Chief of Staff

New York City | Full-time | On-site in SoHo, five days per week

Reports to the CEO and works directly with the founding team

Helios is building a new kind of company to solve America's hardest problems, starting with the government interaction layer.

Government shapes every consequential market, but the infrastructure connecting public institutions and private organizations remains fragmented, manual, and difficult to navigate. Helios is rebuilding that layer.

Our core platform, Proxi, gives organizations the intelligence they need to understand what government is doing, why it matters, and what to do next. From that foundation, we design and deploy secure, mission-specific systems for government agencies, enterprises, and institutions operating in complex and highly regulated environments.

We bring together frontier AI, deep public-sector expertise, and forward-deployed execution. Our team includes leaders and builders from the White House, U.S. Department of State, Datadog, and Microsoft. We are backed by leading institutional investors and trusted by organizations working on high-stakes problems across government and industry.

We are hiring a Chief of Staff to serve as the operating connective tissue across Helios. This person will work directly with the founders and across the company to turn priorities into execution, keep teams aligned, and ensure that important work reaches completion.

This is a hands-on operating role, not a strategy-only position. On any given day, you may move a customer implementation forward, prepare an investor update, run a cross-functional operating review, improve an internal process, conduct market research, help coordinate a hire, or make sure a critical follow-up happens on time. You should be equally comfortable moving between strategic questions and tactical execution.

The right person is highly organized, responsive, resourceful, and calm under pressure. You create clarity in fast-moving environments, communicate with strong judgment, and take personal responsibility for making sure nothing falls through the cracks.
