The world we want tomorrow is the one were building today. It starts with the culture at this company. It starts with you.

About Iso

Isomorphic Labs (IsoLabs) was launched in 2021 to advance human health by building on and beyond the Nobel-winning AlphaFold system. Since then, our interdisciplinary team of drug discovery experts and machine learning specialists has built powerful new predictive and generative AI models that accelerate scientific discovery at digital speed.

Our name comes from the belief that there is an underlying symmetry between biology and information science. By harnessing AIs powerful capabilities, we can use it to model complex biological phenomena to help design novel molecules, anticipate how drugs will perform and develop innovative medicines to treat and cure some of the worlds most devastating diseases.

We have built a world-leading drug design engine comprising AI models that are capable of working across multiple therapeutic areas and drug modalities. We are continually innovating on model architecture and developing cutting-edge capabilities to advance rational drug design.

Every day, and with each new breakthrough, were getting closer to the promise of digital biology, and achieving our ambitious mission to one day solve all disease with the help of AI.

Your mission

We are seeking a highly innovative and experienced Bioanalytical Lead to bridge the gap between our predictive AI design platform and wet-lab preclinical execution.

In this role, you will define the overarching bioanalytical strategy across our expanding portfolio, covering small molecules, advanced biologic formats, and Antibody-Drug Conjugates (ADCs) in both non-GLP and GLP environments. You will collaborate closely with the drug design teams, design robust bioanalytical assays, manage global Contract Research Organizations (CROs), and lead the logistical execution required to rapidly advance our candidates toward IND submission.

As the Bioanalytical Lead, you will serve as the technical expert for our diverse portfolio of computationally designed therapeutic candidates. As part of the preclinical development function, this is a high-impact leadership role responsible for building the bridge between Isomorphics AI-driven discovery engine and the effective execution of our robust preclinical strategies, alongside safety and DMPK. The successful candidate will be forward thinking, thrive in fast-paced, agile environment and ready to embrace Isos AI-first mindset and challenge the status quo. With a broad range of internal and external stakeholders, candidates will be expected to have exceptional communication and influencing skills.

Bioanalytical Strategy & AI Integration

Define and execute comprehensive bioanalytical strategies for small molecules, large molecules, and complex modalities (ADCs) from discovery through preclinical development covering both non-GLP and GLP environments.
Oversee the design, validation, and transfer of robust PK, PD, and immunogenicity (ADA) assays at external labs.
Collaborate with AI/machine learning scientists to integrate bioanalytical data back into predictive models, helping to continuously improve our platform's accuracy.
Lead biomarker assay strategies, utilizing both traditional approaches and AI-identified novel biomarkers to support preclinical proof-of-concept.

Global CRO Management & Logistics

Select, qualify, and manage a high-performing network of global CRO partners, ensuring rigorous data quality, strict timelines, and budget alignment.
Master complex global logistics, including international sample shipments, cold-chain management, import/export compliance, and stability tracking across borders to ensure data integrity.
Serve as the primary technical point of contact for CROs, troubleshooting complex assay anomalies rapidly.

Cross-Functional Leadership and Regulatory Authoring

Work seamlessly at the intersection of Drug Discovery, Translational Medicine, and Computational Biology to drive candidates into the clinic.
Author and review high-quality regulatory documents, specifically bioanalytical sections of Investigational New Drug (IND) applications and Investigator Brochures (IBs).
Represent the bioanalytical function in cross-functional project teams and during interactions with regulatory agencies (FDA, EMA, etc.).

Required expertise and experience

Ph.D. in Biochemistry, Analytical Chemistry, Pharmacology, or a related scientific discipline with 5+ years of biotech/pharmaceutical industry experience; OR a B.S./M.S. with 8+ years of equivalent experience.
Proven track record of leading bioanalytical strategies across multiple modalities (must include small molecules, biologics, and ADCs).
Deep understanding of GLP and non-GLP preclinical study regulations, FDA/EMA bioanalytical method validation guidelines, and ICH guidelines.
Technical & Logistical Expertise
Extensive experience with diverse analytical platforms (e.g., LC-MS/MS, LBA, flow cytometry).
Demonstrated success in biomarker assay development and validation.
Expert knowledge of global sample shipping logistics, biosafety regulations, and maintaining chain-of-custody for precious preclinical samples.
Experience writing bioanalytical sections for successful IND submissions.

Nice to have

Experience of generating reagent in collaboration with drug design teams
Experience of developing or using AI tools (LLM) to accelerate processes including reporting

Culture and values

We are guided by our shared values. It's not about finding people who think and act in the same way. These values help to guide our work and will continue to strengthen it.

Thoughtful
Thoughtful at Iso is about curiosity, creativity and care. It is about good people doing good, rigorous and future-making science every single day.

Brave
Brave at Iso is about fearlessness, but its also about initiative and integrity. The scale of the challenge demands nothing less.

Determined
Determined at Iso is the way we pursue our goal. Its a confidence in our hypothesis, as well as the urgency and agility needed to deliver on it. Because disease wont wait, so neither should we.

Together
Together at Iso is about connection, collaboration across fields and catalytic relationships. Its knowing that transformation is a group project, and remembering that what were doing will have a real impact on real people everywhere.

Creating an extraordinary company

We believe that to be successful we need a team with a range of skills and talents. We're building an environment where collaboration is fundamental, learning is shared and every employee feels supported and able to thrive. We value unique experiences, knowledge, backgrounds, and perspectives, and harness these qualities to create extraordinary impact.

We are committed to equal employment opportunities regardless of sex, race, religion or belief, ethnic or national origin, disability, age, citizenship, marital, domestic or civil partnership status, sexual orientation, gender identity, pregnancy or related condition (including breastfeeding) or any other basis protected by applicable law.

Hybrid working

Its hugely important for us to share knowledge and build strong relationships with each other, and we find it easier to do this if we spend time together in person. This is why we follow a hybrid model, and would require you to be able to come into the office 3 days a week (currently Tuesday, Wednesday, and one other day depending on which team youre in). If you have additional needs that would prevent you from following this hybrid approach, wed be happy to talk through these if youre selected for an initial screening call.
