RF Engineering Intern

Epirus is a high-growth technology company developing software-defined high-power microwave (HPM) systems with devastating counter-electronics effects on modern drone threats. The Epirus Leonidas HPM family of products, empowered by innovations in AI and microelectronics, is human-safe and cost-effective. Distinguishing itself from lasers, Leonidas excels against drone swarms while also bending the cost curve back in DoD's favor - taking drone defeat costs from millions of dollars per drone to pennies on the dollar. 

Job Summary: This is an exciting role in a growing company. We are looking for interns to join us on a 10-week internship program. This will be a hands on and in-person position.  

 Are you fascinated by the invisible forces that connect the world? Join our RF Engineering team and dive into the cutting edge of counter-electronics technology. As an RF Engineering Intern, you’ll be part of a fast-paced, innovation-driven environment where you'll contribute to real hardware projects that impact next-generation systems. 

This is more than an internship – it's a launchpad into the world of antennas, RF power amplifiers, and early-stage product design. If you're excited by electromagnetic waves, RF circuits, and challenging problems, we want to hear from you. 

What You'll Do 

•  Design, test, and optimize antennas for novel wireless applications 

• Assist in the development and characterization of RF power amplifiers, including simulation, layout, lab testing, and performance analysis 

• Conduct feasibility studies on new product concepts – exploring real-world constraints like form factor, thermal performance, and in-field deployability 

• Support lab experiments and measurements using spectrum analyzers, VNAs, signal generators, and custom RF setups. 

• Analyze RF performance metrics (Active S-parameters, X-parameters, PAE, EVM, etc.) and help translate them into design recommendations. 

• Collaborate with senior RF engineers, cross-disciplinary functions, and product managers to bring ideas from whiteboard to prototype. 

Why You'll Love It Here 

• Work on real RF hardware from day one  

• Be part of a tight-knit, curious team that thrives on experimentation and big ideas 

• Gain exposure to product development from concept to prototype 

• Access to a fully equipped RF lab and mentorship from seasoned engineers 

• Opportunity to contribute to innovative products in commercial & defense applications 

• Pursuing a Bachelors degree in Electrical Engineering, Electronics Engineering, or any related field 

• Rising senior or beyond at time of internship and have a graduation date between 12/2026 - 12/2027. All applicants should be returning to school at the end of their internship to continue their academic studies. 

• Prior internship, collegiate project team, or laboratory experience 

• Experience with RF hardware design (antenna design, microwave power amplifier design) and test equipment (VNA, power analyzer, signal generator, waveform generator) 

• Experience with RF design tools (Keysight ADS, Ansys HFSS, CST, AWR) 

• Python Experience 

• U.S. Person status is required as this position needs to access export-controlled data 

ITAR REQUIREMENTS:  

• To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
