Position Summary

Reporting to the Head of Research & Technology, the Senior Director, Head of Immunology will be a key scientific and strategic leader driving cutting-edge immunology research for Marengo’s immune-redirecting therapeutics. This individual will:

• Own the in vitro assay discovery function, including mechanistic immunology, primaryimmune cell assays, and MoA workflows, computational immunology function,      and preclinical translation 
• Serve as a strategic thought leader in tumor immunology, T-cell biology, and immune-pathway interrogation.
• Guide the scientific direction from early mechanistic discovery through translational interface and IND-enabling phases.
• Lead and mentor a team of PhD scientists, fostering a highly collaborative, rigorous research culture.

Key Responsibilities

Scientific Strategy & Immunology Thought Leadership

• Serve as a key thought leader in tumor immunology and T-cell biology, generating hypotheses and guiding the scientific direction of platform and program efforts.
• Formulate mechanistic studies to deeply understand immune activation pathways and the T cell biology underlying Marengo’s therapeutic platforms.
• Stay at the forefront of emerging science and technologies in cellular immunology and immune-redirecting modalities.
• Evaluate opportunities for platform and pipeline expansion based on mechanistic insights and emerging preclinical and clinical data.

In Vitro Assay Platforms & Mechanistic Research 

• Build, optimize, and oversee all in vitro assays, including primary immune cell systems, co-culture models, functional readouts, mechanistic studies, and translationally aligned MoA workflows.
• Develop robust assay systems that enable clear interpretation of immune activation, T-cell dynamics, MoA, and relevant biomarkers.
• Ensure experimental rigor, reproducibility, and strategic alignment with program goals.
• Integrate mechanistic data with translational endpoints to inform program advancement and clinical hypothesis development.

Translational Immunology

• Collaborate with translational science and clinical teams to develop biomarker strategies and clinical assay plans.
• Interpret translational datasets to refine mechanistic understanding and align research hypotheses with early clinical development.
• Contribute scientific insight to IND-enabling packages and technical reports supporting advancement into first-in-human studies.

Project & Program Leadership

• Serve as a project lead on programs moving from early discovery toward candidate selection.
• Develop and implement research plans that advance programs through mechanistic characterization, lead optimization, and IND-aligned milestones.
• Partner cross-functionally with antibody discovery, protein engineering, in vivo pharmacology, and preclinical development to ensure integrated data flow and decision-making.

Data & Computational Integration

• Integrate computational immunology, transcriptomics, and other large-scale datasets (e.g., single-cell profiling) to drive mechanistic insight and prioritization.
• Align computational and data science workflows to wet-lab assays with computational pipelines and hypothesis generation.

External Scientific Engagement

• Support and pursue external collaborations with academic groups and industry partners that enhance mechanistic and translational immunology capabilities.
• Represent the scientific function in external meetings, collaborations, and due diligence discussions as needed.

Team Leadership

• Lead, mentor, and grow a team of PhD scientists; set scientific expectations, provide career development, and promote an inclusive and collaborative culture.
• Align team priorities with program needs and ensure effective cross-functional scientific communication.

Required

• PhD in Immunology, Cancer Biology, or a related field with 10+ years of postdoctoral/industry experience in immuno-oncology.
• Deep expertise in T-cell biology, tumor immunology, and immune-tumor interactions.
• Extensive experience with computational immunology, in vitro assay development,      primary immune cell assays, and mechanistic MoA elucidation.
• Proven success leading discovery-stage I/O projects from hypothesis generation through proof-of-concept.
• Demonstrated ability to synthesize complex biological datasets and convert insights into strategic research plans.
• Strong scientific leadership experience with direct management of scientists and/or cross-functional project teams.
• Excellent communication skills and the ability to drive alignment across research and development groups.

Preferred

• Experience with immune-cell-retargeting or multispecific antibody therapeutics.
• Familiarity with IND-enabling workstreams and regulatory-related scientific documentation.

· Experience overseeing or collaborating on in vivo immuno-oncology studies is a plus.
