The weaponization of AI is driving a paradigm shift in the cyber security industry from proactive to preemptive security: clients must now invest more intelligence and effort in understanding their vulnerabilities before their adversaries do (Open AI). The only way to achieve this is to simulate future attack scenarios at scale, and to run them in high fidelity digital replicas of production environments (Gartner/Forrester). SimSpace serves as the AI Proving Grounds to generate hypersynthetic data which pressure tests controls, tools, teams, and agentic capabilities in full kill chain attacks hidden in realistic environmental traffic and patterns of life.

Founded in 2015 by experts from U.S. Cyber Command and MIT Lincoln Laboratory, the platform was initially conceived to assist in Offensive Cyber Operations (OCO), to quickly replicate target environments to conduct mission rehearsal of human operators and their tools to deny (disrupt, degrade, destroy) or deceive (manipulate or exfiltrate data) adversaries. The company has since expanded to serve over a dozen allied governments in OCO/DCO as well as critical infrastructure enterprises around the world. The company is actively investing in the Americas, Asia Pacific, Europe and the Middle East through direct sales and channel partners. SimSpace has launched the AI Proving Grounds Consortium, leading the revolution by creating an open platform for the InfoSec ecosystem to train, validate and operationalize their agentic capabilities before committing to production.

👋 Hi, I'm Ashlyn, Manager of Hiring & Internal Mobility at SimSpace!

At SimSpace, we believe hiring is more than filling roles. It's about building relationships, creating exceptional experiences, and helping people and teams grow thoughtfully.

I'm looking for a Senior Hiring & Internal Mobility Partner to join my team and help us deliver a thoughtful, responsive, and high-quality hiring experience across our global organization.

This role is ideal for someone who genuinely enjoys recruiting, takes pride in delivering a white-glove candidate and hiring manager experience, and knows how to balance quality, speed, and thoughtful execution in an environment where priorities and business needs can evolve quickly.

We're looking for someone with a strong recruiting foundation, sound judgment, and a flexible mindset. Someone who can confidently manage their own searches, build trusted relationships, and adapt when circumstances change without losing sight of the details that matter.

A quick note about this job description: You'll notice it's a little more detailed than most, and that's intentional! I believe hiring should be a two-way conversation, and I want you to have a clear picture of the role, our team, and what success looks like before you decide whether it's the right opportunity for you.

If you enjoy connecting people with opportunities, working across different teams, and finding thoughtful, practical ways to keep things moving, I'd love to meet you!

About the Role

As a Senior Hiring & Internal Mobility Partner, you'll independently manage full lifecycle recruiting across a variety of technical and nontechnical functions, including R&D, Product, Go-to-Market, G&A, and Professional Services.
