Careers
“For the very first time in human history, biology has the opportunity to be engineering, not science.”
- Jensen Huang, President and CEO, NVIDIA
In drug development, massive amounts of data are generated, but turning that data into clear, real-world decisions is still incredibly difficult. CytoReason exists to close this data-decision gap.
We are building an AI platform that transforms petabytes of biological information into decision-ready disease models. Our work brings together science and engineering, with direct impact on how new treatments reach patients.
As a Cyto, you’ll work on complex, real-world problems alongside talented teammates from different disciplines, all focused on the same goal: to empower scientists with tools to make faster, more accurate decisions that ultimately lead to better outcomes for patients.
Senior Python Backend Developer
About The Position
We are seeking an experienced Senior Python Engineer to join our engineering team and drive the development of robust, scalable, and high-performance backend solutions. In this role, you will design and implement core services, optimize data workflows, and contribute to architecture decisions that support mission-critical applications. The ideal candidate brings deep expertise in Python, hands-on experience with distributed systems or data-intensive environments, and a passion for building reliable, production-grade software.
Responsibilities
- Enabling the adoption of next-generation orchestration tool – Nextflow
- Build software components to automate and reduce human work to annotate and design a model
- Contribute to and review frontend features in React, ensuring seamless integration with backend services.
- Help design and shape the product, working closely with product managers, bioinformaticians, and other stakeholders to align technical decisions with product goals.
- Mentor and support other developers through code reviews, internal discussions, clean code and technical guidance.
- Collaborate cross-functionally with product, data, and infrastructure teams to define requirements and deliver solutions.
- Write and maintain technical documentation and high-level designs
The Tech You’ll Work With:
- Frontend: React, TypeScript, Tailwind CSS

- Proactive mindset — someone who can take ownership, identify problems, and propose solutions.
Advantages
- Experience with Python or R for data-related workflows.
- Background in data-intensive systems or bioinformatics.
- Hands-on experience with modern frontend frameworks, preferably React.
- Familiarity with multi-cloud environments (GCP + AWS)
