Senior Cloud Platform Engineer (DevOps & Integrations)

Toi Labs is hiring a Senior Cloud Platform Engineer to own the AWS infrastructure, backend services, data pipelines, and integrations supporting its TrueLoo health-monitoring product. The role covers system reliability, security, device fleet operations, incident response, and connections to customer and internal systems.

Responsibilities:

• Design, build, and operate our AWS infrastructure and backend services, defined in infrastructure-as-code
• Own CI/CD, observability, alerting, and on-call, and lead incident response when something breaks
• Build and maintain the pipelines that move device images and telemetry from the field into AWS and Snowflake for analysis, ML datasets, and customer-facing alerts
• Build integrations with external systems, such as customer EHR/EMR and care-management platforms and partner APIs, and with our internal tools
• Keep the fleet healthy from the cloud side: device provisioning, software releases through our fleet-management platform, remote diagnostics, and handling devices that drop offline on networks we don't control
• Bring security, access control, and audit discipline to a system that handles health data, and contribute to the documentation supporting our clinical work and FDA pathway

Requirements:

• must be legally authorized to work in the US and reside in the US
• 5+ years of professional experience building and operating production cloud systems (AWS preferred)
• 5+ years writing production Python: services, APIs, and data pipelines, not only scripts
• Strong DevOps fundamentals: CI/CD, infrastructure-as-code, observability, alerting, and real on-call experience
• Experience building and maintaining integrations with third-party systems and APIs, including retries, idempotency, and messy data
• Solid grounding in networking and security practices
• Production experience with PostgreSQL or a comparable OLTP database
• A track record of owning projects end to end without close supervision, and of picking up unfamiliar technology quickly when a project demands it
• Clear written communication, since most of our coordination happens asynchronously
• Genuine interest in health technology, and comfort with the pace and ambiguity of an early-stage company
• This role requires someone who has already operated production systems through a few painful incidents
• We are not able to sponsor employment visas for this role at this time
• Experience as the first or only infrastructure engineer at a startup
• Healthcare interoperability: HL7, FHIR, or EHR integrations
• Regulated environments such as HIPAA, SOC 2, medical devices, FDA design controls, or IEC 62304
• Data warehousing and modeling (Snowflake, dbt)
• Event streaming and queues (Kafka, Kinesis, SQS)
• Managing connected devices in the field: provisioning, OTA updates, remote diagnostics
• Image or video data pipelines
