At Parallel Bio, we are leveraging the human immune system to unlock safer, more effective drugs. We believe immunotherapies are the future of medicine, but their discovery is hindered by outdated models that fail to capture the complexity of the human immune system.
Our platform overcomes these challenges by combining best-in-class human immune organoids with massive scale and advanced computational methods, including AI and machine learning. This allows us to generate unprecedented, population-scale insights into human health and disease.
We can rapidly discover new drugs that we know will work in patients from the start and understand how they will perform across an entire population—something not possible with today's technology. This knowledge will allow us to engineer therapies that will work for as many people as possible, ensuring a safe and effective cure for everyone.
We are a fast-paced, venture-backed company at a pivotal moment of growth. Join us on our journey as we create new tools to push the boundaries of what is possible.

The Role Parallel Bio is building the foundation model for human drug response, trained on patient-derived organoid data at unprecedented scale. We are a multi-site team operating automated wet labs, managing PHI under HIPAA, and scaling rapidly.
We are looking for our first dedicated IT hire to own corporate IT end-to-end across identity, devices, SaaS platforms, network infrastructure, and end-user support. This is a hands-on role today with a clear path toward building the IT function as we scale.
You will inherit a functioning stack along with active vendor engagements for network infrastructure and endpoint/identity security. Your job is to operationalize what exists, rationalize what is fragmented, and own these vendor relationships with an eye toward evolving our approach as the company grows.
This role is for someone who can troubleshoot a WiFi issue in the morning, negotiate a vendor contract at lunch, and draft a multi-site IT roadmap in the afternoon. You should be organized, technically capable, and comfortable operating across strategic and tactical work.
