Job summary

SimSpace, a leader in AI-driven cyber range solutions, is seeking a Backend Software Engineer, Internet Services Simulation. You will design and operate the Kubernetes-based deployment automation for the simulated service catalog, and build content seeding pipelines that make fake services feel authentic.

Qualifications

• Strong bilingual proficiency in English and Spanish across written, virtual, and in-person interactions.
• Solid experience deploying and operating containerized services in Kubernetes.
• Hands-on experience with self-hosted open-source platforms — you have run your own mail server, stood up a social media instance, or operated similar infrastructure.
• Working knowledge of DNS — operating authoritative nameservers, zone delegation, and email authentication records.
• Familiarity with email delivery infrastructure: how mail servers work, sender authentication, and deliverability.
• Experience with web scraping, data transformation pipelines, or content generation.
• Comfort working across a broad catalog of services and technologies.
• Familiarity with PKI and TLS fundamentals is a plus.
• Experience in cybersecurity, red team infrastructure, or cyber range environments is a plus.

Responsibilities

• Design and operate the Kubernetes-based deployment automation for the simulated service catalog, including deployment configuration for each service type, health monitoring, and lifecycle management.
• Build and maintain content seeding pipelines that scrape, transform, and inject realistic content into simulated services.
• Own the external DNS layer: configure and operate authoritative DNS for all simulated domains, ensure mail and sender authentication records are generated at provisioning time.
• Build and maintain the email delivery infrastructure enabling realistic and scenario-driven email in range environments.
• Collaborate with the identity and persona team to provision user accounts and maintain per-service state consistency.
• Instrument and monitor the simulated service catalog with Grafana-based observability.
• Contribute to the service API layer to enable programmatic creation and management of simulated services.
