At some point every growing startup has the same conversation: engineering needs a leader who isn't the founder. The question that trips people up isn't whether they need engineering leadership, it's whether they need to hire a full-time executive for it right now.
That's a bigger decision than it looks like. A full-time Head of Engineering is a six-figure-plus hire, a multi-month search, and a bet on someone before you fully know what the role needs to be yet. Get the timing wrong in either direction, hire too early or wait too long, and it costs you.
What you're actually short on
"We need engineering leadership" usually means one of a few different things, and they don't all require the same fix:
- Team creation and org design — you've outgrown one flat team and need to split into teams with real ownership boundaries.
- Hiring — technical hiring is bottlenecked on you, in-house or distributed, and it's slowing growth.
- Management coaching — you have engineers who could grow into leads, but nobody is developing them into that role.
- Delivery process — sprints slip, priorities thrash, and there's no consistent way work gets planned and shipped.
- Performance management — reviews are inconsistent or nonexistent, and underperformance goes unaddressed too long.
A full-time hire buys you all five, eventually, once they're ramped. But if what you actually need right now is one or two of these fixed well, you're paying for a lot of ramp time to get there.
The case for fractional first
Fractional engineering leadership, someone embedded 10-20 hours a week, makes sense when:
- You're not sure yet what the role needs to be. Getting the function running for a few months tells you what you're actually hiring for, which makes the eventual full-time search sharper and faster.
- You need the fixes now, not after a 3-6 month search. Hiring, delivery, and org design problems compound while the role sits open.
- You're not ready to manage an executive. A full-time leadership hire needs someone experienced enough to onboard and calibrate them. If that's not in place yet, a fractional lead can help build it.
- The team is 5 to 15 people. Below that, you often don't need a dedicated leadership hire of any kind yet. Above roughly 15-25, the case for full-time gets much stronger.
The case for full-time
Fractional isn't the permanent answer for every team. It's usually time to hire full-time when:
- The team is consistently above 20-25 engineers, or heading there within the next two quarters.
- The leadership need has stopped being "get these five things fixed" and become "own this function indefinitely."
- You've done a fractional engagement long enough to know exactly what you're hiring for, which makes the full-time search materially faster and lower-risk.
A model that doesn't force the choice early
The two options aren't mutually exclusive, and treating them as an either-or is what causes founders to stall on the decision entirely. Fractional engineering leadership now, with a full-time hire later once the org and the role are clear, is a normal path, not a compromise. It also means the eventual full-time hire walks into a team with a working hiring process, a real org structure, and management practices already in place, instead of having to build all of that from zero on top of also being new.
If you're trying to figure out which side of this you're on, that's the first thing we work through in an engineering scale consultation: a clear assessment of your team, and a straight answer on what you actually need next.
