Jobs at SimSpace

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%.

Lead cybersecurity technical sales cycles across the Americas, including discovery, solution design, evaluations, pilots, demonstrations, RFI/RFP responses, and technical close support. Build custom integrations using scripting, APIs, and protocols; connect customer security tooling to cyber ranges; and support AI-agent security evaluations. Partner with sales, product, customer success, professional services, resellers, and integrators while serving as a technical advisor and regional thought leader.

Lead complex threat hunting and incident response scenarios from pre-sales through delivery and execution. Mentor global security teams, develop cyber threat scenarios, facilitate defense exercises, and provide technical consulting on AI agents and cybersecurity safeguards. Analyze large-scale host, network, and application telemetry; tune SIEM and EDR tools; establish detection rules and dashboards; assess customer capabilities; and communicate technical risks to varied audiences. The role is based in Singapore with regular regional client travel.

Build, test, and maintain full-stack product features across frontend, backend, API, and data layers. Own well-scoped features end-to-end, collaborate with product/UX/QA/data teams, improve reliability and observability, participate in planning and code reviews, and write maintainable, well-tested production code.

Lead and mentor threat hunting and blue team activities across enterprise clients; design and run cyber range exercises and CTFs; build detection rules, dashboards, and toolsets; analyze large telemetry datasets; integrate and test AI/agentic capabilities; advise on security stack setup and incident response; travel to customer sites (up to ~20%).

Manage technical delivery of cyber range engagements: coordinate environments, lead exercise planning and execution, support AI agent training/validation, liaise between customers and Professional Services, document outcomes, and maintain customer relationships. Travel up to 25%.

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.

Lead and grow a full-stack application engineering team delivering end-to-end product features (React frontend, Kotlin-backed services). Own hiring, coaching, delivery, architecture, technical debt, quality, and cross-team execution. Drive product-aligned priorities, unblock hard problems, improve processes, and ensure operational ownership and predictable delivery.

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.

Develop and maintain full‑stack features across frontend and backend, collaborate with UX/Product/Data Science, participate in planning/demos/retrospectives, write tests and documentation, mentor peers, and deliver iterative high‑quality code for a microservices-based platform.

Design, develop, and maintain containerized microservices for cyber range simulation; lead technical projects, mentor engineers, ensure security/compliance, implement monitoring, conduct code reviews, and document architecture and best practices.

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.
