Job Description

Pierce is looking for a Senior Infrastructure Engineer to own and develop our production infrastructure as we scale and move toward a hybrid-cloud setup. You will take end-to-end responsibility across on-prem and cloud — from virtualization and storage to networking, observability, automation and disaster recovery — and help shape technical direction, not just operate it.

You will work within the Infrastructure & Operations team alongside sysadmins, DevOps engineers and IT technicians responsible for all of Pierce's IT operations — a distributed team based in Sweden and Poland.

The role is senior, permanent, full-time, and based in Stockholm.

Key responsibilities

• Operate and develop the virtualization and storage platform (VMware/ESXi on Cisco UCS, NetApp) and Linux/Windows / Active Directory environments
• Networking, firewalls and connectivity (VLANs, VPN) and edge/CDN (Cloudflare, Akamai)
• Drive the hybrid-cloud build-out (AWS and Azure)
• Build CI/CD, infrastructure-as-code and automation (GitLab/Jenkins, Ansible, Terraform, container registry, self-hosted runners)
• Own observability (Zabbix, ELK, Grafana)
• Own secrets and certificate lifecycle management (vault-based secrets at deploy time, automated certificate renewal)
• Contribute architecture and technical leadership — design decisions/ADRs (API gateway, Kubernetes networking, cloud organization design)
• Incident response and disaster-recovery ownership, including on-call during peak trading

Requirements

• At least 3 years' relevant professional experience in infrastructure/systems engineering at a qualified level
• Strong Linux, virtualization, networking, monitoring and automation skills
• Ability to work independently with senior-level ownership of complex production environments
