Infrastructure & Network Architect
First seen by Alion on Aug 17, 2026.
Role Overview :
We are seeking an experienced Infrastructure & Network Architect to lead the design, sizing, and deployment of scalable infrastructure and networking solutions across our AI-driven platforms, data ecosystems, and digital products.
This role is critical in enabling high-performance, secure, and scalable deployments across on-premises, hybrid, and cloud environments, particularly for mission-critical domains such as airport operations and real-time analytics platforms.
Key Responsibilities :
1. Infrastructure Architecture & Sizing :
- Design and size infrastructure for products, platforms, PoCs, and enterprise deployments.
- Define compute, storage, GPU, and networking requirements for AI/ML workloads, real-time data platforms, and analytics systems.
- Create standardized sizing models for small, medium, and large deployments.
2. Network Architecture & Integration :
- Design and implement network architectures aligned with customer environments including on-prem DCs, private cloud, AWS, and Azure.
- Define VPCs, subnets, routing, NAT, firewalls, VPNs, load balancing, and secure connectivity patterns.
- Ensure low-latency, high-throughput connectivity for real-time operations.
3. Solution Deployment Architecture :
- Architect end-to-end infrastructure for internal platforms, third-party products, and edge systems.
- Evaluate customer infrastructure readiness and recommend optimizations.
- Support deployment strategies for on-prem, hybrid, cloud-native, and air-gapped environments.
4. Performance, Scalability & Reliability :
- Ensure infrastructure supports high availability, failover, DR strategies, and horizontal/vertical scalability.
- Define benchmarking and capacity planning models.
5. Security & Compliance :
- Design secure infrastructure aligned with enterprise standards (IAM, network isolation, encryption) and compliance (ISO 27001).
- Implement zero-trust principles, secure API flows, and network segmentation.
6. Cross-Functional Leadership :
- Lead infrastructure and network discussions across product design, architecture reviews, and production rollouts.
- Collaborate with Product, Engineering, DevOps, Data Engineering, and Customer IT teams.
7. Standards, Documentation & Governance :
- Create architecture blueprints, deployment reference architectures, and infrastructure sizing guides.
- Contribute to Architecture Review Board (ARB) and governance processes.
Required Skills & Experience :
Core Infrastructure :
- Strong experience in data center and enterprise infrastructure design, virtualization, containerization (Kubernetes), and storage systems.
Networking :
- Deep understanding of TCP/IP, DNS, routing, firewalls, VPNs, cloud networking (AWS/Azure), and load balancing.
Cloud & Hybrid :
- Hands-on experience with AWS, Azure, GCP, and hybrid/air-gapped environments.
AI/ML & Data Platforms :
- Experience supporting infra for GPU workloads (H100, L4), data platforms (Kafka, Spark, Flink), and real-time analytics.
Deployment & DevOps :
- Familiarity with CI/CD pipelines, Infrastructure as Code (Terraform), and observability.
Ideal Candidate Profile :
- 10+ years of experience in infrastructure and network architecture.
- Proven experience in designing and deploying large-scale, mission-critical systems.
- Strong ability to translate product requirements into scalable infrastructure designs.
- Experience working in customer-facing roles and complex enterprise environments.
