We are seeking a Senior Software Engineer with deep experience in scientific computing and biomedical informatics to lead the development and maintenance of software systems that support translational research. This role involves architecting and operating Python-based applications, managing cloud infrastructure, and working with biomedical data standards and machine learning models. You will work across multiple project streams as part of a cross-functional team that includes data scientists, researchers, and other engineers. A key aspect of this role is partnering directly with subject matter experts — scientists and researchers who understand the problem domain but may not have a technical background — to elicit requirements, translate research needs into well-defined technical solutions, and ensure that delivered software meets their real-world needs. The role requires a seasoned, self-directed engineer who can make sound architectural decisions, mentor junior team members, take ownership of technical components end-to-end, and deliver iteratively in a collaborative research environment. Key Responsibilities Architect, develop, and maintain Python-based scientific software, including client/server libraries, CLI tools, and containerized applications. Lead technical design decisions and establish best practices for code quality, testing, and deployment. Provision, deploy, monitor, and troubleshoot cloud services on AWS, including managing IAM roles, deployment pipelines, and S3 storage. Work with embedding models and vector databases to support NLP and semantic search capabilities. Design and maintain OMOP-compliant PostgreSQL databases, including vocabulary management and incremental data updates. Develop and maintain data migration and extraction scripts, with appropriate logging and verification for completeness. Conduct integration testing with external systems and evaluate model performance against large-scale datasets. Drive documentation, testing, and CI/CD workflows to support reliable software delivery. Engage directly with non-technical subject matter experts to gather requirements, clarify goals, and validate that delivered solutions align with research objectives. Translate high-level research needs into actionable technical specifications and development plans. Mentor junior engineers and contribute to a culture of technical excellence. Participate in and help facilitate standups, sprint planning, and cross-team review meetings across multiple project streams. Required Skills Qualifications 5+ years of professional experience in software development. Proficiency in Python for application development, scripting, and tooling. Demonstrated experience with machine learning models. Demonstrated ... (truncated, view full listing at source)
