Position Overview We are looking for an experienced and forward-thinking Director of IT Infrastructure & Security to lead the design, reliability, security, and cost efficiency of the company’s infrastructure platform across cloud, network, and core systems. This role ensures high availability, scalability, reliability, and operational excellence while enabling rapid product development and secure data operations leveraging AI as a platform. This leader owns the managed environments, cloud-native environments, databases, and DevOps, as well as the company’s security posture and penetration testing program — and will evaluate where AI-assisted tooling can meaningfully improve delivery and operations. You will report to the CTO. This role blends deep technical leadership with organizational influence and hands-on execution. You will be accountable for driving the strategy to build a safe, secure, and scalable infrastructure platform from concept to production, partnering closely with Engineering, and ensuring our solutions meet enterprise-grade standards of reliability, performance, and security. If you’re a self-driven individual with a strong understanding of infrastructure, IaC, DR/BCP, security operations, penetration testing and vulnerability management, SOC 2 compliance, and CI/CD automation and you want to make an impact on technology that reaches dealerships and consumers globally, we want to hear from you.

Requirements

12+ years in infrastructure, cloud, or DevOps engineering, including 3–5+ years in a leadership role
Deep experience with cloud platforms (AWS, Heroku, Linode, or equivalent), Infrastructure as Code (Terraform, Ansible), and modern networking/security architecture
Experience creating and owning an Incident Response Plan and running a penetration testing program, with working knowledge of frameworks like NIST CSF, CIS Controls, OWASP Top 10, and CVSS scoring
Experience with observability/monitoring platforms (SigNoz or equivalent) and proactive alerting
Experience managing production-scale, high-growth SaaS environments
Strong understanding of DR/BCP and compliance frameworks (SOC 2, ISO)
Bachelor’s or Master’s in Computer Science, Engineering, or related field — or equivalent experience

Nice To Haves

Exposure to data platforms (Databricks, analytics pipelines, AWS QuickSight) is a plus
Relevant certifications (preferred, not required): Certified Solutions Architect / DevOps Engineer (AWS, Heroku, Linode), ITIL (service management)

Responsibilities

Own cloud strategy and architecture across our platforms, prioritizing high availability, disaster recovery, and business continuity
Standardize infrastructure patterns across environments and modernize away from legacy dependencies
Own day-to-day cloud and platform operations, including compute, storage, networking, and uptime monitoring
Implement and enforce Infrastructure as Code to make builds repeatable, auditable, and less manual
Own the company's security posture: proactive monitoring, an Incident Response Plan (including a ransomware runbook), and escalation to an MDR/MSSP partner where deeper coverage is needed
Own the penetration testing program end to end — vendor engagements, findings triage, and remediation SLAs
Drive SOC 2 Type II readiness and infrastructure-level security controls (network segmentation, IAM, encryption, secrets management)
Report security posture and open risk to leadership on a defined cadence
Partner with Engineering to improve CI/CD pipelines, reduce deployment friction, and embed security scanning without slowing delivery
Evaluate and integrate AI-assisted tooling into the delivery lifecycle — code generation, test generation, anomaly detection, and security triage — where it measurably improves quality or signal
Monitor and optimize cloud spend, implementing cost controls (rightsizing, reserved instances, autoscaling) and providing regular cost visibility to leadership
Directly manage and develop the DBA, DevOps, and Desktop Support team members, driving accountability and continuous improvement
Own end-user IT support (helpdesk, device lifecycle, endpoint security) delivered through the Desktop Support team member, and stand up security operations primarily through an MDR/MSSP partnership
Evaluate and manage vendors across cloud, security, and monitoring using a Cost / Scale / Quality / Risk framework, ensuring SLAs are met
