Main function and scope:

We are seeking a Space Systems Engineer to support the development of advanced space systems, with a strong focus on avionics, payloads, communications, embedded systems, and end-to-end requirements decomposition.

Core functions:

· Decompose mission and system-level needs into clear, traceable, and verifiable requirements for avionics, payloads, HW, FW, RF, SW, and EGSE.

· Define and manage system, subsystem, unit, and interface requirements across the full project lifecycle.

· Support avionics and payload architecture definition, including on-board processing, data handling, RF chains, embedded electronics, and flight software interfaces.

· Develop and maintain ICDs, requirements traceability matrices, verification matrices, technical budgets, and review documentation.

· Coordinate with HW, FW, SW, RF, mechanical, AIT, quality, and project teams to ensure coherent system design and implementation.

· Define verification logic, test methods, success criteria, and evidence needed to close requirements.

· Support integration, functional testing, environmental testing, EMC/RF testing, and end-to-end payload validation.

· Review design outputs, test results, anomalies, non-conformances, and deviations against system requirements.

· Identify and manage technical risks, assumptions, dependencies, trade-offs, and open points.

· Support customer reviews, subcontractor coordination, technical proposals, and compliance matrices.

Required experience and candidate profile:

-Degree in Aerospace Engineering, Telecommunications Engineering, Electrical Engineering, Electronics Engineering, Computer Engineering, Physics, or a related technical field.

-+5 years of experience in space systems engineering

Technical Requirements:

Training / specific knowledge required in:

· Experience in systems engineering for complex technical products, preferably in space, aerospace, defence, telecommunications, or high-reliability electronics sectors.

· Strong understanding of requirements engineering, system architecture, interfaces, and verification processes.

· Familiarity with avionics, payload electronics, embedded systems, RF systems, or spacecraft subsystems.

· Ability to work across multiple domains, including hardware, firmware, RF, software, electrical interfaces, and test systems.

· Experience preparing or reviewing technical documentation

Nice-to-have training / specific knowledge:

· Experience with space project lifecycle phases, including concept, design, development, qualification, acceptance, launch, and operations.

· Knowledge of ECSS standards or equivalent aerospace development standards.

· Experience with requirements management tools such as DOORS, Jama, Polarion, Valispace, Codebeamer, or similar.

· Experience with MBSE tools or methodologies, such as Capella, Cameo, SysML, or Arcadia.

· Familiarity with payload or avionics technologies such as:

-OBCs and data handling systems

-FPGA-based processing

-High-speed digital interfaces

-ADCs, DACs, clocks, timing, and synchronization

-RF transceivers, antennas, modems, and link budgets

-Embedded Linux, RTOS, bare-metal firmware, or flight software

-SpaceWire, CAN, UART, SPI, I2C, Ethernet, LVDS, SerDes, CCSDS, or similar protocols

· Experience supporting AIT campaigns, environmental testing, EMC testing, or RF testing.

· Knowledge of FMECA, FDIR, reliability, safety, radiation, derating, and parts selection for space applications.

The position is located at our headquarters in Madrid, at Calle Serrano Galvache, 56.
