• Gain hands‑on experience across RF, PCB, embedded systems, FPGA, and hardware testing.
• Develop automation and control systems using Python/MATLAB and microcontrollers.
• Troubleshoot real hardware, perform RF measurements, and solve problems from root cause to solution.
• Work closely with the founding engineering team to improve performance, reliability, and manufacturability.
• Grow into a technical owner in an area that matches your strengths and interests—such as RF Filter Design, RF Systems, Embedded Systems, FPGA/Digital Hardware, or Hardware Test & Automation.

Minimum Qualifications

• Bachelor's degree in Electrical Engineering, Electrical and Computer Engineering, or a related field. An associate/two-year degree with 2+ years of relevant hands‑on experience will also be considered.
• Hands‑on laboratory experience with electrical/electronic hardware.
• Experience with MATLAB, Python, or similar engineering programming tools.
• Experience with Arduino, microcontrollers, or other hardware control platforms.
• Ability to troubleshoot hardware and perform systematic debugging.
• Strong analytical and problem‑solving skills.
• Ability to work independently while collaborating effectively with a small engineering team.
• Strong attention to detail and willingness to learn new technologies

Preferred Qualifications

• PCB design, including schematic development and PCB layout.
• High‑frequency or RF PCB design and integration.
• RF transmission lines and microwave engineering fundamentals.
• Understanding of S-parameters and RF measurements.
• Experience using vector network analyzers (VNAs) or other RF test equipment.
• RF system integration, calibration, and troubleshooting.
• FPGA development or digital hardware design.
• Magnetics, electromagnetics, or magnetic materials.
• Experience with resonators, filters, antennas, or other RF components.
• Experience with soldering, PCB assembly, rework, or other hands‑on hardware prototyping.

Why Join OneFiltr?

• Work on cutting‑edge RF technology with real-world applications in defense, communications, and aerospace.
• Learn across the stack—RF, electronics, PCB, embedded systems, FPGA, and hardware testing.
• Work directly with experienced engineers and researchers in a fast-moving startup environment.
• Own real engineering problems and see your work go from prototype to product.
• Build your career with us: grow from hands‑on hardware development into a technical owner in RF Filter Design, RF Systems, Embedded Systems, FPGA/Digital Hardware, or Hardware Test & Automation.
• Competitive compensation + equity, with paid time off, paid holidays, and benefits from day one.
