Electrical Engineering Technician

OneFiltr is developing next-generation tunable RF filters for defense, satellite communications, wireless infrastructure, and advanced RF systems. We are looking for an entry-level Electrical Engineer who enjoys hands-on hardware development and wants to work closely with RF systems, electronics, testing, and product development.

What You'll Do

• Build and test next-generation tunable RF hardware from prototype to product.
• 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.
