• Work across the stack to build APIs, contribute to backend services, and support infrastructure and deployment
• Take ownership of frontend quality, reusability, and long-term scalability
• Implement data visualization components, including omics (genomics, transcriptomics, proteomics) and other biomedical data
• Improve CI/CD pipelines, observability, and development workflows
• Share knowledge and mentor engineers through code reviews, technical guidance, and architectural decisions
