The short answer
Scope a staff augmentation request around the work, not the job title. State the outcome and what exists when the engagement ends, list hard constraints such as residency or clearance first, decide whether the engineer leads the change or executes it, and check that the skill combination you want actually exists in one person.
Most staffing requests fail before a single candidate is sourced. In our experience the brief usually asks for the wrong seniority, the wrong title, or a combination of skills that does not exist in one person — and every candidate that follows is measured against a target that was never achievable.
Scoping is the cheapest place to fix that. The order below matters: each step narrows the next.
Describe the work, not the title
Titles are the least reliable part of a brief. “Senior DevOps engineer” covers someone who maintains CI pipelines and someone who runs a multi-region Kubernetes estate. Describe the work instead: the system, the change you need made to it, and what done looks like. A migration from classic mirrored queues to quorum queues is a scope; “RabbitMQ experience” is not.
Put the hard constraints first
Data residency, security clearance, US-person requirements and client contractual terms are not preferences to weigh against rate. They are filters, and they shrink the pool before anything else is discussed. Stating them at the start avoids a shortlist of strong candidates who cannot do the work.
Decide whether the engineer leads or executes
The same platform skill at two levels of ownership is two different hires. An engineer who leads a change designs it, owns the risk and argues with stakeholders; an engineer who executes one works a plan someone else owns. Asking for a lead while budgeting for an executor is a common way a brief gets seniority wrong, and it is settled in the brief, not the interview.
Check the skill combination exists in one person
Briefs accrete. A role that starts as Kafka operations picks up Terraform, then a service mesh, then a data platform, until it describes a team. Each requirement is reasonable; together they describe someone who may not exist, or exists in such small numbers that the search stalls. For every skill, ask whether the work fails without it on day one. If not, it belongs under “nice to have”, or in a second role.
Say what happens when the engagement ends
Whether the work ends with an in-house team owning the result, or with the engineer staying on, changes both the right commercial model and the right candidate. Bounded change with an internal owner afterwards suits a contract; change that becomes ongoing ownership suits contract-to-hire; a permanent platform owner is a direct hire.
A brief that is ready to source
- 01The system and the change, described as work, with a definition of done.
- 02Hard constraints: residency, clearance, citizenship, contractual terms.
- 03Lead or execute, and who the engineer works with day to day.
- 04The skills the work cannot start without, separated from the ones it would merely benefit from.
- 05What exists, and who owns it, when the engagement ends.
Related questions
What should a staff augmentation request include?
The system and the change you need made to it, hard constraints such as residency or clearance, whether the engineer leads the change or executes it, the skills the work cannot start without, and what exists when the engagement ends. The job title matters less than any of these.
Why do staff augmentation searches stall?
Usually because the brief combines skills that rarely exist in one person, or asks for a lead while budgeting for an executor. Both are decided before sourcing starts, which makes scoping the cheapest place to fix them.
