Note: We encourage you to apply even if you don’t meet all the listed qualifications; ability and impact cannot be summarized in a few bullet points. 

• Designed, built, and evaluated custom antennas for airborne platforms  

• Built, worked on, or implemented a Software Defined Radio solution  

• Experience with specific tactical datalinks such as Link 16, JREAP, CDL (Common Data Link), or Cursor-on-Target (CoT) 

• Familiarity with Mobile Ad-Hoc Networks (MANET) and dynamic mesh routing protocols  

• Knowledge of Electronic Warfare (EW) techniques, anti-jam waveforms, and LPI/LPD (Low Probability of Intercept/Detection) communications 

• Experience with spectrum analyzers and RF test equipment for pre-flight checks and interference mitigation  

• Understanding of MIMO, OFDM, OFDMA transmission schemes and beamforming techniques  

• Experience working with Silvus, Persistent Systems (MPU5), or similar tactical radio systems  

• Knowledge of NATO STANAG communication standards and interoperability requirements 

• Familiarity with ITAR/EAR export control regulations related to communications equipment 

• Experience in the defense industry or contested RF environments  

• Helsing’s work is important. You’ll be directly contributing to the protection of democratic countries while balancing both ethical and geopolitical concerns

• The work is unique. We operate in a domain that has highly unusual technical requirements and constraints, and where robustness, safety, and ethical considerations are vital. You will face unique Engineering and AI challenges that make a meaningful impact in the world

• Our work frequently takes us right up to the state of the art in technical innovation, be it reinforcement learning, distributed systems, generative AI, or deployment infrastructure. The defense industry is entering the most exciting phase of the technological development curve. Advances in our field of world are not incremental: Helsing is part of, and often leading, historic leaps forward

• In our domain, success is a matter of order-of-magnitude improvements and novel capabilities. This means we take bets, aim high, and focus on big opportunities. Despite being a relatively young company, Helsing has already been selected for multiple significant government contracts

• We actively encourage healthy, proactive, and diverse debate internally about what we do and how we choose to do it. Teams and individual engineers are trusted (and encouraged) to practice responsible autonomy and critical thinking, and to focus on outcomes, not conformity. At Helsing you will have a say in how we (and you!) work, the opportunity to engage on what does and doesn’t work, and to take ownership of aspects of our culture that you care deeply about
