📋 Description

• Design, develop, and maintain containerized microservices that emulate offensive cyber attacks and user personas within SimSpace’s cyber range simulation environment, ensuring scalability, performance, and fault tolerance.
• Own end-to-end technical projects from requirements gathering and architecture design through deployment, defining scope, identifying risks, and aligning stakeholders across teams.
• Mentor senior and mid-level engineers by promoting coding best practices, testing methodologies, and architectural design principles to raise the team’s overall engineering bar.
• Define and evangelize technical architecture and system design through documentation, design reviews, and team forums to ensure knowledge sharing and alignment across the organization.
• Collaborate with Product Managers and UX Designers to create user-centered, technically robust solutions that align with business priorities and customer needs.
• Proactively surface technical tradeoffs and their business implications to non-technical stakeholders to inform decision-making.
• Ensure the AUE team’s technical decisions, interfaces, and delivery commitments reflect the needs of the broader organization, measuring success by cross-functional outcomes, not just team output.
• Partner with other engineering teams as both a consumer and provider of APIs and services, treating them as customers with defined SLAs and feedback loops to optimize end-to-end product experience.
• Build and maintain strong working relationships with partner teams by proactively communicating changes, soliciting feedback on interfaces, and ensuring reliability as a high-trust dependency.
• Conduct thorough code reviews to ensure code quality, performance, and adherence to company standards and security requirements.
• Implement robust monitoring, alerting, and observability strategies to maintain high system uptime and enable rapid response to incidents.
• Integrate security and compliance controls into the development lifecycle to ensure services meet regulatory and operational standards.
• Identify gaps in tooling, processes, or architecture before they become critical issues and drive initiatives to address them proactively.
• Operate with high autonomy in ambiguous environments, defining solutions to complex problems and influencing technical direction beyond the immediate team.
• Apply expertise in event-driven messaging systems, microservices, and containerization to deliver core emulation services used by allied governments, militaries, and enterprises worldwide.
• Contribute directly to code, design, and architecture while simultaneously guiding team members and shaping engineering culture.
• Maintain deep understanding of offensive security methods, tactics, and networking concepts including DNS, TCP/IP, and routing protocols to ensure emulation fidelity.
• Embody a Human Centered philosophy by fostering collaboration, continuous learning, and psychological safety within the team and across departments.
• Participate in internal and external learning platforms, cyber conferences, and industry events to support ongoing professional growth.
• Deliver iterative, high-quality, well-tested code with awareness of scalability, reusability, and realistic trade-offs in fast-paced, evolving environments.
• Think in systems, considering how technical decisions impact teams and services beyond the AUE team’s scope.

🎯 Requirements

• 8+ years of hands-on experience in software development with proven skills in building large-scale, distributed systems and operating as a technical lead or Staff-level engineer.
• Expertise in an OOP-based language such as Java or Kotlin, with demonstrable knowledge of API design, integration, and best practices.
• Experience with event-driven architectures and messaging systems (e.g., Kafka, RabbitMQ, or similar).
• Proven experience with unit testing, integration testing, and deploying services in Kubernetes or a similar container orchestration platform.
• Demonstrated ability to design, build, and operate fault-tolerant systems, including requirements gathering, risk identification, and project sequencing.
• Strong communication skills to present and articulate designs to technical and non-technical audiences, including leading architecture reviews and influencing technical direction.
• Understanding of offensive security methods and tactics.
• Knowledge of networking concepts including DNS, TCP/IP, and routing protocols.
