Backend Software Engineer (Internet Services Simulation)

SimSpace Corporation

13d • Remote

About The Position

SimSpace is seeking a Software Engineer to build and operate the simulated internet services layer of its internet simulation platform. This role focuses on the internet itself, deploying and operating a persistent catalog of simulated and real internet services (e.g., fake GitHub, fake social media, fake webmail, AWS, GCP, Azure, and dozens of real SaaS apps) that red and blue teams interact with. This is a creative and technically broad role that combines service deployment automation, content generation, and DNS and email infrastructure to produce an internet environment that is indistinguishable from the real thing at the application 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 — you have run your own mail server, stood up a social media instance, or operated similar infrastructure and understand the configuration complexity involved.
• Working knowledge of DNS — not just querying it, but 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 to receiving infrastructure.
• Experience with web scraping, data transformation pipelines, or content generation.
• Comfort working across a broad, heterogeneous service catalog — this role rewards generalist depth across many technologies over deep specialization in one.

Nice To Haves

• Familiarity with PKI and TLS fundamentals is a plus — understanding how certificate trust chains work and how clients are configured to trust custom certificate authorities.
• 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 correct mail and sender authentication records are generated at domain provisioning time, 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 at persona registration time and that per-service user state remains consistent with the broader persona definition.
• 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: 1,250,000 CRC - 2,250,000 CRC
• Opportunity for annual bonuses tied to company performance and individual contributions.
• Private medical, dental, vision, and life benefits.
• Access to company-paid counseling, coaching, and resources for you and your family through Spring Health.
• Paid leave plans for parental leave.
• Equity stock options at hire, with annual performance-based grants.
• Access a LinkedIn Learning membership.
• Monthly reimbursements for meaningful connections with teammates through our SocialSpace Community.
