Senior Robotics Controls Engineer

Location: Berlin (Onsite)

About Us

We are a defense technology startup based in Berlin , building the next generation defense layer against aerial threats. Our team develops mission-critical systems that combine hardware, software, and sensing to operate reliably in complex real-world environments.

As an early-stage company operating in stealth mode, we place strong emphasis on engineering rigor, mathematical precision, and high-performance system design.

Role Overview

We are seeking a Senior Robotics Controls Engineer (Regelungstechnik) with a strong focus on optimal and model-based control to design and implement the control architecture for our high-precision aiming and stabilization systems.

You will take ownership of the control design for a:

• 2-axis fast steering mirror

The system must achieve sub-milliradian precision under high acceleration and dynamic disturbances , enabling accurate target tracking and beam stabilization in real-world environments.

This role emphasizes:

• Constrained real-time control
• Model-based system identification

You will work closely with computer vision, mechanical, and optics engineers to transform tracking data into stable, deterministic, real-time actuation.

This position requires onsite work and eligibility for German security clearance.
