R&D Software Engineer 

Job Description:

We are looking for an experienced R&D Software Engineer to join the High Frequency Measurements (HFM) team. The role focuses on the design and development of advanced software solutions for state-of-the-art RF test and measurement instruments, specifically Vector Network Analyzers, used for high-performance RF and microwave measurements.

In this role, you will contribute across the complete product lifecycle—from requirements definition and architecture to development, validation, and post release support. You will work closely with RF, hardware, firmware, and system engineers to deliver accurate, reliable, and high-performance measurement solutions.

Key responsibilities include:

• Designing, developing, testing, and maintaining complex software components for VNA based RF measurement systems.
• Developing software that controls and interfaces with RF instrumentation, measurement hardware, and embedded systems.
• Implementing algorithms related to RF measurements, signal processing, calibration, correction, and data analysis for VNAs.
• Working on system level software that integrates RF frontend hardware, firmware, and user facing applications.
• Debugging and resolving complex customer, system, and application-level issues involving both software and hardware interactions.
• Documenting software designs, architectures, algorithms, and implementation details.
• Collaborating with cross functional teams to transition new designs and enhancements into production.
• Contributing to feature definition, design reviews, and technical decision-making for complex subsystems.
• Staying current with industry trends in RF, microwave measurements, and modern software technologies, and applying them to product development.

Essential Qualifications:

• Bachelor’s or Master’s degree in Electronics Engineering, Electrical Engineering, Instrumentation Engineering, or equivalent, with strong software development expertise.
• 6+ years of R&D experience in product or system level software development.
• Strong experience developing large, production quality software applications.
• Proficiency in C++ (Modern C++ preferred) and object-oriented design.
• Solid understanding of software design principles, data structures, and algorithms.
• Experience with hardware–software integration, especially in test and measurement systems.
• Good knowledge of RF and electronics concepts.
• Strong problem-solving skills with the ability to work on complex, high impact issues.
• Excellent written and verbal communication skills.
• Self-driven, adaptable, and capable of quickly learning new technologies and domains.
• Strong team player with a high level of ownership and accountability

Preferred Qualifications / Nice to Have:

• Experience working with Vector Network Analyzers (VNA) or RF/microwave test and measurement instruments.
• Background in RF and microwave measurements, including S-parameters, calibration techniques, and error correction.
• Good understanding of RF and electronics fundamentals.
• Experience with MFC for Windows based application development.
• Familiarity with Visual Studio development environment.
• Experience with Atlassian tools such as Git, Jira, and Confluence.
• Exposure to Agile / Scrum software development processes.
• Experience with instrument control, measurement automation, or precision measurement systems.

Why Join Us

You will be part of a highly skilled R&D team working on industry leading VNA and RF measurement solutions, solving challenging problems at the intersection of software, RF, and electronics, and directly impacting next generation test and measurement products.
