AI Research Engineer - Reinforcement Learning

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 At Helsing we deliver AI-based capabilities and the enabling infrastructure that allow semi-autonomous platforms to localise, navigate, and perceive the world in real time. You will have the unique opportunity to shape the future of AI in one of the most challenging sectors, where performance needs to be paired with high generalisation capabilities and strong robustness against adversarial attacks. You will build the autonomy brain for a cutting-edge autonomous aerial platform that will actually take flight. You will develop and integrate state-of-the-art reinforcement learning agents into the operational systems of our own Unmanned Combat Aerial Vehicle, the CA-1 Europa , as part of the groundbreaking Centaur project. This is a unique opportunity to take ownership of novel autonomous systems designed from the ground up, owning the full pipeline from large-scale simulation training through to real-time deployment on flight-ready hardware. You should apply if you Hold a MSc in Reinforcement Learning, Robotics, Automation and Control, or a closely related field, with a strong focus on sequential decision-making and autonomous systems. Have hands-on experience building, training, and deploying reinforcement learning agents. You have iterated on a policy beyond simulation and understand what it takes to make learned behaviour reliable in a real operational system. Are deeply familiar with modern RL and multi-agent RL techniques, including but not limited to: model-free methods (eg. PPO, SAC), population-based training, handling of partial observability and long horizons. Have experience integrating RL policies into high-performance runtime systems, with a solid understanding of the latency and throughput constraints that come with real-time autonomous decision-making. Possess solid software engineering skills, writing clean and well-structured code in Python and/or languages like Rust or modern C++, and have experience deploying AI software to production including testing, QA, and monitoring. Have excellent communication skills and the ability to report and present research findings clearly and efficiently, both internally and externally. Are passionate about keeping up to date with current research and enjoy reimplementing and extending state-of-the-art approaches in deep reinforcement learning. Note: We operate at an intersection 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. Nice to have PhD in Reinforcement Learning, Multi-Agent Systems, Automation and Control, Robotics, or a related field, with publications in top-tier venues . Experience with large-scale distributed RL training frameworks, the infrastructure challenges of running thousands of parallel simulation environments, and gpu-based simulators. Experience modelling and training multi-agent controllers using state-of-the-art techniques, including emergent coordination, competitive self-play, or decentralised execution with centralised training. Familiarity with flight dynamics, aerospace systems, or guidance, navigation, and control (GNC) concepts. Experience deploying AI software to safety-critical production systems, including formal verification, testing pipelines, and runtime monitoring. Join Helsing and work with world-leading experts in their fields 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. What we offer Competitive salary and VSOP options Relocation support : up to €2,500 and 4 weeks temporary accommodation Learning : €500/£450 yearly allowance Health & wellness : gym membership and mental health support (Nilo.health) Social : regular company events and monthly social allowances Enhanced parental leave : 22 weeks fully paid for primary caregivers & 6 weeks for secondary caregivers Family support: 5 days of paid family emergency leave, 100% remote work option during pregnancy and phased return to work These are the core benefits across all locations, there may be additional benefits in certain locations.
