Position Summary:

Subtle Medical is seeking a Senior Platform Engineer to join our Platform Engineering team. This role is focused on building, operating, and scaling the backend services and platform systems that power our AI-driven medical imaging products.

You will contribute directly to backend service development and platform systems while helping operate the cloud infrastructure and runtime environment that supports them.

We operate as a high-intensity, AI-native engineering team. AI tools are used to accelerate development, but they are not a substitute for strong engineering fundamentals. This role requires deep experience in enterprise application development, distributed systems, and production environments, with the ability to design, build, and debug reliable systems at scale.

Responsibilities

Job Duties:

• Design, build, and maintain backend services and cloud-native systems across a distributed edgecloud architecture using TypeScript/Node.js and Python.
• Develop and operate on-prem gateway/edge systems that integrate with medical imaging devices via DICOM and coordinate with cloud-based processing pipelines
• Drive system design decisions for distributed, event-driven architectures spanning on-prem and cloud environments, with a focus on scalability, performance, and maintainability of enterprise-grade systems
• Own, operate, and evolve containerized and batch-based cloud workloads (AWS Batch, Docker, GPU-enabled jobs), ensuring reliability and observability in production
• Contribute to and improve deployment automation, including infrastructure as code (OpenTofu/Terragrunt) and CI/CD pipelines (GitHub Actions)
• Contribute to production operations, monitoring, and incident response with an automation-first mindset, including logging, alerting, and system observability
• Debug complex production issues across distributed systems, including asynchronous and batch workflows
• Share ownership of production systems, including leading or supporting incident response and resolution during infrequent, high-impact incidents affecting core cloud and batch workloads
• Work closely with customer success teams to troubleshoot, debug, and resolve production issues
• Collaborate with cross-functional teams to deliver and operate production systems for real-world imaging workflows
• Participate in security, compliance, and quality processes required for healthcare systems

Qualifications

Key Competencies:

• Strong proficiency in TypeScript/Node.js and Python, with experience building and operating enterprise-grade backend applications in production environments
• Experience designing and operating distributed systems, including asynchronous workflows, failure handling, and scalability patterns
• Experience contributing to infrastructure and deployment automation, including infrastructure as code (OpenTofu/Terragrunt) and CI/CD pipelines (GitHub Actions)
• Demonstrated senior-level experience with end-to-end ownership of enterprise-grade production systems
• Strong hands-on experience operating production systems in AWS environments
• 8+ years of professional software development experience, with demonstrated growth into senior-level ownership of production systems
• Experience with both relational and NoSQL databases (e.g., PostgreSQL, DynamoDB)
• Strong production and operational mindset, including monitoring, debugging, incident response, reliability engineering, and security best practices

Education:

• Bachelors degree in Computer Science or equivalent practical experience

Work Experience:

• 8 years+

Nice to Haves:

• Experience working with healthcare data standards (e.g., DICOM, HL7)
• Experience with radiology imaging workflows
• Experience in healthcare or other regulated environments
• Startup or high-ownership team experience
• Hands-on experience building and operating containerized workloads using Docker, including AWS batch or GPU-enabled jobs

Location:

• Remote (USA). Approximately 5% travel required.
