Senior Software Architect & Technical Lead – Instrument Synchronization (C++)

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).

What You'll Do

• 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)
• Strong API design skills
• Experience with CI/CD and modern development workflows and toolchains
• Strong 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
• Experience with Python, C#, or setting up CI/CD pipelines from scratch
