(Senior) Software Engineer (all genders) - The Glue Code

We build award-winning smart glasses in Vienna: hardware, firmware, software, all under one roof. Our SDI team (Sensors, Data & Intelligence) does extraordinary work, cognitive models, signal processing, machine learning, but brilliant algorithms need brilliant software infrastructure to ship. We're looking for a senior engineer who can speak both languages: clean, production-grade C and Rust on one side, and the complex world of cognitive and sensor data on the other., * Build and maintain the software architecture that connects the SDI team's algorithms to the broader product, and work closely with the Software team lead to design and implement architectures that integrate new and existing algorithms into deliverable products

• Develop and maintain the interfaces between SDI and other engineering teams, because good interfaces don't happen by accident
• Own and continuously improve the build systems, infrastructure, and CI/CD pipelines, raising the bar to automatic testing & delivery
• Take initiative to restructure and clarify existing code: you see messy systems and want to fix them and do, not work around them
• Understand what the SDI algorithms do and make smart architectural decisions, you don't need to be the data scientist, but you need to get it
• Know how to test things properly, including quantitatively and in real-time data processing contexts

• Fluency in C and Rust, not just familiarity, but genuinely comfortable in both
• Strong software engineering fundamentals: architecture, clean code, modularity, and maintainability
• Experience with CI/CD pipelines, build systems, development infrastructure, and testing frameworks
• Ability to work at the intersection of research and engineering, translating complex algorithmic work into robust software systems
• A natural drive to bring clarity and structure to ambiguous codebases
• Collaborative by nature: you work well with researchers, engineers, and team leads
• Fluent English; German is welcome

Nice to have

• Familiarity with signal processing, ML pipelines, sensor data, or measurement software environments
• Experience in a deep-tech, hardware-adjacent, or embedded software environment
• Background working in cross-functional teams spanning research and product

What's extra?

• Salary: €3.954 - €5.500 gross/month depending on experience
• Yearly public transport card (Vienna)
• Workation within the EEA
• Dog-friendly offices
• "Inspire Days" - time to learn and recharge
• A front-row seat to how a deep-tech hardware product gets built, from PCB to shipped device
• Small, international team where your impact is visible every day
