About The Position

As a Senior Software Engineer, you’ll help build and evolve the software platform powering the future of digital pathology and medical imaging. You’ll work across the application stack — from scalable backend services and APIs to modern web applications and cloud-native infrastructure — delivering enterprise-grade software used in real-world healthcare environments. We’re looking for an engineer who is equally comfortable designing distributed systems, building intuitive user experiences, and leveraging modern AI-assisted development workflows. You’ll collaborate closely with cross-functional engineering, product, and operations teams to deliver highly scalable, reliable, and maintainable solutions. Our platform combines high-performance medical imaging, modern web technologies, microservices architecture, and cloud-native infrastructure to solve meaningful problems in healthcare and diagnostics. The ideal candidate has strong experience with TypeScript, Node.js/Deno, PostgreSQL, modern frontend development (Vue preferred), automated testing, and service-oriented architectures — along with a passion for building high-quality software and continuously improving engineering practices.

Requirements

5+ years of professional software engineering experience building production-grade applications
Strong experience with TypeScript and Node.js/Deno in enterprise application environments
Experience building and maintaining RESTful APIs and service-oriented applications
Experience developing modern web applications using Vue.js or comparable frontend frameworks such as React or Angular
Strong understanding of distributed systems, microservices, and API-driven architectures
Experience working with PostgreSQL in production environments, including ORM usage and direct SQL optimization
Strong automated testing experience using frameworks such as Vitest and Playwright
Experience building and deploying cloud-native applications in AWS or Azure
Prior experience with containerization and orchestration technologies such as Docker and Kubernetes
Experience with CI/CD pipelines and modern software delivery practices
Familiarity with Git-based workflows and Agile/Scrum development methodologies
Excellent problem-solving, communication, and collaboration skills
Passion for delivering high-quality, maintainable, and observable software systems
