The role is Staff Engineer — Platform & Enterprise Readiness, owning the Nexus platform that everything else at Cosmon runs on—the desktop application, the enterprise deployment system, and the infrastructure that integrations and agents plug into. This is a pure platform role, building the substrate that makes integrations possible: the desktop app framework, the COM hosting and lifecycle management, the deployment and update machinery, and the enterprise plumbing that gets Nexus installed and running reliably inside Fortune 100 IT environments. The role is directly accountable for four outcomes: speed from download to first successful workflow, resolution speed for client-reported issues, first-attempt deployment reliability across diverse IT environments, and a low production bug count, metrics that determine whether POCs convert into customers. Responsibilities include owning the Nexus desktop app framework and architecture, building COM/native interop infrastructure, designing for process reliability (sandboxing, watchdog supervision, crash isolation) with built-in observability, and creating a plugin/extension architecture for versioned, isolated, and updatable integrations; in Enterprise Deployment & Release Engineering, delivering the deployment package (Defender exclusions, firewall rules, code signing, MSI, Group Policy, SCCM and Intune), owning updates and rollbacks, and partnering with IT security during POCs. The role emphasizes platform observability—logs, traces, and telemetry usable in locked-down environments—while driving onboarding time-to-value, fast issue resolution, and reliable production deployments; it offers early-stage leverage in a small team serving Fortune 100 customers, where platform decisions shape the product and the company.
