Fractional, Interim or Permanent Engineering Leadership?

Matt Gold · Founder, Re:Sourced|8 min read|

In short

Fractional engineering leadership is a senior leader working part of each week on an ongoing basis. Interim is a full-time leader for a fixed period. Permanent is the hire you build around. Fractional suits a diagnosis problem; permanent suits a team that needs someone accountable after the engagement ends.

A question comes up often enough in our conversations with founders that it deserves a straight answer: should we bring in fractional engineering leadership first, before we know exactly what the permanent role is?

We are paid when a permanent hire is made, so read what follows with that in mind. The honest answer is that sometimes fractional is the right call and a permanent search would be premature, and the useful thing is knowing which situation you are in.

Three things that get called the same name

These solve different problems, and most of the regret we see comes from buying one to solve the other's.

When fractional is the right answer

Fractional works when the problem is diagnosis rather than delivery. Some situations where it earns its fee:

When it is the wrong answer

Fractional breaks down when the team needs someone accountable past the end of the engagement. The signs:

Fractional buys you judgement. It does not buy you someone the team can rely on next quarter.

What each costs

Permanent engineering leadership is the easiest to price. In our guide to hiring a CTO or VP of Engineering, engineering managers run roughly AUD 200 to 250k base in 2026 and VP of Engineering roles at scale-ups and listed companies commonly run AUD 280 to 360k base, before equity. Startup CTO packages weight far more toward equity than cash.

Add superannuation, state payroll tax and other on-costs to get the real annual cost; the cost to hire calculator does this by state. One thing to know at leadership salaries: from 1 July 2026 the super guarantee applies only up to the maximum contribution base of $270,830 a year, so super on a salary above that is capped rather than a flat 12 per cent.

Fractional and interim pricing is quoted per day and varies widely with the person and the scope, so we are not going to put a single figure on it. What you can do is compare like for like. Take the day rate you have been quoted, multiply it by the days a week and the number of weeks you expect to need, and set that against the loaded cost of the permanent role. The day rate calculator converts between a day rate and an equivalent salary on Australian assumptions, which is the comparison that makes the decision clear.

A sequence that often works

For an early team where the permanent role is genuinely unclear, one pattern avoids both mistakes:

  1. A short fractional engagement with a defined output. Not open-ended advice. A written view on the architecture, the team and exactly what the permanent leader needs to be.
  2. That output becomes the brief. A permanent search built on an experienced leader's diagnosis is far faster and more accurate than one built on a founder's first guess.
  3. A clean handover. The fractional leader helps interview for their successor and then steps back. Engagements that blur into the permanent leader's first months tend to undermine them.

If that sounds like where you are, the structured intake we run on every search is designed to turn exactly that kind of diagnosis into a brief. And if the role has been open a while as you decide, the cost of vacancy calculator puts a number on the wait.

FAQ

What is the difference between fractional and interim engineering leadership?

A fractional leader works part of each week, commonly one to three days, on an ongoing basis and often alongside other clients. An interim leader works full time for a fixed period, typically to cover a gap or see a specific programme through. Fractional buys experienced judgement at lower cost; interim buys full-time presence without a permanent commitment.

When should a startup use a fractional CTO?

When the problem is diagnosis rather than delivery: the permanent role is not yet clear, a non-technical founder needs an independent technical view, the team is too small to need a full-time leader, or the engineering story needs tightening ahead of a raise. It is the wrong choice when the team needs a day-to-day manager or when delivery rather than direction is the problem.

How much does a VP of Engineering cost in Australia?

VP of Engineering roles at scale-ups and listed companies commonly run AUD 280 to 360k base in 2026, before equity, and engineering managers roughly AUD 200 to 250k. The real annual cost adds superannuation, state payroll tax and other on-costs. From 1 July 2026 the super guarantee applies only up to a maximum contribution base of $270,830 a year, so super is capped at leadership salaries.

Can a fractional leader help hire the permanent one?

Yes, and it is often the best use of the engagement. A fractional leader who has diagnosed the team is well placed to write the brief and interview candidates. It works best with a clean handover, where they step back once the permanent leader starts rather than overlapping for months.
