Its molecular, imaging, and clinical‑outcomes data support software that helps ensure a cancer patient’s report is right, complete, and on time. The Associate Software Engineer – Clinical Software Products contributes to the design, implementation, testing, and support of clinical software applications under the guidance of experienced engineers. Assignments are sequenced to build production experience: live clinical systems, regulated delivery practice, and cross‑functional product development. The team's toolchain includes advanced AI coding assistants and agentic workflows across design, implementation, and test generation. Characterization tests and golden‑master replay validation serve as the executable evidence that behavior holds. Onboarding is harness‑first: early assignments build or extend characterization tests, so the engineer learns current behavior through repeatable validation. Delivery runs on CI/CD, automated testing, application‑level observability, and risk‑based release governance aligned with current FDA Computer Software Assurance guidance. Representative technologies across the portfolio include Java, TypeScript, browser‑based application frameworks, server‑side JavaScript, and selected enterprise Java components. Interviews cover the specific assignment and technology stack. This individual‑contributor role reports to an Engineering Manager or Senior Engineering Manager within Clinical Software Engineering.
