For a single-engineer engagement the math runs different from a multi-DevOps team build. One embedded DevOps engineer for a 3-month stabilization sprint = 480 hours at $90/hr ≈ $43,200. Compare against a 3-month MSP retainer at $12k/month plus per-incident charges (typical $45k–$60k all-in) or a US in-house hire at $227k loaded plus 90-day notice exposure. Solo embed wins decisively for one-platform, one-cluster scope under 6 months — once the work expands to multi-cluster strategy or a dedicated SRE rotation, the team-of-three model becomes the right tier instead.
