Infrastructure Engineer
Inside IR35, £500 P/D
Active SC would be advantageous
Predominately remote
6 month contract, scope to extend
Overview
We are looking for an Infrastructure Engineer to support a large-scale programme moving applications and services from legacy into cloud and managed hosting environments.
The work is hands-on and delivery focused, with an emphasis on safe, structured migration and minimal disruption to live services. This is a transition role rather than a cloud transformation position, with engineers working within established migration approaches and patterns.
What You'll Do
Support the migration of applications and services from legacy applications into target hosting environments.
Apply established migration approaches and patterns to individual services.
Support service discovery, dependency mapping and environment readiness.
Work across development, test and production environments to coordinate migration activity.
Complete infrastructure and configuration changes required to support migration.
Help re-establish and validate connectivity, including network, firewall and service dependencies.
Support rehearsals, cutovers, smoke testing and post-migration validation.
Identify risks, support mitigations and contribute to rollback planning where required.
Collaborate with architects, application teams, platform teams, security specialists and service SMEs to unblock delivery. Essential Skills and Experience
Strong infrastructure engineering or systems-administration background with hands-on delivery experience.
Experience supporting application, infrastructure or hosting migrations.
Solid understanding of Linux and/or Windows systems, networking and environment configuration.
Ability to work across multiple environments and apply controlled change safely.
Experience supporting live services in complex enterprise environments.
Experience troubleshooting infrastructure, configuration and connectivity issues.
Clear communication skills and the ability to work effectively across technical teams.
Pragmatic and delivery focused, with the ability to work with legacy technology and incomplete information.
Desirable
Cloud infrastructure experience.
Experience supporting large-scale hosting migration programmes.
Exposure to Infrastructure as Code, such as Terraform or CloudFormation.
CI/CD pipeline experience, such as GitLab, Jenkins or Bamboo.
Scripting skills using Bash, Python or PowerShell.
Experience with VMware or comparable virtualisation platforms.
Understanding of DNS, routing, firewalls, load balancing and secure connectivity.
Exposure to legacy application-hosting technologies, middleware or databases.
Experience of migration rehearsals, production cutovers, rollback and early-life support.
Current or transferable security clearance.
What We're Looking For
Delivery focus: gets services moved safely and at pace.
Pragmatic mindset: works effectively with existing systems rather than seeking to redesign them.
Good judgement under pressure, particularly around risk and controlled change.
Comfortable operating across multiple teams and mixed legacy environments.
Willing to complete detailed, transactional migration work including configuration, validation and documentation.
Positive team player who contributes to a strong engineering culture
