Isar Aerospace is seeking a Principal System Architect for Reusability to lead the exploration and architectural development of reusable-launcher design space. In this role, you will drive convergence toward a coherent vehicle architecture by synthesizing models and analyses from specialist teams across disciplines. You will identify the most valuable design paths, direct follow-on investigations, and make high-impact architecture decisions that balance performance, development risk, operability, lifecycle cost, and profitability.
Your responsibilities include:
- Leading multidisciplinary architecture trades and design decisions with company-wide scope
- Interpreting integrated model outputs, assessing their assumptions and limitations, and translating findings into actionable architecture decisions
- Guiding exploration of the reusable-launcher design space and driving technical convergence
- Setting direction under uncertainty and creating cross-functional alignment without relying on line authority
- Communicating complex technical strategy to engineering, program, and executive audiences
- Applying systems-engineering and configuration-management expertise to lifecycle cost and operational economics trades
Isar Aerospace is a venture-backed New Space company focused on providing sustainable, environmentally friendly launch solutions for small and medium-sized satellites into Low Earth Orbit.

- Extensive launch-vehicle architecture experience, including direct work on rocket development programs
- Demonstrated experience with reusable launch vehicles, recovery architectures, or reuse-driven vehicle design
- Proven ownership of multidisciplinary architecture trades and high-impact design decisions
- Deep understanding of reusable-launcher architectures, subsystem interactions, and dependencies connecting vehicle design, recovery, and operations
- Strong multidisciplinary knowledge across propulsion, fluids, structures, avionics, trajectory, production, logistics, launch operations, and refurbishment
- Ability to interpret integrated model outputs, judge their assumptions and limitations, and translate them into architecture decisions
- Sound systems-engineering and configuration-management knowledge with strong judgment in lifecycle cost, operational economics, and profitability trades
- Decisive cross-functional leader who can challenge local optima, set direction under uncertainty, and create alignment without relying on line authority
- Clear strategic communicator across engineering, program, and executive audiences
- Fluent English, both written and spoken
BONUS SKILLS:
