Mechatronics Engineering Intern

ABOUT ELDAEON

ELDAEON is building the world's first tactical UAP-detection network. Our sensor-fusion platform is engineered ground-up to detect what conventional defense systems were never designed to see — anomalous aerial phenomena that violate restricted airspace, including near nuclear facilities and military installations. Our platform is:

• Modular — adaptable across rooftop, field, and networked regional deployments
• Multimodal — fusing optical, RF, environmental, biometric, and temporal data
• Real-time — live detection, correlation, and characterization of aerial phenomena

We are sensor hackers, reverse engineers, and deep-tech builders. We build what others won't.

THE ROLE

You'll join our hardware team as a Mechatronics Engineering Intern for a 8 week, Summer 2026 internship (immediate start preferred, opportunity to convert full-time), working across our two flagship sensing platforms:

DIONYSUS — our multi-sensor UAP-detection enclosure. Integrates RF (HackRF, RTL-SDR, PlutoSDR), compute (Raspberry Pi stacks, Jetson Orin Nano, NucBox mini-PC), particle detection (PicoMuon cosmic-ray, Geiger counter), EMF, GPS, and electro-optical cameras inside a weatherproof, field-deployable chassis with active ventilation.

NEMESIS — our passive radar system. Servo-actuated RF antenna array driven by software-defined radio, antenna control board (ACB), and Raspberry Pi compute.

This is a hands-on role across CAD, electromechanical integration, thermal/ventilation design, PCB bring-up, soldering, 3D printing of custom mounts, and bring-up of new sensor payloads. You will own real subsystems shipping to early customers.

WHAT YOU'LL DO

• Design and 3D print mechanical enclosures, brackets, and modular bays in CAD (Fusion 360) for DIONYSUS and NEMESIS subsystems
• Integrate embedded compute (Raspberry Pi, Jetson Orin) with RF front-ends (SDRs, antennas, ACB) and electro-optical cameras
• Design, fabricate, and bring up custom PCBs — schematic capture, board layout, hand-soldering, debug
• Build out servo and actuator control for NEMESIS antenna positioning (PWM, encoders, closed-loop control)
• Design thermal-management and IP-rated ventilation solutions for outdoor-deployable hardware
• Wire and bring up new sensor payloads — RF, EO, environmental, particle
• Contribute to BOMs, assembly procedures, and field-deployment runbooks
• Work directly with founders and senior engineers on weekly hardware reviews

WHAT WE'RE LOOKING FOR

Required:

• Completed BS or MS in Mechatronics, Mechanical, Electrical, Aerospace, Robotics, or a related engineering discipline (degree already conferred, current students are not eligible)
• Proficient in at least one CAD tool (Fusion 360, SolidWorks, or Onshape)
• Hands-on experience with at least one embedded platform — Raspberry Pi, Arduino, Jetson, STM32, or similar
• Comfortable with hand-soldering through-hole and surface-mount components
• Able to be on-site in Azusa for the full internship
• 3D printing fluency (FDM/SLA) for functional parts — not just hobby prints
• Agentic Programming w/Loops (Claude Desktop / Claude CLI)

Strongly preferred (any combination):

• PCB design experience (KiCad, Altium, or similar) — schematic + layout
• Software-defined radio (HackRF, RTL-SDR, PlutoSDR, GNU Radio)
• FPGA development (Verilog/VHDL, Vivado/Quartus) — Zynq, Artix, or similar
• Servo / motor control with encoders and closed-loop tuning
• Electro-optical camera integration (machine-vision cameras, lens selection, image pipelines)
• Linux command line and Python
• Thermal management and IP-rated enclosure design

Bonus:

• Personal projects in robotics, drones, ham radio, astronomy, or sensor-fusion
• Genuine curiosity about UAP, anomalous aerial phenomena and the frontier of sensing

PERKS

• Paid — $20/hr, full-time (40 hrs/week)
• Free company-provided housing in Azusa, CA available for select interns (decided at offer stage; based on candidate strength and need)
• Real ownership — you ship subsystems to early customers, not throwaway intern projects
• Direct access to founders and senior engineers
• Frontier work — the platform you'll build doesn't have a textbook

ITAR / EXPORT CONTROL NOTICE

ELDAEON develops technology subject to U.S. export-control regulations, including the International Traffic in Arms Regulations (ITAR) administered by the U.S. Department of State's Directorate of Defense Trade Controls (DDTC). Radar-related work is restricted to U.S. Persons. Core radar signal processing, NEMESIS passive-radar firmware, and any related controlled technical data may only be accessed by U.S. Persons as defined under 22 CFR §120.62 (U.S. citizens, U.S. lawful permanent residents, and protected individuals under 8 U.S.C. §1324b(a)(3)). Non-U.S. Persons remain eligible for this role and may work on ancillary, non-controlled scope including general mechanical design, enclosures, thermal/ventilation, non-radar sensor integration (EO, environmental), 3D printing, and supporting infrastructure. Final scope assignment is made at offer stage based on applicant status and current export-control posture. We evaluate every qualified applicant on the merits and structure scope around compliance — citizenship is not a disqualifier for the role itself.
