The 5-step process
Each step has a clear owner, a typical duration and a deliverable. Run it like a sprint.
- 01
Define the role and must-have skills
Day 0 · 1 hrAgree the 3–5 non-negotiable skills before sourcing. For a network engineer, that's typically BGP, SD-WAN, AWS VPC, Cisco plus demonstrable experience shipping production systems.
- 02
Decide on level, comp, and working pattern
Day 0 · 30 minMid-level network engineers earn around £62k–£85k; senior hires reach £92k–£130k. Confirm hybrid/remote expectations upfront - it's the single biggest deal-breaker on offers.
- 03
Source vetted candidates
Day 1Skip cold sourcing. Haystack matches you with pre-vetted network engineers actively interviewing, with skills, salary and notice period verified upfront.
- 04
Run a focused 2–3 stage process
Day 2–10Keep 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.
- 05
Reference, offer, and onboard
Day 10–14Move fast on offer once a decision is made. Senior network engineers often have multiple processes running; a 24–48 hour offer window is the new normal.
£62k–£85k
Mid-level base
Anchor your comp band around the mid-level number. A senior network engineer reaches £92k–£130k; juniors start near £42k–£58k. Add ~10–15% for London and Berlin, and 25–40% for SF and NYC, where total comp dominates base.

Common mistakes that kill network engineer hires
Vague job description
Skills like "BGP" 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 network engineer owns
Use this as your interview scorecard. Score each candidate 1–5 per item; calibrate as a panel.
- Design and operate hybrid cloud networks
- Own routing, peering and edge security
- Drive automation across network infrastructure
- Partner with platform on Kubernetes networking
Deep dive
The network engineer hiring playbook
Network Engineer specialist or generalist - which should you hire?
The honest answer depends on the half-life of your network engineer surface area. If you expect to keep investing in BGP and SD-WAN work over the next 18-24 months, a specialist network engineer will out-deliver a generalist on day-30 throughput and stakeholder confidence.
If your team is under ten people, or network engineer responsibilities are spread across two or three roles already, hire a strong generalist who has shipped this work in anger at least twice. The cross-disciplinary pattern recognition will pay for itself the first time priorities collide.
On Haystack we surface both - filtered by whether the candidate self-identifies as a network engineer specialist and verified against their last two roles. Expect to pay around £62k–£85k for a mid-level UK hire, scaling toward £92k–£130k for senior.
What strong network engineers actually bring
A great network engineer is not the one with the longest CV - it is the one who has owned a hard BGP call and changed how they work because of how it landed. Across the devops hires we have placed in 2025-2026, the same patterns keep showing up.
- An opinion on what NOT to do with BGP, backed by an example where adding it would have hurt the team.
- Network Engineers who pair SD-WAN depth with cross-functional fluency - they bring product, design and data into their decisions, not just engineering.
- A written 30/60/90 plan in week one, anchored to BGP delivery milestones rather than ramp-up vanity metrics.
- Versioned, observable network engineer work - measurable outputs, structured logs of decisions, and a clear rollback path on every change.
Red flags when interviewing network engineers
Every discipline has its own pattern of plausible-sounding answers that fall apart in production. For network engineers, these are the patterns that most often correlate with a six-month regret hire on the employer side.
- Defines "senior network engineer" purely by years of experience, not by the scope of decisions they own.
- Lists SD-WAN on the CV but cannot describe a single trade-off they hit in production - all framework, no friction.
- Treats the network engineer role as a job title rather than a problem to solve - no opinion on what they would change about how the discipline is typically practised.
- Only ever worked on greenfield network engineer projects - inheriting a messy, half-built system is a different muscle.
What to expect in the first 30 days from a Haystack network engineer hire
By week one, the new network engineer should have shipped a small, low-risk artefact to production or a stakeholder - a docs fix, a small process change, a first review on someone else's work. The goal is to validate the loop, not to ship anything heroic.
By week two, the network engineer is shadowing the active workstreams, attending standups in observe-mode, and asking pointed questions about why specific decisions were made. If they are not asking those questions, the hire is going to plateau.
By day 30, they own one cleanly-scoped slice of the network engineer surface area, have published a public ramp-up doc, and are the named point of contact for stakeholders inside that slice. Every Haystack employer gets a structured onboarding template, so you are not reinventing the playbook each hire.
