Technical Support Specialist - LED Lighting Controls (DMX/Pixel) - Argentina Rem

We're Green LED Lighting Solutions, a Canadian LED manufacturer. Our systems go into buildings, signs and entertainment venues across North America, and when an installer is on a job site with a controller that won't talk to the pixels, they call us. We need one more person on that phone.

SHIFT: North American business hours, 9:00 AM to 6:00 PM Eastern (10:00 AM to 7:00 PM Buenos Aires). Fixed schedule, Monday to Friday. Remote, contract.

WHAT YOU'LL DO

• Take technical support calls and emails from North American electricians and installers during our support window. Diagnose live: pixel data problems, DMX addressing, voltage drop, controller setup, warranty issues.

• Write the fix down so the same call doesn't come back. Knowledge base articles, checklists, short videos.

• Between calls, produce wiring diagrams and fixture layouts in AutoCAD from our design lead's markups, and build the costed bill of materials that goes with them.

NOT A FIT IF

• You want a drafting or estimating job with a few calls. This is a phone job with design packages in the gaps.

• You get rattled by a frustrated caller.

• You need a script.

TO APPLY

Put the word PIXEL in the first line of your cover letter. Then attach: (1) a link to a 2-minute video of you explaining voltage drop on a 12V LED run to an electrician who's never heard the term, (2) one wiring diagram or schematic you drew yourself. Applications without both won't be reviewed.

Requirements

• 2+ years in technical support, field service or commissioning for LED lighting, lighting controls, AV or similar low-voltage electronics

• Working knowledge of DMX512 addressing and topology, SPI pixel basics, and low-voltage DC power (voltage drop, power injection, PSU sizing). We'll test this.

• AutoCAD, well enough to turn a markup into a clean electrical schematic

• Spoken English you can run a troubleshooting call with. Our callers are electricians on job sites, on bad connections, behind schedule. You'll do a live phone screen.

• Daily use of AI tools in your work. Show us how, don't tell us.

• Full availability for the fixed shift (10:00 AM to 7:00 PM Buenos Aires, Monday to Friday)

Nice to have: hands-on time with Advatek, Falcon, PixLite, ENTTEC, Pharos or Madrix; experience with RMA or warranty processes; Elfsquad, Business Central or a similar CPQ/ERP.
