NOW HIRING - PERFORMANCE TECHNICIAN

North Texas High Performance is looking for an experienced Performance Technician to join our team in Justin, Texas.
Tired of getting shafted on warranty time? Or Hours cut just to make a deal? That won't happen here.
Be part of our tight knit team, not just a number.

This is NOT a general repair shop.
No basic oil changes. No commuter car line work. No hack jobs. Fun stuff, projects, high dollar builds.

We build high-end performance vehicles, engine packages, swaps, suspension setups, fuel systems, driveline combinations, forced induction builds, cam packages, wheels/tires, brakes, dyno prep, and more.

If you take pride in your work, pay attention to details others miss, and actually care about doing things correctly the first time, we want to talk to you.

If you cut corners, constantly make excuses, need babysitting, or think “good enough” is acceptable, this is not the shop for you.

REQUIREMENTS:

• Minimum 3 years experience in a dealership or performance shop
• Own tools required
• Strong diagnostic and mechanical ability and fast learner
• Must be organized, dependable, and self-motivated
• Ability to work on late-model GM, Ford, and Dodge performance platforms
• Fabrication/wiring/tuning knowledge is a plus
• Quality and craftsmanship matter more than rushing jobs out the door

WHAT WE OFFER:

• Climate-controlled performance facility
• Multiple lifts and state-of-the-art equipment
• Mainline hub dyno on-site
• Performance-only environment
• Serious builds, serious customers, serious expectations
• Flag Hours Rate Based on Experience - Generous Employee discount program
• Opportunity to grow with one of the fastest-growing performance shops in North Texas

We are building a team of professionals, not just filling a position.

💥 PARTS ARE EASY. RESULTS AREN’T. 💥

Anyone can sell you a part.
Not everyone can show you what it actually does.

At SMG Speed Shop, we don’t just move boxes…
We test what we sell.

With our in-house dyno setup at NTHP, we’re able to:

✔ Validate real gains
✔ Compare setups back-to-back
✔ Cut through marketing claims
✔ Recommend what actually works

🧠 HERE’S THE DIFFERENCE 🧠

Two parts might claim the same horsepower…

But on the dyno?
Different power curves
Different drivability
Different results where it actually matters

🏁 THIS IS WHY WE DO IT 🏁

So when we recommend something, it’s not a guess
It’s not a trend

It’s based on real data, real testing, real results

💬 COMING SOON 💬

We’ll be posting real-world comparisons, gains, and data from parts we carry

No fluff. No guessing.

🚨 THIS IS WHERE THINGS GET SERIOUS 🚨

Anyone can sell parts…

Not everyone can prove they work.

That’s about to change.

With our sister shop North Texas High Performance bringing in a
Mainline ProHub 3000CCS Dyno…

We’re not just recommending our favorite combos anymore,

We’re putting to the TEST them. In-house. On OUR cars.

👇👇👇

✔️ Real SMG shop builds
✔️ Real dyno validation
✔️ Real before/after results
✔️ Real data backing what we sell

No more “this should work”

It either performs…

Or it doesn’t.

And you’ll see it first.

This dyno bolts directly to the axle and measures true drivetrain power

So when we post numbers…

They’re not inflated.
They’re not guessed.

They’re PROVEN.

This is the next evolution of SMG.

Parts ➝ Tested ➝ Validated ➝ Delivered

Landing next door at NTHP this June 🔥

You’ve trusted us for parts…

Now you’ll see exactly what they can do 👀

Our sister company North Texas High Performance is adding a
Mainline ProHub 3000CCS Dyno

That means:

✔️ Every combo we recommend can be validated on one of the most advanced dynos in the industry
✔️ Accurate, repeatable results (no tire slip, no inflated numbers)
✔️ Real-world simulation tuning—not just quick pulls

This isn’t your average dyno…

It bolts directly to the axle and measures true drivetrain output

If you’re building a serious setup—

This is the kind of equipment you WANT behind it.
