Signal Processing Engineer

As a Signal Processing Engineer, you will be responsible for designing and operating the core simulation frameworks that underpin our system and payload design. You will evaluate these frameworks using real signals to ensure our performance guarantees and, ultimately, to enhance the value we deliver to our users.

You will work at the intersection of signal processing, RF systems, and mission engineering:

• Design, implement and maintain high-fidelity simulation environments for RF signal environments, receivers and processing chains on LEO satellites.
• Model a wide range of signals of interest, realistic propagation and interference conditions.
• Develop and evaluate algorithms for detection, classification, parameter estimation and geolocation.
• Run large-scale simulations and translate them into operationally meaningful insights.
• Build clean, reusable APIs and tooling so that other teams can easily run scenarios.
• Integrate real mission data to validate your models.

About You

We do not expect a perfect match to every bullet point, but you should recognize yourself in most of the profile below.

Core Technical Profile

• Master's or PhD in Electrical / Communications Engineering, Aerospace Engineering, Physics, Computer Science or a related field with strong emphasis on digital signal processing and RF systems.
• Solid understanding of estimation theory, signal processing, and modern communication / signal structures.
• Practical experience building simulation frameworks for RF systems.
• Strong programming skills in Python and/or C++; experience with MATLAB or C++ is a plus.
• Comfortable with software engineering best practices: Git, testing, code review, CI/CD, documentation, and collaborative workflows.

SIGINT / Defence Domain (Strong Plus)

• Understanding of defence and security user needs.

General

• Structured, analytical working style with strong problem-solving skills and a high bar for technical quality.
• Ability to take ownership from concept through implementation to internal adoption.
• Strong communication skills: you can explain complex technical trade-offs clearly to engineers, management, and customers.
• Very good command of English (spoken and written); German is an asset.
• Eligibility for security clearance.
