About the role

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. As the Lead Engineer for Passive RF Sensing, you will direct the end-to-end integration and performance of airborne electronic surveillance systems, including Radar Warning Receivers, from initial requirements through to flight test. Your primary focus will be to translate mission threats into concrete sensor requirements, define the antenna architecture for optimal direction-finding, and manage emitter library data. You will guide co-site coordination to protect sensitive receivers from onboard transmitters and direct the verification campaign to deliver a fully qualified sensor system. The day-to-day Direct the integration and performance of passive RF sensors from initial requirements through to flight test to ensure operational readiness Translate mission threat scenarios into measurable sensor requirements and define antenna architectures for optimal direction-finding Specify and validate sensor performance, driving direction-finding performance analysis and RF distribution Oversee library and classification support, managing emitter parameter sets, frequency agility handling, and confidence metrics Guide co-site and electromagnetic compatibility coordination with onboard transmitters to implement desense protection, blanking, and filtering Execute verification and test campaigns with a focus on installed sensor performance, coordinating data interfaces with software and avionics teams Manage technical supplier relationships, reviewing specifications, acceptance tests, and change requests to track issues to objective closure You should apply if you Hold a degree in Electrical Engineering, Aerospace Engineering, Systems Engineering, or a related discipline Have delivered passive RF sensors for airborne or complex platforms from concept to integration Understand threat radar phenomenology and can convert scenarios into measurable sensor requirements Possess practical expertise with direction-finding architectures, error budgeting, and calibration Can specify and validate receiver performance, interpreting laboratory and flight data accurately Have implemented electromagnetic compatibility mitigation on platforms with strong transmitters

Requirements

• Bring established familiarity with emitter libraries and classification workflows
• Have practical experience defining interfaces to mission computers and avionics systems
• Note: We operate in an industry where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don't meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.
• Join Helsing and work with world-leading experts in their fields
