Senior Systems Architect

<p style="line-height: 1.5;"><strong><span style="font-size: 12pt;">About SimplePart</span></strong></p> <p style="line-height: 1.5;">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. &nbsp;</p> <p style="line-height: 1.5;"><strong><span style="font-size: 12pt;">The Opportunity</span></strong></p> <p>The SimplePart product is entering an exciting modernization phase. As the Sr. Solutions Architect, you will design and build SimplePart’s AWS platform from the ground up, defining the target-state architecture, establishing infrastructure-as-code foundations, and leading the migration of workloads from four colocation datacenters into a modern, scalable, and compliant cloud environment.&nbsp;</p> <p>You’ll own the architectural vision end-to-end: compute, networking, data, security, and observability. You’ll work closely with development, product, and executive leadership to ensure the cloud platform supports a modernized application stack while meeting compliance requirements.&nbsp;</p> <p>Beyond the build, you’ll serve as a technical leader, mentoring engineers, setting cloud engineering standards, and helping shape the direction of SimplePart’s infrastructure organization through a multi-year transformation. There will be some necessary work to support networking upgrades on the current platform to maintain stability during the migration timeframe. &nbsp;</p> <p style="line-height: 1.5;"><strong><span style="font-size: 12pt;">Key Responsibilities</span></strong></p> <p><strong>Cloud Architecture &amp;
