Senior Software Engineer - Range Operations Team

As a Senior Software Engineer on our Range Operations Team, you will provide deep expertise in microservices, event-driven messaging systems, and containerization to architect the next generation of high-fidelity simulation. You are a technically fearless developer who thrives on solving hard problems in new ways.

In this role, you will go beyond maintaining infrastructure—you will invent it. You will lead the development of bespoke, hybrid solutions that generate realistic simulated traffic across a complex ecosystem—from IoT systems and local software to modern SaaS platforms and cloud-native environments. By leveraging AI, LLM, and advanced API capabilities, you will drive technical innovations that simulate real-life cyber attacks and human-user personas with unprecedented realism and cutting-edge technologies. You will act as a force multiplier for the team, guiding best coding practices and system architecture to ensure our engineering standards remain exemplary.

What will you be doing:

• Bespoke Development & AI Integration: Design and build custom tooling, scripts, and applications that leverage AI and LLMs to generate realistic simulated traffic to SaaS providers, cloud platforms, and enterprise endpoints.

• Core Service Engineering: Design, develop, and maintain core services for cybersecurity range simulation, focusing on scalability, performance, and fault tolerance.

• Technical Leadership & Mentorship: Lead end-to-end technical projects and mentor engineers on the team, promoting a collaborative culture and guiding them in architectural design.

• Infrastructure & Emulation: Create emulated cloud services and synthetic data pipelines, ensuring environments behave realistically under both attacker and defender activity.

• Quality & Observability: Conduct code reviews and implement robust monitoring and alerting strategies to maintain high uptime and adherence to company standards.

• Cross-Functional Collaboration: Partner with Product Managers, UX Designers, and content developers to translate ambitious training requirements into technically sound, user-centered solutions.

• Technical Excellence: Develop and maintain thorough documentation for system design, technical architecture, and troubleshooting guides to ensure knowledge sharing.

What are the qualifications to apply?

To be successful in this role, you need to have:

• Experience: 6+ years of hands-on experience in software development with a strong focus on building large-scale, distributed systems.

• Language Proficiency: Expertise in an OOP-based language such as Java, Kotlin, or Python, with a demonstrable understanding of API design (HTTP/S, REST, OAuth, SAML).

• AI & LLM Capability: Proficiency in leveraging AI, LLM, and API capabilities to solve complex automation and simulation challenges.

• Containerization & Orchestration: Proven experience with unit/integration testing and deploying services in Kubernetes or similar container orchestration platforms.

• Infrastructure as Code (IaC): Proficiency with tools including Terraform, Ansible, and Puppet to manage virtualized platforms (e.g., VMware).

• Specialized Environments: Experience working within or developing for air-gapped environments.

• Networking Knowledge: Expertise in virtual networking architecture, segmentation (VPCs, subnets), and secure connectivity solutions.

Who you are:

• You feel comfortable leading, driving, and delegating team initiatives.

• You enjoy solving complex problems and building solutions through collaborative methods.

• You are focused on the iterative delivery of high-quality, well-tested code and are pragmatic when it comes to trade-offs.

• You have worked in or tangential to the cybersecurity field and understand both offensive and defensive security.

Our Tech Stack:

• Languages: Python, Java, Kotlin, Golang.

• Frameworks/Platforms: Spring Boot, Kubernetes, Docker, VMware.

• Tools: Terraform, Ansible, Git, AI/LLM APIs.
