About The Position

Cohesity is a leader in AI-powered data security and management. Aided by an extensive ecosystem of partners, Cohesity makes it easy to secure, protect, manage, and get value from data — across the data center, edge, and cloud. Cohesity helps organizations defend against cybersecurity threats with comprehensive data security and management capabilities, including immutable backup snapshots, AI-based threat detection, monitoring for malicious behavior, and rapid recovery at scale. We’ve been named a Leader by multiple analyst firms and have been globally recognized for Innovation, Product Strength, and Simplicity in Design. Join us on our mission to shape the future of our industry. About the Role We are looking for an IT Architect to join our Core Platform & Lab Services organization based in our Heathrow, FL office. This is a senior individual contributor role on the CPLS team with primary ownership of AWS cloud architecture and broad responsibility across Cohesity's hybrid infrastructure -- including the physical lab environment that directly enables Cohesity's product engineering and QA teams. As an IT Architect, you will be the design authority for cloud and infrastructure initiatives, translating business requirements and IT strategy into scalable, secure, and operationally sustainable architectures. You will define standards, produce reference architectures, and work closely with engineering, operations, security, and IT leadership to ensure what gets built is what should be built. This is not an implementation role. You will operate ahead of delivery: designing, deciding, governing, and enabling the engineers who build and operate the systems you architect. You will own Architecture Decision Records, participate in architecture governance, and be a sought-out voice for design input across the team.

Requirements

8+ years of experience in IT infrastructure or cloud architecture roles, with at least 4 years focused on AWS.
Deep, hands-on AWS expertise: VPC, EC2, S3, RDS, EKS, Lambda, IAM, Organizations, Control Tower, Transit Gateway, Direct Connect, and related services.
Demonstrated experience designing and governing multi-account AWS environments at enterprise scale.
Strong proficiency in infrastructure-as-code, specifically Terraform; experience with Ansible or equivalent.
Experience architecting large-scale virtualization environments; familiarity with VM lifecycle management, resource scheduling, and multi-tenant isolation at scale.
Experience architecting hybrid cloud environments connecting on-premises infrastructure to AWS.
Proficiency in cloud cost management: tagging strategies, cost allocation, Reserved Instance planning, and FinOps frameworks.
Experience with identity and access management architecture including Entra ID, SSO/SAML/OIDC, RBAC, and zero-trust network access.
Strong understanding of network architecture: routing, DNS, firewalls, load balancing, and hybrid connectivity patterns.
Experience producing architecture documentation including high-level designs, reference architectures, and ADRs.
Demonstrated ability to influence technical direction across teams without direct authority.
Strong communication skills: able to translate complex architectural decisions for both engineering and executive audiences.

Responsibilities

Own the architecture of Cohesity's AWS environment, including landing zone design, account structure, network topology, IAM, and cost governance.
Define and maintain cloud architecture standards and guardrails across compute, storage, networking, containers, and serverless services.
Architect multi-account AWS environments using AWS Organizations, Control Tower, and Service Control Policies.
Design and govern cloud-native and hybrid connectivity patterns including Direct Connect, Transit Gateway, VPC peering, and PrivateLink.
Lead FinOps architecture: define tagging standards, cost allocation models, Reserved Instance and Savings Plan strategies, and cloud cost governance frameworks.
Drive infrastructure-as-code adoption using Terraform and Ansible across the AWS environment; define IaC standards and module patterns for engineering teams.
Evaluate and recommend AWS services and architectural patterns; produce documented trade-off analyses with clear recommendations.
Own the architecture of Cohesity's three physical engineering lab facilities, which collectively support 50,000+ VMs and 10,000+ hardware devices serving Cohesity product engineering and QA teams.
Design virtualization, compute, storage, and networking architecture for lab environments at scale, including resource pooling, tenant isolation, and capacity management across concurrent product workloads.
Architect hardware lifecycle and bare-metal provisioning workflows; define automation frameworks for VM provisioning, environment management, and self-service infrastructure consumption.
Define observability and resiliency architecture for lab environments; ensure lab availability and performance meet the needs of internal product engineering teams.
Architect hybrid infrastructure solutions spanning on-premises data centers, AWS, and other hyperscalers.
Define integration patterns and connectivity standards between on-premises environments and cloud, including identity federation and network segmentation.
Design compute, storage, and networking architectures for enterprise workloads across hybrid environments.
Architect disaster recovery and resiliency patterns; define RTO/RPO requirements and validate through design.
Maintain service dependency models in CMDB to support impact analysis and incident response.
Own the infrastructure architecture for Cohesity's internal AI foundry platform: GPU and accelerator compute environments, multi-tenant model serving infrastructure, and AI data pipeline architecture.
Design AI agent orchestration infrastructure: tool-use patterns, multi-agent system topology, and MCP/API integration patterns that are safe and governable at enterprise scale.
Architect the AI API gateway layer: model routing, rate limiting, cost allocation, audit logging, and controls that prevent ungoverned shadow AI consumption across the organization.
Define the observability architecture for AI workloads as a distinct layer from traditional infrastructure monitoring -- covering model drift detection, hallucination and quality monitoring, and prompt/response logging for compliance and evaluation pipelines.
Architect AI-specific security controls: IAM and zero-trust patterns extended to AI workloads, LLM-specific attack surface coverage including prompt injection, data exfiltration via model output, and supply chain risks in model and tool dependencies.
Partner with enterprise technology team on application and model layer architecture; ensure the infrastructure layer is designed to support their roadmap without creating platform constraints.
Contribute to CMDB governance and CI lifecycle architecture; define and maintain service dependency and data model standards.
Architect Kubernetes-based platform services; define container orchestration standards, Helm patterns, and GitOps workflows.
Design integration patterns between enterprise SaaS platforms, internal systems, and AWS-hosted services.
Define API governance standards, event-driven integration patterns, and data flow architecture.
Ensure data architecture aligns with IT governance, CMDB, and asset management requirements.
Co-own the CPLS technology roadmap with IT leadership; translate architectural direction into prioritized initiatives with clear business rationale.

Define and maintain reference architectures and architecture standards for assigned domains.
Participate in architecture review and provide design approval for initiatives within the domain.
Reduce architectural fragmentation by championing reusable, documented patterns over bespoke one-off implementations.
Produce curated, opinionated technology guidance for the CPLS team: translate emerging technology into clear assessments of what it means for our existing architecture and what we should do about it.
