关于该职位
Pragmatike 正在招聘一名高级 SRE / 基础设施工程师，帮助运营和扩展一个跨裸金属 GPU 节点、Kubernetes、虚拟化、网络和多站点环境的分布式基础设施平台。
你将直接接触基础设施本身，从 BMC、硬件和 MAAS 部署，到 Kubernetes、网络、可观测性、自动化和站点运维。
这是一个需要亲自动手的角色，适合那些喜欢从头到尾负责基础设施、构建可靠系统并自动化一切可以自动化的人员。有初创公司或高速成长经验者优先：自主性、责任感和速度在这里非常重要。
你将负责
- 在基于 Debian/Ubuntu 的裸金属和虚拟化环境中运营和维护大规模 Linux 基础设施。
- 负责基于 MAAS 的裸金属部署，包括区域/机架控制器、PXE、委托、cloud-init、节点生命周期以及 API/CLI 自动化。
- 运营和维护生产环境 Kubernetes 集群，包括升级、节点池、网络、存储、安全加固和故障排查。
- 设计和维护跨 VLAN、L2/L3 路由、绑定接口、VPN、防火墙和 DNS 的多站点网络。
- 使用 Ansible、Bash/Python、OpenTofu/Terraform 和基于 Git 的工作流程来自动化基础设施部署和运维。
- 构建和维护自动化部署流程，包括 PXE、Preseed 和 cloud-init。
- 使用 Prometheus、Grafana、Alertmanager、VictoriaMetrics/VictoriaLogs 或类似工具来运营可观测性平台。
- 定义和改进 SLIs、SLOs、警报和可靠性实践，覆盖基础设施和平台服务。
- 领导基础设施事件响应、故障排查、升级和事后改进。
- 维护跨分布式环境的值班流程和运维覆盖。
- 接触硬件层，包括 IPMI/Redfish、BMC、RAID、存储、硬件诊断和 GPU 基础设施。
- 管理虚拟化平台，包括 Proxmox、KVM/libvirt、OpenStack 或 VMware，必要时支持 GPU 传递。

ABOUT THE OPPORTUNITY
Pragmatike is hiring a Senior SRE / Infrastructure Engineer to help operate and scale a distributed infrastructure platform spanning bare-metal GPU nodes, Kubernetes, virtualization, networking, and multi-site environments.
You’ll work close to the infrastructure itself, from BMCs, hardware and MAAS provisioning through Kubernetes, networking, observability, automation, and site operations.
This is a hands-on role for someone who enjoys owning infrastructure end-to-end, building reliable systems, and automating everything that can be automated. Startup or hyper-growth experience is a strong plus: autonomy, ownership, and speed matter here.
WHAT YOU’LL DO
- Operate and maintain large-scale Linux infrastructure across Debian/Ubuntu-based bare-metal and virtualized environments.
- Own MAAS-based bare-metal provisioning, including region/rack controllers, PXE, commissioning, cloud-init, node lifecycle, and API/CLI automation.
- Operate and maintain production Kubernetes clusters, including upgrades, node pools, networking, storage, security hardening, and troubleshooting.
- Design and maintain multi-site networking across VLANs, L2/L3 routing, bonded interfaces, VPNs, firewalls, and DNS.
- Automate infrastructure provisioning and operations using Ansible, Bash/Python, OpenTofu/Terraform, and Git-based workflows.
- Build and maintain automated deployment workflows including PXE, Preseed, and cloud-init.
- Operate observability platforms using Prometheus, Grafana, Alertmanager, VictoriaMetrics/VictoriaLogs, or comparable tooling.
- Define and improve SLIs, SLOs, alerting, and reliability practices across infrastructure and platform services.
- Lead infrastructure incident response, troubleshooting, escalation, and post-incident improvements.
- Maintain on-call processes and operational coverage across distributed environments.
- Work close to the hardware layer, including IPMI/Redfish, BMCs, RAID, storage, hardware diagnostics, and GPU infrastructure.
- Manage virtualization platforms including Proxmox, KVM/libvirt, OpenStack, or VMware, including GPU passthrough where required.
- Build and maintain internal infrastructure tooling for host discovery, configuration, IPAM, hardware health, and operational automation.
- Own infrastructure lifecycle activities including site onboarding, maintenance, decommissioning, drift detection, and operational runbooks.
- Work closely with engineering and cross-functional teams to improve reliability, resource utilization, and operational efficiency.
WHAT WE’RE LOOKING FOR
- 5+ years of hands-on SRE, Infrastructure, Systems, or Platform Engineering experience.
- Expert-level Linux administration, particularly Debian/Ubuntu.
- Strong production experience with MAAS and bare-metal provisioning.
- Expert-level, hands-on experience operating Kubernetes in production, including cluster lifecycle, networking, storage, upgrades, and troubleshooting.
- Strong network engineering skills across VLANs, L2/L3 routing, bonding, VPNs, firewalls, and DNS.
- Strong automation skills with Ansible, Bash and/or Python.
- Experience with Terraform/OpenTofu and Git-based infrastructure workflows.
- Production experience with Prometheus/Grafana or comparable observability platforms.
- Experience with incident response, on-call operations, monitoring, alerting, and reliability practices.
- Experience with Proxmox, KVM/libvirt, OpenStack, VMware, or comparable virtualization technologies.
- Experience with bare-metal hardware, BMCs, IPMI/Redfish, storage, and hardware troubleshooting.
- Strong understanding of distributed systems, container orchestration, and infrastructure reliability.
- Experience with infrastructure security including RBAC, firewalls, network policies, secrets management, and security hardening.
- Ability to create SOPs, runbooks, and operational processes from scratch.
- Comfortable working autonomously in a fast-paced, engineering-driven environment.
NICE TO HAVE
- Experience operating GPU infrastructure or GPU-heavy Kubernetes/bare-metal environments.
- Proxmox VE with ZFS/Ceph and GPU passthrough.
- VictoriaMetrics / VictoriaLogs or similar large-scale observability platforms.
- NetBox or other IPAM / infrastructure inventory platforms.
- Vault, SOPS, Atlantis, or similar infrastructure security and automation tooling.
- Experience with Cloudflare APIs, DNS automation, or tunnels.
- Experience with UniFi or comparable site networking platforms.
- Experience with service mesh or advanced CNI implementations.
- Go experience, particularly for infrastructure tooling or custom exporters.
- Experience with Ceph or distributed databases running on bare metal.
- Experience operating infrastructure across multiple sites and timezones.
- Experience establishing SRE frameworks and reliability practices in growing organizations.
WHY JOIN US
- 100% remote with flexible working hours
- High-impact role with significant technical ownership and autonomy
- Work directly with bare-metal, Kubernetes, networking, and GPU infrastructure
- International, engineering-driven team
- Strong focus on automation, reliability, and infrastructure at scale
- Opportunity to shape the architecture and operational foundations of a growing cloud platform
