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 Full Stack Tech Lead
About The Position
We’re looking for a Senior Full Stack Tech Lead with a strong backend focus (around 70% backend / 30% frontend) to join our growing platform engineering team.
You’ll serve as a technical lead, helping shape the architecture, scalability, and performance of our platform, while mentoring other developers and raising our engineering standards.
In this role, you’ll work across the stack — primarily with Nest.js on the backend and React on the frontend — to design, build, and optimize systems that power advanced data-driven applications. You’ll collaborate closely with product and research teams to translate ideas into robust, maintainable, and performant software.
Responsibilities
- Design and implement backend APIs using Nest.js, integrating with data layers and external systems.
- Contribute to and review frontend features in React, ensuring seamless integration with backend services.
- Architect scalable systems and drive performance improvements across services and infrastructure.
- 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
- Backend: Nest.js, Node.js, TypeScript
- Frontend: React, TypeScript, Tailwind CSS
- Data & Storage: LakeFS, PostgreSQL, BigQuery
- Cloud: Google Cloud Platform (GCP)
- Additional tools: Python (advantage), R (familiarity a plus, not required)
- CI/CD & DevOps: Docker, Kubernetes
Requirements
- 7+ years of experience as a full-stack or backend-focused developer.
- Proficiency in Node.js / Nest.js and experience with scalable API design.
- Strong understanding of distributed systems, performance optimization, and cloud architectures.
- Experience leading projects or mentoring engineers — you enjoy helping others grow.
- Hands-on experience with modern frontend frameworks, preferably React.
- Strong communication and planning skills, with the ability to provide technical input during project scoping.
- Track record of delivering efficiently in agile teams with shifting priorities.
- 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.
- Familiarity with multi-cloud environments (GCP + AWS).
