Lead Architect

Location: Bangalore, KA, IN

Company: Alstom

Architecture Definition & Governance

Define and maintain the end-to-end software and infrastructure architecture for products based on an HCIplatform (Hyper Converged Infrastructure )

Specify architecture scope, interfaces, responsibilities, and constraints

Ensure architectural consistency across virtualization, deployment, networking, and security domains

Platform & Virtualization Architecture

Architect solutions supporting multiple hypervisors, including XCP-NG (Xen-based virtualization) andKVM-based platforms such as Harvester

Define deployment models for Linux-based operating systems and application images

Guide adaptations of deployment and orchestration tools to support these platforms

Ensure scalability, availability, and maintainability of cluster architectures

Deployment & Tooling

Define architectural requirements for deployment automation and lifecycle management

Contribute to the evolution of deployment centers, pipelines, and tooling supporting cloud based platform usecases

Promote reuse of existing tools, frameworks, and commercial or open-source solutions (COTS) whereappropriate

Administration & Operability

Identify and formalize administration use cases for virtualized environments (e.g., start/stop workloads, lifecycle operations, monitoring)

Define architectural options for common administration across heterogeneous hypervisors Assess the feasibility of orchestration or overlay solutions enabling system-level startup and control

Network & Infrastructure Sizing

• Define network architecture principles, including: o VLAN design o High-bandwidth requirements (e.g., 10G) o Avoidance of unnecessary network complexity
• Ensure alignment with system and infrastructure architecture constraints
• Security & Compliance Ensure architecture compliance with secure boot and platform security principles Collaborate with cybersecurity stakeholders to validate system hardening and trust chains
• Integrate security considerations by design (defense-in-depth, least privilege, lifecycle security)
• Obsolescence & Sustainability Identify and assess technology obsolescence risks (e.g., hypervisor lifecycle evolution)

Competencies & Skills

Strong knowledge of Linux systems and low-level OS concepts

Solid understanding of virtualization fundamentals (VM lifecycle,isolation, networking, storage)

Hands-on experience with Xen, KVM / Harvester, or equivalenthypervisor technologies

Understanding of Kubernetes and container concepts (clusters,workloads, lifecycle)

Ability to design hybrid VM/container architectures

Strong understanding of networking principles (VLANs,segmentation, multiple interfaces, latency considerations)

Awareness of security and isolation mechanisms in virtualizedplatforms, including secure boot concepts

Ability to work in multi-hypervisor environments and understandnested virtualization concepts

Experience with automation, deployment, or platform tooling(CI/CD, Infrastructure as Code, orchestration concepts)
