Job Overview

We are seeking a Principal Software Developer to lead the technical evolution of TEG Manager(R), our centralized hemostasis management platform that delivers real-time TEG 6s and TEG 5000 analyzer data to clinicians across operating rooms, ICUs, and emergency departments.

In this role, you will serve as a technical anchor for a cross-functional engineering team, driving architectural decisions and setting engineering standards for a mission-critical, regulated medical software system. As a principal-level contributor, you own the end-to-end architecture strategy for the TEG Manager platform - spanning device connectivity, data ingestion pipelines, and REST API design that integrates with hospital information systems and downstream clinical workflows. You will mentor engineers, collaborate with product and regulatory stakeholders to navigate regulatory software requirements, and champion engineering practices that balance velocity with the rigorous regulatory standards demanded in patient care environments.

What You’ll Do

• Define Architectural Strategy: Set the long-term technical roadmap, engineering standards, and core technology adoption (engine, backend, rendering).
• Drive Technical Governance: Act as the final authority on critical design decisions, establish quality gates, and manage performance budgets.
• Lead Hands-On Innovation: Prototype foundational systems, perform high-level code reviews, and solve high-risk architectural challenges.
• Mentor Team: Coach team members to foster a culture of technical rigor and continuous improvement.
• Risk Management: Identify and mitigate technical debt, performance bottlenecks, and architectural risks across the development lifecycle.
• Cross-Disciplinary Partnership: Align technical architecture with regulatory and commercial objectives.

What Will Make You a Great Fit

• Industry Veteran: 10+ years in software engineering, with 5+ years in a Principal or Architect role.
• Deep Expertise: Expert-level C# or other OOP languages such as Java/Python; RESTful APIs, Microservices, Domain-driven design, CI/CD, Event-driven architecture, Service-oriented architecture, High-availability, containerization, SQL and NoSQL.
• Cloud & Infrastructure Experience: AWS (ECS, EKS, RDS, Lambda, S3, SQS, CloudFormation), Terraform.
• Security & Compliance Experience: Cybersecurity/OWASP best practices, OIDC, SAML2, SOC2, ISO27001, HIPAA.
• Proven Track Record: Success in shipping multiple complex products with stable, maintainable architectures.
• Strategic Communicator: Ability to translate complex technical concepts for both engineers and executive leadership.
• Pragmatic Problem Solver: Balanced approach to solving immediate production needs while maintaining long-term architectural health.
• Innovation Focused: A passion for replacing legacy workflows with scalable, R&D-driven solutions.
