Experimental Systems Intern

Experimental Systems Intern Location: Cambridge, MA Time commitment: Part-time, approximately 25–30 hours per week; schedule must include multiple in-person laboratory days Duration: 3–6 months, with the potential to transition into a full-time role based on performance, project needs, and mutual interest Level: Senior undergraduate or master's student Introduction Flagship Pioneering is a company that creates companies, building ground-breaking platforms that change the world. We are a brave and bold organization of creative- thinkers with insurgent mindsets and corporate-builders with incumbent expertise. What if... we could harness the power of data with AI to create breakthroughs and accelerate the creation of new technologies? This is the question that Flagship Pioneering seeks to explore with our latest AI-focused business unit. Our mission is to create, launch, and scale breakthrough ventures that transform how we live, work, and connect. We build companies from zero to one, with cutting-edge AI, exceptional user experience, and a strong vision to pioneer an AI-native future.

The opportunity

We are developing a new method to measure small molecule compounds using an advanced sensor platform. We are seeking a hands-on Experimental Systems Intern to help characterize its performance and establish a rigorous, repeatable experimental workflow. You will work closely with project leads to design experiments, build and qualify fixtures, execute controlled studies, and maintain a trustworthy record of each experimental run. The work sits at the intersection of chemistry, sensing hardware, and experimental design.

What you will do

Help design and execute controlled small molecule compounds sensing experiments. Build, iterate, and qualify experimental fixtures for headspace exposure, airflow, sample positioning, and environmental control. Prepare and run concentration-series, blank, repeatability, recovery, and interference experiments using defined analytes. Characte
