CX2 is a next-generation defense technology company founded to deliver spectrum dominance for the United States and our allies. CX2’s AI-enabled hardware and software platforms detect, disrupt and defend the electromagnetic spectrum across land, air, sea and space domains.
We are seeking an experienced Engineering Specialist (Drone & RF Electronics Assembly) to join our team! This position supports the Engineering team by assembling, integrating, tuning, and reworking drone electronics and RF subassemblies (not wiring harness fabrication). This role focuses on high-quality prototype and pre-production builds, RF/mechanical integration, and fast iteration feedback to engineering.
Key Responsibilities
· Assemble and integrate drone electronic modules: RF boards/modules, compute, power distribution, telemetry/radios, antennas, GNSS modules, sensors, and payload electronics.
· Perform PCB-level assembly and rework as needed (SMT touch-up, connector replacement, fine-pitch soldering, component swaps) using microscope and ESD controls.
· Execute RF integration tasks:
- Install and secure antennas, RF modules, coax interconnects, and RF shielding/absorbers.
- Support RF checkouts (e.g., basic link check, frequency/power verification per procedure).
- Identify and communicate RF-related build issues (connector stack-ups, shielding gaps, placement/coupling concerns).
· Perform electro-mechanical integration in airframes: mounting, alignment, vibration mitigation, thermal interface materials, staking/adhesives, fastener torqueing, and connector mating.
· Support prototype iteration and debug: controlled rework, ECO changes, swaps, and build experiments; keep clean “as-built” notes.
· Conduct basic bring-up and acceptance checks per instructions (power-on, current draw sanity, comms/link verification, sensor detection, basic functional checks).
· Maintain build documentation and traceability: serial numbers, firmware/config versions when required, build travelers, and deviation/NCR notes.
· Improve build readiness: create/update work instructions/checklists, suggest fixture needs, improve kitting and bench organization.

Required Qualifications

  • Minimum years hands-on experience assembling electronics, preferable drones/robotics/RF systems or similarly fast-iterating hardware
  • Strong ESD discipline and comfort working with delicate components and small fasteners
  • Ability to interpret assembly drawings, BOMs, schematics, and controlled build instructions
  • Practical soldering and rework skills; comfortable with microscopes and precision tools
  • Strong documentation habits and clear communication of build issues
  • NOTE: Local candidates only; this position does not offer relocation

ITAR Regulations

  • To conform to U.S. Government export regulations, applicant must be a US Citizen, Green Card holder, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.

Bonus Points

  • Experience with RF hardware and interconnects (e.g., SMA/u.FL/MMCX, coax routing/strain relief, shielding cans/tape/gaskets).
  • Familiarity with basic RF test equipment and workflows (spectrum analyzer, power meter, VNA) at a support level.
  • Experience with vibration/thermal considerations in airframes (thread-lock, staking, thermal pads/paste).
  • IPC exposure/certification (helpful but not always required in prototype teams).

What We Offer

  • Competitive salary, stock options and benefits, including health, vision and dental.
  • 401K enrollment at 90 days.
  • Generous PTO + most Federal Holidays observed.
  • Professional growth and development opportunities.
  • Collaborative and inclusive work environment.
  • High levels of responsibility and autonomy.
  • Access to the latest tools and technologies as well as the hardest problems in electronic warfare.
