CareDx offers products, testing services, and digital healthcare solutions along the pre- and post-transplant patient journey, and is the leading provider of genomics-based information for transplant patients.\nThe Data & AI Engineer II will develop analytical applications, data pipelines, and AI-powered capabilities that support clinical research, statistical analysis, and data-driven decision-making. This role helps transform research workflows, statistical analyses, and machine learning models into reliable, secure, and user-facing software. The engineer will collaborate with data scientists, statisticians, engineers, clinicians, and product stakeholders to productionize analytical workflows, translate R-based analyses into maintainable Python, and deliver applications for internal and external users. The engineer will also contribute to AI-powered features that analyze structured and unstructured data, extract information from documents, synthesize analytical results, and help users interpret scientific and clinical information. Success in this role requires strong software engineering fundamentals, curiosity, and the ability to independently deliver well-defined components and features with support on more complex technical decisions.\nResponsibilities:\nDevelop and maintain analytical applications using tools and frameworks such as Python, Streamlit, Plotly, Dash, and Django.\nOwn the implementation, testing, deployment, and maintenance of well-defined application features and data workflows.\nProductionize statistical models and machine learning workflows developed by data scientists and statisticians.\nTranslate and refactor R-based research and analytical workflows into maintainable, tested Python code.\nBuild and maintain data pipelines that support clinical data processing, analysis, visualization, and reporting.\nDevelop interactive applications that enable data exploration, visualization, and decision support.\nIntegrate applications with relational databases, APIs, analytical outputs, documents, and other structured and unstructured data sources.\nContribute to AI-powered application features using techniques such as structured information extraction, retrieval-augmented generation, tool or function calling, and multi-step workflows.\nImplement validation, grounding, logging, traceability, and human-review mechanisms for AI-generated outputs.\nCollaborate with scientists, clinicians, product stakeholders, and senior engineers to translate requirements into practical technical solutions.\nParticipate in technical design discussions and document implementation decisions, assumptions, and tradeoffs.\nWrite reliable, readable, and testable code using established engineering patterns and team standards.\nParticipate in code reviews and incorporate feedback to improve implementation quality and technical judgment.\nMonitor, debug, and improve application performance and reliability across data, model, AI, and application layers.\nFollow security, privacy, and compliance requirements for sensitive healthcare data, including HIPAA-aligned practices.\nContribute to shared components, documentation, development tools, and engineering process improvements.\nCommunicate progress, risks, dependencies, and technical challenges clearly and proactively.\nQualifications:\nEducation: Bachelor’s or master’s degree in Computer Science, Data Science, Engineering, Biostatistics, or a related quantitative field, or equivalent practical experience.\nExperience: 2+ years of experience in data engineering, backend engineering, full-stack development, analytics engineering, or a related role.\nStrong proficiency in Python for data analysis and software development.\nExperience working with statistical analysis, data science, or machine learning workflows.\nExperience transforming prototype, research, or analytical code into maintainable software.\nExperience building analytical applications using Streamlit, Plotly, Dash, or similar technologies.\nExperience developing backend services or web applications using Django, FastAPI, Flask, or a similar framework.\nExperience building and maintaining data pipelines that integrate multiple data sources.\nFamiliarity with relational databases, SQL, APIs, and common data formats.\nExperience or demonstrated applied knowledge in at least one modern LLM capability, such as retrieval-augmented generation, structured extraction, tool calling, or agentic workflows.\nUnderstanding of core production considerations for AI systems, including grounding, hallucination mitigation, output validation, security, latency, cost, and human oversight.\nExperience with version control and collaborative development practices, including Git, branching, pull requests, and code reviews.\nExperience writing automated tests and debugging applications across multiple technical layers.\nAbility to independently deliver well-defined features while seeking guidance when requirements or technical risks are unclear.\nStrong written and verbal communication skills.\nHonest and transparent approach to feedback, collaboration, and accountability.\nPreferred Qualifications:\nExperience in healthcare, biotechnology, clinical research, or another regulated environment.\nExperience working with sensitive or protected healthcare data.\nFamiliarity with HIPAA-aligned application and data-handling practices.\nExperience with Azure, Databricks, or comparable cloud and data platforms.\nFamiliarity with CI/CD practices and automated testing tools such as pytest.\nExperience with pandas, NumPy, scikit-learn, statsmodels, or similar data science libraries.\nExperience deploying or supporting production web applications.\nExperience using modern AI-assisted software development tools, such as Codex or similar coding agents, for development, testing, debugging, and documentation.\nDomain knowledge in biological medicine, healthcare, or clinical data.\nExperience communicating technical work to scientific or clinical audiences.\nAdditional Details: \nEvery individual at CareDx has a direct impact on our collective mission to improve
