The short version You’ll help build a completely new RF and sensing capability on top of Kelluu’s autonomous airship platform. This is a hands-on, curiosity-driven role where you prototype, experiment, and turn raw RF signals into situational awareness — taking our airship capabilities to a level that hasn’t been done before. 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:
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:
By 6 months:
By 12 months:
What We’re Looking For You’ll thrive here if you have:
Even better if you also bring:
What You Get The opportunity:
The practicalities:
The kind of place this is Kelluu is a dual-use deep-tech company at the intersection of autonomy, AI, and aerial intelligence. We build technology that serves both national security and society, and we take that responsibility seriously.
We’re scaling fast, which means you’ll have real influence on how things are built. The flipside: things move quickly, priorities shift, and everyone wears a few hats. If you want a finished playbook and a clear lane, this probably isn’t the right fit. If you want to write the playbook yourself, it might be exactly right.
We use AI tools extensively, not as a gimmick, but because it lets a growing team move faster than anyone expects. We expect everyone to be curious about how to work smarter.
Details
Due to the nature of our business in the defence and dual-use sectors, the selected candidate must successfully pass a standard security clearance. Furthermore, certain roles are subject to international export control regulations (e.g., EU Dual-Use or ITAR), which may impose specific requirements regarding the candidate’s citizenship and background.
