Use a technical recruiter when a specific search needs expertise, reach or sustained attention that your team cannot currently provide. Hire directly when you have a clear brief, a credible candidate pipeline and the capacity to assess people well. Paying an agency will not resolve an unclear role or an interview process nobody owns.
That is Corellia Talent’s starting point. The right decision depends on the work to be done, not on a universal headcount threshold or the round you have just raised. A company can run most hiring internally and still need external help for one research, infrastructure or leadership search.
Identify the bottleneck before choosing the channel
The most useful first question is where the search is failing. Different problems call for different interventions.
| What is happening? | What to investigate first |
|---|---|
| Few relevant people enter the process | Brief quality, sourcing reach and the proposed package |
| Strong people decline a first conversation | Role positioning, working arrangement and credibility |
| Interviews happen but nobody progresses | Assessment criteria, interview design and feedback |
| Candidates reach the offer but decline | Compensation, scope, trust and the decision process |
| The search keeps stopping | Internal ownership and protected hiring time |
A specialist recruiter may help with several of these. But if the founder and technical lead disagree about the job, more introductions simply expose more people to the disagreement. Resolve the mandate before asking anyone to represent it.
For an early engineering hire, start with a written founding engineer brief. For leadership, define the mandate before choosing the title. Both make the decision about external support more concrete.
Hire directly when the route is already working
Direct hiring is a sensible choice when the team can consistently find and assess relevant people without external help. A trusted network, useful referrals and credible inbound applications may already provide enough candidates for a particular search.
Keep ownership explicit. Someone needs to manage outreach, answer questions, schedule interviews, collect feedback and keep candidates informed. Direct hiring is not free of work simply because there is no agency invoice.
Our recommendation is to test that capacity honestly. Write down who will do each activity and when. If the same engineering manager is expected to deliver a release, conduct every interview and maintain the candidate pipeline, decide which work has priority before the search starts.
You should also hire directly when the main challenge is explaining your company. Founders and technical leaders should remain involved in that conversation even when a recruiter supports the search. Nobody outside the business can replace a credible account of its product, trade-offs and working environment.
Use specialist help when the missing capability is clear
A technical recruiter is most useful when you can name what they will add. That may be understanding a narrow skill set, identifying people beyond your immediate network or keeping an important search moving while the team delivers other work.
A niche brief needs more than keyword matching. Ask a potential partner to explain the relevant work in plain language. For example, can they distinguish research engineering from product-focused AI engineering? Can they explain which requirements are essential and which could unnecessarily exclude a strong candidate? Our AI and research role guide provides a starting vocabulary.
Confidentiality can also justify external support. A leadership search may need controlled disclosure, agreed messaging and a clear record of who knows what. Document who owns the decisions and candidate communication throughout.
The investor guide from Octopus Ventures recommends external search for roles outside internal capabilities, including senior, technical and confidential appointments. Treat that as a capability test, not a rule that every technical hire requires an agency. [Source 1]
Urgency is a reason to organise, not to promise speed
An urgent hire needs an available decision-maker and a workable assessment process. A recruiter cannot create interview capacity, approve an unagreed package or guarantee that the right person can start immediately.
Before starting, agree who can change the brief, who approves the offer and how feedback will be handled. Explain the deadline and what creates it. A product milestone, a replacement and a temporary delivery gap may require different solutions.
If the work is time-bounded, consider whether contract or interim recruitment fits the need better than a rushed permanent hire. If the role is permanent, keep the long-term requirements visible even when the immediate deadline is pressing.
Multiple markets require an explicit plan
Hiring across London, New York and San Francisco needs clear ownership of each market. A recruiter’s reach in one city does not automatically establish relevant experience in the others.
Ask how the person running the search will handle local candidate expectations, working arrangements and scheduling. Clarify which roles can genuinely sit in any of the locations and which depend on proximity to a team or customer. Do not treat an employer’s office map as a substitute for a hiring plan.
Use our comparison guides for New York, San Francisco and London as starting points for your own due diligence. Confirm each firm’s current scope and terms directly.
Match the arrangement to the search
The commercial model should describe who does the work, what is delivered and when payment is due. Labels alone do not tell you how much attention a search will receive.
| Arrangement | General structure | What to clarify |
|---|---|---|
| Contingent | Payment is usually linked to a successful placement, under agreed terms | Payment trigger, exclusivity, candidate ownership and what happens if the hire leaves |
| Retained | The client commits to a defined search, commonly with payments at agreed stages | Research scope, milestones, responsible consultant, reporting and cancellation terms |
| Hybrid or engaged | A negotiated combination of upfront commitment and later payment | What each payment buys and how the balance is calculated |
| Embedded or project support | Recruiting capacity is supplied for a period or defined project | Deliverables, systems, handover and who owns the hiring decisions |
These are general descriptions, not Corellia’s price list or a substitute for reviewing the actual agreement. AESC’s guide distinguishes retained executive search, contingent recruiting and internal talent acquisition; it also highlights specialism and geographic reach when selecting a firm. Its guidance concerns executive search, so do not assume every engineering assignment must follow that model. [Source 2]
Avoid buying on a headline fee alone. Compare the written scope, communication and accountability as well as the cost. Equally, a more expensive or exclusive arrangement is not proof of better judgement.
Ask practical questions before committing
A useful recruiter should be able to explain their proposed work without relying on a large database claim. Corellia recommends asking:
- Who will run the search and speak with candidates?
- Which parts of this brief would you challenge before starting?
- How will you distinguish relevant experience from an impressive company name?
- What information will accompany each introduction?
- How will we handle candidates already known to us?
- What does progress reporting show when the search is not producing suitable people?
- What are the payment, cancellation, replacement or rebate terms?
- How will you obtain permission to share candidate information and manage confidentiality?
Ask for relevant evidence where it can be shared appropriately. Respect confidentiality: anonymised experience may be more appropriate than client names. Past placements by an individual and placements made by the present firm are different claims and should be described accurately.
Know when to pause before hiring a recruiter
Pause when the role is unapproved, the decision-maker is unavailable or the compensation discussion has not happened. Also pause when the team wants someone to solve contradictory requirements without changing any of them.
A clear decision is better than a search that quietly drifts. Agree what would make direct hiring sufficient, what external support must add and what evidence will lead you to adjust the plan. That gives both the company and the recruiter a meaningful basis for reviewing progress.
For an ongoing volume of hiring, assess whether an internal recruiting capability would make more sense over time. For a specific gap, external support may complement an existing team. Neither choice needs to become a permanent ideology.
