The 5-step process

Each step has a clear owner, a typical duration and a deliverable. Run it like a sprint.

  1. 01

    Define the role and must-have skills

    Day 0 · 1 hr

    Agree the 3–5 non-negotiable skills before sourcing. For a devops engineer, that's typically AWS, GCP, Azure, Kubernetes plus demonstrable experience shipping production systems.

  2. 02

    Decide on level, comp, and working pattern

    Day 0 · 30 min

    Mid-level devops engineers earn around £72k–£95k; senior hires reach £100k–£140k. Confirm hybrid/remote expectations upfront - it's the single biggest deal-breaker on offers.

  3. 03

    Source vetted candidates

    Day 1

    Skip cold sourcing. Haystack matches you with pre-vetted devops engineers actively interviewing, with skills, salary and notice period verified upfront.

  4. 04

    Run a focused 2–3 stage process

    Day 2–10

    Keep it tight: 30-min intro, technical deep-dive, and a final round with team and leadership. Avoid take-homes longer than 2 hours - top candidates won't engage.

  5. 05

    Reference, offer, and onboard

    Day 10–14

    Move fast on offer once a decision is made. Senior devops engineers often have multiple processes running; a 24–48 hour offer window is the new normal.

£72k–£95k

Mid-level base

Anchor your comp band around the mid-level number. A senior devops engineer reaches £100k–£140k; juniors start near £50k–£68k. Add ~10–15% for London and Berlin, and 25–40% for SF and NYC, where total comp dominates base.

Watch-outs

Common mistakes that kill devops engineer hires

Vague job description

Skills like "AWS" need years of experience and context. Specify it.

Too many interview rounds

Top candidates drop after the 3rd. Cap at 3, including final.

Lowballing on offer

Internal salaries go stale fast. Benchmark every 6 months - not yearly.

Skipping references

Live-coding catches what dialogue won't. Always do at least one paired session.

Slow offer turnaround

48 hours after final round is the upper bound. Faster wins the candidate.

No defined scorecard

Hiring 'gut feel' alone leads to inconsistent decisions across panels.

What a great devops engineer owns

Use this as your interview scorecard. Score each candidate 1–5 per item; calibrate as a panel.

  • Design and maintain cloud infrastructure as code
  • Own CI/CD pipelines, release tooling and deployment safety
  • Improve observability, alerting and incident response
  • Partner with engineering on developer experience
