Responsibilities
- Set the technical vision and architecture for object, block, and file storage services.
- Design and implement storage control planes, data planes, APIs, and integrations with Radiant services.
- Translate product and customer requirements into robust architectures and technical designs.
- Own storage performance, durability, availability, consistency, and service-level characteristics.
- Profile, benchmark, and tune throughput, latency, and IOPS for AI training, inference, and other data-intensive workloads.
- Integrate storage with compute, Kubernetes, networking, IAM, observability, and developer tooling.
- Design replication, snapshots, data protection, failure recovery, and safe upgrades at scale.
- Drive capacity planning, observability, incident response, and post-incident improvements with SRE.
- Raise engineering standards through mentoring, design reviews, code reviews, and technical leadership.
- Work directly with customers on highly technical storage problems.
Requirements
- Extensive experience building and operating large-scale distributed storage systems or storage-heavy cloud infrastructure.
- Track record of staff- or principal-level technical leadership across multiple teams and complex systems.
- Strong hands-on engineering skills in Go or a similar systems language.
- Deep expertise in object, block, and file storage, snapshots, replication, erasure coding, caching, tiering, and data lifecycle.
- Deep knowledge of storage protocols and interfaces including S3, NFS, SMB, CSI, NVMe/NVMe-oF, RDMA, and POSIX semantics.
- Experience with Kubernetes, containers, high-performance networking, GPU clusters, and cloud platforms.
- Expertise in durability, availability, consistency models, consensus, failure recovery, data integrity, observability, IAM, encryption, and auditability.
- Hands-on experience with WEKA, VAST, DDN, Lustre, Ceph, MinIO, Pure Storage, or similar technologies.
- Understanding of AI and HPC storage patterns, including training data pipelines, checkpointing, and high-throughput parallel file systems.
- Ability to reason about trade-offs among performance, durability, availability, cost, and operational complexity.
- Excellent written and verbal communication skills, including technical design documentation and explaining complex trade-offs.
- Storage-domain expertise extending to how storage architecture affects application and workload performance down to the hardware.
- Ability to influence direction across teams, make long-term architectural decisions, and grow engineers.
- Comfort working directly with customers on highly technical problems.

About Radiant
RadiAnt develops RadiAnt DICOM Viewer, a lightweight Windows application for viewing and analyzing medical images from CT, MRI, PET, ultrasound, and X‑ray. It sells commercial licenses (with a free trial) to radiology practices, hospitals, and researchers, and supports PACS query/retrieve, multi-modality workflows, and 2D/3D reconstructions. The software can open studies from local media and networked DICOM servers for clinical review and teaching use cases.
