Your responsibilities

• Lead development of core features of LabOne Q, encompassing concept, implementation, testing, and documentation.
• Contribute to software architecture evolution by questioning existing interfaces, discovering optimal abstractions, and establishing clean domain boundaries.
• Identify and resolve performance bottlenecks through systematic profiling, algorithmic improvements, and architectural refinements.
• Design stable, extensible external interfaces for system integrators and research applications.
• Ensure efficient integration with lower-level software, firmware, and gateware components.
• Collaborate effectively with peers in R&D and product management on architecture, interfaces, and feature breakdown.
• Debug complex problems across the whole stack and implement effective solutions.

Your profile

• MSc or PhD in Computer Science, or in Physics/Electrical Engineering with a strong complementary software background.
• Professional track record of 5+ years in writing production-grade, maintainable code in Python and Rust, or deep expertise in C++ or similar systems programming languages.
• Proven experience with software architecture, algorithms, and data structures. Knowledge of compiler architecture and construction is highly valued.
• Desire to develop into an expert in quantum computing control software stacks. Knowledge of digital signal processing and experience with lab equipment or hardware is a plus.
• Excellent communication skills and stakeholder management, both internally and externally.
• Strong problem-solving, troubleshooting, and analysis skills.
• Team player who enjoys close collaboration with other team members.
• Fluent in English; additional languages are a plus.
