STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains.
We design, develop, and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective
— providing operators with a decisive edge in contested environments.
We are focused on delivering deployable, high-performance systems — not future promises. In a time of rising threats, STARK is
bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe, today
You will own the product roadmap for one of the hardest and most consequential capabilities in our autonomy stack: how our
platforms know where they are when GPS isn't available or can't be trusted. You won't be writing the estimation filters yourself,
but you'll be translating deep technical complexity into a roadmap that ships, and making sure engineering effort lands on the
problems that matter most. Success looks like a localization capability that improves predictably, release over release, with
clear priorities that the technical team trusts.

JOIN US AS A PRODUCT MANAGER (ALL GENDERS) IN OUR CONNECTIVITY TEAM ON A SHARED JOURNEY THAT MATTERS! The Connectivity Team builds and operates the backbone of vehicle‑to‑platform communication.
