Building the Future of Crypto. Our Krakenites are a world-class team with crypto conviction, united by our desire to discover and unlock the potential of crypto and blockchain technology.

The opportunity:

  • Own and operate GPU and accelerator clusters used for training, inference, evaluation, and experimentation, including drivers, runtimes, kernels, device plugins, node configuration, scheduling primitives, and workload isolation.
  • Design infrastructure that enables Kraken teams to run models locally on GPUs where it is strategically and economically preferable, reducing unnecessary dependency on external providers and containing compute costs.
  • Build and improve scheduling, orchestration, placement, quota management, and utilization systems across heterogeneous accelerator environments.
  • Optimize inference pipelines for latency, throughput, reliability, memory efficiency, and cost using frameworks such as vLLM, Triton Inference Server, TensorRT, or equivalent serving stacks.
  • Partner with ML engineers and researchers to remove bottlenecks in training, evaluation, batch inference, online inference, deployment, and production debugging workflows.
  • Build observability for GPU utilization, memory pressure, queue depth, saturation, token throughput, request latency, failed workloads, capacity pressure, and spend.
  • Drive reliability, incident response, alerting, runbooks, and post-incident improvements for always-on AI compute infrastructure.
  • Evaluate and integrate new hardware, cloud instance families, specialized accelerators, runtimes, schedulers, and serving frameworks as the AI infrastructure landscape evolves.
  • Build tooling that makes GPU usage visible, accountable, and easier for internal teams to consume without needing to become infrastructure experts.
  • Contribute to long‑term architecture decisions that balance performance, cost efficiency, scalability, operational simplicity, and production safety.

Skills you should HODL:

  • 5+ years of infrastructure engineering experience, with significant time spent on GPU compute, ML infrastructure, distributed systems, high‑performance computing, or large‑scale production platforms.
  • Hands‑on experience operating GPU clusters or accelerator‑backed infrastructure in production or production‑like environments, including scheduling, orchestration, utilization monitoring, and cost optimization.
  • Strong systems engineering fundamentals across Linux, networking, storage, containers, Kubernetes, distributed runtimes, and production debugging.
  • Experience with ML serving frameworks such as vLLM, Triton Inference Server, TensorRT, TorchServe, KServe, Ray Serve, or equivalent systems.
  • Proficiency in Python for infrastructure automation, tooling, debugging, integration, and operational workflows.
  • Practical understanding of performance tradeoffs across batching, concurrency, memory usage, GPU utilization, model size, latency, throughput, availability, and cost.
  • Track record of optimizing compute costs while maintaining clear performance, reliability, and availability expectations.
  • Experience building observable systems with useful metrics, logs, traces, dashboards, alerts, and incident workflows.
  • Comfortable working in high‑stakes, always‑on environments where uptime, throughput, correctness, and operational discipline are critical.
  • Clear communicator who can translate infrastructure tradeoffs for researchers, product teams, platform engineers, security stakeholders, and engineering leadership.

Nice to haves:

  • Experience at a frontier AI lab, hyperscaler, high‑frequency trading firm, research platform, or high‑scale ML organization.
  • Familiarity with custom silicon or specialized accelerators such as TPUs, AWS Trainium, Gaudi, or similar platforms.
  • Background in capacity planning, procurement input, reserved capacity strategy, cloud accelerator economics, or GPU fleet cost management.
  • Experience with distributed training frameworks such as DeepSpeed, Megatron‑LM, FSDP, Ray, or equivalent systems.
  • Experience debugging CUDA, NCCL, kernel, driver, runtime, memory, networking, or low‑level performance issues.
  • Experience with Rust, C++, Go, CUDA, or other systems languages used for performance‑critical infrastructure.
  • Crypto, financial services, trading infrastructure, or security‑sensitive production infrastructure experience.
