Working closely with development, engineering, construction and finance teams, the Project Engineer ensures that technical requirements are clearly defined, properly implemented and aligned with project schedules and budgets. This role is ideal for an engineer with early career experience in utility scale renewable projects who is eager to deepen technical expertise while contributing to the delivery of complex infrastructure projects.

Lightsource BP Renewable Energy Investments Ltd

Project Engineer

Set and defend the bus specification against the loads: PPU input range, inrush and ripple at thruster ignition, bus stability at the PCDU–PPU interface, and the cold-eclipse-exit overvoltage case that sets the HV design point. You will own the spacecraft’s electrical backbone: an ~8 kW solar array feeding a high-voltage bus that drives electric propulsion, a low-voltage bus that runs everything else, and the power conditioning, battery management and distribution hardware in between.

Power Systems Engineer

Workable

Solve the hard local problems: a high-power electric-propulsion power unit rejecting hundreds of watts, GaN RF amplifiers, a battery with a tight temperature window, a xenon tank whose pressure sets a temperature limit, and a flexible solar array that swings 200 °C per orbit early in the mission. Do the component-level thermal design for in-house electronics boxes with the avionics and power teams: board-to-chassis conduction paths, TIM selection, junction-temperature predictions that feed radiation derating.
