Director of Systems Engineering

About Epirus 

Epirus is a high-growth technology company dedicated to overcoming the asymmetric challenges inherent to the future of national security. Epirus' flagship product, Leonidas, is a software-defined system built using intelligent power management techniques which allow power-hungry systems to do more with less.  

Job Summary: We are looking for a Director of Systems Engineering will build and scale Epirus' Systems Engineering organization and establish the technical discipline that enables us to rapidly develop, integrate, and field complex HPM systems. This leader will develop a pipeline of Chief Engineers and technical leaders who own systems from concept through verification and deployment, while establishing architecture, requirements, integration, and verification practices that allow hardware, software, manufacturing, and test teams to execute as one. You won't inherit a mature Systems Engineering playbook—you'll help write it. Reporting to the Vice President of Engineering, the Director will lead a multidisciplinary team spanning systems engineering, test engineering, and modeling and analysis; provide system-level technical direction and architectural governance; and empower Chief Engineers and senior technical leaders to own product and subsystem architectures. 

Responsibilities:  

• Lead and develop a multidisciplinary Systems Engineering organization, establishing a culture of technical excellence, accountability, innovation, and collaboration.  

• Build and scale Systems Engineering processes, capabilities, and talent pipelines to support a growing product portfolio.  

• Serve as the senior system-level technical authority, providing architectural leadership and driving cross-functional technical trade-offs across performance, cost, schedule, manufacturability, and mission requirements.  

• Lead system architecture reviews, interface definition, technical trade studies, and risk management to identify and retire key technical and integration risks early.  

• Provide technical leadership across system integration, verification & validation, modeling, analysis, and test, ensuring system performance is measurable and validated against requirements and mission objectives.  

• Establish technical baselines, readiness criteria, documentation standards, and clear ownership across Systems Engineering, hardware, software, manufacturing, and test.  

• Partner closely with Hardware, Software, Manufacturing, Technical Program Management, and Chief Engineers to align technical strategy, product goals, resources, dependencies, and execution milestones.  

• Represent Systems Engineering in internal and external technical reviews and engage directly with customers and stakeholders to ensure solutions remain aligned with requirements, architecture, and mission objectives.
