Office Operations Manager, Chicago

Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs. 

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 role is based in our Chicago office and is expected to be in-office 4–5 days per week to support day-to-day operations, employee experience, and on-site execution.

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.

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.

This role will be responsible for:

• 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

• 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

• You’ve helped open, scale, or relocate offices in multiple markets

• You bring a product mindset to operations—you iterate, measure, and improve

• You naturally look for ways to standardize without over-engineering

• You can operate independently in a remote-first company while owning a physical location

• You’re excited by the idea of building something that doesn’t fully exist yet
