Who We Are:
Calico (Calico Life Sciences LLC) is an Alphabet-founded research and development company whose mission is to harness advanced technologies and model systems to increase our understanding of the biology that controls human aging. Calico will use that knowledge to devise interventions that enable people to lead longer and healthier lives. Calico’s highly innovative technology labs, its commitment to curiosity-driven discovery science, and, with academic and industry partners, its vibrant drug-development pipeline, together create an inspiring and exciting place to catalyze and enable medical breakthroughs.

Position description:

Calico is seeking an intern to join the Parkinson’s Disease Initiative. To succeed, you will need to be an enthusiastic team player, detail-oriented, extremely organized and comfortable working on complex problems.  In this position you will develop a novel imaging-based experimental system to study 𝝰-synuclein dynamics in vitro and in living cells, focusing on its oligomerization and aggregation regulated by disease-relevant perturbation. The successful candidate will work closely with members of the Parkinson’s Disease Initiative and the imaging team to develop a labeling strategy for 𝝰-synuclein using codon expansion technology. 

Responsibilities: 

• Optimize a genetic code expansion approach to site-specifically label alpha synuclein with fluorophores
• Proof-of-concept implementation of the labeling system in cell culture
• Perform biophysical characterization of labeled synuclein using rotational diffusion methods fluorescence polarization and tumbling methods in vitro and in living cells
• Explore experimental perturbations to induce changes in synuclein trafficking, oligomerization, aggregation and clearance

Position requirements:

• Currently pursuing a PhD degree, in biophysics, cell biology, neuroscience or a related field 
• Experience working with fluorescence microscopy, flow cytometry
• Knowledge of physical modeling of biological processes, quantitative imaging analysis
• Familiarity with standard molecular biology and tissue culture methods
• Detail-oriented and organized
• Strong teamwork and communication skills
• Self-motivated with a “can-do” attitude
• Flexible, able to respond quickly to shifting priorities and able to multitask

Nice to have:

• Experience in genetic screening, codon expansion system, Parkinson’s disease

• Competitive compensation ($45 - $70/hour) and monthly living expenses stipend
  

Program Eligibility:

• Able to work in-person at our offices in South San Francisco
• Free for a consecutive period of 11-12 weeks in June, July, and August
• Not graduating before December 2026
  • Exception for students enrolling into a graduate degree program in Fall 2026
• Must be enrolled in a US university
• Must apply by application deadline: February 1, 2026.
