Hybrid Electronics Engineer – Quantum Communication, Space Systems

at Quantum Technologies GmbH

• Job title: Electronics Engineer – Quantum Communication, Space Systems
• Job type: Full Time
• Experience level: Junior
• Salary: €3,500 per month
• Degree requirement: Bachelor's Degree
• Location requirements: Hybrid, Wien, Austria

About the role

• Electronics Engineer designing high-performance electronics for quantum key distribution systems. In a hands-on hybrid role, collaborate with interdisciplinary teams in quantum communication and space systems.

Responsibilities

• Own end-to-end hardware development: from system architecture down to board-level implementation and lab validation.
• Design and implement high-throughput data acquisition and signal-processing electronics, including analog front-ends, timing, and high-speed digital interfaces.
• Develop and optimize PCB layouts for performance, manufacturability, EMC, and reliability; drive DFM/DFT improvements with suppliers.
• Build rapid prototypes and test fixtures to validate requirements and de-risk concepts; plan and execute bring-up, characterization and verification.
• Select and qualify space-grade components; plan and lead part qualification campaigns with vendors and labs.
• Collaborate closely with optical, FPGA, and software engineers to define clear system requirements and interfaces.
• Perform detailed analyses (parts-stress, worst-case, FMEA/FMECA) under radiation, thermal, vibration, and EMC constraints.
• Design noise-free analog power supplies and FPGA environments for high-speed, low-noise operation.

Requirements

• Hands-on experience in PCB design/layout, including stack-up definition, impedance control, length matching, and EMI/EMC design.
• Strong lab skills: oscilloscopes, VNAs, spectrum analyzers, and root-cause analysis.
• Solid understanding of high-speed DAQ architectures, synchronization, clocking, and data movers to FPGAs or SoCs.
• Familiarity with space electronics reliability (radiation effects, derating, thermal design) and ECSS/MIL standards.
• Experience with power integrity and analog design for mixed-signal systems.
• Clear and confident technical communication in English (specifications, test plans, design reviews).
• A collaborative mindset and ownership attitude; comfortable iterating quickly in an interdisciplinary environment.

Benefits

• A mission-driven environment developing quantum-secure communication for the space era.
• Close collaboration with leading researchers and engineers in quantum optics, FPGA, and embedded systems.
• Hands-on involvement in all phases - from prototype to flight model.
• Flat hierarchies, ownership, and the opportunity to drive innovation in an emerging deep-tech sector.
• A collaborative and innovative environment in Vienna, a global hub for quantum research and space technology.
• Flexible work arrangements in a hybrid model combining remote and onsite collaboration.
• Balanced work-life integration for our employees.
• Attractive workplace with excellent infrastructure at Wienerberg.
• Great Italian espresso.
• Humorous and friendly work atmosphere.
