Software Engineer for Quantum Networking
TypeFull-time
LocationDelft, NL
Hours40 hours
Build the software backbone of next-generation quantum networks as part of our Software Engineering team.
Overview
We are looking for a software engineer for our quantum networking device software engineering team. You'll be one of the core software engineers, with full responsibility for owning problems and independently devising solutions for specific system components. To us, that means you'll be designing, implementing, building, testing, and documenting your work, while keeping alignment with the other engineers on the team. You will be a developer with full responsibility for both extending existing sub-systems and for building whole new sub-systems.
Responsibilities
You'll be developing services in a service-oriented architecture, both between and within a distributed system of network devices. You'll be defining new communication protocols between quantum network devices, securing those protocols with cryptography, working on API design, interfacing with existing communication/routing infrastructure, and working with prototype systems. You'll probably need to learn new skills and languages (e.g., Rust). You'll work most closely with the other software engineers, and interact with the hardware team when needed.
You are passionate about advancing quantum and networking technologies and want to contribute to new ground-breaking tech. Familiarity with quantum is not required (we'll teach you that). You can work independently, are a proactive, hands-on person, and you can easily adapt to rapidly changing priorities. Above all, you're a team player and excited to work in a mixed team of hardware engineers, software engineers, and scientists.
