Design and implement RF/microwave components, including power amplifiers, combiners, filters, directional couplers, and custom packaging solutions.
Prototype, characterize, and validate hardware using instruments such as VNAs, spectrum analyzers, and load-pull setups.
Collaborate with embedded, mechanical, and system engineers on system-level integration.
Contribute to antenna system design and performance evaluation for heating and field strength control.
Develop and maintain automated measurement setups using Python.
Work with manufacturing teams on design for manufacturability, test procedures, and performance tuning.
Participate in customer-driven product development cycles, refining designs to meet application-specific needs.
Support patent drafting and engage in technical publications or conference contributions, if aligned with project goals.

Minimum Qualifications

Master’s or PhD in Electrical Engineering, Engineering Physics, or equivalent with focus on RF/microwave engineering or electromagnetics.
3+ years of research or industry experience in RF/microwave circuit design.
Proven skills in modeling and simulation tools: ADS, HFSS, CST, AWR, or similar.
Experience working with RF measurement equipment: VNAs, signal generators, spectrum analyzers.
Strong initiative, analytical mindset, and problem-solving drive.
Fluent in English (written and spoken). Swedish is a plus.

Preferred Skills & Experience

Experience designing both linear and nonlinear RF blocks: power amplifiers, mixers, frequency multipliers, filters, and PLLs.
Deep understanding of microwave passive components, transmission lines, and RF layout.
Experience with antenna design, field uniformity control, and electromagnetic field simulations.
Proficiency in Altium, KiCad or equivalent PCB layout tools.
Familiarity with Python, Matlab for RF system modeling and measurement automation.
Demonstrated ability to work across domains bridging analog hardware with digital control and embedded systems.
Exposure to industrial heating applications, thermal-microwave interaction, or microwave safety compliance is a bonus.
Track record in IP generation and/or entrepreneurial projects is highly valued.

Why Join Us?

At Percy Roc, you’ll shape a new industrial paradigm at the intersection of RF engineering, clean tech, and systems innovation. You will have the opportunity to:

Work at the forefront of industrial electrification using microwave technology.
Build unique IP and contribute to patentable innovations.
Influence the company’s technical direction and system architecture.
Grow with a highly collaborative team, blending scientific rigor with industrial execution.
