Job description

PsiThera is looking for an experienced drug discovery biologist with deep expertise in immune and inflammatory signaling to lead small-molecule and macrocycle discovery program teams from hit identification through development candidate (DC) nomination and IND submission. You’ll build and run the research plan for your programs, lead the project team that carries it out, and stay closely involved in the lab. The ideal candidate will strike a balance between program leadership and hands-on laboratory science. Your lab time will focus on high-impact creative work: establishing key assays, running decision-critical and mechanistic experiments, troubleshooting and training others. You may lead a small team of scientists as needed. This role suits a rigorous scientist who enjoys both designing the key experiments and getting a program across major milestones.

Key Responsibilities

Program team leadership:

Create and update research operating plans, including resource planning, budget management, risk assessment and contingency planning for your programs

Secure cross-functional alignment and organizational support for program plans

Lead multidisciplinary program teams and be accountable for meeting program goals, milestones and timelines

Define stage-gate success criteria and timelines for your programs, recommend resource allocation and go/no-go decisions to leadership

Manage CRO partnerships across all biology activities in support of your programs, including study design, execution, data quality and delivery to project teams

Strategic alignment and influence:

Shape the validation of targets and the scientific strategy for the immunology portfolio, advising leadership on opportunities and trade-offs

Engage key opinion leaders and external experts to pressure-test program hypotheses, align priorities with leadership and inform business and partnering decisions

Present program progress to senior leadership, and represent programs to prospective partners and at scientific conferences

Hands-on lab science:

Design and oversee hit finding campaigns (e.g., HTS and DEL), including hit triage and confirmation

Build and transfer fit-for-purpose assay cascades (biochemical, biophysical, cellular and whole blood) that support hit triage, SAR, target engagement and mechanism of action, to team members in-house and at CROs

Design and run in vitro pharmacology studies using primary human immune cells, whole blood and, where available, patient-derived samples, and design and oversee in vivo pharmacology and PK/PD studies in models of inflammation and autoimmunity, to link compound exposure to immune-cell function and disease-relevant outcomes

Contribute to the development and execution of translational biology biomarker strategies

Mentoring and capability building:

Build new in-house capabilities and technologies (e.g., assay platforms, human-cell and whole-blood systems) that serve multiple programs and keep PsiThera at the leading edge

Evaluate emerging technologies, CROs and academic or industry collaborations

Mentor scientists across the organization and constructively challenge scientific thinking

Qualifications

Required Qualifications:

PhD in Immunology, Molecular and Cellular Biology, or a related field with 12+ years of biotech or pharma drug discovery experience, or an MS with 16+ years of equivalent experience

Track record of advancing small molecules from hit identification to DC selection as project team leader or lead biologist

Hands-on experience in hit finding, including screening assay development, HTS or DEL campaigns, and hit triage and confirmation

Prior people management experience and demonstrated leadership of cross-functional project teams or workstreams

Hands-on expertise with primary human immune cells and whole blood, and in building assay cascades (biochemical, biophysical, cellular) for screening, SAR and mechanism-of-action studies

Broad knowledge of in vitro and in vivo models of inflammation and autoimmunity, with experience designing and interpreting in vivo pharmacology and PK/PD studies

Experience managing CRO collaborations

Scientific achievement shown through peer-reviewed publications and/or patents

Strong scientific rigor in generating, analyzing and presenting data to drive program decisions

Excellent written and verbal communication skills with scientific, executive and partner audiences

Preferred Qualifications:

Experience across multiple target classes and therapeutic areas

Experience working with clinical teams on translational research or biomarker strategy

Experience leading programs through IND submission
