ARQUIMEA, we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors.

Our areas of activity are Aerospace, Defense & Security, Big Science, Biotechnology and Fintech.

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.

We're looking for curious, creative, tenacious and collaborative people, eager to do things and unafraid to tackle challenges in order to contribute to improving the society in wich we live.
