About Epirus

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. Learn more about the ITAR here.  

People are the most important part of Epirus – and always come first. We don't believe in the word impossible and are always asking "why not" as work to usher in a new paradigm of power efficiency. Our fast-growing team is agile, creative, and innovative. We support a culture of constant learning and sense of belonging among our team members and know that mentorship matters. We embrace diversity, equity and inclusion in the workplace and beyond. To deliver on our mission, we are always looking for problem solvers, changemakers and innovators to join our fast-growing team.

As required by the Equal Pay Transparency Act, Epirus provides a reasonable range of minimum compensation for roles that may be hired. Actual compensation is influenced by a wide array of factors including but not limited to skill set, level of experience, and specific office location.

For the state of California only, the range of starting pay for this role is:

$36—$38 USD
