Hiring Your First Engineer as a Non-Technical Founder

I get pulled into this conversation more than almost any other. A non-technical founder has raised a small round, has a clear vision, and now needs to hire an engineer to actually build the thing. The stakes are high: this person will shape your codebase, your culture, and quite possibly your runway. And you have no reliable way to evaluate whether they’re any good.

I’ve sat on both sides of this — as a Fractional CTO helping founders run these searches, and as an engineer being interviewed by people who couldn’t tell a database from a deployment. There are ways to do this well, even when you can’t read code.

What You’re Actually Hiring For

The first mistake is treating this hire as “an engineer.” It isn’t. Your first engineer is a co-founder in everything but title. They’re going to make a thousand decisions you’ll never see, and most of those decisions are about judgment, not syntax.

What you actually need is someone who can do four things well:

  • Translate your fuzzy product ideas into something shippable
  • Make pragmatic technical choices that won’t paint you into a corner
  • Communicate honestly when things are going badly
  • Work without the safety net of a senior engineer above them

 

Notice that “best coder” isn’t on the list. The best coder you can find is often the worst first hire — they want clean problems, not ambiguity.

How to Evaluate Someone You Can’t Technically Vet

You can’t fake your way into evaluating code. Don’t try. Instead, evaluate the things you actually can.

Have them walk you through a past project end-to-end. Not the tech, the decisions. Why this approach? What did you cut? What broke? A strong candidate will talk about tradeoffs naturally. A weak one will only talk about what they built.

Give them a real, ambiguous problem from your business. Not a leetcode puzzle. Something like “we need users to be able to upload documents and search them later — how would you approach the first version?” Listen for whether they ask about constraints, users, and timelines before jumping to a solution.

Ask what they would refuse to build. Engineers who can’t say no will build whatever you ask, including the things that will sink you.

Bring in a Technical Second Opinion

This is the part most founders skip, and it’s the cheapest insurance you can buy. Hire a Fractional CTO or trusted technical advisor for a few hours to sit in on the final round and review code samples. Someone who has been around long enough to recognize the patterns can save you from a hire that costs you a year.

I’ve done this for founders dozens of times. It usually takes one or two interviews to see whether a candidate is the real thing, and the cost is rounding error compared to the salary you’re about to commit to.

What to Avoid

A few patterns I’ve seen go badly:

  • Hiring someone whose last role was in a giant company, into a chaotic seed-stage environment
  • Optimizing for the cheapest contractor instead of the right person
  • Letting the candidate dictate the stack before understanding the product
  • Skipping reference checks because the conversation “felt great”

 

Each of these has cost a founder I know real money and real time.

Let’s Talk

If you’re a non-technical founder about to make your first engineering hire and want help running the process — defining the role, screening candidates, sitting in on technicals — that’s exactly the kind of work I do as a Fractional CTO. Reach out and let’s make sure your first hire is the one you wanted, not the one you settled for.
