GNC Engineer Lead - Oasis-1 Mission (Space Resource Program)

This role is part of Advanced Concepts and Enterprise Engineering (ACE), supporting Blue Origin's mission of millions of people living and working in space for the benefit of Earth. The team fosters innovation and drives engineering workflows of the future, shared solutions and standards, simplicity and lower costs, and manufacturable design.

We believe that to preserve our planet, humanity must expand beyond our current limits, venturing into space to explore and harness new energy and material resources. In pursuit of this vision, we invite you to join our Space Resources Program, working alongside Blue Alchemist, Blue Origin's initiative to enable lunar surface power production and building blocks for humanity from local materials. The Space Resources Program encompasses multiple projects; in this role, you will contribute across the portfolio, including the current Blue Alchemist effort and future initiatives. We're dedicated to developing and demonstrating Prospecting and In Situ Resource Utilization (ISRU) technologies for the Moon, Mars, and beyond. If our mission resonates with you and you are eager to contribute, you could be the perfect addition to our inclusive, open-minded, and forward-thinking team.

In this hands-on role, you will work in a fully in-person capacity at our Los Angeles facility. You will serve as a GNC (Guidance, Navigation, and Control) Engineer, designing, implementing, and validating guidance, navigation, and control algorithms for a lunar prospecting mission, Oasis-1. You will develop attitude and orbit determination and control; perform trajectory dispersion modeling, implement data integration across flight sensor and ground station measurements; define control mode logic ; build closed-loop and Monte Carlo simulations; and integrate with flight software and hardware-in-the-loop (HIL) benches. You will own GNC performance budgets and acceptance criteria, contribute to ConOps for navigation, support operations readiness, and provide on-console support during commissioning and anomaly resolution. You will collaborate closely with Software, Systems, Instruments, Design & Integration, Mission Assurance/Quality, and external partners to deliver secure, reliable end-to-end operations.

We value self-motivated, hands-on leaders who can find practical solutions to abstract problems. Our teams work in fast-paced cycles of design, analysis, and operations to deliver scalable solutions. We're looking for someone adaptable, willing to take action, eager to learn, and committed to a highly dedicated and open-minded team of team players working together, all while embracing a culture of safety and quality. Your creativity, innovative spirit, and ability to navigate changing requirements are crucial.
