Principal Scientist / Associate Director – Biotherapeutics Engineering

Xilio Therapeutics is a clinical-stage biotechnology company discovering and developing tumor-activated immuno-oncology (I-O) therapies with the goal of significantly improving outcomes for people living with cancer without the systemic side effects of current I-O treatments. The company is using its proprietary platform to advance a pipeline of novel, tumor-activated clinical and preclinical I-O molecules that are designed to optimize their therapeutic index by localizing anti-tumor activity within the tumor microenvironment, including tumor-activated cytokines and antibodies (including bispecifics) and immune cell engagers (including tumor-activated cell engagers and tumor-activated effector-enhanced cell engagers).

SUMMARY: 

We are seeking a highly skilled and experienced Principal Scientist or Associate Director in Biotherapeutics Engineering to design and optimize biologics-based drugs, incorporating structural biology expertise as well as innovative computational methods. The successful candidate will have a strong background in structural biology, protein engineering and antibody discovery workflows. A solid background in applying machine learning techniques and molecular modeling to improve the biophysical and biological properties of biotherapeutics is highly desired. The candidate is expected to have expertise in leading cross-functional teams, generating key data, and driving projects from in silico concepts to in vivo proof of concept (PoC). If the successful candidate has management experience and continued interest in people management, the role may be offered as Associate Director, overseeing two direct reports.

Job Responsibilities:

  • Apply state-of-the-art in silico biotherapeutic engineering tools, CCG-MOE or Schrodinger-Maestro and/or others, to design and optimize biologics-based drugs.
  • Apply cutting-edge generative AI, machine learning and molecular modeling techniques to help identify novel binders and/or enhance the properties of biologics-based drugs, including target engagement, developability, immunogenicity, and protease specificity.
  • Perform biochemical and biophysical characterization of designed/engineered proteins to examine protein function as well as identify and develop structure-function relationships.
  • Lead or co-lead research project team, accountable for defining project strategy, ensuring effective execution of activities to meet project goals and timelines.
  • Represent Protein Engineering at project team meetings.
  • Support writing and reporting of key experiments in IND filings.
  • Capture detailed experimental information in electronic lab notebook (ELN) entries.

Skills, Qualifications, and Requirements:

  • PhD in Structural Biology, Chemical and Biomolecular Engineering or a related field and a minimum of 7-9 years of relevant post-graduate experience in industry or academic setting.
  • Strong expertise in biotherapeutics engineering, with a focus on computational methods for drug design and optimization is required.
  • Expertise in protein design and bioinformatics, including molecular modeling (homology modeling and molecular dynamics simulations) using in silico tools such as MOE, Maestro, NAMD, Schroedinger or VMD, etc. is required.
  • Strong analytical and problem-solving skills for computational analysis of protein, DNA, and mRNA sequences is required.
  • Demonstrated experience in applying machine learning techniques to improve the properties of biologics-based drugs is desired.
  • Knowledge of various generative AI/machine learning algorithms (RFDiffusion, Alphafold, Chroma, etc.) and experience in data mining using APIs is desired.
  • Experience in cloud computing and/or in writing code (SQL, R, python) for data wrangling and analytics is desired
  • Familiarity with electronic lab notebooks (such as Benchling) for data mining and analysis is desired.
  • Experience supervising direct reports or experience with CRO project management highly preferred.
  • Proven track record of leading cross-functional teams and successfully delivering projects from in silico concepts to in vivo proof of concept is preferred.
  • Excellent leadership and communication skills to effectively lead cross-functional teams and collaborate with stakeholders is required.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Xilio Therapeutics’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
