Overview
WISeSat AG is developing a Low Earth Orbit (LEO) constellation to deliver secure messaging services across Switzerland and Europe, leveraging proprietary post-quantum encryption. We work with selected industry partners to deliver an end-to-end system.
Role Overview: You will own the system view across satellite, ground and user equipment. Your mission is to translate objectives into clear technical requirements, coordinate delivery with internal teams and partners, and ensure the system is coherent, testable, and ready for operations.
Key Responsibilities
* Define and maintain the end-to-end system architecture and technical roadmap.
* Translate business and service objectives into requirements for internal teams and external partners.
* Establish and manage interfaces (ICDs) so components integrate correctly.
* Plan and oversee design reviews, integration, and validation; confirm performance against targets.
* Monitor schedule, risks, and quality; drive resolutions and trade-offs when needed.
* Coordinate with partners on deliverables and acceptance criteria; track progress against milestones.
* Support spectrum and regulatory activities and ensure alignment with relevant standards.
* Prepare for operations: concepts of operations, procedures, and handover to the ops team.
* Embed security-by-design, including integration of post-quantum cryptography.
Qualifications
* 6–10 years in space or telecom systems engineering, ideally with multi-party delivery.
* Solid understanding of satellite communications fundamentals (link budgets, Doppler, interference) and ground network basics.
* Proven experience with requirements management, interface control, and system verification/validation.
* Comfortable coordinating industry partners/suppliers and leading technical discussions and reviews.
* Structured, analytical, and decisive; strong written and verbal communication.
* Degree in Engineering (Systems, RF/Telecom, Electrical, or similar).
* English required; French a plus.
Why WISeSat
* High ownership and direct impact on a real service.
* Close collaboration with experienced partners and a focused internal team.
* Competitive package; hybrid work possible in Geneva.
