Tech Hiring Channels Compared

5-Channel Comparison Matrix

In-House Direct Sourcing

The true cost of internal recruiting includes: internal recruiter salary allocation ($4,000-$6,000 per hire at 15 hires/year), ATS subscription ($200-$500/month allocated), LinkedIn Recruiter seat ($8,000-$12,000/year allocated), job board postings ($500-$2,000 per role), and sourcing tools ($100-$300/month). The total comes to approximately $6,000-$10,000 per hire, but this drops significantly at higher volume because fixed costs are spread across more hires. At 30+ hires per year, per-hire cost can drop below $4,000. The main advantage is control: you own the candidate relationship, build an employer brand, and accumulate institutional knowledge about what works. The disadvantage is speed -- building a sourcing pipeline takes time, and you bear the full cost of failed searches. Best for: companies with 15+ hires per year, strong employer brands, and roles where candidate supply is adequate. Not recommended for: urgent hires, senior/executive roles, or highly specialised positions where your internal recruiter lacks domain network.

Contingency Agency

Contingency agencies are the default choice for most tech hiring because they have zero upfront cost -- you pay only when a hire is made. The fee for a $150K role ranges from $22,500 to $37,500 depending on role scarcity and your negotiation. The advantages are speed (pre-built candidate pools), specialist knowledge (agencies focused on specific tech disciplines), and risk-free engagement (no fee if no hire). The disadvantages are incentive misalignment (agencies are incentivised to fill roles quickly rather than well), resume flooding (sending many marginally qualified candidates to increase hit rate), and the highest per-hire cost among non-retained models. Quality metrics show 74% 12-month retention for agency hires versus 82% for direct sourcing, though this gap narrows with specialised agencies that have strong tech domain knowledge. Best for: individual mid-level roles, companies without internal recruiting teams, standard tech roles with adequate candidate supply.

Retained Search

Retained search firms charge more because they invest significantly more time per search -- typically 100-200 hours versus 20-40 for contingency agencies. The fee is paid in three instalments (engagement, shortlist presentation, and hire) regardless of outcome, which aligns the firm's incentive toward quality over speed. For a $200K senior engineering role, retained fees range from $50,000 to $70,000. The quality premium is measurable: retained hires show 88% 12-month retention versus 74% for contingency, and higher performance ratings at the 1-year mark. Retained firms also conduct more thorough reference checks, assess cultural fit more deeply, and often coach both candidate and client through the offer process to reduce rejection risk. Best for: VP and C-suite roles, CISO and security leadership, senior SRE and principal engineers, any role where the candidate pool has fewer than 200 qualified professionals nationally.

RPO (Recruitment Process Outsourcing)

RPO providers take ownership of part or all of your recruitment process, bringing dedicated recruiters, technology, and process expertise. The cost structure typically combines a monthly management fee ($5,000-$15,000) with a per-hire fee ($3,000-$8,000), making it the most cost-effective model at scale. A company hiring 20 people per year through RPO might pay $160,000 total ($60K management fee + $100K in per-hire fees) versus $600,000+ through contingency agencies at 20% average fee. RPO providers also bring process improvements: standardised interview frameworks, structured feedback systems, and data-driven optimisation that improve quality and reduce time-to-fill over time. The minimum commitment (typically 10-20 hires or 12 months) and setup time (4-8 weeks) make RPO impractical for small companies. Best for: companies with 15+ tech hires per year, scaling startups, companies with inconsistent hiring processes that need professionalisation.

Contractor-to-Hire

The contractor-to-hire model places a contractor through a staffing firm at 30-50% markup on the hourly rate for 3-6 months, followed by conversion to full-time with a one-time conversion fee of $5,000-$15,000. For a role that would pay $72/hour ($150K salary equivalent), the contractor rate is $94-$108/hour. A 4-month trial costs $62,000-$72,000 in contractor payments plus $10,000 conversion fee, totalling $72,000-$82,000 -- more expensive than direct hire in raw cost but with dramatically reduced bad-hire risk because you have evaluated 4 months of actual work output. The immediate start (2-5 days versus 52+ days for a full-time search) also eliminates vacancy cost, which can offset the premium. Best for: urgent needs where vacancy cost exceeds $500/day, uncertain headcount situations, roles where technical fit is hard to assess in interviews.

Decision Framework

Choosing the right hiring channel is a function of four variables: budget, timeline, volume, and role scarcity. Use this framework to match your situation to the optimal channel. In practice, most companies use a mix of channels -- direct sourcing for common roles, agencies for scarce specialisations, and RPO when scaling.
