📋 Description

• Architect and define the overarching infrastructure strategy for SimSpace’s cyber range platform, enabling consistent, secure, and repeatable deployments across SimSpace-hosted data centers, customer-provided hardware, and air-gapped environments.
• Lead the evolution of CI/CD and Kubernetes platforms by designing multi-cluster, multi-environment deployment frameworks using Jsonnet, Grafana Tanka, and Kustomize to improve developer velocity and reduce operational toil.
• Define, measure, and govern Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Error Budgets across the engineering organization, partnering with product and engineering leadership to balance feature delivery with platform stability.
• Architect the enterprise observability strategy using the Grafana stack, designing frameworks for proactive monitoring, complex anomaly detection, and distributed tracing to provide deep visibility into system health, pod scaling, and latency bottlenecks.
• Drive infrastructure security architecture by embedding container hardening, zero-trust network segmentation, and automated compliance policies into deployment pipelines and runtime environments for regulated and customer-managed systems.
• Serve as a strategic technical partner to development teams, advocating for an SRE culture through self-service tooling, paved roads for developers, and standardized operational practices across the engineering organization.
• Act as Incident Commander during high-severity outages, leading blameless post-mortems and implementing systemic, architectural fixes to prevent recurrence of failure classes.
• Mentor senior and mid-level engineers by coaching, documenting best practices, and raising the baseline of engineering excellence through technical leadership and example.
• Design and implement GitOps workflows using GitHub Actions and ArgoCD, applying infrastructure-as-code principles at an enterprise scale to manage complex, distributed systems.
• Build and maintain automation frameworks that support diverse deployment models including on-premises, VMware-based, and pre-packaged hardware-software appliances.
• Collaborate across departments and time zones to ensure platform reliability, security, and scalability for global clients including allied governments, militaries, and enterprises.
• Contribute to the continuous learning culture by participating in internal and external training, cyber conferences, and industry events to stay at the forefront of SRE and DevSecOps practices.
• Influence cross-functional leadership to align engineering teams behind a unified technical vision, negotiating reliability tradeoffs and championing long-term infrastructure investments.
• Ensure compliance with federal employment eligibility requirements and maintain a secure, inclusive, and welcoming environment for all team members.
