Infrastructure & Platform Architect

You work closely with the CTO, DevOps engineers and tech leads in a technically rich environment combining health data, HPC, distributed services and data pipelines., Design the infrastructure platform. Define pragmatic architectures for compute, networking, storage, containers and shared platform services.

Standardize infrastructure. Define reusable patterns and technical standards that can be implemented and automated by the DevOps team.

Design for operations. Ensure architectures are observable, maintainable, scalable and recoverable, keeping HPC compatibility in mind.

Integrate security by design. Cover network segmentation, IAM, secrets, TLS, encryption and least-privilege principles.

Plan for failure and growth. Define high availability, backup, disaster recovery, capacity and lifecycle strategies.

Stay hands-on. Review configurations, prototype solutions and help investigate complex infrastructure issues.

FinOps. Control costs on the platform and optimize spendings.

Document decisions. Maintain architecture diagrams, standards and technical decision records.
