We are looking for a lead Compute Engineer who can help us mature our compute products. We are a small, highly technical team looking to add deep GPU compute experience. ### **The Role** You will work with a small but growing team of engineers, roll up your sleeves on architecture and code, and own both the development as well as the day-to-day health of our compute infrastructure. This is the right role for a senior engineer who is ready to step fully into engineering leadership without losing their technical edge. ### **What You'll Do** - Contribute directly to architecture and code, particularly on GPU provisioning, orchestration, and the customer control plane - Lead a team of engineers across platform infrastructure, backend services, and internal tooling - Own the engineering delivery process: planning, prioritisation, and execution in close collaboration with the founding team - Implement and maintain observability, alerting, and on-call processes to meet customer SLAs - Hire and onboard engineers as the team grows; act as a culture carrier for technical excellence - Work directly with early customers to understand their GPU workload requirements and feed these into the roadmap ### **What We're Looking For** - 7+ years of engineering experience, with at least 1-2 years in a tech lead or engineering manager capacity within the GPU space. - Practical experience with GPU compute - CUDA environments, NVIDIA drivers, MIG/vGPU, or similar - Experience with container orchestration (Kubernetes, Docker) and infrastructure-as-code (Terraform, Ansible) - Deep understanding of GPU cluster management and GPU compute layers (bare-metal provisioning, k8s, inference software, …) - Startup mindset: you move fast, take ownership, and are energised rather than overwhelmed by ambiguity - **Bonus:** - Experience in hyperscalers or Neocloud infrastructure, or data centre deployments - Deep knowledge of job schedulers (Slurm, LSF, Ray), networking (InfiniBand/RoCE), large-scale storage systems (VAST, Weka, DAOS, Ceph, AWS S3, Lustre, GPFS), GPU inference and fine-tuning customer workloads (vLLM, LanceDB …) ### **Why Join** - Rare opportunity to be the technical lead at a company at the centre of the AI infrastructure boom - Hands-on role with real technical depth - this is not a purely managerial position - Attractive equity for an early employee in a high-growth space - Work directly with founders and have a real voice in product and company direction --- *We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
