Technical Lead - GPU Infrastructure

As Technical Lead for Cosmic AC at Tether Data, you own the architecture and delivery of a GPU compute and managed inference platform expanding from orchestrated workloads on a managed cluster to the full stack on bare-metal GPU infrastructure. You lead a distributed engineering team of about twelve engineers across backend, frontend, DevOps, QA and documentation, reporting to the Senior Technical Product Manager while owning architecture, implementation, delivery plans and the technical interface to infrastructure partners. This is a hands-on infrastructure leadership role with a fixed delivery window in its first six months.

What you'll do

• Own the platform architecture end to end, driving architecture proposals, high-level and low-level designs through review and keeping them current as the baseline
• Lead and line-manage a distributed team across backend (Node.js), frontend (React), DevOps, QA and documentation, setting engineering standards, conducting code and design review, managing release gates, running one-to-ones, and providing growth and performance input
• Design, build and operate a managed Slurm service for research users, including controller and accounting, partitions and login nodes, node onboarding and acceptance, driver and CUDA baseline and upgrades, stalled-job and node-health detection, drain and autohealing, and storage visibility, identity and isolation
• Own cluster bootstrap and lifecycle on partner-provided bare metal, including NVIDIA GPU Operator and Network Operator, VM-based GPU isolation (KubeVirt and VFIO), and day-2 operations such as upgrades, backup and recovery, and node replacement
• Design serving architecture for managed inference at scale, including multi-GPU and multi-node parallelism, autoscaling, request routing and endpoint reliability, and confidential-compute-capable capacity for sensitive workloads
• Build observability and operations across control plane, GPU fleet and application tiers, including metrics, logging, alerting and SLOs, incident response and post-incident review, and an on-call model a small team can sustain
• Serve as the primary technical interface to infrastructure partners and vendors, turning requirements into written specifications and acceptance tests, running escalations to closure, and providing technical input to capacity planning and hardware sourcing
• Work directly with research, model-training and product teams to translate their workloads into platform requirements and broker capacity when it is short
• Complete the platform team and set the technical bar for engineers who join it

What you bring

• Hands-on experience designing and operating GPU infrastructure at scale
• Strong knowledge of Kubernetes, including cluster lifecycle, networking and GPU enablement
• Experience with Slurm or similar HPC job schedulers
• Proven ability to lead and line-manage distributed engineering teams
• Excellent English communication skills
