Chief of Staff to the CEO

Who we are

Arena Physica is on a mission to accelerate hardware innovation that powers human progress. Our name is inspired by Theodore Roosevelt's 'Citizenship in a Republic' speech. To us, entering the Arena means committing fully and accepting the risk of failure in pursuit of an audacious, worthy cause. We believe the future belongs to those brave enough to build it.

Our team of 60 combines AI engineering and applied physics expertise with deep experience in enterprise deployments. We're headquartered in NYC with presences in San Francisco and Los Angeles, backed by ~$90M from Initialized, Founders Fund, Goldcrest Capital, Fifth Down Capital, and Shield Capital.

If you're ready to do the most important work of your career, join us in the Arena.

What we do

At Arena Physica, we're building electromagnetic superintelligence. Our AI platform Atlas operationalizes physics-grounded intelligence to verify, debug, and optimize hardware across its lifecycle. Atlas is already trusted globally by the world's most advanced hardware companies, including AMD, Anduril, and Bausch & Lomb, for applications across R&D, integration testing, production assembly, and field repair.

About the role

As Chief of Staff, you will be an extension of the CEO, and spend most of your time wherever the CEO is prioritizer. Your job is to accelerate the CEO's workflows, driving preparation for every conversation, building the critical material they present and making sure no action item that comes out of a meeting gets dropped.

You'll be on the road alongside the CEO, sitting in on conversations with leaders at the world's most advanced hardware companies You'll dig into customers' problems, track down prioritized action items, and drive special projects.

How you will contribute

• Prep the CEO for every customer and prospect conversation - briefing docs covering who we're meeting, their hardware programs and pain points, what happened last time, what we want out of the meeting, and the questions they're likely to ask
• Be in the room - join customer and prospect meetings alongside the CEO, capture what was said and committed to, and turn it into follow-ups that actually get closed
• Build the materials - customer presentations, pricing models, proposals, and one-pagers, finished to a standard the CEO can put in front of a CTO without a second pass
• Own the follow-through after the meeting - draft the recap, coordinate the inputs needed from engineering and GTM, and stay on the open items until the customer has what they were promised
• Run research and analysis on request - dig into accounts, competitors, markets, and internal numbers, and come back with a clear answer rather than a pile of raw material
• Build deep company fluency - learn our technology, customers, economics, and organization quickly enough to anticipate what the CEO will need before they ask
• Travel domestically and internationally (up to 50% of your time), most of it alongside the CEO
• Work in person at Arena Physica's NYC HQ when not traveling

Qualifications

• 3+ years of professional experience, ideally at a top-tier management consulting firm, paired with time at a high-growth startup - we're looking for the rigor of consulting and the instincts of someone who has operated without a playbook
• Demonstrated interest in hardware - you can point to something concrete: coursework, a technical degree, personal projects, or work with hardware companies. Enough technical curiosity to hold your own in a room full of engineers, and enough humility to learn fast when you can't
• Sound judgment and absolute discretion - you'll be exposed to the company's most sensitive strategic, financial, and personnel information
• An incredibly high bar for quality, with deep intensity and drive – this role will be demanding and require long hours to solve complex problems
• Exceptional craft in the artifacts themselves – you build decks, models, and documents that are clear, rigorous, and visually clean on the first pass, and you can turn one around overnight when the moment calls for it
• Strong written and verbal communication & storytelling – you can move fluidly from investor-ready financial models to polished customer presentations to a crisp internal memo, communicating clearly and concisely to a wide variety of stakeholders
• A track record of creative problem solving and owning impact at scale - you have a reputation for making magic happen
• Comfort operating without ego - no task is beneath you, and you're willing to chase senior people for answers until you get them
• A deep scrappiness and intrinsic desire to win despite the odds
