Senior Systems Engineer ESM / ELS

Who we are Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.   As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.   We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers.  We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.   The role We  are   developing  an  advanced   airborne   platform   with   integrated  Electronic Support and Electronic Warfare  capabilities .  We   are   looking  for an  experienced   engineer  to  lead  the  technical   definition , design, and  integration  of the  platform's  Emitter Location System.     The  role   focuses  on the  complete   direction-finding   chain :  from   antenna -array  architecture  and  antenna -element  placement  to  signal   processing ,  Direction -of-Arrival  estimation , geolocation, and system-level  co -design  with  the Radar  Warning  Receiver.     You will  work  at the  intersection  of  antenna   engineering ,  radar   signal   processing , Electronic Support Measures,  navigation ,  aircraft   integration , and real-time  mission   systems .     The day-to-day Define the architecture  and system-level  requirements  of an  airborne  Emitter Location System. Translate  operational  emitter-detection  and geolocation  needs   into   measurable   technical   requirements . Develop  and  assess   antenna -array  concepts  for  airborne   direction   finding . Define the number , type,  geometry ,  orientation , and  placement  of  antenna   elements  on the  aircraft . Analyse array   performance   across  the  required   frequency   range . Assess  the  impact  of:    - Element spacing    - Array aperture    - Phase- centre  stability    - Mutual coupling    -  Airframe  shadowing    -  Structural  blockage    -  Reflections  and multipath    - Installation- induced   amplitude  and  phase  errors    - Polarisation mismatch Balance direction-finding   accuracy , angular  ambiguity ,  frequency   coverage ,  installation   constraints , and  platform   size . Develop   calibration   concepts  for  antenna , RF- channel , and  installation-related   errors . Define requirements  for  coherent   multichannel  RF  reception ,  channel   synchronisation ,  phase   matching ,  amplitude   matching , and  timing   accuracy . Develop  and  evaluate   algorithms  for:    - Amplitude- comparison   direction  finding    - Phase- interferometric   direction  finding    -  Correlative   direction  finding    - Monopulse techniques    - Beamforming    - MUSIC, ESPRIT, Capon, and  related  high-resolution methods    - Multi- baseline  and multi- frequency   ambiguity  resolution    -  Wideband  and  frequency -agile  emitter   direction  finding Develop  robust  Direction -of-Arrival  estimation   methods  for  dense  and  complex   electromagnetic   environments . Address   challenges  such as:    - Multiple  simultaneous  emitters    - Co- channel  signals    - Low signal-to- noise  ratio    - Short-duration and low- probability -of- intercept  signals    -  Frequency -agile and pulse-agile radars    -  Multipath  and  platform-induced  interference Define confidence   metrics  and  uncertainty   estimates  for  Direction -of-Arrival  measurements . Develop   emitter  geolocation  methods   using   successive   Direction -of-Arrival  measurements  and  platform   motion . Integrate   aircraft   position ,  attitude ,  heading ,  timing , and  navigation   uncertainties   into  the  emitter -location  solution . Define interfaces   between  the Emitter Location System, Radar  Warning  Receiver, ESM  receiver ,  mission   computer ,  navigation   system , and  other   mission -system  components . Develop  a  coherent   system   concept  in  which  the Radar  Warning  Receiver and Emitter Location System  share   receiver   resources ,  detections ,  signal   descriptors ,  tracks , and  threat   information   where   appropriate . Assess  the trade-offs  between   wideband   threat   warning ,  accurate   direction   finding ,  emitter   identification , and geolocation
