Senior Software Engineer (Applications), Full Stack

Many structural heart patients suffer from heart failure with limited options. Our Implantable Heart Failure Management (IHFM) business's AI, Product and Platforms organization is at the forefront of addressing these unmet patient needs through pioneering technology that enables early, targeted therapeutic intervention. Our innovative solutions are not just transforming patient care but also creating a unique and exciting environment for our team members. It is our driving force to help patients live longer and healthier lives. Join us and be part of our inspiring journey. At Edwards Lifesciences, the Implantable Heart Failure Management (IHFM) AI, Product and Platforms organization designs and builds the software and data products that clinicians and patients depend on. As a Senior Software Engineer (Applications), Full Stack, you own the application and service architecture for a web product area, build the patterns and shared components others follow, and are first in line for the production health of what you ship. Based in Irvine, CA, you'll join a high-impact medtech innovation hub in the heart of Orange County, collaborating in person with cross-functional teams to shape patient-focused technology. How you'll make an impact:

• Product-area architecture. Design and own the application architecture for a web product area: state management, routing, data fetching against Platform APIs, rendering strategy, design system implementation, and experimentation.
• APIs and security. Define and document the API contracts your product area needs from Platform, consume them through the Platform API gateway, and implement client-side authentication and authorization flows (OAuth 2.0, OpenID Connect, SSO); contribute server-side code to Platform-owned services where your area requires it.
• Performance and reliability. Own customer-facing performance and quality metrics, such as Core Web Vitals, API latency, and error rates, and build the fixes that move them.
• Cloud deployment. Design and deploy your web applications on the cloud (AWS or GCP) using containers, CI/CD, and infrastructure as code, within the standards and security controls that Platform and DevSecOps own.
• Patterns and modernization. Build the patterns and shared components others follow, review designs and code against them, and drive targeted modernization in your area, such as Angular to React and BFF to Platform APIs.
• Design control. Produce the architecture documents, verification tests, and traceability for your area's design outputs, and understand how they contribute to the Design History File under IEC 62304.
• Production ownership. Serve as a trusted on-call lead for web surfaces, lead root-cause analysis, and resolve complex production issues affecting clinicians and patients, including issues that trace into Platform-owned services you contribute to.
• Mentorship. Mentor P1 and P2 engineers, review their designs and code, and participate in hiring. What you'll need (Required):
• Bachelor's degree in computer science, software engineering, or related field plus four years of experience -or- Master’s degree plus three years of experience.
• Deep proficiency in React or Angular with TypeScript and working proficiency in a server-side stack such as Node.js, Python, Java, Go, or Rust.
• Demonstrated experience designing application architecture and API contracts, including state management, data fetching, and integration with internal and third-party systems.
• Experience deploying and operating applications on a cloud platform (AWS or GCP), including CI/CD and containers.
• Experience owning the performance, reliability, and production health of end-user-facing software.
• Strong communication skills, including effective collaboration with distributed teams across time zones, and the ability to set standards within a secure software development lifecycle (SSDLC), including CI/CD and automated testing. What else we look for (Preferred):
• Experience in medical device software (SaMD), or other regulated classes of device software, under IEC 62304, ISO 13485, and FDA design controls.
• Experience leading a frontend modernization, such as Angular to React.
• Experience with infrastructure as code (Terraform, CloudFormation, or CDK) and container orchestration (Kubernetes).
• Experience with design system implementation and design tokens, including tooling such as Figma and Tokens Studio.
• Familiarity with EMR / EHR integration via HL7, FHIR, or IHE.
• A cloud certification, such as AWS Solutions Architect or Developer, or a GCP equivalent.
• Familiarity with usability engineering and human factors (IEC 62366-1). Aligning our overall business objectives with performance, we offer competitive salaries, performance-based incentives, and a wide variety of benefits programs to address the diverse individual needs of our employees and their families.
