Backed by over $100 million in funding from leading healthcare and technology investors, Proscia is at the forefront of this revolution. Joining Proscia means being part of a company at the cutting edge of healthcare innovation, where the possibilities are limitless. With the convergence of AI, precision medicine, and digital pathology, we're not just changing pathology-we're redefining what's possible in medicine.

About the Role

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.

Key Responsibilities

• Design, develop, test, and deploy scalable services and applications across the platform stack
• Build and maintain modern APIs, microservices, and web applications using TypeScript and Vue
• Collaborate within a high-performing Agile/Scrum team to define, estimate, and deliver impactful features
• Partner with engineering teams across Proscia to ensure interoperability, platform consistency, and shared architectural direction
• Contribute to frontend architecture and user experience improvements for complex, data-intensive applications
• Adopt an AI-first mindset by integrating modern intelligent tools into your engineering workflows for system navigation, configuration validation, and complex troubleshooting. We expect our engineers to already be leveraging these technologies as a core part of their professional practice.
• Demonstrated experience developing with large language models, agentic pipelines, or AI agents, along with a proven track record of applying advanced AI-assisted development techniques to solve sophisticated technical challenges.
• Fluency in prompt engineering, tool-use patterns, and the evaluation of AI systems, including the ability to identify necessary guardrails and ensure the reliability of AI-generated technical outputs.
• Participate in architectural design discussions and help drive best practices for scalability, observability, maintainability, and performance
• Improve developer productivity through automation, testing, CI/CD, and platform tooling
• Continuously evaluate emerging technologies, frameworks, and engineering practices to improve the platform

Required Experience

• 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

Desirable Experience

• Experience designing and scaling distributed systems in production environments
• Practical experience with microservices architecture and understanding associated trade-offs
• Experience building highly interactive or data-intensive frontend applications
• Familiarity with medical imaging, healthcare software, or regulated environments
• Experience working with large-file or high-throughput systems such as image processing or streaming platforms
• Understanding of event-driven architectures and messaging systems such as RabbitMQ, Kafka, or AWS SQS
• Experience with caching strategies, load balancing, API gateways, and performance optimization techniques
• Knowledge of database optimization strategies including indexing, partitioning, and connection pooling
• Experience with observability and monitoring tools for logs, metrics, and distributed tracing
• Familiarity with infrastructure as code tools such as Terraform or CloudFormation
• Experience participating in architectural reviews and translating technical designs into implementation plans
• Experience mentoring engineers and contributing to engineering culture and standards
