Role Summary
We are seeking a Director of Bioanalytical Sciences to build and lead the bioanalytical strategy supporting our biologics portfolio across human and preclinical species, including non-human primate (NHP) and rodent models. This individual will be responsible for overseeing (both internally and externally) the development, qualification, and validation of bioanalytical methods spanning pharmacokinetics (PK), receptor occupancy (RO), and related biomarker and pharmacodynamic (PD) endpoints. As a key technical and strategic leader, the Director will partner extensively with contract research organizations (CROs) to deliver high-quality, regulatory-compliant data that informs candidate selection, translational strategy, and IND-enabling and clinical programs.
Key Responsibilities
- Define and execute the analytical bioassay strategy for biologic programs across discovery, preclinical, and clinical stages, with emphasis on human, NHP, and rodent species.
- Lead the development, optimization, qualification, and validation of ligand-binding assays (e.g., ELISA, MSD, ECL) and flow cytometry–based methods for PK, PD, receptor occupancy, and target engagement to support both non-GLP and IND-enabling GLP studies.
- Direct the design and interpretation of DMPK and bioanalytical studies, integrating PK/PD and exposure data to support candidate selection and translational dose projection.
- Serve as the primary technical and relationship lead for CRO partnerships — selecting, onboarding, and managing external labs; reviewing protocols, validation plans, and data packages; and ensuring on-time, high-quality deliverables.
- Author and review bioanalytical sections of regulatory documents (IND, IB, study reports) and ensure methods meet GLP and current FDA/EMA/ICH M10 bioanalytical method validation guidance.
- Establish robust assay qualification and validation frameworks, including acceptance criteria, troubleshooting strategies, and lifecycle management.
- Collaborate cross-functionally with discovery biology, protein sciences, pharmacology, toxicology, clinical, and regulatory teams to align bioanalytical endpoints with program goals.
- As pipeline evolves, build and manage a focused internal team.
Required Qualifications
- PhD in immunology, biochemistry, pharmacology, analytical chemistry, bioengineering, or a related life-science discipline.
- More than 10 years of biotech/pharmaceutical industry experience in bioanalytical or DMPK development for biologics.
- Deep expertise in bioanalytical method development, qualification, and validation for large molecules across human and preclinical species (NHP and rodent).
- Demonstrated hands-on and strategic experience with PK, PD, and receptor occupancy assays, and with DMPK study design and interpretation.
- Strong, proven track record of partnering with and managing CROs to deliver regulated bioanalytical data — a must.
- Working knowledge of GLP and regulatory bioanalytical guidance (FDA, EMA, ICH M10).
- Experience managing and mentoring staff scientists including in a matrixed environment.
Preferred Qualifications
- Experience supporting IND filings and early clinical development for biologics.
- Familiarity with platforms such as MSD/ECL, Gyrolab, Simoa, and multiparameter flow cytometry.
- Experience integrating PK/PD modeling and translational data.
- Prior experience building or scaling a bioanalytical function in a fast-paced or AI-enabled environment.
Compensation
We offer a competitive compensation and benefits package, seeking to provide an open, flexible, and friendly work environment to empower employees and provide them with a platform to develop their long-term careers.

Get Access To All JobsTips for Finding Xaira Therapeutics Visa Sponsorship Jobs USA
Target roles that align with H-1B specialty occupation criteria
Xaira Therapeutics sponsors H-1B visas for scientific and research roles requiring specialized degree qualifications. Focus your application on positions in computational biology, machine learning for drug discovery, or biochemistry where a directly related degree is clearly required.
Canadian and Mexican candidates should highlight TN eligibility
Xaira sponsors TN visas in addition to H-1B, which is a faster and simpler path for qualifying Canadian and Mexican nationals. If you hold citizenship in either country and work in a TN-eligible scientific field, make that eligibility explicit in your application.
Understand the H-1B lottery before planning your timeline
H-1B sponsorship at Xaira is subject to the annual lottery, typically held in March. If you're on OPT or another status, confirm your authorization runway covers potential lottery delays and align your job search timeline with the April filing window.
Position yourself at the intersection of AI and life sciences
Xaira Therapeutics sits at the frontier of AI-enabled drug discovery. Candidates with backgrounds spanning machine learning, structural biology, or computational chemistry are the strongest fit for roles where visa sponsorship is most likely to be offered.
Research open roles through a verified sponsorship platform
Not every job posting makes sponsorship eligibility clear. Migrate Mate surfaces verified sponsors so you can filter by real sponsorship history, helping you confirm Xaira Therapeutics is actively sponsoring before you invest time in an application.
Prepare for a research-intensive interview process
Xaira Therapeutics evaluates candidates rigorously for scientific depth and technical fit. Come prepared to discuss your research contributions, methodologies, and how your expertise advances their therapeutic pipeline, interviewers expect substance, not just credentials.
Frequently Asked Questions
Does Xaira Therapeutics sponsor H-1B visas?
Yes, Xaira Therapeutics sponsors H-1B visas for qualifying scientific and research roles. The H-1B is the primary pathway for international candidates at the company. Because H-1B sponsorship is subject to the annual cap and lottery, candidates should plan their job search around the March registration window and confirm their current visa status allows for the transition.
What visa types does Xaira Therapeutics sponsor?
Xaira Therapeutics sponsors H-1B and TN visas. The H-1B covers the broadest range of international candidates, while the TN is available exclusively to Canadian and Mexican nationals in eligible scientific and technical occupations. Green Card sponsorship has not been a documented pattern at Xaira, so candidates seeking permanent residence pathways should discuss long-term intentions during the offer stage.
Which departments or roles at Xaira Therapeutics are most likely to receive visa sponsorship?
Sponsorship at Xaira Therapeutics is concentrated in highly specialized scientific and research functions, particularly roles involving computational biology, machine learning applied to drug discovery, structural biology, and related fields. These positions require advanced, field-specific degrees that satisfy H-1B specialty occupation criteria. Candidates in generalist or administrative functions are far less likely to be sponsored.
How do I find open visa-sponsored jobs at Xaira Therapeutics?
The most reliable approach is to search Migrate Mate, which tracks verified sponsoring employers and filters roles by visa type. Because Xaira Therapeutics operates in a highly specialized research niche, openings can be limited and competitive. Setting up job alerts on Migrate Mate for Xaira specifically ensures you're notified as soon as a sponsored role becomes available, rather than checking manually.
How do I approach the application timeline for H-1B sponsorship at Xaira Therapeutics?
Start your outreach well before the March H-1B registration window. Xaira Therapeutics would need to register your petition by mid-March for a potential October 1 start date. If you're on OPT, confirm your expiration date allows time for a cap-gap or status change. Raising sponsorship willingness early in conversations, ideally before the final interview stage, prevents late-stage surprises for both sides.
