Role
Who you are
- If you’re someone who sees an office not just as a space but as a system that enables people to do their best work, this role is for you
- Proven experience in office operations, workplace management, or facilities at a scaling company
- Experience managing physical spaces AND projects (not just one or the other)
- Strong project management skills with the ability to drive multiple initiatives simultaneously
- Experience with vendor management, budgeting, and lease or contract negotiation support
- Ability to translate ambiguous business needs into structured plans and execution paths
- Strong cross-functional partnership skills; comfortable influencing without formal authority
- High ownership mindset—you see problems and solve them without waiting
- You are equally comfortable in the details and the strategy
- You think in systems, not one-off solutions
- You prioritize speed + quality, not perfection
- You are pragmatic—you know when “good enough” is the right call
- You take pride in making environments feel effortless for others
What the job involves
- We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners
- We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants
- Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results
- We’re looking for an Office Operations Manager who can both run a high-functioning local office (Chicago) and help design and scale our broader workplace strategy across the U.S
- This is not a facilities-only role. This is a operator + strategist role for someone who is equally comfortable:
- Restocking a fridge and running a great in-office experience
- Supporting lease negotiations and standing up new locations
- Translating ambiguous business needs into scalable workplace solutions
- As Horizon3 continues to grow, we need to move from ad hoc office decisions to a thoughtful, repeatable, and scalable workplace model. This role is a key part of building that muscle
- Help stand up and operationalize our new Chicago office, bringing a thoughtfully designed space to life and ensuring it runs smoothly from day one
- Own the day-to-day operations of the Chicago hub, ensuring a high-quality, seamless employee experience
- Manage vendors, supplies, office services, and on-site logistics
- Support in-office events, team gatherings, and leadership visits
- Act as the local point of contact for employees, leaders, and cross-functional partners
- Maintain a workplace that reflects our culture: high ownership, low friction, high trust
- Partner with Sr. Director, People Operations, Finance, and the broader leadership team to define our U.S. workplace strategy
- Evaluate new market opportunities (e.g., NYC, D.C.) based on business needs, hiring plans, and cost considerations
- Translate ambiguous requirements into clear scopes, options, and recommendations
- Lead end-to-end office expansion projects, including:
- Market research and location evaluation
- Scoping trips and on-the-ground assessments
- Requirements gathering from business stakeholders
- Own timelines, dependencies, and execution from idea → decision → launch
- Build repeatable frameworks for:
- Office evaluation and decision-making
- Vendor management and cost optimization
- Workplace standards across locations
- Identify opportunities to reduce friction, improve consistency, and scale efficiently
- Partner cross-functionally (People, Finance, IT, Security) to ensure alignment and execution
