Side-by-side hiring data for Docker and Kubernetes - salary bands, ecosystem skills, what each engineer actually ships, and how to brief Haystack for either.
Engineers who build small, secure, reproducible images by default.
Kubernetes engineers who design clusters as products, not pets.
Both Docker and Kubernetes have active talent pools on Haystack. We see first shortlists for Docker and Kubernetes land within 24 hours of kick-off, with the median Docker hire closing in 14-21 days alongside comparable Kubernetes roles.
Mid-level Docker engineers anchor around £70k–£95k UK base, with seniors reaching £100k–£140k. Kubernetes engineers sit around £85k–£110k mid and £115k–£160k senior. German bands run 5-20% higher in EUR and US bands 40-50% higher in USD.
For Docker we look for working experience with Kubernetes, BuildKit, Trivy. For Kubernetes the equivalents are Docker, Terraform, Helm. Both ecosystems get surfaced on every Haystack profile so you can filter on exact tooling.
Often yes - particularly when both stacks live in the same category (DevOps & Cloud vs DevOps & Cloud). On Haystack we let you require both as primary or secondary skills; senior generalists typically carry one as their main stack and one as supporting.
Pick on hiring depth, your team's current strengths and the ecosystem fit. Docker suits multi-stage dockerfiles that produce minimal images; Kubernetes suits multi-tenant platforms on eks, gke or aks. We can shortlist both in parallel so you can interview against the same brief.
Yes - the full ladder from junior through staff/principal in both Docker and Kubernetes. The kick-off call captures the level and shipped-work bar you need, and shortlists are filtered accordingly.
Tell us the role, level and salary band. We'll send shortlists for either stack within 24 hours.
