Most founders treat the first technical hire as a single move: find a senior engineer, or stay stuck. So they open a full-time role, spend three months interviewing, and hand the most important early decisions to whoever says yes first. The framing is wrong. The question is not who to hire full-time. It is what shape of help actually fits the next six months.
The full-time default is expensive and rarely right
A full-time first engineer is a year of salary, an equity grant, and a long onboarding bet on one person, made at the exact moment you know the least about what you are building. If the product pivots, and early products almost always do, you now have a specialist pointed at the wrong problem and a separation conversation you do not want to have.
The full-time hire is the right instrument when the work is continuous, the direction is stable, and you need someone in the building every day owning delivery. Before that, you are usually paying for optionality you then throw away.
Three lighter shapes protect your runway and keep you reversible:
- A senior contractor for a defined build. You scope a concrete chunk of work, pay for the outcome, and keep the option to part ways cleanly when it ships. No equity, no severance, no year-long commitment.
- A fractional technical lead for the decisions. Someone senior who owns architecture, vendor selection, and the hiring plan a few days a week, without the full-time price. That is the role I play for founders.
- A small bench. A fractional lead plus one or two trusted builders who ship under that lead's direction. You get judgment and execution without a single point of failure sitting on payroll.
Match the shape to the risk, not the title
The useful question is where your real risk sits. If your risk is that you cannot tell good work from bad, that you are paying developers and hoping, then what you need first is judgment, not more hands. A senior lead between you and the work pays for itself in the first month, often by stopping a build that did not need to happen.
If your risk is throughput, the direction is clear and you simply need more shipped, then a contractor or a bench is cheaper and more flexible than a full-time hire you cannot easily reverse.
The mistake I watch founders make over and over is hiring for throughput when their actual problem is judgment. They add an engineer, the engineer builds exactly what they are told, and two quarters later the founder is paying more for the same uncertainty. Screening for the right first person is its own hard problem, and I wrote about that in your first senior engineer is a bet. The prior question, the one founders skip, is whether a permanent hire is the right instrument at all.
How to structure the lighter version well
If you go the contractor or bench route, write the engagement down like you mean it. Define the outcome, not the hours. Agree on what done looks like, who owns the code and the credentials, and how either side ends it. Keep the contract short enough that walking away is genuinely cheap. The whole advantage of this path is reversibility, and a vague open-ended retainer quietly destroys it.
Then keep one senior person accountable for the work, even if you are not that person. Unowned contracting is the worst of both worlds: you pay for output nobody is steering, and you find out it was wrong when it is expensive to fix.
When to actually commit full-time
Convert to a full-time hire when three things are true at once. The work is continuous and predictable enough to keep one person busy and accountable. The direction is stable enough that you are not betting a year of salary on a guess. And you have enough technical judgment in the room, your own or borrowed, to evaluate the candidate and onboard them well. Hiring a full-time engineer before you can evaluate one is how founders end up a year behind, with architecture they are now stuck with and a hire they cannot honestly assess.
Until all three hold, the contractor-or-bench path keeps you reversible, and reversibility is the whole game this early. Every commitment you can unwind cheaply is a commitment you can make faster.
FAQ
Is a contractor more expensive than an employee?
Per hour, usually yes. Per outcome, usually no. A contractor you can end cleanly when a build ships is cheaper than a full-time hire you carry through a pivot, once you add the equity and the severance. Price the total commitment, not the hourly rate.
Will a contractor disappear when I need them most?
It is a real risk, which is why the fractional-lead-plus-bench shape exists. The lead owns continuity and the relationship, so no single contractor is load-bearing. You are buying a managed team, not a lone freelancer.
How do I know when to switch to full-time?
When you keep wishing the person were in the building every day, the direction has held for a couple of quarters, and you can write the job spec without hand-waving. If you cannot describe the role crisply, you are not ready, and a 20-minute fit call is a cheap way to pressure-test that before you commit a year of salary to it.
