Site reliability engineers

A site reliability engineer keeps production trustworthy: error budgets, on-call, capacity, and the incident response that follows when those fail. Conntal places senior SREs screened on real incidents by Ace8 and AceMQ practitioners who run enterprise platforms in production themselves.

ITOM and architecture

ServiceNow ITOM and enterprise architecture, scoped honestly.

ServiceNow ITOM developers

Conntal places ServiceNow developers for IT Operations Management work: Discovery, Service Mapping, Event Management and CMDB health.

Enterprise architects

Conntal places enterprise architects who have carried a decision through delivery rather than stopping at the diagram. Candidates are screened by Ace8 practitioners on a real estate decision with real constraints — cost, residency, existing debt — and on whether they can say no to their own preferred architecture.

Engagement

Every role, three ways.

01

Contract

A vetted engineer embedded in your team for a defined term.

Hourly, billed against an approved SOW. Most common for migrations, upgrades and capacity surges where the work has an end date.

Contract staffing
02

Contract-to-hire

Work together first, convert when it is obviously working.

A defined conversion window and a pre-agreed fee, so the decision to hire is a business decision rather than a negotiation.

Contract-to-hire staffing
03

Direct placement

A permanent hire, screened to the same standard.

One-time fee against first-year base. Used where the role is a long-term platform owner rather than project capacity.

Direct placement staffing

Tell us the role. A practitioner scopes it, not a recruiter.

Send the requirement — or the job description you are not happy with — and an engineer who runs this technology will tell you what is missing before we source anyone.
