What is recruitment process outsourcing, and why does it matter in life sciences?

Recruitment process outsourcing, often shortened to RPO, is an arrangement where a company transfers part or all of its recruitment activity to an external provider. That provider acts on your behalf, not as a third-party agency sending you CVs, but as an integrated part of how you hire.

For biotech, medtech, healthtech and diagnostics companies, this distinction matters enormously. You are often hiring for roles that barely exist elsewhere: regulatory affairs specialists, quality engineers with ISO 13485 experience, clinical data managers who understand adaptive trial design. Generic recruitment support rarely cuts it. RPO, done well, brings you a team that learns your science, your culture and your pipeline, then builds a hiring function around them.

The model has grown in popularity across life sciences precisely because headcount needs are rarely steady. A Series B biotech might need to go from twelve people to sixty in eighteen months. A medtech scaling into new European markets needs country-specific hiring expertise almost overnight. RPO gives you a way to build that capacity without hiring a large internal talent team you may not need forever.

The three main RPO models

Not all RPO looks the same. The right model depends on your size, your hiring volume and how much internal people infrastructure you already have.

Full RPO means the provider takes ownership of your entire recruitment function. They manage everything: job briefings, sourcing, screening, interview coordination, offer management and onboarding logistics. This suits companies that have no internal talent team and want to outsource the whole operation, or organisations going through very high-volume growth.

Selective RPO (sometimes called project RPO) covers specific roles, teams or hiring campaigns. You might bring in an RPO partner to handle all your clinical operations hires while your internal recruiter manages commercial roles. It is modular and useful when you have some internal capacity but need specialist support in a particular area.

Embedded RPO is where a consultant or small team sits inside your business, working alongside your hiring managers and leadership, often on-site or closely integrated into your Slack, your ATS and your weekly rhythms. They carry your employer brand, use your job titles, and behave in every meaningful way like a member of your team. This is the model Sajawo works in most often, and it deserves a closer look.

How embedded RPO differs from using a recruitment agency

This is one of the most common points of confusion, so it is worth being direct about it.

A recruitment agency works on contingency or retained fee structures. They hold a database of candidates, they represent multiple clients simultaneously, and their commercial incentive is to place candidates quickly. There is nothing inherently wrong with that model, but it creates a particular dynamic: the agency's loyalty is split, their knowledge of your company is surface-level, and you pay a percentage of salary per hire, which adds up fast.

An embedded RPO partner works exclusively for you during the engagement. They are not juggling your brief alongside twenty others. They learn your science, your values, your team dynamics and your longer-term workforce plan. They build talent pipelines rather than just filling vacancies. And because they are integrated into your business, they can push back when a job brief is unrealistic, flag when a hiring process is too slow, or spot patterns across your hiring that a transactional agency would never notice.

The cost model is also different. Embedded RPO is typically charged as a monthly retainer or day rate, rather than per-placement fees. For companies hiring more than a handful of people per year, this usually represents a meaningful saving, while also delivering better quality and consistency.

The honest pros and cons of RPO

RPO is not the right answer for every company at every stage. Here is a clear-eyed view of both sides.

Advantages:

  • You get specialist recruitment expertise without the overhead of a permanent talent team
  • Hiring becomes more consistent: same process, same candidate experience, same quality bar across every role
  • A good RPO partner will challenge poor hiring practices, not just execute them
  • You build institutional knowledge about your talent market that stays with you, not with a third-party agency
  • It scales up or down with your needs, which suits the lumpy growth patterns common in life sciences
  • You protect your employer brand, because the person hiring on your behalf is representing you, not themselves

Disadvantages:

  • It requires genuine partnership: if your hiring managers do not engage with the process, it will not work
  • The onboarding period takes time; a new embedded partner needs weeks to understand your science and culture properly
  • It is not suited to one-off, very low-volume hiring; if you are only making two or three hires a year, a retained search firm may be more appropriate
  • Choosing the wrong partner, one who does not understand life sciences or who brings a generic HR mindset, can waste significant time and money

What does RPO cost?

Cost varies considerably depending on model, scope and provider. A few principles are worth understanding.

Full RPO tends to be priced on a management fee basis, sometimes with a cost-per-hire element on top. Selective or project RPO may be charged per role or per campaign. Embedded RPO is usually a monthly retainer, reflecting the dedicated time and expertise being committed to your business.

When comparing RPO costs to agency fees, the comparison is not always obvious. Agency fees of fifteen to twenty-five per cent of salary per hire look manageable on a single role. Across twenty or thirty hires in a year, particularly at the salary levels common in life sciences, they become substantial. RPO retainers look higher on a monthly basis but typically deliver a lower total cost of hire at volume.

It is also worth factoring in the hidden costs of poor hiring: time spent by senior scientists and clinical leaders interviewing unsuitable candidates, roles that take six months to fill because the process was not well-managed, or early attrition because the brief was never properly defined. A good RPO partner reduces all of these.

Signs your company might be ready for RPO

Not every life sciences company needs RPO, but certain situations are strong signals that it is worth exploring.

You might be ready if:

  • You are scaling rapidly and your founders or senior team are spending significant time on hiring rather than science or commercial execution
  • You have tried agencies and found the quality inconsistent, the fees high, or the understanding of your sector shallow
  • You are entering a new market or geography and need hiring expertise you do not have internally
  • You are preparing for a fundraising round and need to demonstrate that you can build a team quickly and credibly
  • Your hiring process is inconsistent across departments, leading to variable candidate experience and poor data
  • You are growing your headcount by more than ten to fifteen people in a twelve-month period

How to choose the right RPO partner

The partner you choose will represent your company to every candidate they speak to. That is a significant responsibility. Here is what to look for.

Sector depth. Do they genuinely understand life sciences? Can they hold a credible conversation about your regulatory environment, your clinical stage or your product class? If they cannot, they will struggle to assess candidates or write compelling job briefs.

Transparency about how they work. A good partner will be clear about their process, their tools and their limitations. Be cautious of providers who are vague about methodology or who promise unrealistic timelines.

Cultural fit. You will be working closely with this person or team. Do they ask good questions about your culture? Do they listen? Do they push back thoughtfully when they disagree? These are the behaviours that will make the partnership productive.

References and track record. Ask to speak with previous clients in similar sectors or at similar stages. Understand what went well and what was difficult.

Flexibility. Life sciences companies change fast. Your RPO partner needs to be able to adapt as your needs evolve, not lock you into rigid structures that no longer fit.

Common pitfalls to avoid

Even well-intentioned RPO engagements can go wrong. The most frequent problems are:

  • Starting the engagement without clear goals or success metrics
  • Treating the RPO partner as a supplier rather than a partner, limiting their access to leadership and context
  • Choosing a provider based on price alone without assessing sector expertise
  • Expecting results immediately, without allowing time for proper onboarding and relationship-building
  • Failing to align internal hiring managers on the new process, leading to friction and inconsistency
