Arch powers frontline industries with cutting-edge AI.
The US $800 billion frontline-services sector underpins the nation, yet many of these critical businesses still rely on spreadsheets, outdated software, and paper forms. We’re driving energy resilience, economic strength, and long-term prosperity by bringing cutting-edge AI to the frontline services that need it most.

We’re backed by Coatue, Floodgate, Gigascale, ReGen, MCJ Collective, and the founders of Aurora Solar.

Competitive salary + significant equity package based on experience.

We’re hiring a Chief of Staff to the CEO—a future founder or executive operator—who’s ready to work across every part of the company and deliver results on the ground. If you want a front-row seat to company-building and have the stamina to run at founder pace, this is that role.

🎯 Why This Role Exists

This isn’t a support role—it’s a leadership launchpad. You’ll work side-by-side with the CEO and CTO on customer success, operations, go-to-market, talent, investor relations, strategic planning, product insights, and more. Expectations are extremely high.

You’ll toggle between 30,000 ft and ground level execution multiple times a day—drafting our Series A deck in the morning, then solving a customer crisis in the afternoon.

Ideal for someone who thrives in ambiguity, moves fast with precision, and plans to build or run a company within 3–5 years. Expect monthly travel to customer sites and industry conferences.

🛠️ What You’ll Own

Customer Success, Revenue & Marketing
Lead customer calls, deliver customer success that exceeds expectations and drives renewals and expansion, execute quarterly business reviews, and own cross-functional projects that directly impact our Series A path—from new sales motions and website launches to supply chain optimization.
Company Operations
Design and run our operating rhythm: team off-sites, dashboards, vendor negotiations, investor updates, and daily systems that keep everyone aligned and accountable.
High-Stakes Strategic Projects
Co-own make-or-break initiatives such as fundraising strategy, pricing optimization, and market expansion.
Talent & Team Building
Source and close exceptional hires, design onboarding that gets people productive in week one, and build the recruiting playbook that scales our team.

💼 What We’re Looking For

High-Stakes Background: 3–5 years in demanding environments—early-stage startups, top-tier consulting, investing, or founders’ offices—where you led ambiguous projects without guardrails.
Founder Trajectory & Ambition: You see this as a springboard to founding or running a company within 3–5 years. No task too small, no challenge too big.
Revenue & Customer Obsession: You own the full customer journey—from earning trust and closing deals to driving expansion and long-term success.
Extreme Ownership & Execution: You take full accountability, drive outcomes with urgency and precision, and treat every challenge like it’s yours to solve. You don’t need a playbook—you write it.
Analytical & Operational Excellence: Equally at home building financial models, running team off-sites, and writing crisp investor updates. Highly organized under pressure.

🌱 What We Value

Next-level first-principles thinking
Extreme ownership of every task
Bias for action
Low ego, very high standards
