Sr Software Engineer - .NET

As a Senior Software Engineer, you will lead the design and development of high-performance, scalable enterprise web applications that increasingly leverage cloud technologies. This position emphasizes hands-on software engineering; building, architecting, and modernizing systems, as the top priority.

While cybersecurity and product security experience are required, your primary role will be to develop software solutions, support migration from on-premise systems to the cloud, and drive engineering best practices across the team. You will collaborate in a dynamic Agile environment, helping shape both technical decisions and the future state of healthcare technology.

Primary Duties & Responsibilities

Software Development & Cloud Engineering (Primary Focus)

• Lead the design, development, and deployment of enterprise-level web applications using modern .NET technologies (.NET Core/Framework, WPF) and JavaScript frameworks (React, Angular, Vue.js).

• Architect and support migration projects to cloud environments (Azure, AWS, or similar), including re-platforming and modernizing legacy on-premise applications.

• Build and optimize RESTful and SOAP API services and ensure seamless integration with internal and cloud-hosted systems.

• Develop and implement responsive, user-centric front-end applications using HTML5, CSS3, and styling libraries such as Bootstrap, Tailwind, or MUI.

• Work with containerization and deployment tools (Azure Container Apps, Docker, Kubernetes) and cloud-based CI/CD pipelines to deliver production-ready software.

• Write effective unit, integration, and automated tests to ensure high-quality software delivery.

• Contribute to software architecture and design decisions, ensuring scalability, maintainability, and performance in hybrid on-prem/cloud environments.

• Mentor junior developers and promote engineering best practices across the team.

Cybersecurity & Product Security (Supporting)

• Collaborate with product development teams to incorporate cybersecurity considerations into system designs.

• Support the development of product cybersecurity threat models and vulnerability assessments.

• Help maintain and update cybersecurity risk management documentation and participate in security reviews.

• Stay current on cybersecurity best practices, ensuring developed software aligns with organizational security standards.

Minimum Education & Experience

• Bachelor’s degree in Computer Engineering, Computer Science, Software Engineering, Electrical Engineering, or Cybersecurity (Master’s Degree preferred).

• 5+ years of experience in software engineering, with significant contributions to enterprise web application development.

• Hands-on experience with .NET Core/Framework, C#, and modern JavaScript frameworks.

• Experience supporting or leading a migration from on-premise infrastructure to cloud (Azure, AWS, or similar).

• Familiarity with product security concepts, including threat modeling and secure coding practices.

Preferred Skills & Competencies

• Proficiency in modern .NET, WPF, and C# development.

• Strong experience building RESTful and GraphQL APIs and optimizing database performance.

• Knowledge of cloud-native services, serverless computing, and hybrid architectures.

• Familiarity with Docker, Kubernetes, and CI/CD pipelines.

• Strong understanding of cybersecurity principles and defensive coding practices.

• Excellent communication, collaboration, and problem-solving skills.
