• Establish engineering standards for code quality, testing, observability, security and performance; improve development practices and tooling.
• Collaborate with product, design, machine learning, infrastructure, QA and regulatory teams to deliver reliable software that protects data integrity and patient data and meets regulated medical device requirements, including design controls and validation.
• Mentor senior and mid-level engineers, develop technical leadership and contribute to hiring and onboarding.
• Represent engineering with customers, partners and stakeholders, explaining technical concepts to non-experts.

Required Qualifications

• BS in Computer Science, Software Engineering or a closely related technical field, or equivalent practical experience.

- Backend: Python applications and APIs using Django or FastAPI, data modeling, relational databases such as PostgreSQL, and distributed or event-driven systems.
- Frontend: complex, performant web applications using modern JavaScript frameworks such as Vue or React, including state management, frontend architecture and UX quality.

• Strong foundations in data structures, algorithms and system design.
• Hands-on experience building and operating cloud systems; AWS is preferred.
• Ability to influence technical decisions through clear writing, sound judgment and collaboration.
• Excellent communication skills and effectiveness with distributed teams and non-technical stakeholders.

Preferred Qualifications

• Software development experience in regulated environments, such as FDA, IEC 62304, ISO 13485, HIPAA or CE-IVDR, or in healthtech.
• Experience with medical imaging, digital pathology or large image and data visualization, including whole-slide image viewers, WebGL or canvas rendering.
• Hands-on CI/CD tooling experience, such as GitLab CI.
• Docker and Kubernetes experience.
• Infrastructure-as-code experience, such as Terraform or CDK.
• Experience integrating ML models or AI-powered features into production applications.

Current Technology Stack

• Python, Vue.js, Django and Django REST Framework.
• Docker.
• AWS: EKS, S3, RDS/PostgreSQL, SQS and MSK/Kafka.
