Propulsion Systems Engineer

The propulsion systems engineer designs and analyzes liquid propulsion systems. Responsibilities include planning propellant loading and consumption based on flight plans, examining propellant tank pressure plans, and setting requirements for equipment based on the propulsion system design.

The role works with component design teams to conduct and evaluate performance tests for equipment. It also involves developing propellant tank pressure control systems, planning launch operations focused on the vehicle propulsion system, and modeling the vehicle propulsion system and ground plant equipment to evaluate dynamic behavior.

Additional responsibilities include planning, executing, and evaluating stage combustion tests. The propulsion systems function integrates the rocket engine, tanks, avionics, and related systems so that the vehicle can produce the propulsion needed for flight. The team covers large-scale launch and stage combustion test planning and execution, propulsion system design and analysis, equipment and component design and development, and operations from component design through launch activities.

The work location is the company’s Tokyo Second Branch in Koto-ku, Tokyo. The posting states that the scope of duties may change to duties designated by the company.
