As a Lead IT Systems Engineer at Klaviyo, you will lead the design, implementation, and maintenance of our enterprise SaaS systems. You will spearhead projects that range from SSO/SCIM implementations to complex multi-tool integrations and automations, with a focus on scalability and efficiency. You'll collaborate closely with operations, engineering, and the IT Searchbar team to ensure seamless system performance and act as a technical escalation point for system-related issues.

Key responsibilities include mentoring team members to grow and develop in their careers, establishing team standards, implementing frameworks for project intake and prioritization, and monitoring objectives and key results (OKRs). You will partner with stakeholders to build, maintain, and improve tooling, infrastructure, and documentation that meet current and future business needs. Additionally, you will collaborate with IT and internal teams to automate and improve workflows, implement and enhance escalation processes, and drive IT initiatives.

The ideal candidate will have a minimum of five years' experience in systems engineering within fast-paced and result-driven environments. A proven track record of defining problem statements, managing technical projects, collaborating with stakeholders, and delivering impactful results is essential. Extensive experience in Identity Access Management (IAM), including IdP configuration, management, and maintenance (Okta or Azure experience is preferred), is required. Strong experience working with enterprise-scale networking topics, including routing, DNS, and building and maintaining multiple global office networks and VPNs, is also necessary. Demonstrated proficiency in understanding and integrating Large Language Models (LLMs) or other AI technologies into enterprise systems for automation or process improvement is highly valued.
