Direct answer
Cleared DevSecOps sourcing is hard because the best candidates often leave partial public breadcrumbs. Your job is not to verify clearance from the open web. Your job is to build a high-signal search lane and verify manually.
The signal stack
Layer platform tools, secure delivery language, GovCloud terms, RMF, ATO, NIST, FedRAMP, DoD, IC, SCIF, and donor-company context.
Operating notes
- Public clearance text is not verification.
- Search secure delivery evidence.
- Mine GovCon donor companies.
- Separate compliance profiles from hands-on platform engineers.
Donor companies
GovCon searches need donor maps. Different primes and subcontractors produce different slices of cleared technical talent.
False positives
Exclude help desk, desktop support, sales, trainer, bootcamp, student, and compliance-only profiles when the role needs hands-on infrastructure.
SourcingOS workflow
Use BooleanOS and X-Ray to build lanes, then use Candidate Search to keep evidence, missing details, and verification questions separate.

Can SourcingOS verify clearance?
No. It treats clearance mentions as unverified breadcrumbs and requires manual verification.
What should I loosen first?
Usually title variants, then location, then nice-to-have tools. Do not loosen non-negotiable clearance requirements without approval.
