Build APIs, frontend features, and high-quality tested solutions using TypeScript, React, Kotlin, Spring Boot, databases, RESTful APIs, and microservices. Collaborate with UX, Product, and Data Science teams in planning, demos, retrospectives, documentation, mentorship, and knowledge sharing.

Provide hands-on technical leadership for reusable cyber ranges, virtual-machine images, network architectures, and infrastructure automation. Design standards and automation with Ansible and Packer; troubleshoot complex networks, Windows, Linux, VMware, Active Directory, security tooling, and ICS/OT environments. Lead cross-team technical decisions, improve testing and release practices, mentor engineers, delegate ownership, and develop scalable, secure, supportable range solutions.

Leads AI-centric threat hunting initiatives, integrates agentic capabilities into cybersecurity environments, advises customers, and mentors global security teams. Develops threat-hunting methodologies, detection rules, dashboards, and cybersecurity range scenarios. Analyzes telemetry and large datasets using SIEM and EDR tools, supports incident response and digital forensics, facilitates Blue Team exercises, and communicates complex security risks to technical and non-technical audiences. Travel is expected for customer assessments and events.

Operate and improve critical VMware, data center, virtualization, Linux, monitoring, and network infrastructure. Responsibilities include rack-and-stack work, hardware replacement, troubleshooting, incident response, documentation, availability management, basic switch configuration, and on-call support in a high-availability environment.

Lead complex incident response and threat-hunting scenarios from pre-sales through delivery across the Asia Pacific region. Mentor global security teams, facilitate cyber defense exercises, develop instructional content, and help customers integrate and test AI agent capabilities. Analyze enterprise telemetry and threat intelligence, tune security tools, build detection dashboards and parsing rules, and demonstrate EDR and SIEM workflows. The role also involves technical consulting, project ownership, scenario development, team mentorship, and regional client travel of up to 25–30%.

Build the operator-facing web application for an internet simulation platform using React and TypeScript. Create workflows for configuring services, personas, topology, applications, ranges, and platform monitoring. Integrate frontend experiences with control-plane APIs, asynchronous operations, authentication, validation, error handling, and real-time status updates. Contribute to Kotlin and Spring Boot backend services, API contracts, testing, observability, accessibility, security, and performance while collaborating across product, design, infrastructure, network simulation, and SRE teams.

Architects, deploys, and maintains local and cloud-based cyber ranges supporting concurrent training scenarios. Develops Infrastructure as Code automation for environment deployment, reset, and teardown; emulates cloud services; maintains network isolation and security controls; and optimizes resources and costs. Collaborates with content developers, documents architectures and procedures, provides SimSpace expertise, and delivers platform training and knowledge transfer to customers and partners. Requires occasional travel of approximately 10%.

As a Cyber Range Engineer, design and manage computer networks, configure security tools, and troubleshoot IT systems while collaborating with clients and teams.

Technical lead to design and build an eBPF-based kernel-level internet simulation and control plane. Own XDP/TC hooks, BPF maps, topology database, and lightweight in-range agents. Mentor engineers, set architecture, and productionize a proof-of-concept for multi-tenant cyber range network simulation with realistic ASN routing and traceroute fidelity.

Build and operate a catalog of simulated internet services: deploy/automate containerized services on Kubernetes, seed realistic content via scraping/transforms, manage authoritative DNS and email delivery infrastructure, integrate real SaaS/cloud services, instrument observability, and expose service APIs for orchestration while collaborating with identity/persona teams.

Build and own the control plane and orchestration engine for a multi-tenant internet simulation platform: design the platform API, implement the event-driven orchestration backbone, manage persistent storage, create Kubernetes operators/controllers for deployment and upgrades, define authoritative state and recovery behaviors, support in-range proxy agent infrastructure, and partner with SRE on runbooks, observability, and security.
