Senior Backend Software Engineer, Control Plane & Orchestration

Role Overview

• Design and build the control plane API: the interface that range orchestration and scenario systems use to drive the internet simulation platform, with strong attention to idempotency, consistent error semantics, and the operational patterns that make a platform API pleasant to build on.
• Own the event-driven orchestration layer that coordinates multi-step operations across the platform's subsystems, ensuring that standing up a new range, registering a persona, incorporating a SaaS application, or updating topology propagates correctly and completely across all components.
• Build and maintain the platform's persistent storage layer, providing reliable, well-abstracted storage primitives for the services and subsystems that depend on it, across file, object, and container storage as requirements evolve.
• Own the deployment model for the internet simulation platform itself: the Kubernetes operators or controllers that manage platform lifecycle, the upgrade and rollout strategy for a service that cannot afford downtime, and the configuration model for integrating new ranges.
• Define and own the state model for the platform, what is authoritative where, how components recover from partial failures, and how the platform converges to a correct state after disruption.
• Collaborate with the network simulation tech lead on the in-range proxy agent architecture, owning the infrastructure side of that interface: agent deployment, connectivity management, and the handoff model when an agent loses contact with the control plane.
• Partner with the SRE team on the operational model for a new platform service, establishing runbooks, incident response procedures, and the observability instrumentation that makes the platform debuggable in production.
• Contribute to cross-cutting concerns including configuration management, secrets handling, and the security posture of the control plane.

Requirements

• Strong bilingual proficiency in English and Spanish skills required across written, virtual, and in-person interactions.
• Experience building event-driven or message-driven systems, with an understanding of the tradeoffs involved in different coordination approaches, the implementation will be informed by the architecture, not the other way around.
• Strong Kubernetes expertise including writing operators or controllers, managing custom resources, and reasoning about multi-tenant workload isolation.
• Experience designing and operating storage systems across different storage paradigms, file, object, and block or container storage, and choosing the right abstraction for each use case.
• Experience with air-gapped or on-premises Kubernetes deployments is a strong plus given SimSpace's customer and deployment model.
• Familiarity with infrastructure-as-code and GitOps-based deployment workflows.
