San Antonio’s low-voltage market doesn’t get talked about the way Dallas or Houston do, but the work is out there — data centers going up along Loop 1604, hospital expansions on the Medical Center side of town, security and access-control retrofits across downtown high-rises. The technicians who land the good jobs aren’t necessarily the most experienced ones. They’re the ones who show up with the right paperwork, apply in the right places, and know how to talk about their skills in a way a hiring manager can actually use.
Here’s what that looks like in practice.
Start with what “low voltage” actually covers
Employers in San Antonio use “low-voltage technician” as an umbrella term for several different specialties, and knowing which one you’re pitching yourself for matters. Structured cabling and data/voice work (running and terminating Cat6/Cat6a, fiber) is its own lane. So is security and access control — cameras, card readers, alarm panels. Fire alarm systems are regulated separately and need their own state license. AV integration is closer to IT than electrical work these days. If your resume just says “low voltage” with no specifics, you’re competing with everyone. If it says “structured cabling, BICSI-trained, comfortable in a data closet,” you’re competing with far fewer people for a role that pays better.
Get the certifications that actually move the needle
You don’t need a four-year degree for this trade, but you do need proof you can be trusted around a customer’s building and their equipment. The ones that matter most in Texas:
- NCCER Electrical/Low Voltage credentials. These are the industry-standard, portable “green card” certifications most staffing agencies and contractors ask for first. If you haven’t gone through an NCCER-accredited program, it’s worth the time.
- BICSI Installer 1 or Installer 2 for anyone doing structured cabling. Installer 2 splits into copper (INSTC) and fiber (INSTF) tracks — pick based on what kind of jobs you want.
- OSHA 10 or OSHA 30. Almost every commercial job site in San Antonio requires one of these before you can badge in.
- A clean background check and drug screening history. Most low-voltage work happens in occupied buildings — hospitals, schools, office towers — and clients run background checks on every technician who sets foot on site, not just the company that employs them.
None of these take more than a few weeks to knock out, and having them ready before you apply, rather than promising to get them “if hired,” puts you ahead of most of the applicant pool.
Where the actual openings are
San Antonio’s low-voltage jobs come from three directions, and each one is worth checking separately:
- Specialty contractors — the electrical and security integration firms that bid directly on commercial and institutional projects. These are often the best-paying jobs but the hardest to find, since a lot of them don’t post publicly until they’re already behind on a project.
- General staffing agencies with a skilled-trades desk. Big national firms place some low-voltage roles, but San Antonio isn’t usually their focus market, so openings can sit unfilled for weeks.
- Regional staffing specialists who work specifically in electrical, low-voltage, and fire-alarm placement across Texas. This is where a lot of the fastest-moving openings land, because these firms already have relationships with the contractors doing the hiring and can move you into a role in days instead of weeks.
Flex Tech works this third lane specifically. If you’re a licensed or NCCER-certified low-voltage technician in the San Antonio area, our recruiters typically know about openings before they’re posted anywhere public, and can walk you through what a specific contractor is looking for before you ever submit an application.
Pay expectations, so you’re not guessing
Statewide, low-voltage technicians in Texas average around $47,375 a year, or roughly $22.78 an hour, with the middle half of the market landing between about $38,700 and $52,600 annually, according to ZipRecruiter’s August 2026 data. San Antonio rates run close to that statewide number — a little softer than Dallas or Austin for entry-level roles, but contract and contract-to-hire positions on data center or hospital projects often pay above the statewide average, especially for anyone with structured cabling or fire-alarm crossover experience.
Contract-to-hire vs. direct hire: know which one you’re walking into
A lot of San Antonio low-voltage work is staffed contract-to-hire, meaning you start as a placed contractor and convert to the client’s payroll after 60 to 90 days if it’s a fit on both sides. This isn’t a red flag — it’s how most commercial contractors staff up for a project without over-committing before they’ve seen your work. What matters is asking upfront: what’s the conversion timeline, what’s the pay rate during the contract period versus after conversion, and who handles benefits during the contract phase. A staffing agency that can’t answer those questions clearly isn’t one you want representing you.
The application itself
Skip the generic resume upload if you can. Call or email a recruiter who works this specific trade, describe exactly what you’re certified in and what kind of sites you’ve worked, and ask what’s open right now. Low-voltage hiring in San Antonio moves fast when a project is behind schedule, and the technicians who get placed are usually the ones a recruiter can vouch for personally, not the ones sitting in a resume database.

FAQ
Do I need a state license to work as a low-voltage technician in Texas?
Not for most structured cabling, security, or AV work — those aren’t state-licensed trades in Texas. Fire alarm work is the exception; it requires a license from the State Fire Marshal’s Office. Electrical work tied to line-voltage wiring generally requires TDLR electrician licensing.
What’s the fastest way to get hired if I’m new to the trade?
An NCCER Electrical/Low Voltage credential plus OSHA 10 gets you past most first-round screening. From there, working with a staffing agency that places entry-level techs on contract-to-hire projects is usually faster than applying directly to contractors, who often only hire experienced techs off the street.
How much do low-voltage technicians make in San Antonio?
Statewide average is about $47,375 a year ($22.78/hour), with the middle of the market between roughly $38,700 and $52,600. San Antonio tracks close to that statewide figure, with contract roles on larger commercial projects often paying above it.
Is contract-to-hire a bad sign?
No — it’s the standard staffing model for most commercial low-voltage work in Texas. Ask about the conversion timeline and pay structure before accepting, and work with a recruiter who can explain both clearly.
What certifications should I get first?
NCCER Electrical/Low Voltage and OSHA 10 first. Add BICSI Installer 1 or 2 if you want to specialize in structured cabling — it’s one of the more consistently in-demand niches in the San Antonio market right now.
