Radio Frequency (RF) Engineer

Company

Aerlijn B.V. produces air defense systems in the Netherlands with contracts in NATO countries. We specialize in battle-proven systems that are actively deployed in conflict regions, focusing on reliability and mission readiness. Its mission is to strengthen sovereign air defense through engineering designed for operational effectiveness. We are a dynamic international team.

Your Role

As part of the research & design teams at Aerlijn, our R&D team support all phases of electronic product and system development, from early-stage architecture reviews through production. They are often also involved in field implementation and training for our clients to assure proper installation and usage. This requires in-depth RF knowledge and experience designing wideband microwave modules, including receiver front ends, tuners, up/down converters, switch matrices, and other wireless communication systems fundamentals. Executing this on a day-to-day basis means each engineer will be ready to enact the following duties:

• Design, develop, build, and test systems capable of detecting extremely low amplitude “into the noise floor” as well as detecting high-frequency signals and translating them down to baseband. These systems also convert baseband signals to a higher frequency carrier.
• Analyze, design, test, and build any electronic equipment that operates from high-frequency (HF) through millimeter waves, including existing wireless networks, making certain of its continuous functionality and precision in a range of environments that extend well beyond the laboratory.
• Actively participate in technical teams involved with the design, verification, testing, and production of RF modules at Aerlijn.
• Grow their knowledge of electronic warfare while working with subject-matter experts.

Hard Requirements

• Fluent English
• Authorized to work in the Netherlands
• On-site work setting in Amsterdam or Twente
• Living in the Netherlands currently or willing to relocate (housing is difficult)

Basic skills and requirements:

• RF engineers must use computer software tools such as ADS, HFSS, Microwave Office, Genesys, and Sonnet to design the components, systems, and antennas that make up a typical receive and transmit system. They use test equipment to measure the performance of the RF system: gain, noise figure, VSWR, linearity, and phase noise.
• Bachelor's Degree in electrical engineering (Master's or Ph.D. preferred)
• A radio frequency engineer designs components such as amplifiers (high power, low noise), filters, mixers, couplers, splitters/combiners, antennae, and phase lock loops. Candidates must tune and optimize the performance of these systems.
• Modeling, simulation, electromagnetics, lumped elements, transmission line theory, spectrum, and network analyzer measurements
• Design leading-edge hardware modules with a focus on small size, low noise, wide bandwidth, and/or high linearity.

Advanced skills preferred:

• Experience with RF environments and wireless communications in electronic warfare domains
• Digital signal processing techniques
• Experience in digital communications protocols and signal conversion techniques
• MATLAB (MATrix LABoratory)/Simulink toolsets and/or verification using test vectors from reference models
• Experience leading small- to mid-size teams, with active listening skills, project planning acumen, and accountability for managing and reporting project cost, schedule, and quality
• Experience driving processes and process improvements, including continuous improvement methodologies
• Several certifications and key soft skills preferred

Package
