About the Job

Requirements

  • Ph.D., M.D., or equivalent advanced degree in Immunology, Systems Biology, Computational Biology, or a related scientific discipline.
  • Extensive biotechnology or pharmaceutical experience in translational immunology, systems immunology, immune monitoring, or a closely related field, with level determined by scope and leadership experience.
  • Deep expertise in T-cell and B-cell biology, including activation, exhaustion, memory, depletion, reconstitution, and immune-mediated disease biology.
  • Demonstrated ability to integrate complex high-dimensional datasets across non-clinical and clinical studies and translate findings into program decisions.
  • Hands-on proficiency with multiple immunology data types, including single-cell sequencing and high-dimensional flow cytometry; ability to independently interrogate data is required.
  • Experience leading multidisciplinary scientific teams and influencing in a matrixed drug-development environment.
  • Excellent scientific judgment, communication, and presentation skills, including the ability to explain complex data to varied audiences.
  • Ability to thrive in a fast-paced, evolving biotechnology environment and balance strategic leadership with hands-on scientific contribution.
  • United States work authorization is required.

Responsibilities

  • Lead immunology-focused nonclinical and clinical translational strategy for ARM programs, ensuring analyses address program-critical biological and clinical questions.
  • Define immune-monitoring strategies designed to deepen understanding of mechanism of action, pharmacodynamic effects, clinical activity, durability, resistance, safety, and differentiated phenotypes.
  • Translate emerging science in T-cell engagers, CAR-T, autoimmune disease, immune reset, and immunotherapy into focused hypotheses and analytical plans for company programs.
  • Lead the identification and prioritization of key non-clinical and clinical questions that can distinguish ARM biology and performance from contemporary immunotherapy approaches, and collaboratively drive integrated evidence-generation strategies across translational, non-clinical, and clinical functions to establish platform differentiation.
  • Lead and perform integrated analyses of scRNA-seq, CITE-seq, TCR-seq, high-dimensional flow cytometry, phosphoflow, cytokine, proteomic, and/or spatial datasets.
  • Personally mine datasets and direct analyses performed by bioinformatics partners to identify immunological signatures, response patterns, and mechanistic insights.
  • Integrate nonclinical, translational, and clinical evidence into clear conclusions and recommendations for program teams and leadership.
  • Compare company datasets with relevant published and competitor datasets to identify differentiated mechanisms and translational opportunities.
  • Investigate mechanisms associated with efficacy, durability, resistance, cytokine release syndrome, immune exhaustion, B-cell depletion, and immune reconstitution.
  • Lead, mentor, and develop laboratory scientists and computational collaborators generating and analyzing immunology data.
  • Partner with Research, Translational Medicine, Bioinformatics, Biomarkers, Clinical Development, Clinical Operations, Regulatory, and program leadership to align sample strategy, assays, analyses, and decision timelines.
  • Communicate complex immunology findings through clear visualizations, scientific narratives, and decision-oriented presentations.
  • Guide external collaborators, consultants, and contract research organizations as needed, ensuring quality, scientific rigor, and timely delivery.
  • Contribute to regulatory documents, scientific communications, and external presentations, as appropriate.

Desired Qualifications

  • Experience with T-cell engagers, CAR-T or other cell therapies, bispecific biologics, autoimmune disease, hematologic malignancies, or immune-reset approaches.
  • Experience with CITE-seq, TCR-seq, phosphoflow, proteomics, spatial profiling, and integrated multi-omics analysis.
  • Experience designing clinical immune-monitoring strategies and supporting early clinical development.
  • Working knowledge of bioinformatics workflows and experience managing bioinformaticians or external computational partners.
  • Publication or presentation record demonstrating scientific leadership in translational or systems immunology.

About the Company

Janux Therapeutics

Clinical-stage biotech developing tumor-activated immunotherapies

Janux Therapeutics develops cancer immunotherapies that activate the immune system inside tumors to attack cancer while sparing healthy tissue. Its products are tumor-activated and use a proprietary platform masking technology to reduce toxic side effects and improve efficacy compared with traditional T cell engagers. The company advances drug candidates through clinical trials, aiming for regulatory approval and eventual commercialization, with revenue expected from partnerships, licensing, and the sale of approved therapies. Its lead program JANX007 is being evaluated in a Phase 1 trial (ENGAGER PSMA 01) for metastatic prostate cancer to assess safety and preliminary effectiveness.
