About the Role

Freenome is looking for engineers to help us develop software to combat cancer and other age-related diseases. You will work as part of an interdisciplinary team of engineers and scientists building end-to-end solutions for our clinical and R&D labs. As an early team member, you’ll take the lead on major projects and collaborate actively with our world-class team of engineers, scientists, designers, and product managers. You’ll build modern, responsive web UIs that are a pleasure to use for both our internal and external systems. Since we’re a small team, you’ll also have an opportunity to work on a broad range of projects at all levels of the stack and help shape the direction of the Engineering team at Freenome.

Freenome’s software systems provide the “nervous system” for the company by tracking sample analysis from start to finish, empowering and assisting lab technicians and scientists, and automating our growing collection of cancer-fighting robots. This system is built using modern web software development technologies and methodologies.


  • Develop rich, maintainable, modern web frontend for both internal and external systems
  • Collaborate with team members for code and design review
  • Work with scientists, designers, product managers, and other engineers to solve complex problems in the face of dynamism and uncertainty
  • Take a mindful, transparent, and humane approach to your work and your interactions with others

What We're Looking For

  • 5+ years hands-on experience building and shipping complex web applications
  • 3+ years of experience with React
  • BS, MS or Ph.D. in Computer Science, Engineering or related field, or equivalent training, fellowship, or work experience

About Freenome
Freenome is on a mission to empower everyone with the tools they need to detect, treat, and ultimately prevent diseases. 
By applying machine learning techniques to high quality multi-omics datasets covering various disease types, Freenome is developing blood tests to detect early-stage cancer and make treatments more effective. The company has raised $78 million from investors such as Andreessen Horowitz, Google Ventures, Polaris Partners, and Founders Fund.
Our Science
Freenome is building technology to gain an understanding of the body through several analytes derived from blood. These signals include cell-free DNA, methylation of cell-free DNA, cell-free RNA, circulating proteins, and immune profiling derived from thousands of prospective samples. By developing novel statistical learning methods and applying them to integrate various -omics datasets, Freenome is a leader in modeling specific biological mechanisms to capture disease dependent signatures such as gene expression, immune response, tumor burden, tissue of origin, and 3D chromatin structure. 
By building comprehensive discovery datasets and modeling critical biological systems, Freenome is learning what biological changes are present within the blood between a variety of different disease states including cancer, autoimmune disorders, infections, drug response, and aging. With the combination of Freenome’s datasets, cross-functional technical expertise, and mission to uncover the biological truth, we seek to positively change the lives of millions through the early detection and early treatment of disease.
Our Culture
Freenomers are technical but creative, visionary yet grounded, empathetic and passionate. We build teams around divergent expertise, which allows us to solve problems and uncover opportunities in unique ways. Freenomers are some of the most talented experts in their fields. Together we advance healthcare one breakthrough at a time. 
We value empathy, integrity, and trust in one another. That means embracing other’s perspectives, those of our coworkers, and those of the patients and communities we serve. It means knowing when to push and when to be quiet and listen. At Freenome we give each other the benefit of the doubt in the belief that we’re all working as a team toward the same goals. We conduct ourselves with integrity, empowering others to grow in a collaborative environment. 
Freenome explicitly prohibits any form of workplace harassment based on race, color, religion, gender, sexual orientation, gender identity or expression, national origin, age, genetic information, disability, or veteran status.
What does a successful person look like at Freenome?
Those who thrive at Freenome prioritize, manage, and execute their own goals in alignment with those of the company. They embrace our values of empathy, integrity, and trust, and hold themselves and their team accountable. They crave collaboration with brilliant minds from unfamiliar fields of study and believe that hiring and mentorship are fundamental to our success. Above all, they welcome and provide constructive feedback and criticism, trusting in the good intentions of others, and feel secure in the knowledge that embracing mistakes is the best way to learn and move on. For those who crave challenges, understudied problems, and the chance to see their work impact the lives of millions of people affected by cancer every day, Freenome is the place to be.
