Senior Systems Architect
Infomedia Americas (SimplePart) | Atlanta, GA On-site (2-3 days/week) | Full-Time
About SimplePart
SimplePart, part of Infomedia’s global automotive SaaS platform, operates approximately 2,750 dealer websites across 25+ OEM catalogs. Our parts e-commerce solutions serve dealership networks globally, processing transactions across multiple payment integrations in a PCI DSS-regulated environment. We are entering a pivotal modernization phase while maintaining rigorous compliance with PCI DSS 4.0 and ISO 27001 and pursuing SOC 2 certification.
The Opportunity
As Senior Systems Architect, you will own the architectural vision for SimplePart’s infrastructure end-to-end through maintaining the reliability and security of our current global colocation environment while designing and building the AWS platform that will replace it. This role is both hands-on and planning. You will need to help maintain our current stack and stand up the target-state cloud environment.
You’ll work across four colocation datacenters (Atlanta, Amsterdam, London, Portland), owning network design and operations, security posture, and compliance readiness, while architecting and executing the migration of workloads into a modern, scalable, and compliant AWS environment.
Beyond the technical work, you’ll serve as a technical leader through technical mentoring, setting standards, and shaping the direction of the infrastructure and security organization through a multi-year transformation.
Key Responsibilities
Network Architecture & Operations
- Own the design, implementation, and ongoing optimization of network architecture across all colocation sites and cloud environments.
- Architect and manage network segmentation, VLANs, VPN tunnels, routing, DNS, and DHCP across a geographically distributed infrastructure.
- Administer and optimize pfSense firewalls and Snort IDS/IPS, ensuring network integrity and compliance with segmentation requirements.
- Cloudflare WAF and proxy configurations to protect public-facing dealer websites and e-commerce applications.
- Design hybrid connectivity solutions bridging on-premises datacenters and AWS as workloads migrate.
Infrastructure & Systems Architecture
- Maintain and optimize Windows Server environments (2016–2022) across production, staging, and development tiers.
- Manage Active Directory, IIS, Group Policy, and supporting services for dealer websites.
- Manage Proxmox virtualization environments, optimizing resource allocation and infrastructure flexibility.
