Research Assistant II

JAX; Farmington (CT); On-site; USD 43,000 - 72,000; Full time

Job summary

The Jackson Laboratory for Genomic Medicine in Farmington, CT seeks a Research Assistant III to join the ARPA-H Cardioverse program. You will culture iPSC lines, generate iPSC-derived cardiomyocytes, and fabricate 3D engineered heart tissues.

Work includes functional assays, data management, and collaboration with computational teams building digital twin models. A Bachelor’s degree with relevant lab experience or a Master’s with fewer years are required; strong organization and independence are

Qualifications

• Bachelor’s degree in biology, biomedical science, bioengineering, or related field with 3+ years of relevant laboratory experience, or a Master’s degree with 1+ year.
• Hands-on experience with mammalian cell culture; iPSC culture and differentiation strongly preferred.
• Experience with cardiomyocytes, tissue engineering, or physiological assays such as contractility or calcium imaging is a plus.
• Comfort with high-throughput, multiwell workflows and meticulous record keeping.
• Experience with pharmacology or compound screening is a plus.
• Basic data analysis skills (Excel, Prism; R or Python a plus).

Responsibilities

• Culture, differentiate, and quality-control iPSC lines from genetically diverse donors, and generate iPSC-derived cardiomyocytes (iPSC-CMs) at scale.
• Fabricate 3D EHTs and microtissues in multiwell formats, following standardized protocols to ensure reproducibility across lines, batches, and operators.
• Perform functional assays on EHTs, including contractile force, kinetics, and calcium handling, and test compounds in dose-response studies for drug safety and efficacy.
• Prepare samples for multi-omic profiling (RNA-seq and single-cell assays) and imaging.
• Document experiments in detail, including metadata, line identifiers, and batch information, and follow data management practices that support computational modeling.
• Process and organize data, apply quality-control criteria, and work closely with computational collaborators who build the digital twin models.

Job description

## Research Assistant IIApply: Farmington, Connecticut: Full time: Posted 3 Days Ago: JR006351**Research Assistant III | Human Engineered Heart Tissue Platform, Cardioverse (ARPA-H)**Hinson Lab Farmington, CTThe Hinson lab at The Jackson Laboratory for Genomic Medicine and UConn Health is seeking a motivated, detail-oriented Research Assistant III to join our team on the ARPA-H Cardioverse program. Cardioverse aims to build digital twins of the human heart that predict drug safety and efficacy. Our role is to generate large-scale, high-quality experimental data from human engineered heart tissues (EHTs) made from iPSC lines that capture human genetic diversity. These data will train and validate predictive computational models.You will work in a collaborative, milestone-driven team that combines stem cell biology, tissue engineering, cardiac physiology, genome editing, and multi-omics. **Responsibilities*** Culture, differentiate, and quality-control iPSC lines from genetically diverse donors, and generate iPSC-derived cardiomyocytes (iPSC-CMs) at scale.* Fabricate 3D EHTs and microtissues in multiwell formats, following standardized protocols to ensure reproducibility across lines, batches, and operators.* Perform functional assays on EHTs, including contractile force, kinetics, and calcium handling, and test compounds in dose-response studies for drug safety and efficacy.* Prepare samples for multi-omic profiling (for example, RNA-seq and single-cell assays) and imaging.* Document experiments in detail, including metadata, line identifiers, and batch information, and follow data management practices that support computational modeling.* Process and organize data, apply quality-control criteria, and work closely with computational collaborators who build the digital twin models.* Support genome editing of iPSC lines and, as needed, in vivo mouse studies that validate findings from the human tissue platform.* Maintain laboratory supplies, equipment, and protocols, and help train new lab members. **Qualifications*** Bachelor’s degree in biology, biomedical science, bioengineering, or a related field with [3+] years of relevant laboratory experience, or a Master’s degree with [1+] years.* Hands-on experience with mammalian cell culture; iPSC culture and differentiation experience strongly preferred.* Experience with cardiomyocytes, tissue engineering, or physiological assays such as contractility or calcium imaging is a plus.* Comfort with high-throughput, multiwell workflows and meticulous record keeping. Experience with pharmacology or compound screening is a plus.* Basic data analysis skills (Excel, Prism; R or Python a plus).* Strong organizational and communication skills, and the ability to work independently and in a team with tight timelines and defined deliverables.
