Job description

Why this job is for you

You are a senior IT professional who combines deep technical expertise with a pragmatic, hands‑on mindset. You know that modern IT infrastructure is not just about uptime – it is about scalability, security, business continuity, and creating the right conditions for people and services to perform at their best.

You thrive in environments where you can take ownership end‑to‑end: from architecture and deployment to optimization, governance, and retirement. You are comfortable operating across both traditional on‑prem environments and modern cloud ecosystems, and you are motivated by solving complex challenges with long‑term value in mind.

You are eager to work in an international context with current footprint in Scandinavia and South America supporting a modern professional service delivery organization with customers across the globe.

Responsibilities

In this role, you will be a key contributor to strengthening and developing Knightec Group's core IT landscape. You will act as a subject matter expert and 3rd line escalation point, while also taking part in and in cases driving strategic infrastructure initiatives that improve resilience, reduce complexity, and position the business for a fast‑paced future.

Qualifications

• Engineering degree in IT or equivalent competence.
• At least 5+ years of experience in infrastructure, systems engineering, or platform‑focused IT roles.
• Strong hands‑on expertise in enterprise infrastructure across servers, storage, virtualization, networking, and cloud services.
• Strong experience with virtualisation (e.g. VMware, Proxmox, Nutanix, HyperV).
• Strong experience in networking (firewalls, switching, routing, micro segmentation, WiFi and related hardware).
• Strong experience with system administration in Windows Server and Linux (e.g. installation, patching, web servers, hardening, logging).
• Solid experience with Identity management (e.g. AD, EntraID, IAM, RBAC, SSO, User provisioning, PIM, PAM, Access tiering).
• Experience in backup, disaster recovery, and business continuity planning.
• A strong automation mindset and experience improving operational efficiency through scripting, standardisation, or infrastructure‑as‑code approaches.
• Experience with both infrastructure and system monitoring.
• A structured and security‑focused way of working, with sound judgement in change management and access control.
• The ability to document clearly, communicate effectively, and collaborate across technical and non‑technical stakeholder groups.
• Fluency in English, written and spoken.

Nice to Have

• Swedish is highly meritorious.
• Experience in the professional service industry, e.g. working as a consultant.
• Experience with any type of coding.
• Experience working in an international IT environment.
• Experience working with Azure and/or AWS in hybrid enterprise environments.

Practical Information

This is a permanent position with a six‑month probationary period. The candidate can be stationed in the offices we have in Stockholm (Solna), Göteborg (Lindholmen) or Sundsvall, but we embrace flexible working conditions with a hybrid model. Start date is as soon as possible or by agreement.
