Backend Software Engineer (Internet Services Simulation)
About The Position
SimSpace is seeking a Software Engineer to develop and manage the simulated internet services layer of their internet simulation platform. This role focuses on the internet itself, deploying and operating a catalog of simulated and real internet services (e.g., fake GitHub, social media, webmail, AWS, GCP, Azure, and SaaS applications) that red and blue teams interact with. It's a creative and technically diverse position involving service deployment automation, content generation, and DNS and email infrastructure to create a realistic application-layer internet environment. The team is responsible for a persistent catalog of simulated services, integrating real SaaS applications, simulating cloud services, content seeding pipelines, external DNS infrastructure, email delivery, service lifecycle automation, and contributing to the service API layer.
Requirements
- Strong bilingual proficiency in English and Spanish skills required across written, virtual, and in-person interactions.
- Solid experience deploying and operating containerized services in Kubernetes, including writing deployment configuration and automation for a heterogeneous set of applications.
- Hands-on experience with self-hosted open-source platforms (e.g., running own mail server, social media instance, or similar infrastructure).
- Working knowledge of DNS, including operating authoritative nameservers, understanding zone delegation, and configuring records for email authentication.
- Familiarity with email delivery infrastructure: how mail servers work, how sender authentication is constructed, and what makes an email appear legitimate.
- Experience with web scraping, data transformation pipelines, or content generation.
- Comfort working across a broad, heterogeneous service catalog.
Nice To Haves
- 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, 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 correct mail and sender authentication records are generated, and maintain consistency between DNS state and deployed services.
- Build and maintain the email delivery infrastructure that allows the internet simulation platform to send mail into range environments, including correct envelope construction, authentication headers, and support for adversarial email scenarios.
- Collaborate with the identity and persona team to ensure simulated services are correctly provisioned with user accounts and that per-service user state remains consistent.
- Instrument and monitor the simulated service catalog, building observability into service health and range-level activity using the platform's Grafana-based stack.
- Contribute to the service API layer that allows other platform components and external orchestration systems to create and manage simulated services programmatically.
Benefits
- Base monthly pay range: ------ CRC - ----- CRC
- Opportunity for annual bonuses tied to company performance and individual contributions.
- Private medical, dental, vision, and life benefits.
