At ispace U.S., we’re not just going to the Moon—we’re redefining how we get there. Our missions push the boundaries of human and robotic exploration, driven by our belief: “Expand our Planet. Expand our Future.” By providing cost-effective lunar transportation, we are pioneering a future where space is within reach for scientific discovery, commercial ventures, and sustainable exploration.
With locations in Japan, Luxembourg, and the United States, ispace is rapidly growing and leading the way in lunar exploration and development. Our U.S. branch is based in Englewood, Colorado, and focuses on high-capacity payload lunar landers designed to support future lunar missions. Our team is made up of innovators, problem-solvers, and visionaries committed to making space more accessible and fostering the next generation of space exploration.
Let’s go to the Moon together! Our team is growing, and we are actively seeking talented individuals who share our passion for space.
As a Senior Systems Engineer at ispace US, you'll own the full technical backbone of lunar lander and satellite development — from requirements through verification, launch, and beyond. That means driving ConOps definition down to the subsystem level, maintaining technical budgets and interface control, and leading risk and reliability management across the entire spacecraft lifecycle. You'll chair technical reviews, lead dFMEAs, and own FDIR architecture — serving as the thread that holds every discipline together from PDR to flight. This is end-to-end systems ownership on missions that go to the Moon.
Key Responsibilities
- Take ownership, lead, and coordinate: Requirements, V&V planning, Technical Budgets, Interfaces, Configuration Management, system-level analysis, trade studies, Risk Management, FDIR, failure, fault, and system reliability management through the entire life cycle of a spacecraft development program
- Lead efforts across all disciplines in defining Lander ConOps down to subsystem level requirements
- Lead and coordinate Techncal Reviews, dFMEAs and other failure and risk identification & mitigation activities throughout all phases of the life cycle
- Lead and collaborate with functional and subsystem teams on systems engineering tasks, trade studies, and seeking opportunities to increase performance
- Seeks feedback from interdisciplinary teams and experts to ensure program success.
- Provide technical guidance and direction to the system and subsystem engineering teams
- Mentor junior systems engineers and guide their technical & career development
- Help expand the company systems engineering knowledge, provide systems learning opportunities to engineers from other disciplines
- Lead the development and streamline best in class work processes for engineering and new product development in an agile, multidisciplinary environment
- Involved in full product lifecycle, ensuring late-stage issues are addressed early in development
- Lead and perform architecture trade studies and analysis that will influence the overall system design and performance
- Support technical proposals for new business and mission opportunities
- Identify and drive design or operational problems to resolution to facilitate reliable and successful operations and reduce technical risk
- Identify and validate entry and exit criteria at key program lifecycle milestones
Required Qualifications
- Bachelor's degree in Aerospace, Mechanical, Electrical Engineering, Computer Science, or equivalent. We will consider an equivalent combination of relevant education and/or experience
- Minimum of 8 years' spacecraft engineering experience with 4+ years in spacecraft systems engineering, ideally during several lifecycle phases and at spacecraft level
- Deep understanding of systems engineering principles and their application in a fast-paced spacecraft development program
- Cross functional, broad experience with several spacecraft and/or launch vehicle subsystems; including both hardware and software systems
- Deep expertise in at least one spacecraft technical area (structures, thermal, mechanical, electrical, avionics, GNC, software, etc.)
- Familiarity with engineering drawings and configuration management
What Makes You Stand Out!
- Engineering Masters degree with emphasis on systems. We will consider an equivalent combination of relevant education and/or experience
- Experience in defining requirements and verification plans for spacecraft systems
- Extensive contributions to the development of a spacecraft, during multiple lifecycle phases
- Extensive experience in integrated testing and change management
- Experience performing FMECA, reliability analysis, and/or hazard analysis
- Experience with common industry standards for spacecraft design, test and integration; including, but not limited to, NASA-STD-5001, NASA-STD-5012, NASA-STD-5017, NASA-STD-5020, SMC-S-005 & SMC-S-016
- Experience working for Aerospace/Space Prime or sub-contractor strongly preferred
- Experience in startup environment a plus
