Keysight is at the forefront of technology innovation, delivering breakthroughs and trusted insights in electronic design, test, and measurement. Our ~16,800 employees create world-class solutions in communications, 5G, quantum, aerospace, defense, and semiconductor markets for customers in over 100 countries.
The Role
We're hiring a Senior Software Architect & Technical Lead to own the architecture of PathWave Test Sync Executive — our platform for real-time synchronization and interoperability across Keysight instruments, used in domains such as quantum computing, electronic warfare, and O-RAN test .
We're looking for someone who thinks at the system level but isn't afraid to get hands-on — an architect who can quickly grasp a complex technical vision, make it their own, and implement it with autonomy and sound engineering judgment — whether that means evolving an existing system or shaping a new one. Based in Barcelona, hybrid (minimum 2 days/week on-site).

Own the software architecture and technical vision for PathWave Test Sync Executive
Align architecture and integration strategy across multiple products and teams
Challenge requirements and propose alternatives when a better technical approach exists




Mentor and provide technical leadership to a growing R&D; team in Barcelona
Contribute hands-on to development of key features
Drive cross-team technical collaboration across a globally distributed organization (Barcelona, India, US)
What We're Looking For
Required
10+ years of software development, including 5+ years in software architecture
Strong expertise in modern C++
Experience with low-level or performance-critical systems (real-time, synchronization, hardware drivers, or embedded systems)
Deep experience working on large-scale, complex software systems — owning significant parts of the design, not just individual features
Cross-platform development (Windows and Linux)
Experience with CI/CD and modern development workflows and toolchainsStrong communication skills — able to influence across teams and levels
Preferred
Electronics engineering or hardware-adjacent academic background
Background in test & measurement instrumentation
Experience with FPGA-based systems

Based in Barcelona · World Trade Center · Parking included · Health insurance, ticket restaurant, pension plan
