About The Position

Test and Measurement Systems, also known as NI, Product R&D, is seeking a Senior RF Engineer to join our RF R&D team in Santa Rosa, CA. The role’s scope is hands-on RF/microwave hardware design and validation. You are a strategic, hands-on RF problem solver who brings initiative, sound judgment, and analytical discipline to complex engineering challenges. You will collaborate across disciplines to deliver robust, manufacturable solutions aligned to customer needs and business objectives.

Requirements

5+ years with a B.S. in EE/ECE, 3+ years with an advanced degree
Proven experience designing, simulating, verifying, and releasing RF circuits or subsystems using industry-standard tools.
Strong proficiency with RF instrumentation, including VNAs, spectrum or signal analyzers, vector generators, oscilloscopes, and related measurement equipment.
Ability to troubleshoot, simulate, and resolve RF, embedded, or mixed-signal issues at the board or system level.
Programming or scripting proficiency, with Python required and MATLAB or LabVIEW beneficial.
Excellent communication, critical thinking, and technical decision-making abilities, with demonstrated ability to lead through influence and mentor engineers appropriate to the final level.

Nice To Haves

End-to-end ownership from concept to ramp, including DFM/DFT, NPI, supplier engagement, and sustaining support.
Expertise in SI/PI for mixed-signal RF boards, grounding and shielding best practices, and robust layout for isolation and stability.
Demonstrated research and prototyping to assess emerging technologies and de-risk architectures.
Working knowledge of requirements management, risk management, project planning, and verification traceability.
Familiarity with regulatory and material compliance constraints, including EMC/safety, IEEE, MIL, RoHS/REACH, or similar requirements relevant to our markets.

Responsibilities

Viewed as a key technical resource and often the technical leader for the team, frequently advising others.
Design and execute RF/microwave hardware and subsystem work, including front ends, LO/PLL, filters, mixers, PAs/LNAs, switches, couplers, and related high-frequency circuitry to meet specifications and acceptance criteria.
Translate customer, product, and RF subsystem needs into clear specifications, acceptance criteria, design constraints, and verification approaches.
Use RF design, simulation, layout, modeling, and characterization tools to develop robust design solutions and correlate simulation results with measured performance.
Perform feasibility assessment of emerging technologies through research, prototyping, early modeling, and rapid experimentation.
Assess system‑level performance including sensing paths, signal conditioning, and inter‑device interfaces (SPI, I²C) when applicable to RF subsystems.
Develop test strategies and perform characterization using VNAs, spectrum or signal analyzers, vector generators, oscilloscopes, and automated test frameworks.
Drive assigned work through prototyping, development, V&V, compliance, NPI, and sustaining phases with minimal oversight—determining methods and procedures for new assignments.
Build strong cross functional relationships, influencing decisions through well supported technical rationale. Collaborate with Digital, Mechanical, Calibration, Software, Systems, and Test engineering disciplines, and Quality, and Operations to ensure integrated product success.
Exercise strong communication, judgment, decision-making, and critical thinking in complex technical environments.
Occasional domestic or international travel, up to 10%, to support supplier builds, customer evaluations, or factory activities.
