Electronics Technician

9-mothers; Austin (TX); On-site; USD 55,000 - 82,000; Full time

Job summary

9 Mothers is seeking an Electronics Technician to own hands-on fabrication of cables, harnesses, and PCBAs for drone-counter hardware. You will build end-to-end wiring, verify continuity, and document builds for repeatability.

The role involves field support at test ranges and occasional travel, with work on rugged, military-grade platforms. You must read schematics, select proper connectors, and demonstrate meticulous workmanship and tracking of as-builts and test records.

Qualifications

• 5+ years of hands-on experience as an electronics technician or similar role building and repairing complex electromechanical hardware.
• Expert-level cable and harness fabrication, including crimping, soldering, pinning, and strain relief.
• Proficient reading of schematics, wiring diagrams, and harness drawings.
• Experience with DMM, oscilloscope, and power supplies for troubleshooting.
• Meticulous workmanship and documentation habits (as-builts, redlines, test records).

Responsibilities

• Build cables and wire harnesses from schematics or engineer sketches, using proper tools.
• Work across connector families including circular, mil-spec, D-subs, and RF/coax connectors.
• Label, sleeve, and strain-relieve harnesses for rugged outdoor/live-fire platforms.
• Verify builds and capture as-builts and redlines to speed future builds.
• Wire compute and control enclosures end-to-end; perform power-up checks.
• Do PCBAs rework and repair, including SMT component replacement.
• Set up simple electrical test rigs and log results for engineering action.
• Travel to test ranges for field support and live-fire events, per requirements.

About 9 Mothers

The modern battlefield has changed. Cheap, autonomous suicide drones have turned the tactical advantage upside down, and the world is looking for a solution. At 9 Mothers, we aren't just "innovating"-we are building the shield. Backed by top-tier investors, we develop AI powered machines designed to intercept and neutralize Group 1/sUAS threats in real-time. Our flagship product is a low-power, counter-drone system built for the edge-on vehicles, at bases, or in a soldier's pack.

Why 9 Mothers?

While others build for "awareness" or "long-term research," we build for the immediate survival of those in harm's way. We are a team of hackers, engineers, and mission-driven builders who value field-ready capability over polished slide decks. If you want to see your code or hardware in the field next month-not next year-this is your playground.

Position Summary

9 Mothers builds robotic weapons systems - including EDDA, a robotic shotgun turret for counter-UAS, and a proprietary belt-fed shotgun platform. Every prototype we field is an electromechanical system full of cable harnesses, wired compute and control boxes, and custom PCBAs. Today, that build work is done by mechanical engineers and engineering management. That stops with this hire.
This role owns hands-on electronics fabrication for the company: building cables and harnesses, wiring compute and control enclosures, and reworking PCBAs. Your workmanship goes directly into weapons systems that get run hard at the range, so it has to be right - clean, documented, and durable. Most of your time is in the Cable & Harness Fabrication (Core)

Build cables and harnesses

• Build cables and wire harnesses from schematics, harness drawings, or an engineer's sketch - cut, strip, crimp, solder, pin, and pot as required

Work across connector families

• Work across connector families common to robotic and vehicle systems: circular/mil-spec connectors, D-subs, Molex/JST/board-level connectors, RF/coax, and power connectors, using correct tooling for each

Labeling and harness protection

• Label, sleeve, and strain-relieve harnesses for hard use on outdoor, live-fire robotic platforms - vibration, heat, dust, and repeated teardown

Verification

• Verify every build: continuity, pinout, insulation resistance / hipot where appropriate; capture as-builts and redline drawings so the next build is faster

Box Builds & System Wiring

• Wire compute and control enclosures end-to-end: panel layout, component mounting, power distribution, wire routing and dressing, grounding and shielding


• Perform point-to-point checkout and initial power-up checks before handing boxes to engineering for bring-up


• Build repeatably - when we need the second and third unit, they should match the first

PCBA Rework & Repair

• Rework and repair PCBAs: component replacement (through-hole and SMT), ECO / blue-wire modifications, connector replacement, and conformal coating touch-up


• Troubleshoot boards and assemblies to the failed component using DMM, oscilloscope, and bench power supplies

Test Setups & Fixtures

• Build and run simple electrical test setups: cable life/flex testing, actuator test fixtures, breakout boxes, load banks, and long-duration soak tests


• Instrument tests, log results, and report failures with enough detail that engineering can act on them


• Maintain the electronics lab: test equipment, soldering stations, crimp tooling, and stock of wire, connectors, and consumables

Field Support

• Travel to test ranges when needed to repair harnesses, boxes, and electronics on deployed systems and support live-fire test events


• Work safely around firearms and an active belt-fed shotgun platform, with disciplined adherence to range safety protocols

Requirements

• 5+ years of hands-on experience as an electronics technician, electrical assembler, or similar role building and repairing complex electromechanical hardware - robotics, aerospace, defense, automotive, test equipment, or industrial systems


• Expert-level cable and harness fabrication: crimping, soldering, pinning, and the judgment to pick the right connector, wire gauge, and strain relief for the application


• Proficient soldering and rework skills, including SMT component replacement


• Able to read and work from schematics, wiring diagrams, and harness drawings - and to build sensibly from an engineer's verbal description or sketch when a drawing doesn\'t exist yet


• Competent with standard bench equipment: DMM, oscilloscope, power supplies; able to trace electrical faults methodically


• Meticulous workmanship and documentation habits: labeling, as-builts, redlines, test records


• Comfortable working around firearms and live-fire operations, and willing to travel occasionally to test ranges in central Texas conditions (heat, dust, outdoor work)


• US person (citizen or lawful permanent resident) - required for ITAR compliance

Nice-to-Have

• IPC/WHMA-A-620 (cable and harness), IPC-A-610, or J-STD-001 certification - or demonstrably equivalent
