About this job

We are recruiting a Power Conditioning Engineer for Sapienza to work on our Customers Site (ESA-ESTEC( porividing support to the TEC Directorate.

Responsibilities

• The design, development and test of spacecraft power systems for on-board applications. This work encompasses the definition of centralized power systems having overall power levels up to 25 kilowatts, together with their interfaces with respect to solar arrays and batteries, the attendant power distribution/protection equipment and pyrotechnic activation functions. Detailed tasks include the overall system design necessary for the development of fault tolerant power control and distribution concepts, the detailed design of the power regulators and the identification/use of tools and methods for ensuring dependable design and verification.
• The development of simulation blocks for system analysis (batteries, solar cells & arrays,power control and distribution units) useful for the independent evaluation of critical power and energy budgets (in support to running projects of the Agency).
• Support to laboratory activities concerning design and development or verification of circuitsfor power management and distribution (solar array and battery conversion electronics, power distribution and protection electronics, power conversion for generic and specific purposes, including redundancy and protections).
• Active involvement in critical R&D activities support (by simulation, worst case analysis and laboratory testing of the overall system or of the most critical sub-units).
• Assisting to the development and validation of worst-case simulation blocks for electricalequipment analysis (converters, shunt regulators, current limiters, protections, criticaltelemetry or telecommand functions) useful for the independent check of the most criticalequipment functionality and performances, in support to all programmes reviews where the power conditioning section is involved.
• The development and verification of high voltage design technologies and associated power converters, suitable for application as Electronic Power Conditioners (EPCs) for specialized spacecraft payloads such as Travelling Wave Tube Assemblies (TWTA’s) and Electric Propulsion Concepts.

Profile

• Master’s in engineering (Electrical, Electronic or Physics), together with a good experience of digital and analogue electronics and control theory.
• At least 04 years of relevant work experience
• Proven experience in the domain of power conditioning electronics together, with ‘handson’ knowledge of the circuit design of such systems
• Experience in the development of computer models, especially with SPICE-basedsimulators
• Knowledge and the experience on High Voltage power conditioning for space applicationconstitute an asset.
• Proven experience in FPGA and microcontroller programming.
• Proven experience in the design of power converters with GaN semiconductors
• Knowledge on space power conversion systems will be an asset
• Fluent in English; knowledge of another ESA member-state language is an asset
