Scientist, Computational Vaccine Design

Position Summary

We are seeking a Scientist to join a dynamic team applying computational and data-driven approaches to design novel antigens and evaluate vaccine responses. At Apriori Bio we have built our biology-enabled AI/ML platform Octavia to map viral fitness landscapes predict immune escape trajectories and design vaccines to elicit an optimal protective response to future challenges. The successful candidate will contribute to the development and application of computational methodsincluding structural modeling machine learning and statistical inference that build on Octavia insights to support the companys vaccine design efforts. Experience working with protein engineering and immunological datasets is valuable as is interest or training in high-throughput functional genomics virology or vaccinology.

The Scientist will work closely with both computational and experimental colleagues to interpret results generate hypotheses and support antigen design. This role is ideal for scientists eager for a unique opportunity to learn and innovate within an interdisciplinary fast-paced startup environment.

Key Responsibilities

• Use high-dimensional datasets (e.g. mutational scanning NGS-based phenotypic screens) and computational approachesincluding structural modeling sequence analysis and machine learningto support antigen and immunogen engineering
• Apply and refine computational models that integrate screening data with structural and sequence-based features to guide biomolecule engineering
• Generate hypotheses and design analyses that inform evaluation of novel immunization strategies (in partnership with experimental teams)
• Identify evaluate and curate external datasets relevant to vaccine design and antigen optimization
• Develop reproducible computational tools and pipelines for data-driven product design that can be integrated into broader platform workflows
• Collaborate with engineers computational scientists and experimentalists to execute project goals and ensure smooth integration of computational findings
• Work with immunology and characterization teams to interpret vaccine immunogenicity using next-generation immune monitoring and antibody profiling tools
• Clearly communicate results and insights to colleagues across scientific and cross-functional teams
• Tackle difficult scientific problems with creativity and resilience while iterating quickly as new data emerges
• Take ownership of complex open-ended scientific questions driving analyses forward through ambiguity while balancing speed rigor and collaborative problem-solving

Basic Qualifications

• Ph.D. in bioengineering immunology computational biology or a related field (or equivalent research experience)
• Experience applying data-driven protein engineering methods to predict and affect protein function including structural and sequence-based machine-learning approaches
• Experience or training in antigen design leveraging vaccine immune response readouts
• Solid statistical and quantitative foundation with the ability to translate complex biological datasets into actionable insights
• Strong scientific programming skills (Python preferred) and familiarity with best practices in reproducible scientific computing
• Experience working with high-throughput biological data or NGS-based assays including modeling and statistical analysis
• Experience using version control and collaborative coding workflows

Preferred Qualifications

• Experience in vaccine design
• Experience with deep learning approaches
• Exposure to antibody characterization immune profiling or immune repertoire analyses
• Experience with NGS data pipelines from processing to interpretation
• Familiarity with cloud or distributed computing environments
• Familiarity with storage analysis and transformation of large tabular datasets and relational databases
• Laboratory experience in molecular biology biochemistry or immunology (a plus not required)
