General Manager (Space Energy Solutions)

Moving Space Forward

Rocketdyne is back — and we're just getting started. We are unleashing decades of unrivaled flight heritage to power the most critical missions in space today, from the Nancy Grace Roman Space Telescope to an MMRTG journeying to Saturn's largest moon. National security space is shifting to proliferated constellations, creating compounding demand for exactly what we build. If you want to do the most important work of your career at a company where One, Trust, and Bold are a way of life, Rocketdyne is your place.

The Role

We are seeking a General Manager, Space Energy Solutions to lead one of our most strategically critical and fastest-growing business units. This is a fully remote U.S.-based role spanning four major program areas: Space Power Conversion (Stirling and Closed Brayton Cycle), Power Management and Distribution, Radioisotope Power Systems, and Nuclear Electric Propulsion power and propulsion subsystems.

This is a full P&L leadership role — and a capture-driven one. Architecture and supplier decisions for Nuclear Electric Propulsion at NASA and DoD, Fission Surface Power (Lunar Reactor 1), radioisotope power systems, and Commercial LEO Destination platforms are being made now. The right leader will convert that window into awarded content on a compressed timeline.

Key Responsibilities:

• Own full P&L: revenue growth, profitability, cost control, and margin expansion
• Establish Rocketdyne's position in the Nuclear Electric Propulsion market during the current architecture definition window, shaping requirements with NASA and DoD
• Capture positions on Fission Surface Power (Lunar Reactor 1), Commercial LEO Destination platforms, and radioisotope power systems programs
• Build and maintain executive-level relationships across NASA, DoD, DOE, national laboratories, and commercial space developers
• Assess and mitigate external dependency risk, including reactor developer maturity and nuclear fuel availability
• Drive new business capture and market expansion across government and commercial customers
• Ensure program execution excellence across the portfolio
• Champion innovation and long-range technology investment
• Build a high-performance, accountable team culture
• Lead with integrity, ethics, and a Lean mindset

Why This Role Matters

This is a once-in-a-generation opportunity to shape how humanity powers its most ambitious missions — from the lunar surface to deep space. The decisions being made right now about nuclear electric propulsion, fission surface power, and next-generation radioisotope systems will define the architecture of space exploration for decades. Rocketdyne is already in the room, with proven technology and trusted customer relationships. Now we need a bold leader to close the deals, build the team, and deliver. One, Trust, and Bold — that's how we'll do it.
