Senior RF Engineer

Who we are Helsing develops artificial intelligence-enabled capabilities to protect and defend democracies.  We are growing our US operations, cultivating an ambitio u s and committed team of mission-driven professionals to apply their skills to solve challenging problems.   The role AI-driven, autonomous systems cannot replace human decision making. To keep the human in the loop, communication to remote unmanned vehicles is crucial. As an RF Engineer for Communications and Networking, you will work in one of the most contested domains of the modern battlefield:  the electromagnetic spectrum .   You will design, develop, and deploy advanced datalink systems for UAS-to-ground and UAS-to-UAS communications, including point-to-point and mesh network architectures. Your work will ensure robust, encrypted communications links for UAS operating in non-cooperative and contested environments, directly supporting mission-critical operations for US customers.   You will own radio communication end-to-end as part of new product design and iterations on existing systems. You make pragmatic decisions when to integrate available solutions and when to develop new capabilities that shape the contested environment of the frontline RF space. Working closely with systems engineers, avionics teams, and customer-facing program managers, you will be the key to ensuring the right decision can be made at the right time.
