When a team needs more capacity, the first decision is not who to hire but how. The hiring model shapes cost, speed, commitment and risk. Choosing it deliberately avoids a lot of rework later.

Contract staffing

A professional joins for a defined period or project. In the US this is usually a W-2 contract through a staffing partner, or a corp-to-corp arrangement for independent consultants; the classification should follow how the work is actually done. More on how we run these engagements on our contract staffing page.

Works well when:

  • The need has a clear end date, such as a migration, launch or seasonal peak.
  • You need specialist skills you won't use continuously.
  • You need someone productive quickly and can define the work well.

Watch for: knowledge leaving when the contract ends. Plan documentation and handover from the start.

Contract-to-hire

A professional starts on contract with the intention of converting to a permanent role after an agreed period — typically three to six months. See contract-to-hire for how conversion terms are usually set.

Works well when:

  • The role is new and its shape may change.
  • Fit with the team is hard to judge from interviews alone.
  • You want to move quickly without committing to every permanent offer up front.

Watch for: unclear conversion criteria. Agree in advance what "success" looks like and when the review happens — candidates value that clarity too.

Direct hire

You hire someone permanently from day one.

Works well when:

  • The role is core to the business and long-term.
  • You are confident in the role definition.
  • You want to attract candidates who prioritise stability.

Watch for: longer time to fill for senior or specialist roles. Start early, and expect to approach people who aren't actively looking — the work described on our direct hire page.

A simple way to decide

Ask three questions:

  1. How long will this need last? Months points to contract; years points to direct hire.
  2. How certain is the role? If it may change, contract-to-hire keeps options open.
  3. How urgent is it? If someone is needed within weeks, contract or contract-to-hire is usually faster to arrange.

Many teams use more than one model at the same time.

A worked example

A mid-sized retailer is moving its ecommerce platform to the cloud over nine months and will need a permanent platform team afterwards.

  • Months 1–9: two contract cloud engineers with migration experience, brought in within weeks. Their statements of work include documentation and handover.
  • Month 2 onwards: a direct-hire search for a platform lead, who joins before the migration ends and shapes the permanent team.
  • Month 6: one contract-to-hire DevOps engineer, converted once the team's on-call model is settled.

No single model would have covered all three needs well. For technology roles in particular, IT staffing usually involves this kind of mix.

Have these ready: a role description, must-have versus nice-to-have skills, location or remote expectations, a compensation range and the interview process. A clear brief is the single biggest factor in a smooth search.

In short

Match the model to how long the need lasts, how settled the role is and how fast you need someone. Write the brief before you choose — it usually makes the choice obvious. If you'd like a second opinion on a role, start a conversation.
