At HAYA Therapeutics, we are pioneering a new class of programmable RNA-guided therapeutics that target the regulatory genome to reprogram disease-driving cell states. By decoding the causal biology of pathological cell states and the long-noncoding RNAs (lncRNAs) that regulate them, HAYA translates these insights into tractable therapeutic candidates designed to address disease at its source and restore cellular health. HAYA is advancing a broad pipeline of RNA-guided medicines for chronic, age-related diseases.
Recognized globally for our scientific innovation, HAYA has been named a 2025 Technology Pioneer by the World Economic Forum (WEF), selected for BioSpace's NextGen Bio Class of 2026, recognized as a 2026 Disruptive Pioneer by IDEA Pharma, and celebrated as one of the Top Innovative Companies in Switzerland for 2025. As a fast-growing biotech, we offer an entrepreneurial, science-driven environment where you’ll have a direct impact on shaping our pipeline and advancing RNA medicine
1. Purpose:
Execute preclinical cellular assays, tissue histology, nucleic acid extractions, and spatial transcriptomics protocols to generate high-quality experimental data supporting HAYA's functional genomics and lncRNA target validation pipelines.
2. Accountabilities
Primary Cell Culture & ASO Screening Execution
- ·Execute primary cell isolation, tissue culture, and cell line maintenance (including human and mouse fibroblasts, C2C12 cells, myoblasts, and satellite cells) to establish robust in vitro disease models.
- Perform compound treatments and antisense oligonucleotide (ASO) screening protocols (including GapmeRs and siRNA) across primary cell platforms to evaluate target knocking-down efficiency and therapeutic potency.
- Isolate and process RNA, DNA, and proteins from cellular and tissue specimens using standardized extraction techniques to prepare high-integrity samples for downstream molecular profiling.
- Tissue Histology & Spatial Transcriptomics
- Perform tissue processing, FFPE embedding, sectioning, and staining protocols (including immunohistochemistry and immunofluorescence) to quantify fibrotic markers and evaluate tissue morphology.
- Execute spatial transcriptomics and multi-omics assay workflows in alignment with functional genomics protocols to characterize spatial gene expression in target tissues.
- Capture and analyze fluorescence microscopy images across immunostained and spatial transcriptomic tissue sections to extract qualitative and quantitative cellular insights.
- Preclinical Model Support & Data Governance
- Support in vivo preclinical study workflows by assisting with tissue dissections and sample collection from skeletal mouse and disease models to supply downstream experimental workstreams.
- Maintain detailed, real-time Electronic Lab Notebook (ELN) records, SOPs, and experimental documentation to ensure absolute data traceability, reproducibility, and audit readiness.
- Synthesize, analyze, and present experimental dataset summaries to internal R&D project teams and scientific leadership to inform ongoing pipeline decision-making.
