Radio Frequency Engineer

Have designed and integrated RF systems in a professional engineering context, ideally within aerospace, defence, or another demanding, safety-critical domain

Understand RF fundamentals deeply enough to reason from first principles, propagation, antenna theory, link budgets, modulation schemes, noise, and interference

Have hands-on experience with RF test and measurement equipment, and are comfortable debugging real hardware, not just simulation output

Have worked on systems that need to survive a contested or degraded RF environment, or can reason confidently about what that requires even without direct experience

Can interpret complex datasheets and specifications for RF components (amplifiers, filters, mixers, antennas) and translate them into sound design decisions

Collaborate effectively across disciplines, electronics, software, systems and communicate clearly in written and spoken English

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.

Experience with electronic warfare (EW), signals intelligence, or counter-UAS RF systems

Experience with radar or seeker RF front-end design

Familiarity with SDR (software-defined radio) platforms and associated toolchains (GNU Radio, MATLAB RF toolbox, or equivalent)

Experience with antenna design and simulation tools (e.g. HFSS, CST)

Exposure to relevant standards and spectrum regulations for defence or aerospace RF systems

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 defence 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 practise 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
