Hermeus is an aerospace and defense technology company founded to radically accelerate air travel by delivering hypersonic aircraft. The company aims to develop hypersonic aircraft quickly and cost-effectively by integrating hardware-rich, iterative development with modern computing and autonomy. This approach has been validated through design, build, and test of the company’s first combined turbojet-ramjet engine and is now being scaled through its first flight vehicle program, Quarterhorse. Hermeus is also developing Darkhorse — an uncrewed hypersonic aircraft designed to deliver unique asymmetric capabilities to the warfighter.

We are seeking a highly motivated Finance Manager to join our growing team. This individual will be a key business partner across engineering, operations, and leadership—driving clarity through forecasting, enabling resource scaling, and supporting investment in production capacity. The ideal candidate has a strong FP&A foundation, thrives in a fast-paced hardware environment, and enjoys shaping processes as much as delivering insight.

Responsibilities:

FP&A Leadership: Lead budgeting, forecasting, and variance analysis across company functions, with a focus on hardware R&D, engineering, and operations.
Hardware-First Business Modeling: Partner with technical teams to model program costs, NRE, and capital expenditures as we transition from prototype to production.
Business Partnering: Serve as a strategic finance partner to engineering, supply chain, and operations - enabling data-driven decision-making.
Scenario Planning: Develop and maintain dynamic models for product launches, production scaling, and fundraising support.
Financial Systems & Process: Help mature internal FP&A processes and systems to support multi-year planning, reporting automation, and program profitability tracking.
Cross-Functional Influence: Collaborate with technical and operational teams to ensure our near-term resourcing is aligned and sufficient to support our long-term strategic plan.

Qualifications:

6+ years of experience in FP&A, strategic finance, or related roles; experience in defense, aerospace, or hardware-intensive startups is highly preferred.
Strong understanding of hardware R&D lifecycles, new product introduction, and manufacturing concepts.
Demonstrated success in budgeting, forecasting, and building scalable financial models.
Proven ability to partner cross-functionally and translate technical plans into financial outcomes.
Advanced proficiency in Excel and financial modeling; experience with tools like Adaptive Insights or similar is a plus.
Experience supporting Series B-D startup growth stages and capital deployment planning is a plus.
Eligibility for a security clearance may be required depending on program needs.
