Job description

As a Radio Frequency Engineer in the Research & Development department, you’ll work on new developments for the next generation of ISISPACE spacecraft. Together with your colleagues you will both design and verify RF systems as they progress from concept to deployment. You will be responsible for the RF performance of spacecraft equipment, as well as addressing Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) concerns.

Your main responsibilities:

• Design of RF systems for our spacecraft, including component selection and architecture definition.

• Collaboration with electronics, software, and mechanical engineers to build prototypes and engineering models.

• Simulation of proposed systems in order to inform the design process.

• Develop and execute test plans to validate RF system performance and ensure compliance with requirements.

• Analyse data from RF tests and simulations to diagnose issues, optimize system performance, and propose innovative solutions.

• Identify and mitigate RF-related issues, such as interference, noise, and EMI/EMC.

• Prepare detailed technical documentation, including design specifications, test reports, and compliance documentation.

Job requirements

Prerequisites:

• Technical Education with a Radio Frequency engineering component (e.g BEng, BSc, or MSc); or equivalent educational / practical background.

• Demonstrable experience of designing and building RF systems to a high standard.

• At least 2 years of experience in RF engineering, RF system design or a related field.

• In-depth knowledge of RF theory, microwave engineering, antenna design principles.

• Proven experience with RF system simulation and modelling tools (e.g., CST, Python).

• Experience with RF test equipment (e.g., spectrum analysers, network analysers, oscilloscopes) and EMI/EMC testing equipment.

• Experience with designing for EMI/EMC compliance, including knowledge of grounding, shielding, filtering, and layout techniques.

• Good communication skills in English (spoken and written).

• Ability to work independently, think critically, and manage multiple projects simultaneously.

Desired but not essential experience:

• Familiarity with regulatory requirements and technical standards (e.g., CISPR, MIL-STD, ECSS, CCSDS, ETSI, ITU).

• Familiarity with PCB layout and design for RF systems.

• Hands-on experience with developing and prototyping RF and analogue electronic systems and / or antennas.

• Experience in developing software tools for RF and EMI/EMC testing and analysis.
