You’ve got a hardware product to build and you need engineering help. Maybe you’re a startup without an in-house team. Maybe you’re a larger company that needs specialized expertise or overflow capacity. Either way, you’re shopping for a contract engineering firm.
Here’s what to look for — and what to watch out for.
What to Look For
1. Relevant Experience
“We’ve done medical devices” is different from “we’ve done your type of medical device.” Look for firms that have worked on similar products, in similar regulatory environments, at similar scales.
Ask for specifics:
- What similar products have you shipped?
- What was your role vs. the client’s role?
- Can I talk to those clients?
2. Senior Engineers, Not Bodies
Some firms will staff your project with junior engineers supervised by one senior person. That’s fine for simple work, but complex hardware needs experienced hands.
Ask:
- Who will actually do the work on my project?
- What’s their background?
- Can I meet them before signing?
3. Clear Communication Style
You’ll be working closely with these people for months. Their communication style matters.
Red flags:
- Slow to respond during the sales process (it won’t get better)
- Can’t explain technical concepts clearly
- Defensive when you ask hard questions
Green flags:
- Proactive updates before you ask
- Honest about what they don’t know
- Push back when your requirements don’t make sense
4. Realistic Timelines
If a firm promises everything faster and cheaper than everyone else, be skeptical. Either they don’t understand your project, or they’re planning to cut corners.
The best firms will tell you what’s actually realistic, even if it’s not what you want to hear.
5. Appropriate Scale
A 5-person shop might be perfect for a focused prototype sprint. A 200-person firm might be right for a complex full-development program. Match the firm to the project.
Bigger isn’t always better — you might get lost in a large firm’s portfolio. Smaller isn’t always better — you might exceed their capacity.
What to Watch Out For
The Upsell Machine
Some firms quote low to win the work, then “discover” additional scope once you’re locked in. Ask about their change order history. Talk to references about budget accuracy.
The Black Hole
“We’ll check in at the end of the project” is a red flag. Good firms provide regular visibility: weekly updates, working demos, incremental deliverables. You shouldn’t go months wondering what’s happening.
The Generalist Trap
“We do everything” often means “we’re not great at anything.” Look for firms with genuine depth in your domain, even if they’re not as broad.
The Brochure Portfolio
Pretty renderings and concept sketches aren’t the same as shipped products. Ask what actually made it to market. Ask about the failures, too — how they handle problems tells you more than their successes.
Questions to Ask
Before signing:
- Walk me through a recent project similar to mine
- What went wrong and how did you handle it?
- Who specifically will work on my project?
- How do you handle scope changes?
- What does your quality system look like?
- Can I talk to 2-3 recent clients?
The answers matter less than how they answer. Defensiveness, vagueness, or reluctance to provide references are all warning signs.
The Discovery Call
Most good firms offer a free initial consultation. Use it to:
- Explain your project and see if they ask good questions
- Understand their process and communication style
- Get a rough sense of timeline and budget
- Evaluate whether you want to work with these people
Trust your gut. If something feels off in the sales process, it won’t get better once they have your money.
