Product Manager – Propulsion Test

Hermeus is a venture capital-backed aerospace and defense technology company focused on building high-speed products that sustainably deliver asymmetric advantage to the Department of Defense and allied partners. Using an iterative development approach to aircraft, Hermeus’ high-Mach and hypersonic aircraft aim to deliver capabilities at a pace not seen in the U.S. since the 1950s.

Hermeus is also developing its air breathing propulsion test facility called HEAT (High Enthalpy Air breathing Test) at Cecil Airport in Jacksonville, FL. This facility will be capable of testing high Mach propulsion systems, enabling Hypersonic flight.

We are seeking a technically fluent and strategically minded Product Manager to lead the development and execution of our Propulsion Test Capability Build out and Service offering—enabling rapid and scalable propulsion testing for DoD, industry, and research customers.

This role is responsible for extracting customer problems, shaping the product vision, defining core capabilities, aligning engineering requirements, developing pricing strategies, authoring proposals, and managing strategic supplier relationships. The Product Manager will work cross-functionally with engineering, program and test management, contracting, and business development teams to ensure that the facility capability and test offering is both technically robust and contract-ready for government acquisition pathways.

This is a high-impact role that blends product development, engineering acumen, business strategy, and government contracting fluency to help operationalize and commercialize advanced propulsion test capabilities.

• Customer & Stakeholder Engagement
• Work cross-functionally with internal teams to align product capabilities with current and emerging DoD and commercial test requirements.

• Source and evaluate potential strategic suppliers and subcontractors for key components and/or services (e.g. design, construction, instrumentation, integration hardware, support services).
• Define and manage supplier scopes, schedules, pricing, and risk mitigation strategies.
• Develop long-term supplier relationships that align with capability, reliability, and scalability goals.

• Bachelor’s degree in Engineering (Mechanical, Aerospace, Systems, or related).
• 7+ years of experience in product development, technical project management, or system integration within aerospace, defense, or R&D environments.
• Prior experience and familiarity with propulsion systems, engine test programs or ranges, test environments, and ground test facility operations.
• Demonstrated experience in developing technical proposals and statements of work for DoD customers.
• Strong understanding of DoD acquisition pathways, including OTAs,…
