**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.**

**In**ARQUIMEA SPACE** develops **spaceflight parts and equipment for satellites and launchers**. We specialize in thermal control systems, structural panels, optical payloads, avionics, release and deployment mechanisms, and rad-hard microelectronics. Together with our tech partners we provide **high-throughput smallsats and their subsystems**. Our brand-new factory in Madrid is suited to** integrate satellites and constellations**.

We are looking for a **Spacecraft Systems Engineer**with the mission of taking responsability for the design, development, integration, and validation of satellite systems. This includes leading the design and verification of critical subsystems such as:

- EPS (Electrical Power Subsystem)
- Propulsion
- Onboard Data Handling (OBDH)
- AOCS (Attitude and Orbit Control System)
- Communication and TT&C systems
- Associated sensors and actuators

**Tasks to be performed**:

- ** Assess** customer and mission needs to **define system requirements**, technical **parameters**, and **ensure compatibility** of all interfaces.
- **System Architecture**:Develop** and **maintain** the **spacecraft system architecture**, ensuring consistency and alignment across all subsystems.
- **Lead the design** interdisciplinary coherence, **development**, and **verification** of:

- **EPS**: power generation, storage, distribution, and regulation.
- **OBDH**: operational modes, redundancy, FDIR, data buses, TM/TC.
- **Propulsion**: chemical and/or electric architectures, mission integration, and AOCS interfaces.
- **AOCS**: sensors, actuators, control algorithms, operational modes, and redundancies.
- **Communication systems**: telemetry, telecommand, and tracking links, including RF and SDR platforms.
- Perform **trade-off analyses, simulations, and optimization** of mass, power, cost, and performance at system level.
- **Coordinate** hardware and software **integration across subsystems**.
- **Conduct** environmental and functional **validation testing** at spacecraft level.
- **Lead troubleshooting** and anomaly resolution throughout the entire project lifecycle.
- **Prepare** and maintain technical **documentation**: requirements, ICDs, design reviews, and verification plans.

The role requires close collaboration with multidisciplinary teams to ensure that the overall spacecraft architecture meets mission and operational requirements.
- Bachelor's or Master’s degree in Electrical Engineering or Aerospace Engineering or a related field.
- Master’s or PhD Electrical Engineering or Aerospace Engineering related technical discipline is a plus.
- At least 10 years working in spacecraft systems engineering or in key subsystems (EPS, OBDH, Propulsion, or AOCS). Specific expertise in:

- **EPS**: solar arrays, batteries, BMS, power distribution/regulation, EMC, fault tolerance.
- **Propulsion systems**: chemical/electric propulsion, mission integration.
- **OBDH**: FDIR, redundancies, buses, TM/TC, operational modes.
- **AOCS**: sensors, actuators, orbit and attitude control, algorithms.
- **Communications**: TT&C, RF, antennas, protocols (CAN, SpaceWire, Ethernet, RS-4XX).
- **Experience** with requirements **management tools**.
- **Familiarity** with reliability, FMECA, radiation and Worst Case analysis and tools.
- **Knowledge** of **radiation-hardened electronics** and **space-qualified components**.
- Hands-on **experience** with **avionics hardware**.
- **Understanding communication protocols**, such as CAN, RS-4XX, Ethernet, SpaceWire and others.
- **Experience** with **digital**, **analog**, **mixed signal**, and **power design** and **analysis** processes for space programs form a systems point of view.
- Hands-on **experience** with **spacecraft integration** and **environmental testing** (thermal vacuum, vibration, radiation and EMC/EMI).
- **Familiarity** with **antenna and RF** systems for **spacecrafts** TT&C.
- Experience working with product/component developers and vendors supply chain.

The position is **located in** our Headquarters of **Torrejón de Ardoz (Madrid).**

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.
