non-exempt employees will also be paid overtime pay when working qualifying overtime hours. Base pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience. In addition, our positions offer a short-term incentive bonus opportunity; eligibility to participate in our equity-based long-term incentive program (salaried roles), to receive a retirement contribution (hourly roles), and commission payment eligibility (sales roles). Benefits offered included a qualified retirement program [401(k) plan]; paid vacation and holidays; paid leaves; and, health benefits including medical, prescription drug, dental, and vision coverage in accordance with the terms and conditions of the applicable plans. Additional details of participation in these benefit plans will be provided if an employee receives an offer of employment. If hired, employee will be in an “at-will position” and the Company reserves the right to modify base pay (as well as any other discretionary payment or compensation program) at any time, including for reasons related to individual performance, Company or individual department/team performance, and market factors.
