Chief of Staff

Deep Fission is a nuclear technology company pioneering the development of a revolutionary deep borehole pressurized water reactor. We recently completed a private placement financing and an Alternative Public Offering and are now operating as a public company while maintaining our startup agility and innovation focus. With strategic partnerships in place, strong private and public investment, and active engagement with the U.S. Nuclear Regulatory Commission (NRC), we are advancing our groundbreaking nuclear technology toward commercial deployment.

The Chief of Staff to the CEO will serve as a strategic integrator within the leadership team. This peer-level position owns two of the company’s most consequential operating systems: the board process and the leadership team’s operating rhythm. The role is designed for a seasoned builder who has run operating systems at high levels and wants the chance to build one from the ground up in a mission‑driven organization.

• Board Process
  • Own board meeting preparation and follow‑through end to end: agendas, materials, pre‑reads, and tracking commitments to close.
  • Serve as the primary point of contact to board members on non‑urgent matters.
• Leadership Team Operating Process
  • Build and run the leadership team’s operating rhythm: standing meetings, decision forums, and communication cadence that keeps the company’s functions integrated.
  • Design and stand up structure where one does not yet fully exist, proactively and without waiting to be asked.
• Organizational Accountability
  • Own the system that tracks commitments across the leadership team so that nothing agreed by the CEO falls through the cracks.
  • Hold decisions steady even when they are reopened in a live conversation, and do so respectfully.
• CEO Preparation & External Engagement
  • Ensure the CEO walks into every significant meeting, investor conversation, and speaking engagement fully briefed and ready.
  • Own strategic initiatives as designated by the CEO.
  • Represent the CEO with board members, investors, and senior partners where appropriate.

• Bachelor’s degree required.
• At least 10 years of senior management experience, including time on a leadership team in a Chief of Staff role.
• Demonstrated experience in strategic planning, organizational design, and cross‑functional program management.
• Demonstrated experience managing real cross‑functional complexity: competing priorities, organizational politics, and holding people accountable without formal authority.
• Has built organizational systems from the ground up, including operating rhythms, decision frameworks, and accountability structures, in a place where none existed before.
• Executive presence and credibility to represent the CEO with board members, investors, and senior partners.
• Comfortable operating in an environment where infrastructure is still being built, rather than needing a lot of structure already in place.
• Public company experience and background in technology, energy, advanced manufacturing, or another regulated industry.
• A genuine passion for Deep Fission’s mission of building faster, safer, and more affordable nuclear power, and a highly self‑motivated approach to work that does not require day‑to‑day direction.

• Advanced degree in business, law, engineering, or a related field.
• Has worked in a founder‑adjacent or early‑stage scaling environment where systems had to be built, not inherited.
• Familiarity with board governance, investor relations, and public company reporting cadences.
• Enough technical or sector credibility to be taken seriously in conversations about nuclear energy, deep technology, or other regulated industries.
• Mission‑Driven and Self‑Directed – Genuinely invested in Deep Fission’s mission and able to generate momentum independently.
• Structural Builder – Builds structure proactively when a gap appears.
• Decision Steadiness – Holds a decision steady even when it gets reopened in a live conversation.
• Direct Communication – Comfortable stepping into direct, sometimes difficult conversations rather than routing around them.
• Judgment & Discretion – Reads a room accurately and…
