Role Description
Design, build, and operate a sovereign AI toolchain used in isolated or tightly controlled environments, including model serving, retrieval, orchestration, observability, and secure platform operations for enterprise AI engineering workloads.
This role centers on open-source or open-weight LLM stacks, air-gapped or isolated deployment models, Kubernetes-based platform engineering, GPU-enabled environments, and auditable AI operations suitable for sovereignty-sensitive programs.
Key responsibilities
-
Design and run Kubernetes environments optimized for AI inference, retrieval, experimentation, and agent execution in secure or isolated settings.
-
Deploy and operate open-source or open-weight model stacks, model gateways, vector databases, and supporting platform components.
-
Build reproducible platform automation using Infrastructure as Code and GitOps approaches for stable, auditable delivery.
-
Manage local registries, package mirrors, secrets, access controls, storage, networking, and observability in environments with limited or no public cloud dependency.
-
Optimize GPU, compute, and storage usage for reliable AI workloads while maintaining security and data sovereignty requirements.
Examples of market tools, models, and platform components expected:
-
Inference and local serving stacks such as vLLM, Ollama, llama.cpp, or OpenAI-compatible self-hosted endpoints.
-
Open-source or open-weight models appropriate for sovereign deployment, for example coding-capable and general-purpose families hosted internally through approved serving layers.
-
Platform tooling such as Kubernetes, Helm, Terraform, Ansible, ArgoCD, private registries, Qdrant or similar vector stores, and Open WebUI or comparable internal interfaces.
-
Developer-facing integration options such as VS Code-compatible extensions, Continue-style local model connectors, or editor integrations pointed at internal APIs instead of external SaaS endpoints.
-
Hardware awareness covering GPU-backed nodes, CPU-only fallback options, storage performance, network isolation, and on-prem or dedicated infrastructure patterns.
Qualifications
-
5+ years in platform engineering, DevOps, SRE, or MLOps, with strong Kubernetes and Linux expertise.
-
Proven experience with AI infrastructure, model serving, private or on-prem deployments, and production operations for LLM-based workloads.
-
Strong hands-on skills in Python plus automation tooling such as Terraform, Ansible, Helm, and GitOps workflows.
-
Good understanding of networking, storage, access control, monitoring, and operational hardening in high-security environments.
-
Comfortable working in sovereignty-driven environments where auditability, isolation, and controlled data handling are mandatory.
Additional Information
-
You will be working in the European Union to meet our customers' data security and privacy requirements.
-
Please be informed that our remote working possibility is only available within Hungary due to European taxation regulation.
