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.

🚧 Behind the Scenes at SMG🚧

We’ve had a big influx of builds lately (TX2K season always does that 😅), so we wanted to take a second to explain how things work behind the scenes:

Every car in our shop is part of a carefully managed schedule that includes:

Parts ordering & delivery timing

Custom fabrication

Multiple builds at different stages

Balancing quick-turn jobs with long-term builds

So while you may see cars coming and going quickly, others may take longer depending on what’s involved.

⚠️ A quick heads up:

Unscheduled walk-ins, calls, and constant check-ins actually slow your build down.

When a tech has to stop mid-job:

Tools get put down

Work gets interrupted

Time gets lost (and it adds up fast)

📩 How we handle updates:

We send updates at real milestones, often with photos.

If you haven’t heard from us yet:
👉 It means your build is still progressing within the plan.

🤝 Want a detailed update or walkthrough?

We’re happy to do that — just schedule it with us so we can give you proper time and attention.

🏁 Our goal:

Not fast…
Right.

We’re building cars we’d put our own name on — because we do.

We appreciate everyone trusting us with their builds 🙌

New Shipping Policies announced and effective immediately.

Fraud Prevention & Signature Requirements

Due to the increasing number of fraudulent transactions and chargebacks, all orders shipping to California will require an ID-verified adult signature upon delivery. This requirement cannot be waived.

Additionally, any order where the billing address and shipping address do not match may be flagged for fraud review. Orders flagged by our fraud prevention system may require additional verification before they are released for shipment. This may include confirmation of billing details, identity verification, or other reasonable steps to ensure the transaction is legitimate.

If verification cannot be completed, SMG Speed Shop reserves the right to cancel and refund the order at our discretion in order to protect both the customer and our business from fraudulent activity.

We appreciate your understanding as these measures help protect all parties involved.
