ABOUT KELLUU We are turning the real world into a digital one, with accuracy down to the smallest detail. Imagine a near future where everything you see can be explored through data delivered by Kelluu, and where AI works continuously across that data to find what you need to know. Everything turned into answers. We’re a Finnish deep-tech company, headquartered in Joensuu with offices in Helsinki and Tampere. The team is growing fast, the goals are ambitious, and we’re hiring people who want to build something that matters. Our technology is flight-proven and operational. We’re a NATO DIANA Phase 2 alumni with several thousands of hours of autonomous BVLOS flight experience, active programmes across multiple NATO nations, and a rapidly growing team. We operate in both defence and civilian markets: the same technology that supports border security also monitors critical infrastructure and the environment. P.S. We just raised 15M€ Series A. WHY THIS ROLE EXISTS Kelluu is building a new RF and radar domain from scratch to dramatically expand what our airships can sense, detect, and understand. This role exists to explore, prototype, and validate RF-based sensing concepts early — before dedicated hardware teams scale it further. WHAT YOU’LL OWN You’ll be responsible for turning RF physics into working signal processing and detection algorithms, using real-world data and rapid prototypes. The impact you’ll have: - Build and prototype RF, radar, and signal processing algorithms using existing hardware (e.g. SDRs) and real measurement data - Translate RF physics and sensing theory into practical, testable software systems - Develop early detection, estimation, and tracking capabilities that contribute directly to airship situational awareness - Experiment, test, and iterate — shaping what RF-based sensing on an airship can realistically do - Contribute to antenna and RF concept development for airship integration, in close collaboration with hardware-focused colleagues YOUR TEAM You’ll work closely with Kelluu’s core airship, autonomy, and systems engineers in Joensuu. The RF domain is being built now, which means significant ownership and influence from day one. WHAT SUCCESS LOOKS LIKE By 3 months, you will have: - A strong understanding of Kelluu’s airship platform, sensing goals, and constraints - First RF or signal processing prototypes running on real data By 6 months: - Demonstrated detection or estimation algorithms validated through experiments - Clear direction on which RF/radar concepts are worth scaling further By 12 months: - Meaningful RF-based sensing capability integrated into Kelluu’s roadmap - A foundational RF algorithm stack others can build on WHAT WE’RE LOOKING FOR You’ll thrive here if you have: - Strong fundamentals in physics or engineering (electromagnetics, signal processing, or applied mathematics), at MSc level or equivalent - Solid mathematical maturity: signal processing, linear algebra, probability and statistics at university level - An experimental mindset, with evidence of building, testing, and iterating on real systems - Experience solving hard technical problems (thesis, research project, competition, open-source work, or comparable) - Sufficient programming ability to prototype and iterate quickly, primarily in Python - Genuine curiosity about radar, RF, and sensing — prior professional experience is not required Even better if you also bring: - Experience with SDRs or other RF hardware - Exposure to radar, RF, or wireless signal processing - Familiarity with detection and estimation concepts (CFAR, Kalman filtering, hypothesis testing) - Experience with clutter suppression or noise reduction techniques - Knowledge of positioning concepts such as TDoA, PDoA, FDoA, or direction finding WHAT YOU GET The opportunity: - Build a brand-new RF and sensing domain inside a growing deep
