RF Systems Engineer / EMC Specialist in Bussigny

Select how often (in days) to receive an alert:EPFL, the Swiss Federal Institute of Technology in Lausanne, is one of the most dynamic university campuses in Europe and ranks among the top 20 universities worldwide. The EPFL employs more than 6,500 people supporting the three main missions of the institutions: education, research and innovation. The EPFL campus offers an exceptional working environment at the heart of a community of more than 18,500 people, including over 14,000 students and 4,000 researchers from more than 120 different countries.MissionThe EPFL Space Center is dedicated to promoting excellence in space research, education and innovation. Our young and dynamic team combines deep technical expertise in system engineering, mission design, multidisciplinary project management, astrophysics and space situational awareness.The Space Center leads the work on emission mitigation in HALO (Harmonizing Astronomy and Low-orbit Operations), an ESA-funded project carried out with industrial and academic partners. HALO aims to protect radio astronomy and preserve dark and quiet skies while allowing a sustainable future in space. It develops methods to predict the electromagnetic impact of unintended satellite emissions on astronomical observatories, and studies concepts to reduce unwanted emissions from on-board electronics and RF transmissions.We are looking for an RF systems engineer / EMC specialist to prepare, carry out and validate the project's proof-of-concept experiments on RF emission mitigation.Main duties and responsibilitiesIdentify the main contributors to RF payload interference and define a proof of concept for their mitigation, using existing hardware or designing dedicated breadboardsWrite the investigation and validation test plan, including test setup, procedures and performance criteriaPrepare and run conducted EMC measurements on power and control lines to DC/DC converters and data processing units, with and without dedicated filteringInvestigate unintended electromagnetic radiation (UEMR) from spacecraft electronics via structure, harnesses and unintended antennasCarry out tests at partner facilities and in the EPFL EMC Laboratory, and analyse the results against the defined performance criteriaCompare measurements with predictions from the project's computational models and simulationsDerive recommendations for measurement and validation techniques for serially produced satellites and constellationsWrite technical notes and test reports, and present results at project reviews with ESACoordinate day to day with industrial and academic partnersThe engineer will also have the opportunity to support other Space Center activities, including proposal writing and student space projects.ProfileYou have a Master of Science or a PhD in Electrical Engineering, Telecommunications, Physics, Aerospace or a related fieldYou have hands-on experience in EMC testing, ideally conducted and radiated emission measurements (e.g. to ECSS-E-ST-20-07, MIL-STD-461 or CISPR)You are familiar with RF and microwave measurement equipment: spectrum and network analysers, EMI receivers, LISNs, current probes and antennasYou have experience in RF/EMC design, such as filtering, shielding, grounding and harness designYou have experience with electromagnetic simulation tools (e.g. CST, HFSS, FEKO or equivalent)You can write in Python or Matlab for data acquisition and analysisExperience with space hardware, satellite subsystems or ESA projects is a strong assetInterest in radio astronomy or dark and quiet skies is an assetYou have a good knowledge of English; French and/or German is an assetThe engineer will work with industry partners, EPFL laboratories, ESA and students. They should be curious about space activities, take initiative, work autonomously and enjoy hands-on laboratory work.We offerA young, dynamic, interdisciplinary and international working environmentA vibrant, internationally visible and rising academic institution in space research, education and innovationA privileged contact with state-of-the-art technological developmentsAccess to many continuing education coursesSalary: based on the official Swiss Confederation gridsDirect involvement in an ESA project at the interface of satellite engineering and astronomyAccess to EMC and RF laboratory facilities at EPFL and partner sitesAt EPFL, we believe that people achieve great results when they feel supported, respected and enabled to succeed. By joining our community, you will help shape the future of society through education, research and innovation.We offer an inspiring, international and collaborative environment where your work has real impact and your ideas are valued. Combined with flexible ways of working and attractive employment conditions, we aim to create an environment where everyone can contribute, grow and make a difference.Beyond work, ourcampuses host a vibrantcommunity and unique environment, enriched by initiatives promoting equality, inclusion, diversity, well-being and sustainability as well as an engaging program of cultural, sports and community activities throughout the year.
