Flam is building AI Infrastructure for Brands in Immersive Advertising spanning across all channels viz. Digital, Broadcast TV, Retail, Communications, Print, OOH etc.Vision: The Immersive & Interactive Layer for Every Screen & SurfaceFlam aims to redefine how consumers interact with ads, content in every shape and form, retail aisles, live broadcasts and fan moments turning content and interfaces into shoppable, shareable experiences that deliver measurable ROI. Flam has raised a $14 million Series A round led by global technology investor RTP Global with participation from Dovetail and select others bringing the total funding to $22 million.The next phase of growth is to accelerate R&D on its app-less Gen AI infrastructure that lets brands create, publish and measure high-fidelity MR, 3 D & Digital experiences inKey Focus Areas:Product Roadmap : Upcoming releases include Gen AI-driven 3 D asset generation, Democratising MR deployment at scale, Enterprise Suite of Products across Industries, and Infrastructure for broadcasters and fan engagement.Geography : Funds will support new enterprise pods in North America, Europe and the Middle East while deepening Asia operations.Partnerships : Flam will expand its partner program for creative studios and global platforms, enabling Fortune 500 brands to move from pilot to rapid global roll-out.What You'll Be Doing:Design and implement custom Kubernetes controllers that manage GPU node lifecycle across multiple cloud providers, handling provisioning, bootstrapping, and de provisioning with zero manual interventionBuild and maintain autoscaling systems that analyze pod resource requirements (GPU count, memory, CPU) and automatically provision appropriate instance types from provider APIsDevelop micro VM-based isolation for multi-tenant GPU workloads using cloud-hypervisor with VFIO GPU passthrough, enabling secure, high-performance compute for inference and training workloadsCreate node bootstrapping automation that provisions bare-metal or cloud instances with container runtimes, GPU drivers, Kubernetes components, and custom networking configurations via cloud-init, Ansible, or TerraformImplement sophisticated networking solutions connecting hybrid infrastructure - GKE/GCE control planes with external GPU workers using Wire Guard, custom CNI configurations, and cross-cloud service meshBuild Kubernetes operators and CRDs for managing ML infrastructure components like model registries, inference endpoints, training job orchestration, and GPU time-slicing configurationsDesign monitoring, cost optimization, and capacity planning systems that provide visibility into GPU utilization, workload patterns, and infrastructure efficiency across heterogeneous compute pools.Work closely with ML researchers to understand workload requirements and translate them into infrastructure automation that enables rapid experimentation and production deployment.What We Need to See :5+ years of experience building production Kubernetes systems with deep expertise in controllers, operators, Custom Resource Definitions, and API machineryStrong proficiency in Go and experience building scalable, reliable services that manage complex distributed systemsHands-on experience with GPU infrastructure in Kubernetes - NVIDIA GPU Operator, device plugins, time-slicing configurations, or custom GPU scheduling logicDeep understanding of Kubernetes architecture including admission controllers, scheduler extenders, resource lifecycle management, and cluster autoscaling mechanismsDemonstrated ability to design and implement automation systems that replace manual processes with API-driven, self-service toolingExperience with at least one cloud provider's APIs (GCP, AWS, Azure) for programmatic compute provisioning and managementStrong Linux systems knowledge including networking (iptables, Wire Guard, CNIs), storage (LVM, device mapper), and virtualization (KVM, QEMU, cloud-hypervisor)Bachelor's/Master's degree in Computer Science, Engineering, or equivalent practical experienceWays to Stand Out from the Crowd :Experience building hybrid/multi-cloud Kubernetes architectures with cross-provider networking and unified control planesDeep familiarity with micro VM technologies (Firecracker, cloud-hypervisor, Kata Containers) and their application to GPU workloadsHands-on experience with VFIO GPU passthrough, SR-IOV, MIG (Multi-Instance GPU), or other GPU virtualization technologiesTrack record of building custom cloud controllers or provider implementations for bare-metal or specialized computeExperience with ML infrastructure patterns - model serving, training orchestration, experiment tracking, or distributed training frameworksContributions to upstream Kubernetes projects, CNCF ecosystem tools, or GPU-related open source projectsUnderstanding of cost optimization strategies for GPU compute, including spot instances, preemption handling, and intelligent workload placementExperience with Infrastructure as Code (Terraform, Pulumi) for complex multi-provider deployments
