About this role.
Bayesian Health is seeking an Infrastructure Engineer to build and operate scalable, fault-tolerant AWS infrastructure supporting a clinical AI and healthcare platform. The role owns infrastructure architecture, Kubernetes/EKS operations, Terraform modules, CI/CD workflows, observability, reliability, and cloud-cost optimization. It also requires close collaboration with security and cross-functional engineering teams to meet HIPAA, HITRUST, FDA, and client requirements for sensitive PHI/PII workloads. This is a senior hands-on startup role with responsibility for improving platform standards while designing an internal AI Ops capability for DevOps optimization.

Sample interview questions
I would begin by defining availability, recovery, performance, and compliance objectives for each workload. I would use multi-AZ managed services where appropriate, autoscaling Kubernetes workloads, infrastructure-as-code, backup and disaster-recovery testing, and clear service-level monitoring. Cost controls would include rightsizing, autoscaling policies, tagging, budget alerts, and regular review of storage, compute, and data-transfer usage.
I use repeatable Terraform modules and versioned configuration to provision clusters, networking, IAM, node groups, add-ons, and baseline policies. For day-2 operations, I focus on upgrade runbooks, capacity planning, workload resource limits, secret management, observability, backup and restore validation, and incident response. I also document operational ownership and automate common maintenance tasks to reduce manual drift.
I would implement protected branches, mandatory peer reviews, automated tests, artifact versioning, and promotion through controlled environments. Each deployment should have auditable links to source changes, approvals, test results, and release records. I would favor automated, reversible deployments with clearly defined rollback procedures and separation between development, staging, and production access.
I would apply least-privilege IAM, encryption in transit and at rest, network segmentation, centralized audit logging, secure secrets management, and continuous vulnerability and configuration monitoring. I would ensure data access is traceable, limit production access through role-based controls, and partner with security stakeholders on threat modeling and compliance evidence. Regular backup validation and incident-response exercises are also essential.
I would first assess user impact and review service-level indicators, recent changes, application logs, infrastructure metrics, traces, and database performance data. I would isolate whether the bottleneck is compute, network, Kubernetes scheduling, connection saturation, slow queries, or an external dependency, then mitigate safely through rollback, scaling, traffic control, or query remediation. After recovery, I would lead a blameless review and implement monitoring, capacity, or architectural improvements to prevent recurrence.
In Brief
We’re a rapidly growing startup on a mission to make healthcare proactive by empowering physicians, nurses, and care team members with real-time data to save lives.
You will build and maintain the infrastructure for the Bayesian platform and develop CI/CD to enable other team members such as software engineers, data scientists, etc. to accelerate their development will drive expansion of our clinical AI/ML module offerings, health system enterprise-wide implementations, and revenue growth.
Who We Are
Bayesian Health’s mission is to improve patient outcomes by empowering clinicians with the insights they need to make the right decision for the right patient at the point-of-care. We’re a diverse team of clinicians, engineers, machine learning experts, product designers, and performance improvement leaders committed to enabling smarter, patient-specific care delivery through unlocking the power of data.
We’re funded by top tier tech and biotech investors: Obvious Ventures, Andreessen Horowitz, American Medical Association’s venture arm, Catalio Partners, and LifeForce Capital. Our company has won many awards; most recent recognitions include: Forbes AI Top 50, World Economic Forum Tech Pioneer, Time Best Inventions, BioTech AI Company of the Year.
What you’ll do
As an Infrastructure Engineer, you will build and maintain the networking and infrastructure for the Bayesian platform and develop CI/CD pipelines to enable other team members such as software engineers, data scientists, etc. to accelerate their development. This role is crucial to drive expansion of our clinical AI/ML module offerings, health system enterprise-wide implementations, and revenue growth.
Responsibilities
